Every week, I spend a couple of hours at a primary school, helping out in the school garden.
It was during the dry season when I first visited the garden. We've had no rain for more than 3 months. All the trees and shrubs looked parched and miserable. The gound was bare and hard like concrete, even grass couldn't survive.
The first thing I did was to order a truck load of top soil to spread over the flower beds. Luckily the weather took a turn for the better and it began raining every week. The grass turned green and the trees flourished.
We began growing edibles in the once barren backyard. We planted lettuce, bak choi, spinach, brinjal, lady's fingers, radish, corn, turnips, onions and so forth. Something was soon troubling us. Many of the seedlings couldn't survive despite constant watering. The fluffy layer of topsoil soon became very dry and compacted. Some of the hardier plants like sweet corn, sweet basil and brinjal could survive, though they weren't exactly flourishing.
We sowed some cucumber seeds in two identical planter boxes placed side by side. The seedlings on the right box began growing very quickly and were soon creeping up the trellis.
The other one (below) fared badly right from the start. We couldn't figure out why though I had suspected it wasn't getting enough direct sunlight.
While working in the garden one day, it suddenly dawned on me that the garden is exposed to strong winds from the beach nearby. No wonder! The wind has been affecting the development of our plants.
The planter box of cucumbers on the right is protected by a large wall whereas the one on the left is not. That explains why they are developing so differently.
For me, it is an important discovery. I don't spend enough time at the school to understand the conditions. Even in my own patio garden, the amount of direct sunlight I get changes throughout the year, affecting the crop that I grow.
Now I know why the soil in the school yard is so parched. The wind strips away the moisture from the leaves and soil. It stunts the development of the plants.
The wind keeps bashing the sweet corn and lady's fingers until the roots are exposed, making the plants unstable. Needless to say, our spinach and lettuce couldn't survive at all. Only the sweet potato, yam and turnip seem pretty unaffected for now.
I'll have to rework the garden. Unfortunately, when it comes to growing edibles in a harsh environment like this, the choices are rather limited. Rosemary comes to mind but that area is probably too shady.
So we're working with shady, dry and windy condition here. Pretty hostile if you ask me.
Any suggestions would be appreciated.
