Flowers & shrubs

Leave any spring bulb foliage to die back naturally before you cut back. Once their leaves are yellowing you can lift and divide snowdrops and bluebells. Lift tulip bulbs and store them somewhere dry, cool and dark ready to plant out again later in the year.

Prune flowering shrubs.

Harden off half-hardy bedding plants ready for planting out.

Herbaceous plants are best planted in the early autumn – but we have good stocks now, and they are a brilliant way to fill any gaps in your borders. Never sniff at instant colour!

Pick sweet peas frequently to encourage more flowers. These make really sweet flower displays in the home.

Staking taller plants will help them from being damaged by strong winds or summer storms.

Use straw to protect strawberry plants. This helps with weed control and keeps the berries off the ground. Garden birds will be interested in your fruit crops, so invest in garden netting to deter them!

In your edible patch

Whether you’ve got an allotment or a small area of your garden where you grow, you can really start to enjoy your home grown veg now.

Lettuce, radish and other salad crops are ready to pick. It’s a good idea to plant more salad every couple of weeks so you have lots of fresh supplies over the summer.

Spud-u-like! You should be able to start harvesting first earlies now. For second earlies and main crop, keep earthing up the plants to encourage a better crop.

If you are growing potatoes in containers, keep the compost moist – but don’t overdo it. If the potatoes get too wet you may actually stunt growth rather than help it.

Make sure you’ve netted your soft fruit otherwise the birds will be having more of a feast than you.

You can safely harden off your greenhouse-grown vegetables and plant these outside now.

Tomatoes should be growing well now. Pinch out sideshoots as this will strengthen the plant’s growth and stop it becoming leggy. Don’t apply feed until you see the first fruit set.

Containers

Harden off containers that you’ve kept in the greenhouse to protect from late frosts and put them out on display.

Similarly, summer hanging baskets can be hung if you haven’t done this already. Remember to keep on top of plants that grow leggy, prune them back and you’ll get bushier plants for a longer flowering season.

Start watering containers and baskets regularly.

General tips

  • Don’t forget to deadhead, the sooner you get into a routine, the longer your flowering season will be.
  • The bugs will start to proliferate with the warmer weather unfortunately, so keep an eye out for lily beetles and vine weevils.
  • Weeds also love warmth and if left to grow in borders they’ll take precious light, nutrients and water from the plants you do want. Bindweed is springing into action already.
  • You can get rid of bindweed if you are persistent in digging out as much of the root as you can, then as soon as it starts to grow again, dig it out again – eventually the plant will weaken, although it may well return next spring.
  • While ‘no mow May’ is over, you still might like to leave a part of your lawn unmown. Then you can allow weeds to grow naturally – they provide food and shelter for wildlife and actually look really pretty in a wilder area of your garden.
  • For cut lawns when there’s a spell of dry weather keep the mower blades higher. Use lawn fertilizer to keep the grass healthy.

June is a lovely month to start enjoying really enjoying the outdoors and especially the garden. Invest in some comfy garden furniture, pop up the parasol and start dining alfresco – although you may still need a blanket for later evenings. Add a jug of sweet peas on the table for instant decoration and a lovely fragrance!
