To keep your impatiens plants alive over the winter, maintain the temperature at 55°F. This temperature can keep your impatiens flowering during this season. Otherwise, they'll be fine if it's warmer than 45°F.

Impatiens are high-temperature plants that develop at their finest at 70°F to 80°F during the daytime and 65°F to 70°F at night. 

To keep your impatiens alive during the winter, it would be best to individually plant them in pots and keep them at a temperature of 55°F. Alternatively, you can position them under the staging in a heated conservatory on a windowsill. 

Please follow the methods below to overwinter your impatiens.

1. Bring In The Impatiens

After inspecting and grooming the impatiens, treat them for any pest or disease concerns. Also, before putting them in an area with bright lighting, warmth, and a moderate amount of moisture, it would be best to cut off about a third of the plant.

If you put the plant in places with inadequate natural light, it would be best to supplement the light. Place a plant light approximately 5" above the plant's top for around 12 hours daily for best results.

2. Take Tip Cuttings

Take 3" to 6" long tip clippings to keep your Impatiens from appearing twisted and woody at the end of the winter season. We suggest utilizing a knife or sterile scissors if you want a nice and clean cut.

Once you finish, eliminate the leaves at the lower part of the cuttings, then plant the clippings in a potting mix. Ensure that the mixture is light and moist. Further, put the clippings in a location that has filtered light.

You can also utilize a plastic bag as a greenhouse. To use it, place the impatiens inside and leave it uncovered rather than putting the plastic upside down. You'll know that the clippings produced root when you notice new growth.

Prepare to slowly increase the size of the containers or ease out of them when spring arrives. Please note that it is best to fertilize only when the plant is actively growing and when the soil is consistently damp.

3. Collect Impatiens Seed

Although many hybrid plants produce healthy seeds, their offsprings rarely resemble the parent plant. Therefore, only collect seeds from non-hybrid impatiens.

Start sowing the collected seed indoors at the beginning of March. Add seeds to the moist soilless mix and push down. Further, you can add a thin coating of medium over the seed. Remember to keep seeds warm.

If you want to incorporate impatiens into your garden, we offer the following tips to guide you:

Check The Soil Temperature

Before you plant your impatiens in the ground, it would be best to confirm if the soil is already warm since they are oversensitive to cold weather.

We suggest setting out the transplant of your impatiens in early spring. Or you might want to sow impatiens seed inside your home 8 to 10 weeks before the last frost.

Plant Impatiens In Soils Rich In Organic Matter

You can plant impatiens in soil that contains lots of organic matter. You also need to ensure that the soil drains well.

If you have the Impatiens walleriana variety, we suggest placing them only in an area where they can get light to medium shade. On the other hand, the New Guinea Impatiens should always have their roots moist to tolerate more direct sunlight.

Space Impatiens Appropriately

If you want to achieve taller impatiens, it would be best to place them closer together. But if you go for a wider spacing, they will spread out widely, filling in the gaps. Also, if you want to use them as ground cover, you should space them farther apart.

Use Well-draining Potting Soil

Your plants will thrive in a general purpose, well-draining potting soil that contains a slow-release fertilizer.

Select impatiens with similar watering and exposure needs if you plan to grow them with other annuals or perennials in the same area.

How To Care For Impatiens

Adequate Watering

Dry spells can cause withering in impatiens. Thus, it would be best to water them frequently to keep the soil wet.

Improve the soil's water-retention capacity by adding organic matter, then covering the area with mulch. If your impatiens are in pots, you may need to water them daily, especially during dry, hot weather.

Fertilizing Correctly

Use a slow-release granular fertilizer or compost when planting impatiens. If you want to grow them in containers, we suggest feeding your impatiens with liquid fertilizers more often.

Proper Pruning

Impatiens don't require pruning, but if it grows too long and slim, you can pinch them back to stimulate bushier growth. Your plants will hit back in a few days with a fresh round of blossoms. Moreover, since they clean themselves, you won't have to deadhead impatiens flowers.

Pests and Diseases

Impatiens have several pests or bug problems. These include:

  • Impatiens Downy Mildew
  • Flower Thrips
  • Spider Mites
  • Whiteflies
  • Aphids
  • Gray Mold
  • Fungal Leaf Spot
  • Root Know Nematode

To get rid of these stubborn pests, use either the following solutions and procedures:

Neem Oil

For most pest problems in your impatiens plants, this oil is an effective solution to get rid of them. All you need to do is to put some in a spray bottle and spray the infested areas.

Insecticidal Soaps

You can use this solution in thrips- and aphid-infested impatiens. This solution doesn't need mixing since you can purchase it in a spray bottle. However, you must be careful when using it as it may irritate your eyes. 

Insecticidal soaps kill thrips and aphids by breaking down their coating and destroying cellular function. So, it would be best to coat the plant thoroughly to eliminate them.

Horticultural Oil Sprays

If you can't find insecticidal soaps, you can use horticultural oil sprays as an alternative. It is less toxic to humans. However, we suggest using safety gear since it can irritate your eyes and skin.

Just like the first two solutions, you must spray it on the infested areas in your impatiens. Horticultural oil sprays work by drowning the pests and their larvae. Please note that you should only use this solution when the temperature is below 90 °F.
