12 ways to plug the summer flowering gap

Why is your garden bare, dry and jaded? Here's some tips to perk up your plot in July and August

As much as gardeners tend to love summer (because they can spend all those luscious daylight hours outdoors), the time is approaching when garden beauty starts to dwindle.  Many spaces begin to look barren, with dry soils and parched plants without much in the way of colour. What can you do this month to perk up your plot? water table, dry weather, soil, dry, garden, rain, sunshine, hot, warm, gardening, flowers, plants, barren, bare, flowers, summer, Where's the water this month? It's been so dry and hot that the water table is depleted. The main feature of the moment, weather-wise, is the water table, which is low. The garden naturally tends to look a bit dry and sleepy during a transition period between perennials that flower early and those preparing to flower late. One way to minimise this is to cut back everything before this happens in order to encourage more flowers.  If you do this now you should be rewarded with extra blooms in August. There are wonderful plants, however, that shine during late July and August and it’s well worth putting some in place. Gardeners are very good at planning ahead, and these flowering plants will give you a boost this year and be ready for multiple action thereafter. hardy geraniums, flowers, pruning, july, august, garden, gardening, dry, weather, summer, flowering, perfectplants.co.uk, Hardy geraniums are great perennials that can be encouraged to flower further into the season by trimming back in July.
