Summer Gardening
Tips for gardening in summer:
- Watering: Learn when to water by using your index finger to check soil moisture. Scratch back a little of the surface soil and use your finger to see if soil is moist about 5cm below the surface; if it’s on the dry side, it’s time to water. Learn more here.
- Crop protection: As fruit and veggies develop they may need protection from burrowing insects, fruit fly, birds, possums or bats. Berries, fruit trees and soft fruit like tomatoes are especially at risk. Use insect exclusion netting, bird netting or fruit protection bags to protect crops. Ensure your netting is pegged or tied securely at the bottom to stop pests getting in.
Pests and diseases to look out for in summer:
- Aphids: Small, sap-sucking insects that congregate on the new shoots or the underside of leaves. They can cause leaves to wilt or become discoloured, and also excrete honeydew which can attract ants and other insect pests. To manage aphids, remove them by spraying with a garden hose, apply a soap or alcohol spray, or encourage predatory insects to your garden. Learn more.
- Whitefly: A sap-sucking insect related to aphids, whitefly are found in large numbers on the underside of leaves, and will swarm in clouds when disturbed. Plants may have yellowing leaves or may wilt, and growth will be slowed. Whitefly can be removed with a garden hose or sprayed with soap spray. Badly affected plants should be destroyed. Learn more.
- Fungal diseases: The combination of warm temperatures and summer humidity can form the perfect conditions for fungal diseases to spread. Water plants in the morning at ground level, avoiding wetting foliage wherever possible. Prune off affected foliage, space plants to allow more airflow, and treat fungal outbreaks with homemade or purchased sprays.
