What to do this month




By Harmony Garden Centre

Let's get growing 

 The busy time of Christmas and New Year is now a memory and summer is well and truly with us. Summer is a time to relax and to enjoy the rewards of life. Enjoying a cool drink in the shade of a cool patio or shady tree is an important part of summer gardening - although there is still plenty to achieve during the cooler parts of the days




We all need lots of water over the summer and our plants are no different. Regular deep soaking of garden beds every few days is much better than light and shallow daily watering. Outdoor potted plants, hanging baskets and the veggie garden will need a watering each day during the cooler morning or evening. Check that watering systems are operating correctly and using a water retention granule or gel will help to minimise water use and keep your plants happy 


  • Job List

  • Treat garden with a plant and soil conditioner such as Seasol. This will help your garden cope with extreme summer conditions
  • Applying water retention granules such as Saturaid to your soil or lawn can reduce water use by up to 50%. This can be a great way to save on the water bill and make efficient use of the natural resource of summer rains.
  • Water Smart! It’s best to water first thing in the morning, to give your soil a chance to absorb the moisture before it gets too hot.
  • Top up your gardens with mulch, it looks great and helps with water retention.
  • Now is the time to plant french and climbing beans, broccoli, brussel sprouts, cabbage, chinese cabbage, capsicum, cauliflower, celery, cress, cucumber, eggplant (advanced seedlings best), leek, lettuce, spring onion, parsley, parsnip, pumpkin, radish, swede, silverbeet, turnip & sweet corn.
  • If your earlier plantings of dearly loved tomatoes are starting to show the fruits of your labour, now is the time to get cracking with a fertiliser enriched with potassium sulphate to ensure plentiful crops.
  • Crops such as sweetcorn and tomatoes are likely to be looking top heavy, so make sure you have adequate support for your plants. Add a layer much such as pea straw or sugar cane mulch to maintain ideal growth conditions.
  • Raise mower blades and avoid scalping your lawn. Scalping your lawn will encourage weeds to take hold and reduce the foliage protection to the nearby soil. Short grass effectively results in shallow lawn roots and grass with poor disease resistance.
  • Spray roses to control black spot and pick up fallen leaves around your roses.
  • Watch out for unwanted pests such as aphids. Ask about the best methods of control.
  • Prune spent flowers on your roses, rhododendron and camellia.
  • Roses will benefit from an application of 'Sudden Impact' rose fertiliser for a wonderful autumn rose display (in 6-8 weeks time) which will not only ensure more flowers but reward you with healthy plants.
  • Spray apples, pears and hawthorns with Yates Success to control pear and cherry slug. If you don't want to spray, dust with dolomite lime or wood ash, or remove by hand.
  • Control passionfruit leaf hopper with Yates Mavrik insecticide
  • Harvest beans and other summer veggies regularly so they’ll produce more crops.
  • Cut back and feed annual flowers.
