●● Sow late-flowering annuals, herbs and vegetables including early carrots, runner beans and parsnips. ●● Continue to harden off summer bedding plants, but if you live in a cold area, don’t plant them out for a few more weeks. ●● Stake and support stems of herbaceous perennials including delphiniums and peonies. ●● Continue to water trees, shrubs and border plants that you have planted this spring. ●● Regularly spike over border soil with a fork to relieve compaction and remove weeds. ●● Give acid-loving plants such as rhododendrons, azaleas and pieris a feed with a fertiliser formulated for them, to prevent leaves turning yellow. ●● Spread a layer of well-rotted compost around perennials. ●● Finish planting out sweet peas and tie in new growth. ●● Sprinkle the base of all roses with a generous handful of rose fertiliser.
