When planting Busy Lizzie and other Impatiens plant members in the garden, the seed should be sown on the surface following the last frost of spring.
Busy Lizzies like to grow in a shaded area of the garden, though they are tolerant of sun.
Impatiens plants prefer a rich, well manured soil of pH 6 to 7.
If you first plan to grow Busy Lizzie and other Impatiens species indoors, then the process should be started about 9 or 10 weeks in advance. Plan to transplant out a few weeks after the last frost of spring.
For gemination indoors, sow the seeds in vermiculite, and supply high humidity and a temperature of 21 to 24 degrees (about 50°F).
As plants are partial to leaf rot, it is important to only water the seedlings from below. The germination time is typically from one to four weeks.
Once growing Impatiens should be pinched back to encourage branching. They should be fed a couple of times, and be well watered.
If you would like further plants, then cuttings can be taken in the spring or autumn.
Alternatively, let the plants set seed in situ.
