Growing Food in a Small Space

Hi,
Very practical idea this is for the smaller family with limited area.
I continue to grow all my leafy veges and green chillies off my beds made of wooden (used) planks.

Some tips coming out of my 10 yrs + small garden experience are below.
a) Use compost and animal manure such as cow dung (cow pooh!). Your veges grow healthy and spicy too!
b) Need to line the earth filled up area of the container so that soil mass retains moisture in dry weather. Line the container with used polythene.
c) Make sure your pots do not dry up. If this happens, water you apply may not absorb into the soil but drip away from the pot.
d) Spread out some newspaper in the bottom of the container before you fill in the container. Earthworms love this.
e) The latest is better to add a few grains of moisture absorbents into the pot so that moisture is retained for longer periods.
f) My BIG problem is to protect plants from birds which rake the pot to pick up worms!
Happy gardening!
