Growing Impatiens Plants The Essential Guide

Impatiens plants are a favorite garden flower that is easy to grow, colorful, and maintenance-free. But to truly enjoy these plants’ beauty and charm, it’s essential to understand how to care for them properly. This guide will provide you with all the essential information you need to get started on growing and caring for Impatiens plants in your garden. From soil and lighting requirements to pest and disease prevention, you’ll have a comprehensive overview of the essential steps to ensure your Impatiens plants are beautiful and healthy.

What Is an Impatiens Plant?

Impatiens (Impatiens walleriana) is a genus of over 1000 species of flowering plants that are native to the tropics and subtropics of the Old World. They are members of the Balsaminaceae family, also known as the balsam family or touch-me-not, due to the explosive nature of their seeds. Impatiens plants are popularly grown for their colorful flowers and ability to survive in dry and wet soils.

Impatiens plants are annuals, meaning they only live for one growing season. These plants grow best in partial shade and moist, well-draining soil. They have a mounding habit and can reach heights of up to two feet when mature. The most common flower colors are white, pink, and purple.

Impatiens Plant Care

When it comes to growing impatiens plants, proper care is essential for producing healthy, vibrant blooms. Knowing how to care for impatiens is the key to success! Here are a few tips to ensure your impatiens plants thrive:

Soil & Location

When selecting the soil for your impatiens, you should ensure it has a good balance of organic matter. A good mix of compost, peat moss, and garden soil is ideal. If you are using a potting mix, make sure it is a light and airy mixture with enough organic matter to produce good drainage. If your soil needs amending, you should add either organic matter or sand to improve aeration and drainage.

The location should be well-lit but not in direct sunlight, which can cause scorching and wilting. If you live in a hot or dry climate, the morning sun is preferable, as it is less intense than the afternoon sun. You should also avoid planting your impatiens in windy locations as this can cause the leaves to dry and wither.

When planting impatiens, ensure they are spaced out and given enough room to grow. Planting too close together can lead to overcrowding and disease. The ideal spacing will depend on the type of impatiens you are planting, so it’s best to consult a gardening book for more information.

Light Requirements

Impatiens prefer bright, indirect light, which will help them produce more flowers. If they are grown indoors, they should be placed near a window that receives direct sunlight or supplemented with a grow light. If the plants are outdoors, be sure to provide them with some shade during the peak hours of the day, as too much direct sunlight can cause burning and scorching in their leaves. Additionally, it is essential to remember that impatiens are relatively intolerant to temperature extremes, so any sudden drops or increases in temperature could cause further damage to the plant.

Watering Requirements

Impatiens must be watered regularly, as they require consistent moisture to grow and thrive. The amount of water you need to give your impatiens depends on your area’s climate and soil type. Generally speaking, impatiens should be watered every two to three days.

If you live in an area with a hot climate, the soil dries out quickly, and you may need to water your impatiens more often. If you live in a cooler climate, you may only need to water your impatiens every four to five days. It’s also important to keep an eye on your plants and ensure they receive enough water. If the soil looks dry, you’ll need to water them more frequently.

When watering your impatiens, it’s essential to ensure the water reaches the root zone. The best way to do this is to water them deeply. To ensure your impatiens receive enough water, water them until the top inch or two of the soil is moist. If you use a sprinkler, water the plants until the area is saturated.

Impatiens are sensitive to over-watering. When they are overwatered, they can develop root rot, which can cause your plants to die. Therefore, it’s essential to ensure you don’t overwater your impatiens. This can be easily avoided by ensuring the soil can dry out between waterings.

Finally, a moisture meter is the best way to ensure your impatiens get the right amount of moisture. This device is placed in the soil and measures the moisture content of your soil. When the soil is too dry, it’s time to water your impatiens. Moisture meters are easy to use and can be found at most garden stores.

Fertilization Requirements

Fertilizer should be applied at least once a month during the growing season. Organic fertilizers, such as compost or fish emulsion, can be applied at 1-2 tablespoons per plant. For synthetic fertilizers, follow the instructions on the package, as each type of product may have different application rates.

Applying fertilizer in the morning when the soil is still wet from moisture overnight is best. This will help the fertilizer to soak into the soil quickly and be available to the plant roots. Do not forget to water the plants after applying fertilizer, as this will help the nutrients fully absorb.

Remember that impatiens is a shallow-rooted plant that needs nutrients near their roots. Be careful not to over-fertilize, as a buildup of nutrients in the soil can be harmful to the plant. If there is a noticeable change in the color of the foliage or leaves, you may need to adjust the fertilizer type or amount.

Also, the fertilization requirements for impatiens may change over time. As the plants become older and more established, they need to be fertilized less often. However, monitor your plants closely to ensure they get the necessary nutrients.

Pruning and Training

When pruning impatiens, it is essential to ensure that the cuts are made cleanly and at the right time. Spring is the best time to prune impatiens since it is in their most active growth phase. When pruning, remove any dead or damaged foliage, as well as any shoots that do not belong in the plant. Use sharp and clean pruning shears to ensure a clean cut.

Training is also essential for impatiens growth. Training involves creating a “framework” for the plant to grow in and can help to ensure that the plant grows in an aesthetically pleasing shape. To train the plant, tie the branches to the support with plant ties or strips of cloth. This will encourage the plant to grow in the desired shape.

It is essential to avoid over-pruning and training. Removing too much foliage from the plant can expose it to sunburn or disease, so it is essential only to prune and train when necessary. Over-pruning can also cause the plant to become leggy or spindly. To prevent this, remove the oldest branches first and try to prune the plant conservatively.

Common Pests and Problems

Impatiens are a beautiful and easy-to-grow plant, but they can be susceptible to a few common problems. To help you keep your Impatiens thriving, here is a guide to some of the most common pests and associated problems.

Common Pests

One of the most common pests to affect Impatiens is aphids. These insects come in a range of colors and sizes and can cause damage to the plant in the form of yellow spots on the leaves or loss of foliage. If you notice aphids, use a hose to spray them off the plant and keep an eye out for more.

Other pests, such as thrips, may also feed on Impatiens and cause injury to the plant. Thrips are tiny and black and can be challenging to detect on the plant without close inspection. If you notice discolored leaves or other signs of pest damage, you may want to consider using an appropriate insecticide.

Common Diseases

Impatiens are prone to several fungal diseases, including downy and powdery mildew. Downy mildew is characterized by yellow spots on the leaves, while powdery mildew is white and powdery. To control these diseases, it is essential to keep the leaves of your Impatiens as dry as possible and to remove any infected plants from the garden.

Root rot can also be a problem for Impatiens, as it causes the plant’s roots to become soft and mushy. To prevent root rot, it is essential to ensure your Impatiens are planted in well-draining soil and to water them deeply but infrequently. If you suspect root rot, inspect the roots and prune away any brown or mushy roots.

Common Problems

In addition to pests and diseases, Impatiens can be prone to nutrient deficiencies, such as iron deficiency or overwatering. Iron deficiency can cause yellow leaves while overwatering can cause the leaves to turn yellow or brown and wilt. To avoid these problems, ensure your Impatiens are planted in fertile, well-draining soil and water them deeply but infrequently.


In conclusion, growing impatiens plants can be a rewarding experience for gardeners. These flowers can make any garden pop with suitable soil, light, and water requirements. With proper pruning and training, the size and shape of these plants can be manipulated to create a truly unique look in the garden. Although pests and diseases may cause some problems, most can be overcome with a good prevention program and proper management when they do occur. With the right care and attention, you can have a stunning and vibrant garden full of these beautiful flowers.
