Asters are easy fall plants that bloom in fall and have low watering needs. These plant develop drought tolerance once established and can suffer in wet or soggy soils. Overly wet areas can cause the roots to rot and kill the plant. However, in their first year and during periods of drought, they should be watered well at least once a week. They have a shallow root system, and a light application of mulch or compost will help to maintain moisture during dry periods.
How To Tell If Asters Needs Water
Asters show signs of needing water by exhibiting dry or yellow leaves, starting from the bottom of the stem upwards. Drooping leaves or flower heads are also a sign of lack of water.
How Often To Water Asters
Water newly planted asters at least once a week until well established and more frequently in dry weather. They are drought tolerant once established and will only need water during prolonged dry periods. Asters do not like boggy soil and may rot in standing water.
Asters growing in pots or containers in full sun will need to be watered more frequently, at least every other day depending on the pot size and weather conditions. Feel the soil and water when the top two inches are dry to the touch.
Best Time To Water Asters
Asters are best watered in the morning so that any moisture on the foliage will be evaporated by the sun. They should be watered at the base; avoid getting the foliage wet as this may promote mildew.
How to Water Asters
Step 1 - Water in the morning
Step 2 - Water at the base of the plant, and avoid getting the foliage wet
Step 3 - Apply water slowly, so it can seep into the soil and hydrate the entire root zone
Step 4 - Water more frequently in dry weather
Aster Watering Tips
- Water at least once a week to help plants establish
- Water well in dry weather, providing deep soaks to encourage deep root growth
- Apply water to the root zone and avoid wetting the foliage
- Water asters in pots at least every other day
