Understanding Frost Advisories


Frost advisories alert us when temperatures are likely to fall to 36°F or lower. Frost forms quickly, especially under clear skies and light winds. For gardeners, getting ready to protect sensitive plants is crucial.


Young vegetables, blooming flowers, and tender shrubs are at high risk. Keep a close eye on the weather to mitigate damage to your garden. Remember, awareness is vital for protecting your green investments.


The Impact of Frost on Outdoor Plants


When frost develops, ice crystals form on plant leaves, causing cellular damage. This damage can lead to wilting and brown spots as the sun heats things up again. Young plants and perennials are particularly vulnerable as the growing season ends.


Here are common plants at risk during early frosts:


  • Tomatoes: Just 32°F can ruin exposed tomatoes, making them mushy.

  • Peppers: These tender plants perish when temperatures dip too low.

  • Annual Flowers: Flowers like petunias and geraniums typically suffer frost damage.


Being proactive during frost advisories helps protect your garden from unnecessary harm.


How to Prepare Your Garden


Here are effective steps to defend your outdoor plants during a frost advisory:


1. Cover Your Plants


Use row covers, blankets, or burlap sacks to protect your plants. Make sure the covers touch the ground to capture warmth. Weigh down the edges with rocks or bricks to keep everything secure during wind gusts.


2. Bring Potted Plants Inside


If you can, move potted plants indoors, or at least into a garage or shed where it is warmer. If you cannot move them, place them near a wall of your home to gain some extra warmth from the heat it radiates.


3. Water Before Frost


Water your plants 24 hours before frost hits. Moist soil retains heat better than dry soil, which increases the chances of plants surviving the cold. Be careful not to overwater, as too much can cause root rot.


4. Apply Garden Mulch


Spread a thick layer of mulch around plants for extra insulation. Organic materials like straw, wood chips, or shredded leaves work best and can keep soil temperatures stable.

5. Harvest What You Can


If frost threatens your garden, make sure to harvest ripe vegetables. This protects your bounty and minimizes waste. You can even pick green tomatoes to ripen indoors—many will turn red perfectly in a sunny spot.


Adjusting Your Outdoor Activities


Frost advisories not only impact gardens but can also influence your outdoor plans. Here are smart ways to adapt:


1. Monitor Weather Reports


Stay updated on weather forecasts leading up to the advisory. This will help you adjust plans and avoid surprises.


2. Plan Warm Weather Activities


Organize activities like leaf-peeping or visiting local orchards during warmer daytime temperatures. The sunshine will enhance your experience.


3. Reschedule Outdoor Events


If you have gatherings planned outdoors, consider moving them to a date when it’s milder. Indoor options can provide a comfortable alternative.


4. Engage in Indoor Gardening


Use the time indoors to plan for improvements in your garden. Researching spring planting strategies or starting seeds indoors can be productive ways to stay involved.
