Impatiens is a beautiful annual that makes an excellent houseplant or summer bedding and container plant. Here’s how to grow impatiens in your garden!
Impatiens is also known as “Busy Lizzie,” and its name is a Latin word that describes the way its seeds shoot out of its pods when ripe (the slightest touch can make a ripe impatiens seed pod burst open and scatter its seeds). Generally, impatiens like shade and moisture.
PLANTING
Plant impatiens transplants after the last spring frost. See your local frost dates.
Impatiens prefer humus-rich, moist, and well-drained soil. Make sure the plants have some shelter from the wind.
The closer impatiens plants are, the taller they will grow, so space accordingly (impatiens plants can grown anywhere between 6 and 30 inches tall). For flower beds, plant 8 to 12 inches apart so the plants will stay low to the ground.
You can mix in compost or a slow-release fertilizer before transplanting to help the plants.
If you have impatiens plants in containers, like window boxes, use a sterile or soil-less growing mixture to ensure better drainage for the plants.
Learn more about soil amendments and preparing soil for planting.
CARE
The most important thing to remember about impatiens plants is to water them regularly. Keep them moist, but not too wet. If the plants dry out, they will lose their leaves. If you over-water the plants, this could encourage fungal diseases.
Remember container plants will need more water.
