August can be a busy time on the allotment – hopefully there are lots of crops to harvest, such as carrots, runner beans, beetroot, courgettes, and second early potatoes (and possibly maincrops at the end of the month) and soft fruit – blackcurrants, gooseberries and autumn raspberries. You can also harvest onions and shallots – leave them to dry in a sunny spot before storing, and sort out a few good examples to enter into the Pentyrch Horticultural Show on September.
If you have a surplus, think about preserving your crops, or making chutneys and jams.
Keep an eye out for blight on your potato crops – it is spreading through the allotment – you need to cut back the foliage as soon as your crop is affected, and dispose of this by either burning or putting in the green bin – DO NOT add it to your compost.
You can still sow lots of crops in August, for harvests into autumn and beyond, including lettuce, rocket, spring onion, radish and winter salads.
Don’t forget the flower garden – keep dead-heading and staking taller plants. Cut back perennials as they finish flowering, they may put on new growth and re-flower.
A greenhouse is available in Creigiau (approx. 8’x10′) in good condition but without glass – would make an ideal ‘poly tunnel’ type growhouse on the allotment, free to any allotmenteer who is willing to collect – leave a comment if you are interest and I will forward details.
