Protect your plants against tonight’s hard freeze in the Smokies

While it won't be cold enough in the Smoky Mountains to make pipes freeze up tonight, it will be cold enough in the Smokies to damage some plants in your gardens by freezing tender new buds and shoots.

The first thing to do to protect your plant is bring inside any sensitive flowering plants that you can. Too many plants to bring inside or the pots are too large to move them around? You can lay them on their side and cover the plants with a cloth.

If you are covering plants make sure to not cover them with plastic unless it can not touch the plants as plastic touching plants that freezes will cause more damage. You can separate the plastic cover on your plants with cloth. Though it probably won't be brutally cold tonight in the Smokies to have to worry about this, sometimes it is best to cover cloth that is over plants with a layer of plastic to block the wind.

Pine needle mulch and leaf mulch both work great to protect plants against freezing - just be sure to remove it the next day so the plants warm up.

Another good idea is to make sure the soil is very damp before it gets cold as the damp soil tends to stay warm longer than dry soil. You do not want plants to be wet when the freeze begins as that will cause more intense damage.

Last call for volunteers to help the GSMNP remove non native plants.

Non native plant removal will take place this Saturday in the Big Creek section of the Great Smoky Mountains national park and Your Smokies officially declares that for this weekend Tennessee and North Carolina are both to be called "The Volunteer State".

OK maybe my official declaration doesn't mean much, but your help removing non native plants that have invaded the Great Smoky Mountains for a few hours would really help the national park!

We are looking for a few good hands willing to enjoy the fresh air and beauty of the GSMNP while helping by pulling out 2 plants that are disturbing the ecology of the park.

Bring nothing but yourself (and maybe a few friends); a great attitude, water, lunch and a pair of gloves wouldn't hurt. Meet us before 10:00 am in the picnic area and expect to be done by 2:00 pm.

Weather Damaged Smoky Mountain Plants

Easter weekend unseasonable cold weather in the Smoky Mountains especially in the higher altitudes of North Carolina has damaged plants and crops but will they recover?

The answer for most part is yes although some food crops will have a diminished if any crop this year as a result of the unseasonable late deep freeze for no less than 3 nights in a row.

The severity of the damage is dependent on the species, as well as the extreme in temperate, durations and the preexisting health of the plants. For example the trees in the Smoky Mountains such as poplar and gum will replace damaged foliage rather quickly possibly this season whereas oak and hickories will take as long as a year to replace leaves damaged in the freeze.

Weather damage to foliage can be identified by the condition of the leaves for example if the leaves are purple or blacked they are most likely dead from ice crystals forming inside the leaves that have punctured cell membranes in the leaf. This will cause the leaf to lose its natural turgidity (stiffness) and lead to the leafs eventual demise.

Plants that are affected in this manner with enough leaves that die become stressed which is exacerbated id the plant attempts to re-flush (grow) new foliage as to do so the plant will have to draw upon already depleted starch reserves. If there any significant additional stresses to the plant during this growing season such as drought, insects or diseases there is a high probability the plant will die.

Less detrimental to the plants of the Smoky Mountains who weathered the last strong frost this year are those that exhibit is a rolled or drooping appearance to the leaves called "epinasty" which is caused by the loss of hydration in the leaves.

Gradual warming and plenty or rain are the best cures for both conditions. Today's snow in the Smoky Mountains is helping with the rehydration the plants require, but the cold weather may be producing further damages especially ion the colder higher elevations. If we are lucky tomorrow warming temperatures and rain will help.

If plants in your Smokies garden were damaged by the heavy freezes the best course of action is a heavy soaking twice a weekend refrain from fertilizing this calendar year.
