Summer can be a tough season for your garden on Our 200 Acre Farm. While growth is abundant, the heat, pests, and sudden storms can challenge even the healthiest plants. Here’s how to troubleshoot common summer issues so your garden continues to thrive through the hottest months.
1️⃣ Managing Heat Stress
Wilting leaves during the heat of the day are normal, but if leaves remain wilted in the morning, your plants need help:
✅ Water deeply in the early morning, allowing moisture to reach deeper roots.
✅ Mulch heavily to keep soil cool and reduce evaporation.
✅ Provide temporary shade using shade cloth or old sheets during extreme heatwaves to protect vulnerable plants like lettuces, cucumbers, and young seedlings.
2️⃣ Blossom End Rot in Tomatoes and Zucchini
Blossom end rot (black sunken spots) often appears in tomatoes and zucchinis during summer due to uneven watering and calcium uptake issues.
✅ Maintain consistent watering—deep and regular rather than shallow, infrequent watering.
✅ Add compost to improve soil structure and calcium availability.
✅ Avoid heavy feeding with high-nitrogen fertilisers, which can affect calcium uptake.
3️⃣ Dealing with Pests
Warm weather brings out pests like aphids, whiteflies, and cabbage moth caterpillars:
✅ Encourage beneficial insects (ladybirds, lacewings) by planting flowering herbs like dill and coriander nearby.
✅ Use soap sprays (mild dish soap diluted in water) for aphids and whiteflies if infestations are heavy.
✅ Handpick caterpillars early in the morning, or use fine netting over brassicas to prevent egg laying.
4️⃣ Powdery Mildew on Cucurbits
Powdery mildew often appears as a white coating on leaves of pumpkins, zucchinis, and cucumbers in humid, warm weather.
✅ Water at the base of plants, not on the leaves.
✅ Improve airflow by spacing plants adequately and removing excess foliage.
✅ Use a homemade spray of 1 part milk to 9 parts water applied weekly to slow its spread.
5️⃣ Heavy Rain and Storm Damage
Sudden summer storms can flatten plants and cause waterlogging:
✅ Stake or cage tall plants like tomatoes to prevent breakage.
✅ Improve drainage where possible, raising beds if your area is prone to flooding.
✅ After heavy rain, check for compacted soil and gently aerate around plants if needed.
Stay Observant and Flexible
Daily or every-other-day checks in summer help you catch problems early before they escalate. Maintaining your mulch, watering deeply, encouraging beneficial insects, and taking quick action will keep your garden productive and resilient through summer’s challenges.
Summer gardening isn’t without its hurdles, but with these practical steps, your garden can continue to provide fresh, nourishing food while staying healthy during the hottest part of the year.
