Uses for Compost
There are many uses for compost and it is a versatile and rich
product that you can easily make at home.
Applying to Soil
Compost should be applied to your soil in the spring and summer
so your plants will get the benefit of the nutrients during the
growing season.
Roughly, use one wheelbarrow full of compost per five square
metres. This should supply enough nutrients for one
season.
Compost can be either dug into the top 15-20 cms of soil (no
deeper) or left on the surface to act as a mulch (make sure the
soil is moist before doing this). It can be spread over soil
surrounding established plants.
For use with shrubs:
For most shrubs a mulch of compost applied every three years is
sufficient, however, roses and other shrubs that are pruned hard
each year, a more regular feed of compost may be
required.
For use with bedding plants:
If the soil is already in good condition, adding compost to the
soil is unnecessary as too many nutrients can encourage leafy
growth in bedding plants, at the expense of flowers.
For use on lawns:
Sifted compost can be applied thinly as a top dressing to lawns
in spring or summer.
For use in tubs and planters:
A layer of compost can added to the surface of pots and tubs in
the spring.
For use in the vegetable patch:
As vegetables like a rich soil, it is important to add compost
to your vegetable garden every year. This will add the
necessary nutrients to the soil and help to improve the soil
structure.
For use on fruit plants:
For blackcurrants and raspberries, mulch with compost every
three years. For other fruit bushes and trees, mulch with
compost every four to five years. When planting strawberries,
enrich the soil with compost beforehand.
Applying to Herbaceous borders
Mulch with compost every three years.
Using as Potting compost:
As garden compost is so rich, it must be diluted before using it
as a potting compost for raising seedlings. Use one part (by
volume) of compost with one part of loam/good soil and one part
leaf mould or coir.
Making Compost tea:
A compost infusion sprayed onto plants that are being attacked
by pests or diseases can benefit plants and prevent diseases from
spreading.
- Take mature compost, fill a bucket with one part compost to
five parts water.
- Stir, cover and leave to ferment for 10 days.
- Then, strain into another bucket, leave to settle and then
spray the liquid onto affected plants.
This can be repeated after two or three weeks. Crops that
have been treated with compost tea should be washed before
consuming and it should not be used on leafy vegetables that are to
be eaten raw.
