Gardening In June

June is a great month to enjoy working in the garden. Flowers are in bloom and the borders will be looking their best. Also a month to harvest early fruits.

To maintain your garden so that you can enjoy it longer, carry out the following tasks. .

Garden general

  • Regularly remove weeds but continue to take that extra bit of care in doing so. The seedlings from last year are already coming up, so keep checking before you pull.
  • If you are using selective weed killers against persistent weeds, cover neighbouring plants before you use them or place a sheet of plastic with a slit over the weeds (or over-proliferating plants like bamboo) to avoid killing them too. Limit the use of these products as much as possible!
  • Keep weeds and moss clear from garden paths and patios.
  • Give young trees, half-standard shrubs and standard roses a sturdy support stake and check the ties regularly.
  • Place place supports between tall growing perennials before they grow too big.
  • Remove overblown flowers and seed boxes from ornamental flowering shrubs like rhododendron. This stimulates the development of new shoots.
  • Ensure abundant flowers on your Wisteria next season by removing the overblown flowers and seed pods. If you like the decorative pods and you don't mind fewer flowers next season you can of course leave them on the shrub. However, please be aware that if children have access to your garden, all pods must be removed. They are highly poisonous!
  • Check your plants for snails and slugs at least once a week, but preferably daily. Young leaves in particular are very appetizing to them. Delphiniums, young seedlings, or a Hosta that is just poking its fresh young leaves above the ground can be devoured in one night.
  • Fertilise your plant borders with manure.
  • Ornamental shrubs need some manure too, and hedge plants need even higher doses. They stand closer together and therefore have to compete for nutrients.
  • Leave spring-flowering bulbs, like Tulips and Hyacints, undisturbed until the foliage has died back. Naturalising bulbs, like Spanish squill, Muscari, Crocus and Narcissi can similarly be left in the ground. Don't remove any foliage until it drops off.
  • Spring bulbs that have been taken up can now be dried and stored in a sheltered place. Shake off excess soil and place them somewhere dry and dark.
  • Roses are in full flower by now. Check for lice and other pests or diseases every day. Take action at the first sign of trouble.
  • Remove spent flower heads from Roses and perennials.
  • In warm, dry spells water the borders and other plants once a week for a few hours. This is much more effective than 15 minutes every day.
