Under Cover - July

Never let your grow-in bags go short of water as you may find it hard to re-wet them thoroughly
Plants in pots may need watering every day, and should be fed once a fortnight with a liquid feed
If whitefly and red spider mite are proving a problem, it is now possible to obtain biological controls, which can be used this month.
Tomatoes should start fruiting this month. Keep the plants well supported and remove side shoots regularly. Use J Arthur Bower's or New Horizon Liquid Tomato Feed every week to ensure a bumper crop.
