Summer garden care starts with smart, sustainable actions that keep your plants, soil and lawn healthy, even during the hottest months of the year. When temperatures soar and rainfall becomes unpredictable, it’s important to protect your garden from heat stress and moisture loss. These simple but effective tips will help you nurture a resilient, water-wise landscape that looks lush and vibrant all summer long.”
1. Mulching for smart summer garden care
Mulching your garden is critical during summer. It will suppress weeds, retain soil moisture, slow and prevent soil erosion and protect plant roots from temperature extremes. Choose a mulch, such as Rocky Point Sugar Cane, Premium Jumbo Bark Nuggets, Tea Tree or Lucerne mulch. We have a wide range of mulches to help protect your garden this summer while giving it a feed as organic mulches also feeds the soil as they break down, improving soil structure and boosting beneficial microbial activity
2. Keep the fertiliser up
Summer plant growth requires regular nutrition for best results. This growing season use Rocky Point’s ActivGrow Fertiliser pellets or Poultry Manure pellets for an abundance of fresh fruit and vegetables and vibrant blooms. Feeding little and often will keep your plants strong and able to withstand hot, dry spells. Remember to water deeply after fertilising to help nutrients reach the root zone effectively.
3. Flowers to plant now for a boost
Zinnia, Cosmos, Petunia, Torenia, Alyssum, Dianthus, Aster, Vinca, Dahlia, Coreopsis, Gomphrena, Marigolds, Salvia and Verbena all perform well in summer.
Tip: Plant in groups, dead-head regularly and mulch to reduce watering requirements.
4. Pest watch in your summer garden care routine
Keep an eye out for pest population explosions such as grasshoppers, caterpillars and other sap-sucking insects that thrive on all that new lush summer growth. Always choose organic options for control so that no harm comes to pollinators and beneficial insects. Encourage natural predators like ladybirds and birds by maintaining a diverse garden habitat with flowering plants and native shrubs.
5. Hedges and lawn care
Hedges: For dense healthy screening, lightly prune and fertilise little but often during the growing season. Make sure you water deeply during hot spells and keep the root zone mulched.
Lawn Care: Keep an eye out for lawn grub attacks and use a certified organic option for control to prevent harming birdlife that may feed on dying grubs. Mow higher in the heat, water deeply and less often and consider a summer application of Rocky Point Hose-On Lawn Food or Wetting Agent.
6. Fruit crop protection for summer garden care
In subtropical and tropical climates, hang fruit fly traps and bag soft-skinned fruit with exclusion bags to protect them from the Queensland Fruit Fly and Fruit Piercing Moth. Harvest promptly and remove fallen fruit to break the cycle. Regularly checking fruit trees ensures you can act quickly before pests take hold.
7. Indoor plants & tropicals: extend your summer garden care
Indoor Plants: Keep your indoor plants’ leaves clean, healthy and pest-free with Rocky Point’s Plant Foliage Spray and Indoor Plant Tonic. Rotate plants so they receive even light and check your watering—many gardeners over-water in summer.
Tropicals: Now’s the time to check out your local garden centre for beauties such as flowering gingers, heliconias, caladiums and other tropical delights like bat plants and hoyas. Give them warmth, bright light and a free-draining mix like Rocky Point CocoPro Potting Mix.
Christmas Tree Care: If you bought a living Christmas tree, once Christmas is done move it outside to a semi-shaded position and water well with some liquid seaweed. Acclimatise gradually by gradually increasing its sun exposure over 4–6 weeks.
