The Flower Garden

  • Dahlia and Begonia tubers, and Gladioli bulbs, are all in store this month - plant now for a riot of summer colour. Buy online

    • If you haven't completed your rose pruning it is not too late but try to have it done as soon as possible this month. More on Rose pruning (video)
    • It is a good time to plant roses as it gives them time to settle and put on root and leaf growth before spring and summer flowering.
    • Roses are now as popular as ever and are unsurpassed for summer colour and fragrance. There is a rose to suit every situation - groundcover, patio pots, covering walls and trellis, adding colour to the border year after year
  • Now is a good time to prepare ground for sowing new lawns in September. Spray out any perennial weeds with Roundup, dig over and level ground, removing stones, roots, and other debris. More on lawns.
  • Camellias that have finished flowering can be pruned back and fed with Tui Acid Plant Food
  • A protective Copper based spray can be applied to deciduous trees and roses to reduce risk of fungal diseases over spring and summer months. More on sprays. or More on Organice sprays.
  • Good soil preparation is the key this month, prior to spring planting.
  • Dig soil over well, breaking down any clods.
  • Add in lots of good organic compost.
  • A dressing of lime can also be added now, especially in vegetable gardens. This gives the lime time to react before adding other fertilisers in the spring.
  • Remember not to apply lime around plants which like 'acid' soil conditions - Camellias, Azaleas, Rhododendrons, Ericas." 

The Edible Garden

  • Dig soil over and apply generous quantities of good organic compost.
  • Now is a good time to apply garden lime - refer to packaging for application rates

  • Seed potatoes can be planted this month
    • Potatoes grow best in a warm sunny position
    • They prefer a free draining soil with lots of organic matter
    • Make sure seed potatoes have a lot of good sprouts before planting
