This month, there are lots of jobs to do in the garden.

Here are our top four:

Divide your herbaceous perennials. This will keep your plants healthy and vigorous year after year and multiply your stock.

Net ponds now before autumn leaf fall gets underway to reduce the amount of debris entering the water.

Clean out cold frames and greenhouses ahead of autumn sowing and growing.

Plant spring-flowering bulbs now, such as daffodils, crocus and hyacinths, for glorious colour next year.

Here are your main jobs to do in the flower garden in September:

Continue to feed and deadhead hanging basket and container annuals — they will often keep going until the first frosts.

Keep deadheading annuals and perennials to extend their performance.

Deadhead your penstemons, dahlias, and roses to keep flowers coming.

Divide herbaceous perennials as the weather cools. Plant and water in the new divisions well.

Prune any late-summer flowering shrubs, such as the rock rose (Helianthemum).

Prune climbing roses and rambling roses once they’ve finished flowering (unless they are repeat-flowering varieties, in which case leave them until later in the year).

Keep camellias and rhododendrons well watered at this time of year to ensure that next year’s buds develop well.
