How Much Water Do Flowers Need?

Watering plants in the morning allows foliage to dry out during the day.

Flowers need water to grow, but the amount of water depends on the type of flower, how it's planted and the drainage properties of the soil. Check the packaging or plant tags for specifics on your selections.

Types of Flowers

Perennials need less water than annual plants. Water perennials only when planted or in long dry spells once established. Using less water ensures a stronger root system for the plants you wish to return year-after-year. Annuals have a one-season growing cycle with shallow roots and require a more regular watering schedule.

Planting

Container-grown flowers need more regular watering than their bed-grown counterparts as containers will dry out faster than the ground. Water containers-- especially hanging baskets--daily in warm, dry weather. Bed-grown flowers have more room to grow roots in search of water supplies.

Improve Drainage

Improved drainage actually improves the water intake of flowers and other plants. Compost, manure and other organic matter can improve the drainage of your beds. Consult your local cooperative extension office with a soil sample for testing results to improve your drainage. Be sure containers have proper drainage as roots that sit in standing water can suffer from rot and disease.
