Mildew may also be a problem. It has already broken out on my acanthus. The answer is to spray roses and herbaceous plants, where necessary, with fungicide.
There is still time to fill gaps in borders with fast growing annuals such as clarkia and cornflower. If you have had no luck in the past with sowing direct in the ground, try scattering the seed thinly over compost in a seed tray, and waiting for the seedlings to grow in that. Do not bother to prick them out. Just transplant them in little clumps to the places you want them to grow.
Biennials such as double daisies, forget-me-nots, wallflowers and sweet williams should be sown in well-soaked drills outside, ready for a display in spring and summer next year.
I am also sowing seed of a Shasta daisy called 'Snow Lady' (Mr Fothergill, pounds 1.79) which is less than 1ft tall. They are surprisingly successful in difficult areas where there is little sun.
Take cuttings of pinks, pulling off non-flowering side shoots and pushing them round the edge of a 5in pot of compost mixed with extra sand. Cover the pot with a polythene bag until the cuttings have rooted.Reuse content
