Winter care of exotic plants
Ensure these beauties are shielded, says Ruth
AS the temperatures fall it’s time to protect tropical canna lilies, dahlias, agapanthus and bananas. Most need substantial protection, whether they’re left in the floor, lifted and transferred to some frost-free greenhouse or, if potted plants, mulched and proceeded against a sheltered wall or to the greenhouse.
Evergreen agapanthus are less hardy than deciduous types, but can be protected using a thick mulch of straw or chippings over the origins. Potted plants may be transferred to shield, mulched and wrapped in fleece or bubblewrap.
Musa basjoo bananas will tolerate UK winters as long as they do not get waterlogged. Container plants should be trimmed and trimmed, while those in boundaries should have their trunks wrapped in fleece or hessian.
Less hardy Ensete types are best maintained undercover through the winter.
After their foliage has been blackened by the first frost, tuberous canna lilies are cut back, lifted and the tubers divided before being stowed somewhere frost-free in trays of sand or vermiculite that is kept just moist.
Dahlias should be cut and lifted in precisely the exact same style, then their tubers left someplace cool for a few weeks to dry off before being set in trays of sterile sand or compost with the stems uncovered.
Keep checking your plants throughout winter, including more insulation if it’s dislodged, making certain compost is just moist and not soggy, and keeping watch for pests in the greenhouse.
1、Cannas may be stored in trays somewhere mild, frost-free and dry. Make sure their mulch remains just moist through winter.
2、Always leave some stem on lifted dahlia tubers, otherwise they will not take when you weed them up following spring.

1、Boost the pot on feet and top it with a new layer of compost or straw to insulate the roots.
2 、Using sharp, clean secateurs or shears, cut back all the Foliage, leaving around 3ft (1m) of trunk still standing.
3、Wrap the entire kettle in two-three layers of horticultural fleece, tying it securely with garden twine.
4、Finish with bubblewrap for extra waterproofing and insulation. Set the pot somewhere sheltered outdoors or move it to some frost-free greenhouse.
