With so many things in the garden to worry about when the frost comes it is a relief to know that at least your hostas are fully hardy. Every year garden enthusiasts move lavenders, acers and an array of other plants into their greenhouse or inside for the Winter. Others spend hours and hours fiddling around with expensive frost fleece to cover their non hardy plants. This is not an issue with hostas which makes them such a hassle free addition and one less thing to worry about.
Originating from Asia, hostas are no strangers to harsh conditions. Hostas were first discovered in China, Korea and Japan where temperatures often fall well below 0°C in the Winter months.
Do I need to protect my hostas over Winter?
Yes and no. If your hostas are in the ground and have relatively developed then they will be absolutely fine left over Winter with little or no protection. Semi mature and mature hostas in pots will also be sturdy enough to go through a cold Winter unprotected.
If you have recently bought juvenile plants or have taken small cuttings from other hostas in the garden it is sometimes wise to give them a little protection. In the ground your hostas have a better chance if Winter is particular harsh, in pots however it is advisable to give your younger plants some protection.
How do I protect hostas in pots over Winter?
If you have young hostas in pots it is generally a good idea to protect them over Winter. Over a mild Winter it is very unlikely that any plants would die, although if it is particularly harsh you can be left with some casualties. There are several ways you can do this.
One of the easiest ways to protect young hostas over Winter is to put them in an unheated shed or garage in late Autumn. Hostas need temperatures of below 5°C to enter their Winter dormancy. It is very important that your hostas get a full dormancy as this can effect their vigour the following season. In an unheated shed or garage they will be cold enough to go into their dormancy but will not be damaged if there is a hard frost.
Alternatively you put your pots on their sides, this stops them filling with water and freezing. This will help prevent damage to both your hostas and your pots. You could also cover the tops of your pots with plastic or tarpaulin to stop snow and ice building up and melting into the plants.
