With June comes the longest day of the year, and the extra light and warmth encourages the garden to put on an exuberant burst of growth. So, what sort of gardening jobs should we be doing, to keep on top of things? We asked our gardening team to share their top tips…


  1. Lawn maintenance - Mowing and edging regularly will set off your borders brilliantly and make the garden look well maintained even if there are a few weeds in the beds! Mowing should be done at least once a week at this time of year.
  2. Dead heading - Dead heading those plants which will flower for longer if the old flowers are removed (e.g. some roses, bedding plants).
  3. Weeding - It is important to take out weeds before they flower and send seeds around the garden. Hoe borders regularly to keep them down.
  4. Cutting back – Cut back hardy geraniums, alchemilla and delphiniums to ground level when they finish flowering, then new fresh leaf cover will grow and (hopefully!) new flowers will appear later in the year.
  5. Plant supports - In early June (if you missed it in May) get your plants supports in before the plants flop over and make the job twice as difficult. Cut at least a third off sedums and some other late flowering perennials as this makes them bushier and less likely to flop open before the flowers appear.
  6. Summer bedding - June is ideal for planting out your tender perennials and bedding plants, but make sure you have watered the plants before and after you plant them, to give them the best possible chance.
  7. Move plants outside – With the risk of frost gone, now is the best time to place tender plants such as agapanthus and citrus plants outside.
  8. Fruit thinning - It’s good to fruit thin for a number of reasons, instead of getting a large quantity of smaller fruit you’ll get a fair amount of good sized fruit. Thinning also helps keep the fruit healthy and stops the tree from becoming depleted, so it’s less susceptible to pests and disease. Fruiting on trees tends to follow a four year cycle of heavy cropping, followed by a very poor year (as the tree recovers), the next 2 years the size of the crop increases until it hits the ‘bumper’ year again, by fruit thinning you’re managing this cycle, eliminating the extremes, to ensure there’s a reasonable crop each year.
  9. Cut your box hedging - Avoid cutting during very hot and sunny weather due to these plants being susceptible to sun scorch. When doing this at home you can avoid this sun scorch by spraying the foliage with water before cutting, but being aware that this should not be done when using electric hedge cutters due to the risk of electrocution!
  10. Don’t forget your veg plot - Pinch out sideshoots on tomatoes and harvest lettuce, radish, other salads and early potatoes. Enjoy the fruits of your labour.
