Should You Fertilize Your Garden in July?
Yes.
Many vegetables, including tomatoes, peppers, cucumbers, and squash, are heavy feeders during summer.
However, simply feeding plants may not be enough.
Healthy soil is equally important because it helps:
- Improve nutrient availability
- Support root development
- Increase moisture retention
- Reduce plant stress
Ecoworm Soil Extract functions as both a soil regenerator and fertilizer. Derived from organic vermicompost, it helps support beneficial soil microorganisms while providing nutrients that plants need during the growing season.
One bottle makes up to 53 gallons (200 litres) of ready-to-use fertilizer, making it a practical solution for gardeners looking to improve both soil health and plant growth.
How Often Should You Water Your Garden in July?
Most gardens benefit from deep watering rather than daily shallow watering.
For best results:
- Water early in the morning
- Water deeply
- Apply mulch to reduce evaporation
- Avoid watering during the hottest part of the day
Healthy soils rich in organic matter generally retain moisture more effectively and help plants tolerate heat stress.
