U.S. zones have an annual impatiens that lasts one full growing season. Perennial impatiens (in Zones 10 through 12) will come back every year when properly cut and pruned.

Here’s a pretty interesting video about the process:

Will my impatiens survive winter?

Impatiens plants that bloomed enthusiastically through the previous spring, summer and fall are probably all tuckered out and won’t survive the winter. The impatiens set out later in the season and are usually located in warm locations with good drainage. If you’re looking for a plant to grow in your garden, you can’t go wrong with any of these.

Do impatiens need to be cut back?

We recommend pruning Impatiens to prevent the plant from looking overgrown. Cutting back an overgrown plant will encourage new growth and make the plant look bushy. Taking a proactive approach will encourage flowering and healthier branching and will lead to a more attractive plant.

Do impatiens reseed themselves?

Impatiens often reseed in the garden, but the seedlings will gradually revert to producing tall plants with a mix of colors unlike those originally planted. Depending on the variety, Old-Fashioned Impatiens range in height from 8 inches to 2 feet tall. The best fertilizer for this plant is a mixture of 1 part perlite and 2 parts peat moss.

This will provide the plant with the nutrients it needs to grow tall and healthy. If you do not have access to this type of fertilizer, you can add a small amount of compost to the potting mix to help the soil absorb the fertilizer.

How cold is too cold for impatiens?

Although impatiens thrive in Mediterranean climates, they prefer shaded temperatures of 65 to 70 degrees Fahrenheit. If the temperature falls below 60 degrees F, impatiens will die. Impatient to live in the shade, some species may be attracted to the heat of the sun, which can cause them to overheat and die.

How do you multiply impatiens?

Water can be used to achieve impatiens rooting. It is possible to root easily using this method. Simply remove any lower leaves and place the cuttings in a glass or vase of water, up to the first couple of nodes. The next step is to remove the leaves from the plant. This can be done with a sharp knife or a pair of tweezers.

The leaves should be removed as soon as possible, as they are very sensitive to light and heat. If you don’t remove them soon enough, they will die and you will have to start all over again. It is best to leave them in place for at least a week or two to allow the roots to grow.

Once you have removed all of the leafy parts, you can then cut off the stems and cut them into small pieces. You can use a knife to do this, but it is much easier to just cut the stem off with your fingers. Be careful not to cut too deeply, or you may damage the root system. When you are ready to harvest, simply pull out the entire plant, leaving only the top and bottom leaves.

Can impatiens be grown as a houseplant?

Impatiens can be grown successfully in normal room temperatures with a humidity of at least 50%. They will need high humidity if the temperature is over 75 degrees. Plants should be placed on saucers of moist pebbles with their foliage exposed to the sun.

Plants should not be allowed to dry out between waterings, as this will cause the roots to rot and the plant to wilt. The plants should also be kept in a well-ventilated area, away from drafts and drafts from windows and doors.

They should never be left out in the sun for more than a few hours at a time, or the leaves will turn yellow and die.
