Watering newly planted plants can vary depending on soil type, temperature and type of plant. In general, water initially when planted with several gallons of water. After initial watering, water every two to three days if temperatures are under seventy-five degrees. If it's over seventy-five degrees, water daily for one week. Be sure to keep an eye on the plants daily.

The best way to determine if a plant needs water is to stick your finger into the soil two to three inches. If it feels moist, you should not need to water, but if it feels dry, water the plant. Hanging baskets should be watered daily and fertilized weekly with a water soluble fertilizer like Miracle Grow. This holds true for tropicals as well.
