Winter Hardiness

Determining if a plant will be hardy enough for your garden, or wherever you intend planting it is far from an exact science. On the plant side it's not too bad as the hardiness of most plants has been reasonably well established. The trouble is knowing, not just the climate of your geographical area, but also the microclimate of the planting area, for example, aspect, exposure to sun, wind, rain, soil condition and proximity to a wall or if there is shelter from a tree overhead.

Therefore it's no good us saying, ‘oh so you live in Norwich - this Yucca will be fine', it really does depend on the local conditions in which it will be planted.

We've put together a guide, that doesn't try to be too specific making it inaccurate, or too vague to be of any use at all.

Included in each plant description there is a one of the terms - Hardy, Fairly hardy, Fairly tender, Tender. Below is a brief outline of what is meant by each term.

Tender - Ideally bring in for winter if not at least protect.

Fairly tender - If in a pot, consider bringing in, depending on its position consider providing protection.

Fairly hardy - If the plant is in a cosy sheltered position the plant should be ok, be a little more cautious with the plant if it is potted.

Hardy - This plant should be fine in all but the most exposed of positions, really only prolonged very cold weather or exposure to strong wintry winds should be of concern.

A sheltered spot, maybe near a wall or fence or under a tree

Generally well drained soil is nearly always preferable to help to reduce freezing in winter

Mulching is another great way to help minimalise the soil freezing in winter.

Protecting the plant is often achieved by wrapping the entire plant or in cases the crown of a plant with Hessian or horticultural fleece.
