Seasonal tips
- Mulch heavily around vegetable beds to retain moisture and suppress weeds in this consistently warm climate.
- Practice succession sowing for heat-loving crops like beans or squash to ensure a continuous supply throughout the summer.
- Prune back any leggy okra plants to encourage bushier growth and higher fruit production.
Pest & disease watch
- Monitor for spider mites on Malabar Spinach, which thrive in hot, dry conditions.
- Watch closely for aphids clustering on new Okra shoots.
- Check soil moisture regularly as heavy heat can stress plant roots quickly.
Watering this week
Water deeply and frequently during the day to keep soil consistently moist but avoid wetting the foliage to prevent disease.
Add a nitrogen-rich fertilizer now to boost leafy growth in your Malabar Spinach before the midday sun intensifies.
