Many garden plants and vegetables are suitable for growing on or
around compost heaps. One absolute favourite of GardenAction is
Nasturtium. These plants have great leaves and will still
produce loads of flowers when grown on a compost heap. They are
really climbers but they scramble over a compost heap at an
amazing rate. They are also very cheap and almost indestructible.
Your compost heap is moist and very fertile so vegetables such as
cucumbers, cabbage and potatoes will love this environment - as
long as it gets enough sun.
One other trick with compost heaps is to grow plants such as
hollyhocks, sunflowers or dahlias (dahlias love this) in largish
pots and put the plants in the pot into the compost heap. The
plant roots soon spread out from the bottom of the pot and feed
on the compost heap nutrients.
Planting In Your Compost Heap
Compost heaps shrink as they decompose, so only plant at least two
months after adding the last load of waste.
When planting, use only well rooted plants, and surround the plant
with a good few handfuls of potting compost to keep them in
place. Don't bother trying to grow from seed - the environment
on top of a compost heap will give you very little chance of success.
Planting Around Your Compost Heap
The soil for a metre (3 ft) around your compost heap will be
full of nutrients, so try planting dahlias, hollyhocks or
chrysanthemums where they can get some sun. Rhubarb likes lots
of nutrients, so it will also do well here.
