Hedging Plants in Containers (VI)

Hedging Plants in Containers obviously require compost – but which sort? Here are a few tips…
• Don’t use earth from the garden unless you have perfect, weed-free friable soil – and even if you have, you might be importing unwelcome insects or even disease whose adverse effects will be magnified in a confined space
• There are three layers to add. From the bottom up:
Bottom: Gravel, crocks, pebbles etc for drainage
Middle: A layer of mulch or garden compost
Top: The main compost (see below)
• MAIN COMPOST: John Innes No. 3 or similar is a good starting point. To aid drainage and aeration, mix in some organic material like bark or inorganic material like grit.
There are two schools of thought concerning perlite – some say add it because it helps good drainage, others say don’t bother because it will eventually float to the top! Perhaps the point is that perlite will not have any detrimental effect
• FERTILISER: Because proprietary composts contain feed for six – eight weeks, there is no need to add any fertiliser at planting. However, you can mix in some slow-release granules at the start. It will save you a job later. However, fertilisers tend to encourage foliage, rather than root, growth so go easy at the start – the first thing Hedging Plants in Containers need is strong roots
