A word about controlling weevil grubs
this week: As summer progresses our gardens can become overgrown and untidy. Kathy Vivian suggests some jobs to keep it looking good
VINE weevils are common pests in the garden. If the leaves of your container plants have nibbled edges, it may be adult vine weevils causing the problem. However, it’s the vine weevil grubs that cause the most damage and can actually kill plants. They are hidden in the soil and can cause serious damage by eating plant roots. The grubs are active in August, so if you have problems with vine weevil, now is the time to treat affected containers with a biological control. Nematodes are availably that can be mixed with water and applied to the compost.
AugustAug is the last chance to prune hedges this season. This is particularlypar important for ev evergreens, as they can die-backd if cut later in the year.
Trim back any perennials thatth have flopped over. They willw produce new growth and maym even flower again.
Trim off lavender flower spikes after flowering to keep plants compact. Cut about 2.5 cm (1 inch) into the new growth, but don’t cut down to the old wood.
Remove dead flowers and leaves from bedding plants to keep them looking fresh and to encourage more blooms.
The recent rain has led to more weed growth. Try to pull out the weeds before they set seeds and spread around your garden.
Feed flowering and fruiting plants with a high-potassium fertilizer to encourage the plants to keep producing buds. Liquid tomato feed is ideal for this. This type of fertilizer is also good for woody shrubs and trees in containers as it helps to produce tougher growth that survives the winter better.
Give lawns a high phosphate fertilizer in August as it promotes strong root growth.
Autumn bulbs, such as autumn crocus (Colchicum) and Nerine can be planted now.
