Tips for Maintaining a Heat-Tolerant Garden
-
Mulching: Use mulch to retain moisture and keep the soil cool. Organic mulches like bark, straw, or compost work well.
-
Watering: Water deeply but infrequently to encourage deep root growth. Early morning or late evening watering is best to minimize evaporation.
-
Soil Preparation: Ensure your soil is well-drained. Amend with compost or sand if necessary to improve drainage.
-
Shade and Shelter: Provide some shade for sensitive plants during the hottest part of the day. Use shade cloths or strategically plant taller plants to create natural shade.
-
Fertilizing: Use a slow-release fertilizer to provide nutrients over time. Avoid over-fertilizing, as this can stress plants in hot conditions.
-
Pruning: Regular pruning helps maintain plant health and encourages new growth. Remove any dead or damaged parts to prevent disease.
