Arctic Blast of December 2022
Winter Injury Expectations

The arctic blast we experienced this past December was not only tough on us and our homes, but our gardens too. We are seeing signs of winter injury on many plants from the low temperatures and high winds during this extreme event. 

Some broadleaf evergreens in our area seem to have been hit the hardest, including hybrid hollies, nandinas, abelia, mahonia, southern azaleas, laurels, bamboo, and aucuba. We also expect to see injury on plants that are marginally hardy in our area such as crapemyrtles, sweet box, and leyland cypress.

While these and many other plants may appear to be dead right now, DO NOT start cutting things down or removing them just yet. The severity of the damage and best course of action will range depending on the type of plant as well as its location, health, and age. We will not be able to fully evaluate the extent of each plants injury until at least early April at which time we will post on our social media about individual plants affected and the best course of action for that particular plant. 

Wondering how you can try to lessen this type of damage to your plants in the future? 

  • Plant only fully winter-hardy plants for your USDA zone.
  • Do not stimulate growth in the fall with pruning or fertilization.
  • Keep plants properly hydrated in the summer and fall to prevent drought stress going into winter.

The bottom line is that we must all accept that Mother Nature is ultimately in control. This type of damage has happened before and it will happen again. Experimentation and death are always going to be a part of gardening, no matter what level of experience you have, so stay curious and re-frame this winter event as an opportunity to learn more about your garden. 

Our extensively experienced professionals are always here to help, so if you have any additional questions regarding winter injury please send them to Stay tuned for more winter injury updates on our website and social media this spring.

Frost Guide

Frost Free? You decide…

According to the National Oceanic & Atmospheric Administration the estimated last day of freeze for Metro Louisville is April 1st – 15th; however, because we are in a “warm pocket” surrounded by “cooler counties” this puts us at higher risk for a drop in temperature later than estimated.


Some plants can be damaged or even killed by frost or freeze, so it is important to use this information as a guide for scheduling your spring plantings and gardening activities. Cold-sensitive annuals, warm-season vegetables, and tropical plants, including houseplants that are taken outside, will need to be protected from the potentially damaging frost or freezes we might see in the coming weeks. Plants with high frost/freeze sensitivity include basil, tomatoes, peppers, sweet potato vine, annual vinca, impatiens, and other plants fresh from the greenhouse that have not had a chance to harden off.


In addition to air temperature, the soil temperature is also an important factor in the germination, establishment, and production of many warm-season annual flowers and vegetable crops, especially tomatoes and peppers. This is why, even if we don’t have a frost or freeze in late April or early May, you still need to wait to plant. While the air temperature warms up quickly the soil warms up slowly. Planting some crops too early before the soil temperature is 60 degrees Fahrenheit or higher can cause stunting and reduced production even if the air temperature is warm and the growing season is picture-perfect.


March and April is a great time to plant things that are NOT sensitive to potential cold snaps or soil temperatures. This includes hardy trees, shrubs, and perennials, as well as early spring crops like pansies, lettuces, kale, and more. Fresh deliveries of plants and gardening supplies are arriving daily, so stop in soon to check out what’s new.
