Traditionally, January and February are the coldest months in South Florida. Boy, have we experienced that this year! Landscape can be damaged when temperatures drop or fall below freezing. However, most frost damaged landscapes can easily recover with a little TLC. Follow our steps to help nurse your landscape back to health and prepare for the upcoming spring season.
Diagnose the Damage
Frost damaged plants usually have droopy and discolored leaves. Sometimes they even appear “burnt” with brown, white, yellow or red discoloration on the leaves. You can assess damage by using your fingernail to scrape the bark off. Cold damaged branches and trunks will be black or brown when bark is removed, while cold injured branches and trunks will still be green.
Although you may feel the need to give your droopy and burnt landscape a boost of nutrients through fertilizer, it is best to wait until spring. A post-freeze fertilizer application will stimulate new growth, but that new, tender growth will fall victim to the elements if we get more cold weather.
Trimming and Pruning
The cardinal rule for trimming and pruning post-freeze is: less is more. Your landscape has already suffered enough, do not go overboard with the clippers. Wait a few weeks and monitor temperatures to make sure cooler weather has passed. Although unsightly, the dead or damaged foliage can actually help insulate plants from future frost damage. New, green growth will begin to sprout in a few weeks, which will act as a guide for where to trim and prune. When pruning palms or trees, leave as much green as possible. If green is hard to come by, leave about half the damaged fronds or branches, while removing the other half, and wait for new green to sprout in the spring, before removing the remainder of the frost damage.
Protect from Disease
Frost damaged landscape does not look appealing at this point, but it doesn’t necessarily mean it’s dead. Your landscape is weakened though, which can make it more susceptible to pests and disease. You can help protect it, while on the road to recovery, with these Big Earth products:

Overseed with Rye
Does your brown, burnt lawn have you feeling down? Now is the perfect time to overseed with rye grass; It is the perfect solution for frost damaged lawns. As long as the temperatures are still consistently below 85-90 degrees, rye seed can be used to overseed your permanent (currently brown) lawn like bahia, St. Augustine, Zoysia or Bermuda with green color to get you through the remaining cooler weeks. Once temperatures begin to warm up, rye grass will die out and your permanent lawn will take over once again.Buy Now
