Pots and borders
Remove dead flowers from tall perennials such as delphiniums
. This will encourage them to flower again this year.
Fill any gaps in your borders and pots with plants that provide instant colour. Pot grown lilies
and marguerite daisies are all suitable gap fillers and great late summer performers.
Some perennials such as Lady’s Mantle Alchemilla mollis
can be too successful and may seed themselves everywhere. To limit their spread, remove the flowers as soon as they fade so that seeds cannot form.
Trees, shrubs and other perennials
All lime-hating plants, either in pots or in the garden, will reward you next spring if you regularly feed them now. Use a specific plant food such as Miracle-Gro Azalea, Camellia & Rhododendron feed. This month is when next year’s flower buds form, so ensure they don’t go short of food and water.
Check susceptible varieties of plants for vine weevil damage. Half circle notches out of the edges of leaves are common at this time of year and are caused by the nocturnal adults. Likely plants to show symptoms are Viburnum
. If any damage is present, treat with natural nematode predators - water them around the roots where the grubs cause the greatest damage.

blooms as they fade. Most will grow new small flowers further down the stem. Leave a few to produce seeds for the birds in winter.
and hardy geraniums
back hard when they get scruffy. Within a very short time, they will produce new fresh-looking leaves and perhaps some flowers too.
Lawns and flower meadows
- If you have the odd weed or two in the lawn - who hasn’t - spot weeding with Weedol selective Lawn Weed Killer now can be very effective. Alternatively apply Aftercut All in one Feed, Weed and Mosskiller.
Ponds and wildlife
Check the water level in ponds and water features regularly. A lot of water can be lost through evaporation. Top up if necessary.
Thin out oxygenating weeds so that they occupy around a third of the water volume.
Look out for dragonflies and damselflies this month. Your pond should be full of life at this time of the year.
