What To Do in the Garden in May

Summer is finally on the way. Warmer daytime temperatures, lighter evenings and clearer skies helps your garden to really come alive with beautiful blooms and bright flowers. May is all about planting and growing, though still be wary of the last remaining pesky UK frosts. Get outside and enjoy your garden as the temperatures get warmer and begin preparing the outdoors for when the summer arrives.

Take a look below at the gardening jobs we recommend you focus on in May:

What To Do in the Garden in May

Plants and Flowers:

Plants and Flowers:

  • Plant out summer bedding plants now to create beautiful displays when the weather gets warmer.
  • As spring bulbs finish, do not cut back the foliage, instead, apply fertiliser around the base which will help you to have even better blooms next year.
  • Plant summer hanging baskets and add a slow-release fertiliser to keep the plants healthy through the growing season.
  • Divide perennials to increase your volume of plants and encourage better blooms and healthier plants.
  • Prune and deadhead plants after flowering to encourage a second bloom as the temperature warms.
  • Tie climbing roses and other flower varieties to support vines as the plant grows.
  • Supplement container plants with a liquid feed every 2-4 weeks to maintain healthy growth and flowering.
  • Plant summer bedding and annuals including Sunflowers and Nasturtium after the last frost.

 

  • Plant perennials as they’ll grow quickly now that the ground is warm. View our handy guide on how to plant perennials.

Lawn Care:

Lawn Care:

  • Apply weed killer to your lawn to prevent and reduce growth before it takes hold. Be sure to apply the correct type to avoid harming your grass growth.
  • Feed your lawn with a nitrogen-rich fertiliser to encourage healthy growth
  • Lower lawn mower blades to their normal summer cutting height as the grass can take a more significant cut now that it is growing regularly.
  • Continue adding lawn seeds and repairing bald patches in the lawn as they develop to create a lush, green space for the summer months.
