Impatiens are some of the most popular annual flowers grown in gardens across North America With their brightly colored blooms and ability to thrive in shady locations, it’s easy to see why they are a favorite for flower beds, borders, container gardens and hanging baskets
But like all plants, impatiens have specific needs when it comes to water. Learning how much water impatiens need and proper watering techniques will ensure your plants stay healthy and filled with flowers all season long.
How Impatiens Grow
Before learning about watering impatiens, it helps to understand a little about how these plants grow. There are hundreds of impatiens species, but most garden impatiens fall into one of three groups:
-
Standard bedding impatiens – These include varieties like Impatiens walleriana, which produce mounded plants 6-24 inches tall with flowers in shades of white, red, pink, purple, orange and more. Standard impatiens thrive in partial shade.
-
New Guinea impatiens – Larger than standard impatiens, these varieties have variegated leaves and produce taller plants reaching 18-30 inches They bloom in similar colors and also prefer partial shade
-
SunPatiens® – A newer hybrid impatiens bred to handle full sun. SunPatiens produce abundant flowers on mounded plants and come in an array of bright colors.
All types of impatiens feature succulent stems and soft, tender foliage. This delicate nature is why consistent moisture is so important for their health.
How Much Water Do Impatiens Need?
Impatiens require moist soil to thrive. Their shallow root systems dry out quickly, and even short periods of drought stress can cause wilting, poor growth and lowered bloom production
As a general rule, established impatiens should be watered about 1 inch per week. This provides enough moisture to keep the soil evenly damp but not saturated.
However, impatiens in containers and new plantings need more frequent watering. Here are some specific guidelines:
-
New transplants – Water thoroughly at planting time, then water daily for the first week while roots establish.
-
Containers – Check soil moisture daily and water whenever the top inch becomes dry. May require watering every 2-3 days in hot weather.
-
Flower beds – Water when top few inches of soil become dry. Established plants need weekly watering on average.
-
Hot, dry weather – Increase frequency to 2-3 times per week during heat waves.
-
Rainy periods – Reduce watering after significant rainfall. Check soil and wait to water until moisture depletes.
How to Tell When Impatiens Need Water
It’s important to check soil moisture and understand visual signs of water stress when growing impatiens:
-
Dry soil – The surface feels dry and crumbly when touched. Dig down an inch or two to check deeper moisture.
-
Wilting – Leaves and stems start to droop when underwatered. Usually the first visible symptom.
-
Slow growth – Poor flowering and small, stunted plants can indicate insufficient water.
-
Leaf yellowing – Lower leaves may turn yellow and drop if very dry.
-
Pale color – Blooms and foliage fade without adequate moisture.
Don’t wait until impatiens show severe wilting or leaf drop before watering. Check soil regularly and water at first signs of dryness.
When to Water Impatiens
Early morning is the best time to water impatiens. This allows foliage to dry out during the day, reducing the risk of fungal diseases. Avoid overhead watering in late afternoon or evening.
For containers and hanging baskets, water until it drains from the bottom to ensure thorough soakings. For in-ground plantings, water the soil deeply around each plant. Try to avoid wetting the foliage when possible. Drip irrigation and soaker hoses work well for impatiens beds.
How to Water Impatiens Properly
Follow these tips for successful impatiens irrigation:
-
Water early in the day so leaves dry before nightfall.
-
Use soaker hoses or drip irrigation to keep foliage dry.
-
Thoroughly soak soil 6-8 inches deep for bed plantings.
-
Allow containers and baskets to drain after watering.
-
Don’t allow soil to completely dry out between waterings.
-
Increase frequency during hot, dry weather.
-
Reduce watering after heavy rains.
-
Check soil moisture 2-3 inches deep to determine needs.
Problems From Over and Under Watering
Consistent soil moisture is key for impatiens. Too much or too little water can cause issues:
Underwatering problems
- Wilting and drought stress
- Leaf yellowing and drop
- Poor flowering and growth
- Stunted, weakened plants
Overwatering problems
- Root rot
- Stem or crown rot
- Fungus and mildew
- Flower and leaf drop
- Decline and death
Allowing impatiens soil to completely dry out frequently encourages spider mites, a common pest. Keep the soil moist, but not saturated, for healthy impatiens.
Creating Moist, Well-Drained Soil
Impatiens thrive when provided moist, humus-rich soil that drains well. Here are some tips for preparing planting beds:
-
Work in 2-3 inches of compost or other organic material when planting.
-
Choose a site with morning sun and afternoon shade to reduce drying.
-
Add mulch after planting to maintain soil moisture and temperature.
-
Grow in raised beds for improved drainage.
-
Consider amending dense clay soils with compost to prevent waterlogging.
With proper soil preparation and attentive watering, keeping impatiens hydrated is easy. A little care will provide non-stop color from these popular shade annuals all season long. Give your impatiens the moisture they require and enjoy the vibrant blossoms they provide in return.
How Often To Water Impatiens
Water Impatiens daily for the first week after planting. Monitor the soil to ensure the water is draining because while Impatiens like damp conditions, they cannot handle standing water. Warm temperatures will cause water to evaporate more quickly, which means Impatiens will dry out, so keep an eye on the temperature and water more often on hot days.
Established Impatiens need water once a week. Plants in sunny locations or drier climates may need water more often. The weather will be a factor, so you may be able to skip a week if there is rain, or you may need to water more often during a heatwave.
Can you overwater Impatiens? Yes, it is possible to overwater Impatiens. Too much water is damaging. It seems counterintuitive, but the plant will essentially suffocate in extremely wet conditions.
Plants grown in containers dry out more quickly, so Impatiens in pots will need water every few days. Although, check on the plants daily if the temperature gets into the high 70s or 80s because the plants may need water more often.
How To Tell If Impatiens Needs Watered
An excellent way to identify when a plant needs water is to feel the soil near the plants base and understand that specific plants needs. Impatiens are thirsty plants, and the soil should never completely dry out. Water Impatiens when the soil feels slightly damp. Wait to water if the soil feels wet. The leaves will wilt or turn yellow if the plant is severely dehydrated.
