May in the garden

May in the garden - Blog Header

May has arrived and the days are getting warmer and longer. Summer is on its way and it’s time to tidy up spring plants, plant out summer flowers and finally start to spend some time out relaxing and enjoying your garden!

 

Here are your main garden jobs this May:

  • Start planting out summer bedding towards the end of this month
  • Prune spring-flowering shrubs after flowering.
  • Trim lavender plants, cutting off old flower heads and about 2.5 cm (1 inch) of the current year’s growth
  • Feed and water container plants.
  • Continue to weed beds and borders to prevent competition for water and nutrients
  • Harvest asparagus spears when they’re no more than 18 cm tall.
  • Thin out direct-sown vegetables such as spinach, carrot and lettuce seedlings, then water the rows well.
  • Pinch out the growing points of broad beans as soon as beans start to appear at the base of the plant to reduce the risk of blackfly attack.
  • Weed around your onions and garlic to reduce competition for nutrients and water.
  • Make supports for your runner beans, using 8 ft (2.4 m) bamboo canes.
  • Harvest rhubarb, picking only one-third of the total amount of stems.
  • Apply lawn weedkiller to your lawn this month.
  • Top up bird baths and bird feeding stations to encourage birds into your garden.
  • Look out for signs of pests and diseases; early prevention is easier than curing an infestation.
  • Clip evergreen hedges now.
