Impatiens

Impatiens need to be watered regularly, though not overly. Like other flowering houseplants, they should be watered when the top of the soil is dry. Do not let the soil dry out completely or become soggy. When watering, it's important to make sure the water penetrates all the way down to the roots. A good way to ensure proper water penetration is to slowly pour water onto the soil until it starts to come out of the bottom of the pot. A regular watering routine is best, making sure to keep the plant moist at all times.

Impatiens generally prefer shady areas that have bright indirect light. If a plant begins to look weak and thin with long stocky stems, it is an indication that it is not getting enough light. When placed in direct sunlight, the plant will quickly wilt and its foliage will burn. When given in sufficient amount of light, impatiens will produce new side-shoots, wide and dark green leaves, and more vibrant flowers.

Impatiens prefer temperatures of 70-85 °F (21-29 °C) in the daytime and 65-75 °F (18-24 °C) in the evening. They don't do well in temperatures below 60 °F (16 °C) or above 95 °F (35 °C). If temperatures drop too low, the plant will wilt and its foliage may discolor.

Impatiens like humid environment, so regular misting with a spray bottle is beneficial, especially in dry, air-conditioned environments. Increase humidity by placing the pot on a tray of moist pebbles. You can also purchase a humidifier to increase the humidity levels in the room.

Impatiens prefer a light and well-drained soil that is rich in organic matter. A well-draining soil mix is recommended, such as equal parts of potting soil, perlite, and compost. The ideal pH range is 6.0–7.5.

You can fertilize your Impatiens once every two to four weeks from spring to early fall using a balanced liquid fertilizer. Fertilization with a slow-release granular fertilizer such as 8-8-8, 10-10-10, or 12-12-12 is also beneficial. Aim to fertilize your impatiens at about half the strength recommended on the label, as too much fertilization can lead to plant burn and discoloration. Reduce fertilization in late summer and discontinue it in the winter.

Impatiens are vulnerable to common houseplant pests such as aphids, mites, scale, and caret worms. Aphids are the most common and visible pest. They can be identified by their small, green or black bodies and white waxy coating. If not treated, the plant can become weak and defoliated. Inspect the plant closely for any signs of pests. If they are found, spray the plant with a mixture of water and insecticidal oil or soap. Repeat spraying every two to three days for three to four weeks to ensure the pests are eliminated. Wash off any dead pests with soapy water and a soft brush.

Repotting your Impatiens should only be done every two to three years depending on the size of the pot and the size of the plant. A general rule is to repot when the roots start to circle around the pot or when the top growth of the plant exceeds twice the size of the pot. When repotting, use a container one size larger with good drainage. Then, gently remove the plant and loosen the roots. Place the plant in the new pot and fill with a soil or potting mix suitable for your plant. Prune any dead, diseased, or damaged roots and lightly press the soil around the base of the plant.

Pruning of impatiens is not necessary as they tend to maintain a neat, compact shape without it. If you do need to prune your plant for aesthetic reasons, use clean, sharp shears or pruning scissors. Avoid removing more than one-fourth of the foliage off of the plant in one go, and trim the stems back to the desired length. Prune actively growing plants in the spring to promote bushiness.

Mulching around impatiens is not required but it can help keep the roots cool and prevent weeds from growing. Use an organic mulching material such as wood chips, shredded bark, or composted leaves.

Propagate impatiens by taking stem cuttings in the spring or early summer. Use a sharp pair of scissors or knife to cut about four inches of the stem and remove the lower leaves. Insert the stem in well-draining soil mixture and place in a warm, bright spot and keep the soil moist. Transplant your newly formed impatiens into a larger pot when the roots are well established.

Although Impatiens do not require any support, you can avoid stem breakage due to excessive bending by providing support. A small stake or trellis can be inserted into the pot before planting to provide extra support.

During the winter months, your Impatiens will become dormant and require less water. This is a rest period and all fertilization and pruning should be stopped. Water sparingly and avoid over-watering, as this could lead to root rot. Increase watering If the plant shows signs of wilting.

Impatiens are not considered toxic to pets, but it is best to keep them away from nibbling animals.
