September
In The Flower Garden This September
Continue to feed and deadhead hanging basket and container annuals, they will often keep going until the first frosts.
Prune any late-summer flowering shrubs, such as the rock rose (Helianthemum).
Keep deadheading annuals and perennials to extend their performance.
Plant spring-flowering bulbs now, such as daffodils, crocus and hyacinths, for glorious colour next year.
Deadhead your pestemons, dahlias and roses to keep flowers coming.
Keep camellias and rhododendrons well watered at this time of year to ensure that next year’s buds develp well.
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).
Top Tip:
Divide your herbaceous perennials. This will keep your plants healthy and vigorous year after year and multiply your stock. Plant and water in the new divisions well.
