Rose tasks for August
• Finish pruning the roses by 8 August, except in very cold areas when• Tidy up climbing roses. Untie the canes and remove any old growth, keeping the strong, newer canes as the framework. Tie up and cut back side stems by 10 – 20cm.• Check the stakes of standard roses and make sure the top of the stake is in the middle of the rose crown so that it can be firmly tied, with soft ties, to the stake.• Wait until the soil warms up towards the end of August before adding new mulch around the roses.• Increase watering to twice a week, fertilise with Vigorosa (if you didn’t fertilise in July) and check the tips of new growth for aphids. Wash them off with a strong jet of water, spray with Ludwig’s Insect Spray or drench with Koinor, which will also control thrips.
