Many daisies have poor winter hardiness. If they are in a pot or are generally considered sensitive, such as stems, then they should be overwintered for their survival. But how does it work?
How can you properly overwinter daisies?
In order to overwinter daisies successfully, they should be brought into their winter quarters before the first frost. This should be unheated, cool (5-15 °C) and bright. Planted, frost-tolerant daisies can be protected with leaves, brushwood, fleece or jute sacks. Water sparingly and do not fertilize during wintering.
Bring in before the first frost
Before the first frost sets in - between mid and late October - the sensitive ones are brought to their winter quarters. This should be like this:
- unheated
- cool between 5 and 15 °C
- bright
Protect planted daisies outside
Daisies that you have planted and that are frost-tolerant should be protected if they are in a rough, unprotected location. Even if extreme frost temperatures threaten, winter protection is recommended. The following are suitable for protection in the root area and around the shoots:
- Leaves
- brushwood
- fleece
- Jutesack
Preparation for wintering – not to be neglected
Preparation for wintering is the be-all and end-all. It begins in late summer. From the end of August/beginning of September you should no longer fertilize your daisies. If you do this anyway, the strong supply of nutrients will prevent the plants' shoots from maturing. This makes them much more sensitive to frost.
Shortly before settling in or overwintering, you should also cut back your daisies. Take a pair of sharp secateurs (€14.00 on Amazon) and cut the plants back by about a third. Old leaves and flowers should also be removed at this opportunity.
During wintering
The plants should never dry out while the daisies are overwintering. They therefore need to be watered every now and then. The motto here is to water sparingly. Fertilizer should be avoided entirely.
Tip
Check the daisies regularly for pests and diseases during wintering!
