Rare Bauhinia IDed!

A rare Bauhinia species in HortPark is in flower recently. With the help from the Singapore Botanic Gardens’ herbarium, the plant has been identified to be Bauhinia bracteata (Benth.) Baker subsp. bracteata. It is a Bauhinia species that is native to the Indochina region.

Most of the Baunhinia plants we see here are grown as ornamental trees and shrubs and may produce red, orange, yellow or white flowers. The flowers of Bauhinia bracteata (Benth.) Baker subsp. bracteata are greenish yellow and have a spidery appearance.

Its butterfly-shaped leaves are highly ornamental as well. The newly emerged, young leaves take on a red or orange tone which gradually turn green as they mature.

This flowering Baunhinia is located at Display Plot 26 at HortPark (33, Hyderabad Road, Singapore 119578). Many thanks to Cheow Kheng and the National Parks Board (NParks) for sharing this interesting piece of information and kind permission to reproduce the photographs on this blog.

Root Awakening (27 Sep 08)

The second instalment for the Root Awakening column in Straits Times Life! for the month of September 2008 was published today.

This instalment provided answers to three questions related to problems seen in the bamboo plant, hydrangea and the ficus tree.

An environmentally-friendly way to prevent mosquito breeding!

In Singapore, the breeding of mosquitoes has always been a public health issue. We were fed with the messages from the local National Environment Agency telling us to get rid of receptables that are capable of collecting water that will serve as breeding grounds for mosquitoes.

In my community garden in Serangoon North, we have been using bamboo poles as stakes and materials to build our trellis. They are those poles that we use here locally to hang our laundry to air dry. However, using  such bamboo poles in the garden may provide an avenue for potential mosquito breeding, especially if they are positioned vertically.

The node of each bamboo stem consists of a plate that seals the cross-section of the pole. Depending on how much excess of the stem that has been left after it has been cut, what results is a cylindrical container, which acts like a glass, capable of holding water. I have personally witnessed bamboo stakes collecting a sizeable volume of water after a rainstorm.

To prevent this from happening, I thought of ways to seal the ends of every vertically-positioned bamboo pole used in my garden. At first, I used plasticine to cover up the open cross-section. A resident living in my neighourhood told me I could fill the ends to the brim with soil. Soon after, one of my fellow community gardenrs, Mrs Yap, thought of a better idea.

She covered the ends of the bamboo using recycled Yakult bottles which are normally discarded after one finishes the drink. The Yakult bottle that Mrs Yap used seems to be slimmer than the usual ones that I encountered before. It apparently was able to fit so nicely on the laundry bamboo pole as the diameter of the mouth of the bottle was just slightly larger than the diameter of a typical bamboo pole. It looked as if the bottle had been pre-designed for this purpose!

Thanks to Mrs Yap who has come up with this environmentally-friendly method that can help to prevent mosquito breeding in our community garden. In doing so, we are doing our part, although a very small one, to reduce and recycle waste. It also saves us some money as well as we no longer need to buy plasticine from the stationary store to seal up the bamboo poles anymore!

Wonder what Watermelon Flowers look like?

I was at Richard’s community garden at Ivory Heights with Kate last Tuesday where I spotted a watermelon vine growing in one of the plots in the vegetable section. The vine was just starting to flower and there were a couple of cheerful yellow flowers in bloom near the tip of the vine.

The watermelon vine has lobated leaves instead of the usual almost cordate leaves that many other cucurbits have. The ancestor of today’s watermelon was said to have originated from the African desert. No wonder there is a saying that watermelons need to grown in sandy, well-drained soils! They seem to be able to tolerate some degree of drought too. They need to be grown in full direct sunshine for best results!

Unlike the large round fruits we often see, the flowers of the watermelon are quite small in fact, the diameter of each blossom was at most 2 cm across! Due to the rather small size of the flowers, they can be quite hard to see and find as they can get obscured by the large green leaves.

The male flowers, like the male flowers of other cucurbits, are devoid of any prominent baby fruit below the petals. They usually produced in abundance compared to the number of female flowers.

The female flower, on the other hand, has a prominent baby fruit below the petals, which makes it easy to differentiate from the male flowers. It is interesting to see that the young ovary below the petals are quite hairy! It even has the green stripes we see on the watermelon fruit!

In an organically-grown garden, watermelon flowers will have the necessary wildlife around to help with their pollination. Excessive use of chemical pesticides can kill off beneficial wildlife which are not only needed to help with pollination of flowers but will also eradicate pedatory ones that help to keep undesirable pest population in check.

If one notices poor fruit set in the garden despite the appearance of numerous female flowers, then it may be time for one to try hand-pollination of the female flowers. The procedure is pretty simple. One just has to go pick a male flower, strip off all its petals to reveal its pollen laden anthers and then brush the anthers against the center of a female flower where the pistil is located. One male flower can be used to pollinate several other female flowers.

It can be difficult to tell whether watermelon flowers are pollinated properly since all of them will have the petals closing up and shrivelling away after a day. One probably has to wait for a week or two and patiently watch the development of the fruit. As long as the ovary does not turn yellow and continues to swell at a rapid pace, the fruit is then on its way to become a mature, juicy watermelon!

Richard’s fellow gardener grows the watermelon on top of a trellis so as to prevent the fruits from touching the ground. He told me the base of their previous watermelon fruit was disfigured with brown marks. It appeared as if some creature tried to chew away parts of the rind surface. I reckoned that could have been caused by snails or slugs that roamed the garden when the weather was wet and rainy.

The National Library Garden Walks

I got my hands on an interesting pamphlet from the librarian after I finished my Mandarin gardening talk at the Possibility Room last Saturday. The pamphlet featured the new garden walks that visitors can register and then go to learn more about the highrise gardens located within the National Library Building.

When I first saw the planting schemes at the National Library Building a few years ago, I was quite impressed with the beautiful tropical gardens that have been created. I was also amazed then as I saw many sensitive tropical plants that are well known to hate being located in a drafty location are used as landscaping candidates in these gardens. Many of these can still be seen growing quite happily and blooming profusely despite being harrassed by the winds that blow through these highrise gardens!

The landscaped gardens were actually created to help maintain a cool environment for the new National Library Building. The National Library Building has a total 14 gardens and vegetation forms 35% of the total site area. The National Library Board was awarded the platinum Green Mark Award in 2005 for its excellent greening and environmentally-friendly work.

This garden tour would be good for anyone who wants to get some ideas to landscape his/her garden. The gardens in the National Library building are quite well-done and aesthetically-appealling and one should bring along a camera and snap as many pictures as he/she can. Do try to capture pictures of how plants are combined in a landscape that pleases your eyes as these will help you in coming up with your own gardenscape at home. Also note down the names of the plants, if any, that you like along the way and if not, snap pictures of them as that will help to let the nurseryman know what you want to buy when you are at the nursery.

 

My wish has been granted!

Twenty plus years. The exact length of time is something that I have lost count because I cannot remember when I exactly started to garden avidly. For more than two decades, I have been hoping for a private space that is in the boundary of my adobe to do gardening.

For an apartment dweller like me, I can only think of having a garden in a balcony. Although I have moved house two times in my life, both apartments did not have a conducive balcony. Although the second and current apartment that I lived in at Serangoon North has a balcony, the wierd thing about it was that the balcony was built inside the lift lobby! Although now I have a community garden, I still very much wanted a balcony or at least a sun-lit corridor where I can grow something near home.

My parents declared in an unexpected occasion this April that they wanted to shift out of the current apartment for a change in our living environment. After a few month’s worth of search, we finally decided to buy and move to a maisonnette apartment near Hougang Central.

We just got the keys to the apartment only yesterday after the final bits of paperwork had been completed. My family and I, brought along my dog to our new apartment to take a closer look at it and also to discuss the renovations that need to be undertaken to refurbish it. The gardening part of me kicked in and I went to survey the possible gardening areas’ availability of light and space.

The balcony of a typical maisonnette apartment in Singapore is unique among other publicly-built apartments. Because the apartment is a two-storeyed one, the balcony has a high ceiling that allows much natural light to stream into it. My balcony faces North and as a result, it would probably be receiving some direct sunshine only during the April to August period each year.

With this type of lighting conditions in mind, the types of plants that are suitable would be shade-loving ones like flame violets, prayer plants, gingers (such as my present favourite – Costus or Spiral Gingers), ferns and related allies, shade-loving orchids and palms. I intend to have a small round garden table in the balcony as well, so that my family can relax in a lush, tropical paradise.

The only places that I will have direct sunshine would be my bedroom and the stair-landings located just outside my apartment. The two areas will be receiving direct morning sunshine all year round as they face directly eastwards.

The thought in many people that their bedrooms will be receiving direct sunshine is a disaster to them because the room will be expected to heat up to a high temperature during the daytime, which can get quite unbearable and uncomfortable. I thought little of that because for five days a week and sometimes six, I would have departed home for school (and soon, work) or gardening very early in the day.  I told my parents to build a low, long row of cupboards along the window so that the top part of the cupboard can serve as a ledge where I can grow some smaller plants.

The two stair-landings located just outside my apartment also faced east and fortunately, they have not been occupied by anyone. I have been told by my new neighbours that this staircase located at the end of our corridor is hardly used. I thought of constructing some metal racks where I can line the along the ledge some pots where I can now grow various edible plants or any other sun-loving plants. 

It is now time to brainstorm for the design to be adopted for my balcony as well as what are types of plants that I must have. I must also go get a contractor to take the measurements of metal racks I want to have at the stair-landings. My dream has finally come true and the new gardening era for me has just began.

Mandarin Gardening Talk Part 3

This afternoon, I was at the Possibility Room of the Central Lending Library to deliver my third Mandarin gardening talk. It was part of a series of four gardening sharing sessions that focussed on the growing of edible plants. This was the first time that our gardening talks was held at the Possibility Room which was a comfortable and spacious venue that had a nice ambience. There is a beautiful tropical-themed garden in the courtyard located just next to the room.

Unlike the previous gardening talks that I have given, the room was probably only half-filled. Although the participation rate might seem rather disappointing, I thought the turnout was quite good considering the talk was not publicised in the newspapers. I saw quite a number of returning participants and one of my members from the Green Culture Singapore discussion forum, Richmond, came to support me. He even brought along his parents who had earlier visited my community garden at Serangoon North. One of the kind gestures of Richmond did which warmed my heart was to wear both the CIB and GCS collar pins on the sleeve of the Polo T-shirt he was wearing.

I touched on five main topics in the talk this afternoon. Four of them, namely, composting, mulching, watering and fertilising, were closely related to one another because compost can be used as mulch and a source of nutrients for plants. Mulch as layer on top of the soil can help to retain moisture at the plant’s roots and can help to reduce the need for frequent watering during hot weather. For audience who attended the talk, they should have noticed much emphasis had been put in by me to be environmentally friendly and we can recycle our kitchen and plants for use to make compost for use in the garden.

Because I have spotted some non-Chinese participants among the audience, I decided that I need to deliver the talk in both Mandarin and English. Giving bilingual talks can be quite a challenging task and I actually took another additional half hour to complete the talk but I hope I did it well enough to be able to benefit everyone. 

As usual, after every gardening talk that I had conducted, I got mobbed by the audience with their many pressing gardening questions. It has always been a pleasure to be able to help and give some advice to solve their problems. But as a result, I took up even more time and that would bring about some delay to the closing of the venue by the library staff on duty. My sincere thanks go to the library staff for bearing with me! Today was a weekend afterall!

Root Awakening (13 Sep 08)

I had been terribly busy lately but I managed to squeezed out some time to scan the the Root Awakening column published last Saturday.

This instalment provided some answers to three questions posed by the readers of Straits Times Life!. The first was about how to prevent pests from attacking developing mangoes that are still on the free and the other two were related to some problems often faced by novice apartment gardeners.

The light factor in gardening is an important aspect and many people took it for granted while others have no clue the amount of light that their plants need. This lack of knowledge has led to many failures I have encountered myself earlier on, as well as, many that I have seen or referred to. 

Dr Easaw Thomas’ Graden on the Business Times

Dr Easaw Thomas’ amazing garden was featured in the Business Times about two weeks ago and thanks to Cheow Kheng, I now got a copy of the article where I am now able to share with those gardeners who are keen in planting trees in their gardens.

Read on to find out what inspired Dr Thomas to plant 200 forest trees in his garden…

Why pay for a sculpted Japanese garden when you can DIY with local greenery?

Secret Garden

When you’re rebuilding or renovating your home, the question of what to do with your garden is usually answered by the landscape architect you hire. Sculpted trees. Check. Exotic plantings. Check. Weekly visits by gardener. Check. Do it yourself. What?

Easaw Thomas’ decision to DIY has turned his home in Wilby Road – dotted with good class bungalows turned into palatial homes – into a tropical jungle, and is a lush testament to his green thumb as well as one person’s effort to address global warming and conserve local, indigenous plants. Today, he wakes up to a low maintenance, equatorial rainforest garden that’s has been left to grow pretty much on its own.

“The burning of forests in Sumatra was a wake-up call which made me want to do something about the environment,” shares Dr Thomas, 63. To him, this was the only way to create an environment that would reduce the greenhouse effects – because of the great volume of carbon dioxide that rainforest trees absorb from the atmosphere.

“Singapore is also losing a lot of its native plants and trees,” he adds, so he makes it a point to pick plant varieties which are indigenous like syzygiums with its colour leaves (the red jambu tree belongs to this family, for example). “You have to take the context in which we live – we can’t be having Japanese gardens or temperate ones,” he points out. “Out context is one that favours an equatorial rainforest-like garden because the plant themselves grow better and they blend in with the surroundings.”

With these ideas in mind, Dr Thomas drew up his own design for his Wilby Road garden in the late 90’s that would be created around his existing 1930s house, open courtyard and pond. When the garden was done, some 200 forest trees towered around the 26.000 sq ft compound, layered with shorter fruit or flowering trees, followed by ground plants like ginger flower plants. “The other thing I wanted to have was some fragrance in the garden so I picked trees like the Michelia chempaca,” he rattles off, before showing you the variety of wild plants he picked from the jungle rather than commercial nurseries.

The garden is less than 10 years old, but it looks like the house was built within a decades’ old tropical forest. The house adds to the credibility – a 30’s style single-storey original wing and a newer, curved bedroom block that was virtually carved out of a hill on his land. The top of the hill slope serves as its roof – way before rooftop gardens became vogue. The rooftop garden has tea leaf bushes and flowering trees, and giant yam plants with their elephant ear-shaped leaves – which birds had seeded, says Dr Thomas, since he doesn’t recall planting them. The garden gets weekly visits from a few hornbills, in fact, a stamp of approval, if you wil;, for the natural rain forest eco-system he has created.

Kate’s Singapore Garden Tour

Kate’s tour of Singapore started early at 10 am. With the kind help from Mr Ng Cheow Kheng, she went on a visit to Richard’s community garden at Ivory Heights in Jurong East. Richard’s garden is a prize-winning garden at the recent Community in Bloom Awards.

During our an hour long visit, it was obvious that Kate was impressed with the many artistic statutes created by Richard himself, the colourful landscape of plants and deep commitment that has been dedicated to maintain the garden. Richard introduced to Kate to his community garden and shared his gardening experience as well as the process that was undertaken to convert a previously barren and disused plot of land to its present grandeur. The both of them exchanged contacts and we also took a group picture to commemorate the visit. 

We then proceeded to scenic Mount Faber for a hearty seafood lunch. During the journey to this popular tourist attraction, Cheow Kheng shared with Kate how he was involved in landscaping Mount Faber early during his career with then the Parks and Recreation Department, the predecessor of the National Parks Board (NParks).

After lunch we made our way back to the NParks Headquarters where we went on to explore the Singapore Botanic Gardens. Because Kate disclosed to me she was interested to see the vibrant colours of tropical plants, we brought her to take a look at the Ginger Garden where Lily and I shared with her some interesting facts about some of the ginger plants and members of the Zingiberales order that were in flower. Teresa, who was with us all the while, was admiring the exquisite beauty of the gingers while she was at the Ginger Garden. I noticed after this visit, Teresa is now hooked to a certain extent to these tropical plants too!

Kate and the rest of us later took a look at the Singapore Botanic Gardens’ Rain Forest Trail. The lushness of the tropical rain forest is something that is new to Kate from Adelaide, Australia. Although the entire tour of the rain forest trail was undertaken under the searing heat and unbearable humidity, I believe Kate had thoroughly enjoyed herself in the company of majestic towering trees that were all around her!

Due to time constraints, we were not able to completely explore the entire Singapore Botanic Gardens. After Cheow Kheng drove us back to Kate’s hotel at Little India, she presented Cheow Kheng with a beautiful thank you card that depicted a painting of the Sturt’s Desert Pea, an Australian native as well as a painted gum leaf. I would like to thank Cheow Kheng for spending the large part of the day where he introduced to Kate the Community in Bloom programme, arranged the community garden visit, shared the things that NParks are currently doing and for treating us to a fabulous lunch.

Kate’s last stop for the day was my community garden at Serangoon North. For the first time, she saw the plants and the garden with her own eyes. I took the opportunity to tell her about the concept of the garden as well as how it came about. She got to see the beautiful Musa ‘Morado’ banana tree which I had in my community garden that borne the red bananas that she bought for us to eat from the wet market. 

Despite the hot and dry weather today, various Oriental leafy vegetables, namely, pak choi, Chinese spinach, water spinach and Chinese mustard were all looking really good as if they were all prepared to meet Kate. Most of the other plants in the community garden sulked after losing much moisture to the heat.

By the time we finished with the visit to my community garden, everyone was clearly tired. Kate gave me a goodbye hug before Teresa drove her back to the hotel. We promised to continue to keep in touch via regular updates of our blogs and email correspondence. The duration of just one day to tour the Garden City of Singapore was clearly insufficient. I do hope Kate can come visit Singapore again in the near future. I hope that Lily and Teresa had enjoyed the time with Kate too.
