DIY Floating Gardens in HortPark

If you drop by HortPark recently and took notice of the Water Garden located in front of the Visitor Center, you would have seen the floating gardens that have been set afloat on the water surface.

These floating gardens are a practical solution so that aquatic plants can still be displayed as the pond currently has a hard bottom with an undergravel filtration system installed at its base. There is neither an appropriate substrate at base nor containers can be put in to grow and display aquatic plants.

Each floating garden is created using readily available materials (see schematic diagram for details of construction). The floatation device took us a quite some time to source. It comprises a slab of extruded polystyrene board which is usually used for insulation of roofs. Unlike widely available white polystyrene boards used in art and craft, this board is made of dense polystyrene is more buoyant, resistant to wear and tear under the elements and does not absorb significant amount of water.

A selection of aquatic marginal plants, which naturally grow in waterlogged soils along a pond’s edge, with different growth forms, foliage textures and colours, is creatively combined to plant up these gardens that magically hover on the water surface. Of particular note is the use of North American Pitcher Plants (Sarracenia), which are colourful, insectivorous plants that grow in sunny and boggy sites in their native habitat.

Besides being decorative, floating gardens, in general, draw excess nutrients from the water column, especially if you feed your fish frequently. Fish waste that is produced in excess can lead to algae blooms. On a larger scale, such set-ups perform phyto-remediation work, where plants help to purify water in reservoirs, lakes and rivers.

Floating gardens also promote biodiversity. They provide shelter for fish and other aquatic organisms from the sun and predators. Dragonflies and damselflies are given a place to perch on and water birds can even roost in them if they are large enough!

SGF 2010 – My Home Garden Display – The Home Office

The Home Office area in the ‘My Home Garden’ display is a small one but it is packed with DIY gardening ideas that visitors can look forward to. Note that the office environment is often air-conditioned and that allows one to grow some cool-growing plants in the tropics. These include African violets, Pelargonium, a range of foliage begonias, hostas and even orchids!

One piece of furniture in this area is a work table with a clear glass top and below it hangs a platform that is illuminated with fluorescent lights. The lights, when turned on during office hours, can support the growth of a selection of low-light plants.

Much of the DIY ideas can be found on the hanging platform located below the glass panel! How about a hanging pot made from recycled Milo cans that is cladded with a cork board so each doubles up as a mini-notice board? You can pin notes onto it! Cheap and easy to make!

Marimo balls are quatic algae balls that hail from selected lakes around the world, the best known is Lake Ikan in Japan. These balls require bright light to grow and they make good candidates for displaying inside small recycled jam jars with laid with decorative mulch at the base! Remember to change the water of this mini aquatic garden once a week! This is another easy to construct bottle garden that serves as a very affordable gift idea.

The next idea is a rock bonsai which utilises brown volcanic rocks as planters. These volcanic rocks are easily available from local aquarium shops and often come with holes in them. These holes can be used to grow your plant. Shown here is a succulent plant that requires very little watering and little growing media to grow in. You can also use cacti species too. One thing to note is that there is a need to bring this succulent out to be exposed to direct sunlight periodically as fluorescent light alone is not sufficient to grow these sun-worshippers properly.

The next home office plant display idea is the ‘Mossy Landscape’. My team members bought square picture frames bought from IKEA, waterproofed the internal space of the frames and planted moss into them! What resulted was a neat-looking terrarium where moisture is kept in and all one needs to do is to spray some water to replenish the water supply every few weeks. Mosses are great candidates for this set-up as they do not grow too tall and thrive under bright light. The internal space is saturated with water vapour, making it conducive for mosses to grow.

The next idea is a product that was loaned to us by Candy Floriculture Pte Ltd, a local landscape industry partner. It would call this a very simple hydroculture cum aquaponics system that allows one to grow a range of indoor houseplants that require little nutrients to grow on a table top. Most of us would know what these plants are and they include common aroids and dracaenas which can virtually survive for long periods with just tap water! This system allows one to grow a plant as well as keep a pet fish in it! The fish’s waste materials serve as food for the plant, albiet in very small amounts only.

Going away from the table, we now focus on the displays on the window. If sunlight streams into your office desk, why not make a simple screen that doubles up as a mini vertical garden? Shown in this example, you can even hook on test tubes that hold water for some beautiful flowers! If you don’t fancy cut-flowers, you can attach various small airplant (Tillandsia) on this DIY curtain.

The last idea is to help plant-lovers create more space in a office to grow one’s plants (can also be extended to a home environment too!).  What you need is a ladder and you can hang a series of containers onto its rungs using metal container holders widely available from local nurseries. It is recommended to secure the upper end of the ladder onto the wall.

Locate plants that need more light in the middle so that sunshine that streams through the window can directly hit them. Those that need less light can be situated higher or lower along the length of the ladder. As you can imagine, by hanging potted plants on a ladder, you are actually constructing a vertical garden!

SGF 2010 – My Home Garden Display – Patio & Outdoor Garden

Called ‘My Home Garden’, the display put up by my colleagues at Hort Excellence division at the Singapore Garden Festival this year narrated a journey from the outdoors to the interior comforts of a home. It highlights the natural connection, beauty and excitement that greenery can exude into our living and working highrise environment.

We have selected a handful of living and working spaces which we thought people would like to have plants in. Visitors to ‘My Home Garden’ can look forward to a range of simple ‘do-it-yourself’ (DIY) ideas which they can bring home with them.

As one walks into the display, he or she will first see an intensively planted green oasis of a rooftop garden. Next is the patio where one moves to a semi-outdoor environment which serves as a transition space between the interior and the exterior. This is a comfortable zone from which one can enjoy the outdoor environment.

One of the first DIY ideas that one will find useful for rooftop garden would be a bird bath as shown above.  You can easily make one by stacking a series of pots in such a way where the rim of a pot fits just nicely around the base of another. A bit of mix and match needs to be done for this project and one may end up with a range of pots with very a very diverse look. You can overcome this by painting the entire column of pots with a single colour to achieve a more uniform look. To complete the project, put a saucer on top of the pot column which can be filled with water to make it a bird bath. We have used terracotta pots and saucer throughout for stability and durability. When this bird bath is in use, take note to change the water in the saucer to reduce the incidence of mosquito breeding!

Another DIY project for our garden fauna is a bird feeder. This DIY project is an environmentally-friendly one where that uses a range of recycled materials, in this case, a large, plastic drink botte and some kitchen culinary tools were used. Two wooden spathulas were inserted into the bottle via cuts and silts that have been cut into the bottle. Bird seeds trickle through the cleverly cut slits into the spathulas where birds can then feast on them. 

After walking through the rooftop garden, visitors who went next onto the patio might have noticed something interesting – a dog kennel with a green roof! The green roof was made possible by wrapping a wire mesh entirely with black plastic shade cloth. Between the shade cloth and wire mesh, we have included a layer of growing media made up of a soilless potting mix and coconut husk chunks. Holes were cut on the upperside and suitable plants (depending on the light conditions at the location where this kennel will be situated) are then inserted and grown.

FarmVille Singapore (Gardening on RazorTV)

A group of Green Culture Singapore forum members, namely, Casey, Ting Ting and myself were featured on RazorTV. RazorTV is an online television service by Straits Times that broadcasts live from Singapore Press Holding’s (SPH) Multimedia Centre. This series of video clips focussed on the growing of edibles and is part of the publicity effort for the Singapore Garden Festival 2010. One of my team members from Hort Outreach, Jin Hong, was also in the video where she showed how one can prepare some dishes using seed sprouts.

A great Garden DIY website

Recently, I came across a very informative website whilst searching for a range of gardening products related to work. I am impressed with this website called ‘Instructables’. Quoted from their website: “Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. The seeds of Instructables germinated at the MIT Media Lab as the future founders of Squid Labs built places to share their projects and help others.”

In Instructables, visitors ask questions and give praise for outstanding projects or offer suggestions for further improvements. This becomes somewhat like a discussion forum which allows a conversation between the project author and the rest of the community. There are even competitions organised to encourage more innovative ideas.

The DIY projects in Instructables are classified into various sections. What interest me most is the gardening DIY section under ‘Living’. There are step-by-step descriptions of gardening projects that fellow gardeners want to share. Like what was quoted in the Instructables website: “They are educational, inspirational, and often replicable.” A great number of projects in there involves the usage of recycled household materials.

Below are some projects that caught my eyes:

Natural Wood Raised Garden

Upside-Down Hanging Self-Watering Earth-Filled Box

Tip-Top Flower Pots: Maximize limited space to grow plants and flowers!

I shan’t reveal more. Do go pay a visit to the gardening section of Instructables website at http://www.instructables.com/living/gardening/

Do read more about Instructables’ Founder, Dr Eric J. Wilhelm, who is the founder and CEO of Instructables. He has a Ph.D. from MIT in Mechanical Engineering and he believes in making technology accessible through understanding, and strives to inspire others to learn as much as they can and share it with those around them.

A Spicy Christmas!

 The visitor to HortPark’s Lifestyle Corner this December would have noticed spices are used to make alternative  ornaments for the Christmas festive season. Instead of buying ready-made ones from commercial stores, some of us may want to take this opportunity to get everyone at home or in the office to come together to make some unique decorative items. You can also make use of this opportunity to teach your friends and kids where these spices come from and how they are used in flavouring food!

Spicy Christmas trees for the dinner table – all you need to do is to use hot silicone glue and stick various spices of your choice onto polystyrene cones. Seen here are ‘trees’ made from dried rose buds, cloves, cassia sticks, dried bay leaves, nutmeg and chillis!

If you have any faded baubles left over from previous years that are not nice enough for this year’s trees, do not throw them away! Reduce waste and turn them into new ornaments by dressing them up with spices! Shown above is an example of a bauble given a new lease of life after it has put on a new coat made up of star anise!

Another type of hanging ornament for the Christmas tree can be made from just a combination of spices. Shown above is a simple bundle of cassia sticks adorned with star anise and bay leaves which is strung with a golden string so that it can be hung up.

When making Christmas ornaments from spices, it is important to let your creative juices flow. Mix and match various spices to get the desired effect. Cassia sticks are very fragrant. Star anises with their star shape are great for the Christmas season. Dried chillis help to add a burst of red colour. Include also some dried bay leaves for the light green colour. Cloves are good for sticking into polystyrene cones and balls.

Besides looking great and unique, ornaments made from spices exude a delightful fragrance when they are made and displayed immediately. This is especially welcomed if you are using an artificial Christmas tree. These ornaments will last and in the tropics, store them in a air-tight bag with some silicon gel included to help absorb excess humidity after they are taken down after Christmas.

Floral Arrangement Talk cum Demo @ HortPark’s Wedding Fair

Besides being involved in decoration work for the Wedding Fair at HortPark that was held last Saturday, one of my team members, Pearl Ho, also conducted a floral arrangement talk cum demo session entitled ‘Bridal Bouquet Demonstration’.  Pearl introduced to her audience the diversity of flowers, foliages and various arrangement styles that can be used on one’s special day. She also taught all who were present on the importance of colour scheme.

In the beginning of her talk, Pearl presented a couple of traditional hand flower bouquets that are popular wedding must-haves. She also introduced a range of innovative, ‘green-themed’ ones which are created using potted plants such as Pilea ‘Moon Valley’ (noted for its textured leaves), variegated and all-green Ficus pumila, variegated Dischidia species and Episcia ‘Malaysian Gem’. These plants definitely last longer and are easier to maintain traditional bouquets made from cut flowers!

If your wedding reception has long tables, consider using floral displays with plants incorporated in them for a more lasting and unique arrangement. Shown here is a naturalistic display using a species of club moss for its interesting-looking foliage, Selaginella kraussiana ‘Brownii’,  which forms low, small clumps of whorled mounded leaves. Plants are potted up in small thumb pots which can serve as unconventional take-away souveniors for your guests.

Another table display, suitable for traditional round tables encountered in most receptions, is made up of orchids. Spider orchid flowers (Arachnis cultivar), shown in the example above, are also more-lasting flowers compared to many other imported flower species. They also lend a more tropical feel to the atmosphere. Foliage from the aparagus fern is used as a filler, which is also a durable floral material.

Shown above is a hanging arrangement created using spider orchids. Long-lasting, finely divided leaves from a common houseplant, the Ming Aralia (Polysicias fruticosa), are used as a filler in this fine example.

In line with a garden wedding in HortPark, Pearl transformed upturned coconut coir pots into wedding bells for a hanging arrangement which can be used to decorate a chair. These pots are very afforable and are available for sale in most plant nurseries. They are the tropical version of peat pots that are usually used to start new plants and then planted together in a final growing spot, which it will gradually degrade.

Lastly, do not despair if you missed this talk and demonstration! Pearl will be conducting similar workshops for registered groups in HortPark in 2010!

Decor Ideas for Christmas

Christmas is around the corner and some of us can get a headache over what to use to decorate a Christmas tree at home or in the office. Here are some decor ideas to share that have been put up in HortPark’s Lifestyle Corner for the month of December 2009.

For those of us who are environmentally-friendly and want to avoid buying an imported conifer Christmas tree, one can opt to use any large enough houseplant as a greener substitute. Below is our resident Ficus lyrata ‘Bambino’ which have been dressed for the festive occasion. The usual decorative items apply and we recycled last year’s assortment of colourful baubles for this tree to reinforce a green Christmas.

If you don’t have a plant that is large enough, go out and collect a bunch of fallen branches and twigs from the garden or park and use these to make your very unique and green Christmas arrangement? Proceed to dry them, then spray with gold and silver paint and finally display them in a tall glass container. My colleagues then went on to tie ribbons on the branches and also stuck dry leaves and some store-bought Christmas ornaments to complete the display. We kept in mind that all store-bought Christmas ornaments should be recycable for future use!

Below is another decor idea made using natural materials, which one of my friends shared with my team. If you grow luffas (Luffa cylindrica) in the garden, the sponges obtained from old fruits can also be used as a decorative item on your Christmas tree. All you need to do is to tie and stick a nice ribbon on it and put a string on the top so that you can hang it anywhere you desire!

If you still got some ornamental corn cobs lying around from Halloween, you can use these to adorn your Christmas wreaths! Those displayed in HortPark’s Lifestyle Corner were grown by my team and the cobs matured on the plant just in time for us to use them on the wreath. A warning to all – keep this wreath away from the reach of rodents! Our corn cobs were half eaten as we left them on our office table the night before!

When the festive season is around the corner, we never fail to see loads of nuts being put on sale in our local supermarkets. These oil seeds make very good and apt decor items for the home. Seen below are two styrofoam bells which my colleagues stuck various nuts onto them using hot silicone glue.

Below is another version you can make using almonds. My colleagues cut a star out from a piece of cork bark and then glued the almonds onto it. To add colour, we added red saga seeds onto each one of them. You can use other nuts available for sale in supermarkets to make a similar decor item which you can hang on the wall. These can be stored in a cool, dry place and they can be taken out and used for next year’s festive display.

If you noticed, all the decor items need a fair bit of effort to make them. Gather the entire family or office and join hands to create them. It is a good opportunity to come together whilst making these ornaments, we can all make it a point to catch up amidst the hectic work schedule in the past one year. Incorporate as much recycling ideas as you can into the creation of Christmas decor items to help reduce waste and save our environment during the festive season.

Green Living @ HortPark’s Lifestyle Corner (Part 2)

Here are more green ideas that my colleagues and I at HortPark would like to share with you… If you grow banana plants at home, why not harvest a few leaves to use as environmentally-friendly food receptacles instead of plastic ones? By doing this we can reduce the amount of waste generated whenever we have get-togethers or refreshments after company seminars or meetings. If there is a large crowd expected, one can consider buying stacks of banana leaves all cut to size from stalls in the wet market at Little India.

Kitchen scraps from plants such as vegetable clippings which are normally discarded can be used to make compost. Lately, vermi-composting is becoming a popular recycling method in Singapore. The product, Can-O-Worms (COW), is imported from Australia and marketed by Greenback Pte Ltd in Singapore. The COW kit is the black, stackable drum-like wormery which is small enough to fit into any household in Singapore (shown in the picture below).

The COW is a worm-driven recycling system designed for use inside the home. The scraps left over from preparing a meal are put into the COW where they are eaten by compost worms which live there. When done properly, the system is completely odourless and hygienic. As the scraps are eaten, they are converted to vermicast. Vermicast is an amazing product for stimulating healthy plant growth. The COW has a collector tank beneath where excess liquid is collected. This is vermicast solution and can be diluted 10 times and used as a very beneficial leaf spray. Vermicast solution will often cure fungal infestations and act as a deterrent to airborne pests and diseases.

Fruit skins can also be converted into environmentally-friendly detergent. The making of botanical detergents have also caught up in Singapore and one can make theirs using discarded fruit remains, brown sugar and water. The mixture is allowed to ferment and enzymes released during the process is said to be very efficient for cleaning chores at home. This can potentially reduce the use of synthetic detergents globally! Gardeners have also reported that such botanical enzymes are good to deter or eradicate small infestations of pests such as aphids on our garden plants!  Refer to this website for more information and following the steps on how you can make your own botanical enzyme detergent at home.

Green Living @ HortPark’s Lifestyle Corner (Part 1)

The month of November in Singapore coincides with the Clean and Green Singapore, which is an event that aims to inspire Singaporeans to care for and protect our living environment by adopting an environmentally-friendly lifestyle. In HortPark, my colleagues and I present a showcase at the Lifestyle Corner that shares some ideas and tips on how one do likewise at home.

To begin with something most of us are familiar with, what do a paper carton, a tin can and a plastic cup have in common? Well, they can all be used as plant pots! Common unwanted household items creatively transformed into useful gardening containers…

If you do a lot of take-aways in Singapore, don’t junk the plastic disposable food container! You can turn them into containers for germinating seeds, raising cuttings or even use them to make a self-watering container! All you need to do is to cut a hole in the lid that fits the plant pot you want to put in. Put in a cotton string that acts as a wick through the bottom of the pot and you are more or less done! Have a small reservoir of water at the base of the disposable food container that will supply your plant with water while you are away or busy with work. Water is drawn to the plant via capillary action!

This third idea is something I shared previously – the recycling of eggshells and eggtrays. Use eggshells as your planting pots and when you are ready to transplant your plant, all you need is to crush the eggshell and bury it into the planting hole! Plastic egg trays can be used as seed germinating trays too but paper ones are better! You can cut out each cell in a paper eggtray and plant the entire thing into the final growing location. Works something like the peat pot! Remember – eggshells add valuable calcium to the soil and you can grind eggshells into a fine powder and add that to your compost heap or soil which you grow your plants.
