Overwintering Roselilies

This question was asked by
Trisha F – 

I am over the moon with the R. Anouska and Dejima I bought from you. they are flowering their socks off and the scent is just amazing. I am growing all five of them in a reasonably sized pot but not sure how to overwinter them.
Do I leave the foliage on until it dies (like most bulbs) or cut them back?. Do I put the container in the unheated greenhouse or are they able to stay outside in the container? Are they suitable for living in the soil all year round? We are in Kent with a rich well drained soil but somewhat open to strong south westerly winds.
Your advice will be much appreciated by me and the lilies!!, Best, Trisha

Ahh thank you so much for your lovely feedback of your lilies.

After the flowering phase of your lilies, it’s advisable to halt watering and trim off only the flower heads, keeping the stem intact. The stem and foliage should be allowed to die back naturally, turning yellow and hollow, typically during the autumn season. At this stage, the stem and foliage can be removed. This natural dieback process nourishes the bulbs, facilitating their flowering in the subsequent year.

The bulbs should remain undisturbed throughout winter, as they prefer a chilly dormant phase. However, it’s crucial to prevent them from becoming waterlogged to avoid rot.

In the spring, provision of a fresh layer of compost is recommended, along with feeding them with diluted tomato feed during their active growth periods. These steps not only maintain the lilies but also enhance their flowering potential.
