Tips for Growing Impatiens in Sunny Locations

If you want to grow sun-tolerant impatiens in your garden, patio or balcony, here are some tips to ensure they thrive:

Provide adequate moisture and avoid letting the soil dry out

Sun-loving impatiens have higher moisture needs than those grown in the shade. Water your plants regularly, and make sure the soil stays consistently moist. Avoid letting the soil dry out completely as this will stress the plants and may lead to wilting.

Make sure the plants receive some shade during the hottest parts of the day

Although sun-tolerant impatiens can handle more sun than traditional impatiens, they still need some shade during the hottest parts of the day. Provide natural or artificial shade to prevent the plants from getting too much direct sunlight.

Provide regular fertilizer, as sun-tolerant impatiens have higher nutrient needs than those grown in shade

Sun-loving impatiens require regular fertilizer to maintain their vibrant flowers and healthy growth. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply fertilizer every two weeks during the growing season.

Mulch the soil around the plants to help maintain moisture levels and regulate temperature

Adding a layer of mulch around your sun-tolerant impatiens can help maintain moisture levels in the soil and keep the roots cool. Choose an organic mulch such as shredded leaves, grass clippings, or straw.

How to Care for Sun-Tolerant Impatiens

If you follow the recommended care tips, your sun-tolerant impatiens should stay healthy and vibrant throughout the growing season. Here are some additional tips to ensure success:

Water the plants regularly, making sure the soil stays consistently moist

Sun-loving impatiens require regular watering to maintain their moisture levels. Make sure the soil stays consistently moist, but avoid overwatering, which can lead to root rot.

Pinch back leggy growth to encourage bushier, more compact plants

Deadhead spent blooms regularly to keep the plants looking neat and to encourage continued blooming

Removing spent blooms from your sun-tolerant impatiens will prevent them from wasting energy on seed production and encourage continued blooming. Use sharp scissors or pruning shears to cut off the spent flowers just below the base of the stem.

With proper care, these varieties of impatiens can thrive in locations that receive full to partial sun.
