August garden plant maintenance

August garden plant maintenance in Wokingham and Maidenhead

Berkshire and surrounding areas

August can be a difficult month in the garden for injecting colour into your borders. Some shrubs and herbaceous plants have already flowered and are past their best. Here are a few suggestions you may want to consider planting in your garden to help lift it in August.

The hardy Hibiscus are always worth considering and they love a position in full sun. Try Hibiscus syriacus “Bluebird”; this is the classic Hibiscus with large blue flowers: or try “Woodbridge” with its bright pink blooms, or alternatively “Hamabo” which has large white petals with a crimson blotch at the base. A fantastic little shrub, Perovskia “Blue Spire” commonly known as Russian sage, is a great addition to any border; again it likes full sun and produces large wispy flower spikes of deep blue. This one is best cut back hard in late April to early May as new basal shoots appear. Lycesteria formosa “Gold Wings” is a striking combination of golden foliage with deep crimson pendulous flower spikes, and this shrub too benefits from a hard prune in late April as this will keep it bushy and compact.

Caryopteris are a great genus of shrub; they like full sun and require a hard prune back in late spring when their new foliage starts to shoot. Caryopteris clanodensis “Kew Blue” is one of my favourites – compact with beautiful sprays of dark blue flowers; or try Caryopteris “Worcester Gold” with gold foliage contrasting well with its light blue blooms.

Callicarpa bodinieri “Profusion” is not a widely known shrub but is well worth considering as an addition to your shrub border. It grows up to two metres, produces balls of mauve pink flowers around its stems in August followed by the most incredible violet berries! It also happens to produce a stunning autumn leaf colour as well – what more could you want from a shrub.

Penstemons are a valuable herbaceous perennial for late summer flowers – some varieties: “Hidcote Pink” produces salmon pink flowers with crimson streaks; “Garnet” is one of the most popular cultivars with bold red flowers which have a crimson throat; “Alice Hindley” – pale mauve flowers which keep on coming well into autumn!

In the meantime, enjoy your garden in the sunshine!

Jobs for August

  • Start to take cuttings of any tender plants – should we experience another hard winter they will act as insurance.

  • Rambling roses can be pruned after flowering – thin and shorten shoots and cut out one in three stems at their base, concentrating on the older stems to encourage new stems to grow and replace them.

  • Lightly trim any Lavender to keep it compact

  • Continue to feed tomatoes to help them continue giving a good yield

  • Prune out any wood that has fruited on fan trained cherries or plums

  • Hedges can be given a last cut before winter

  • Wisteria can be pruned now by removing any whippy new shoots to 4 or 5 buds from the main stems
