What to do
Cut back broom when it has finished flowering, shortening the shoots that have flowered to within 5cm/2in of the old wood. Do not cut into this older wood. It will not sprout new growth.
Dead-head lilacs and trim back Clematis montana if it is getting too greedy of space.
Watch for suckers on roses. They always spring from the base of the shrub and the foliage usually looks different to that of the parent. Pull the suckers out if you can, or trace them back underground to their junction with the rootstock and cut them off there.
Cut back the foliage of early flowering Iris unguicularis so that the sun can bake the rhizomes. This will increase flower power early next year. Trim off dead flower spikes of early flowering bearded iris.
Continue to make successional sowings of summer veg. I've been putting in more carrots, including the bright yellow 'Yellowstone' (Suttons £2.35). I've also been sowing more lettuce – the coloured 'Red Iceburg' (Dobies £1.70) and plain-leaved endive 'En Cornet de Bordeaux' (Suffolk Herbs £1).
