The Snow and Ice is Melting – Now What?

​The temptation is to run outside and start cutting back those pathetic looking shrubs and plants.  No, No, No.  Our last frost date is March 15th.  You do not wish to expose any new growth to freezing temps and the deep freeze could possible happen again.  Be patient.
The exception is if you have a plant that has rotting mushy foliage.  It is a good idea to remove the mush to avoid any fungal diseases.  If the leaves are brown or hanging down, wait until it is warmer.

Shell ginger is badly affected by the cold, but it should come back.  Cut off the dead foliage in March and when we have some warmth, new shoots should appear.  The same thing with Philodendrons.  They may lose all of their leaves, but they will resprout.  It just takes time. 

Shrubs like Plumbago really should not be planted in our zone.  They bloom profusely and thrive in Florida, but we are pushing the envelope on using them here.  Duranta will have its top leaves turn black in the below freezing temperatures.  Cut out the black leaves when it is warmer and they will grow back their bright yellow color.

Ferns are problematic.  Boston ferns as well as Kimberley will die back possible to come back, but they take awhile.  Native ferns like Southern shield or autumn fern will make it through unscathed.

I love Salvias, but I am doubtful about most of my plants surviving.  It will be a matter of wait and see.  Many are not hardy perennials and are native to warmer climates.  Strangely enough Geraniums (they are really Pelargoniums) sailed right through and are still blooming through the ice and snow.  A native of South Africa, you would expect them to succumb.  Snapdragons, pansies, and diantha also are still blooming as if nothing happened.
​
Roses can be cut way back on Valentines Day.  Mine are still blooming, but they need to be brought down  in order produce fresh growth.
The most important advice that I can give you is to be patient.  Do not sound taps or give a plant last rites until the end of April or beginning of May.  Our plants are more resilient than we think.  And I am beginning to think that they are more resilient than I am.
