Heliconia plants are tropical and therefore susceptible to damage from hard freezes.

Our two past winters have been extremely moderate. But we have already had a killing freeze this wintertime. So tender vegetation like variegated shell gingers and Hawaiian ti crops experienced their leaves burned again seriously by the post-Christmas freezes.

There probable has been some stem destruction to these chilly-sensitive vegetation, far too. But it can take time right after a freeze ahead of you can notify how in depth the stem damage was. For that cause, and mainly because we will most most likely have more freezes, it is sensible to wait right until at the very least a minimal afterwards in the winter season to commence pruning these crops back again. There is no damage in waiting around until late February if you would like.

Young citrus vegetation are also prone to freezes, such as we experienced just lately, when the temperatures dip down into the mid to reduced 20s and keep beneath freezing for 12 hours or so. Satsumas and kumquats could not be afflicted at all, but lemons and oranges are far more delicate.

A temporary greenhouse can be constructed using PVC pipes to protect cold-sensitive plants during freezes.

Protection from the cold

So, what if we have more and probably even a lot more serious hard freezes this winter? How do you secure delicate vegetation? If the plant is small more than enough that the entire plant can be included, that may perhaps be an solution. But be informed that just throwing a sheet or gentle blanket, or even a plant frost protect, around the plant will not give substantially security against a really hard freeze.
