As winter starts to settle into the garden, you might be thinking about putting on your slippers, not your gardening boots. But your garden still needs lots of love during the quieter months, and June is the perfect time for planting roses, citrus, and winter veggies, as well as preventing pesky lawn weeds. And don’t forget your pruning tools – some solid pruning now means you can look forward to beautiful blooms later in the year.

What to plant in the garden in June

Which plants to feed in June

  • Give your annuals and veggies liquid fertiliser, such as Harvest.

Which plants to prune in June

  • Cut back deciduous, ornamental-leafed trees while there are no leaves. If your deciduous tree is a flowering or fruiting variety, however, put down the shears - cutting back now means you'll lose your flowers or fruit for the season. Click here for our ultimate pruning guide.
  • Trim hydrangea stems bearing dead heads and remove old dead wood. Make sure to cut back to the first or second pair of buds to ensure flowers return next season.
  • Cut back your rose stems hard. By removing old wood now, you'll ensure a spectacular spring flower show.

Garden pests, weeds and diseases to look out for in June

June's general lawn and garden care tasks

  • Now’s the time to ward off nasty winter grass. This weed seeds in autumn, winter and spring, then dies off in summer heat. Left untreated, it’ll weaken your lawn and you'll be battling even more winter grass next season. As soon as you discover any growing in your lawn, spray with a selective weed control like Amgrow Chemspray Winter Grass Killer.
  • Are bindiis the bane of your existence in spring and summer? Get them under control now with an application of Bin-Die.
  • Take advantage of the quieter months to service, clean and sharpen your gardening tools and lawn mower.
  • Buy and plant spring flowering perennials. Add a handful of compost, manure or some complete plant food to the soil. This will ensure healthy spring growth.
  • Cut back and divide your perennials. Simply remove the plant from the ground and shake away some of the soil so that the roots are easily seen. The root ball can now be divided by pulling it apart with your hands, a spade or sharp knife. Replant the divisions immediately and keep damp until the new plants are established.
  • Reduce the amount of water you're giving to your indoor plants over winter. Don't forget, most indoor plants are native to tropical climates (where thick canopies block direct sunlight), so bring the water to room temperature before you give them a treat - they're not used to it being icy!
