Water your plants early in the morning or late in the evening to minimize evaporation.
This depends on the type of plant, soil, and climate. In general, watering deeply but less frequently promotes strong root growth.
Check the soil moisture level before watering. Overwatering can lead to root rot and other diseases.
Use a watering can or hose with a gentle spray to avoid damaging the plant. A soaker hose or drip irrigation system can be more efficient for larger gardens.
Water the base of the plant where the roots are, not the foliage. Wet leaves can promote the spread of disease.
Applying mulch can help retain soil moisture and reduce the need for frequent watering.
Plants usually need more water in the hotter, drier summer months and less in cooler, rainy periods.
