What should you do in your garden in June? At  M O Sullivan Garden and Tree Services,  we decided to share some of the gardening activities that can be done in June. We have performed most of the following suggestions in various gardens in such places as Foxrock, Crumlin, Walkinstown, and many other Dublin areas since the start of June.  These are most of the tasks you should perform in your garden to ensure its health and productivity:

Fruit and Vegetables

  1. Plant out sweetcorn: Arrange plants in blocks to aid pollination.
  2. Cover developing and ripening fruits: Use netting or fleece to protect them from birds.
  3. Enjoy last asparagus harvests: Leave the ferny top-growth to grow over the summer.
  4. Spread mulch around thirsty crops: Hold in moisture around the roots of beans and courgettes.
  5. Check for woolly aphids: Treat infestations on fruit trees with soap-based spray.
  6. Water vegetables and fruit in containers: Regularly water during dry sunny weather.
  7. Go on regular snail hunts: Reduce populations, especially on damp evenings.
  8. Tie in new shoots of blackberries, raspberries, and other cane fruits: Encourage more growth
  9. Apply tomato feed regularly: Feed fruiting veg crops like tomatoes, courgettes, pumpkins, and chilies.
  10. Plant up an edible hanging basket: Use trailing tomatoes and herbs, and keep it well watered.
  11. Rejuvenate chives: Cut the clump down to the base for a fresh crop of new leaves.
  12. Water beans and peas: Water as they start to flower.
  13. Pull out any raspberry canes: Remove those sprouting out of their dedicated area.
  14. Take softwood cuttings of herbs: Plant in gritty compost and place on a sunny windowsill.


  1. Lift and store tulip bulbs: After flowering!
  2. Give wisteria its summer prune: Cut long side shoots back to 20cm to promote flowering next spring.
  3. Plant up a new tropical display: Use tender exotics like bananas, Ricinus, coleus, cannas, and amaranthus.
  4. Support tall-growing perennials: Use sturdy canes for hollyhocks and delphiniums.
  5. Continue planting summer bedding: Water regularly to help plants establish quickly.
  6. Cut back spring-flowering perennials: Encourage a fresh flush of foliage.
  7. Tie in new stems of climbing and rambling roses: Horizontally to supports to encourage more flowers.
  8. Take cuttings from pinks and carnations: Select non-flowering shoots, which should root readily.
  9. Pinch out the tips of fuchsias and bedding plants: Encourage bushier growth.
  10. Give container displays and hanging baskets a liquid feed: Every few weeks to encourage flowering
  11. Fill gaps in borders with pots of tall bulbs: Add instant color with fragrant lilies.
  12. Prune late-spring or early-summer shrubs: Thin out older stems after flowering.
  13. Add marginal plants: Around the edges of your pond with arum lilies and marsh marigolds.


  1. Sow herbs in pots: Grow on your kitchen windowsill with coriander, parsley, and basil.
  2. Plant out tender vegetables: Raised indoors, including beans, tomatoes, pumpkins, courgettes, and sweetcorn.
  3. Pinch outside shoots of cordon tomatoes: Regularly to encourage fruiting.
  4. Harden off hanging baskets and pots: That have been growing in the greenhouse.
  5. Sow biennials: In seed trays, including foxgloves, honesty, wallflowers, and sweet rocket
  6. Water plants daily: In warm weather, ideally in the evening or early morning, and avoid splashing the foliage.
  7. Introduce biological controls: To the greenhouse if you have pests like whitefly or red spider mites.
  8. Take softwood cuttings from hydrangeas and pelargoniums: Stand the pots on a bright windowsill or in a greenhouse.
  9. Increase greenhouse shading and ventilation: Keep temperatures down on hot days.
  10. Feed flowering and fruiting plants: Weekly with tomato feed.
  11. Water greenhouse tomatoes: Regularly to prevent split fruits and blossom end rot.
  12. Treat pots with vine weevil control: If this pest has been a problem in the past, as larvae become active this month.

House Plants

  1. Start feeding houseplants: Once a week with liquid fertiliser, continuing through to autumn.
  2. Water your houseplants: More regularly.

Lawn and Maintenance

  1. Mow the lawn: At least once a week and trim the edges
  2. Water the lawn: In the morning or evening to minimize evaporation.
  3. Keep an eye on weather reports: Adjust watering schedules accordingly.
  4. Check for pests and diseases: Regularly inspect plants for signs of infestation or infection
  5. Remove suckers from tomato plants: To promote healthy growth.
  6. Prune shrubs that bloom on old wood: After they are done flowering
  7. Be on high alert for insect pests and diseases: Monitor for aphids, asparagus beetles, cabbage worms, cutworms, tomato hornworms, scale, snails, slugs, leaf spots, mildew, and rust.


  1. Remove blanket weed: To help both fish and plants breathe
  2. Leave removed foliage overnight: Give any caught animals and insects a chance to return to the water

Autumn Planting

  1. Sow autumn plants: Such as pansies and polyanthus in a tray of fine compost, water, and cover lightly

These tasks will help ensure your garden remains healthy and productive throughout the summer months.
