How to care for the Caucasus forget-me-not 'Jack Frost'?
The Caucasus forget-me-not 'Jack Frost' requires regular watering without waterlogging, little fertilization, occasional pruning and is hardy. Pests or diseases are rarely a problem as long as care is taken appropriately for the location.
What should you pay attention to when watering?
So that the silvery leaves look beautiful even in summer, care for 'Jack Frost' should include regular water supply. This is especially true in hot and dry times. This variety does not tolerate dry soil. Likewise, it can't get used to accumulated moisture. Therefore, water them when the soil on the surface has dried.
Does this perennial need weekly fertilizer?
It is not necessary to fertilize this perennial every week. If you work some compost (€41.00 on Amazon) into the soil before planting, you won't need to fertilize the Caucasus forget-me-not 'Jack Frost' at all in the first year. Basically, it is recommended to fertilize this perennial once or twice a year when grown outdoors and every month when grown in containers.
How do you cut this variety correctly?
In general, 'Jack Frost' doesn't necessarily need a cut. The height of growth is and remains low at a maximum of 40 cm. But cutting has a beneficial effect on the life expectancy of this perennial and the strength for flowers.
You should pay attention to this:
- generally well tolerated by pruning
- remove wilted flowers to prevent self-seeding
- cut off old inflorescences (up to the upper stem leaves) around May/June
- cut back to just above the ground in autumn
Is wintering necessary?
This specimen is extremely hardy. Therefore, it does not need to be protected from frost in winter. However, if you live in a harsh location: cut the perennial back in autumn and protect it in the root area with brushwood!
Are there any pests or diseases that may play a role?
If the substrate is not dried out, the location is not in the blazing sun and the care is correct, 'Jack Frost' is less susceptible to diseases. Pests also only appear in exceptional cases. The risk of snail damage is low.
