3 Tips for Protecting Your Vegetable Garden From Frost

by Carolyn Kay 05/18/2025

Cold weather can be bad news for vegetable gardens, especially if unexpected. While many plants are hardy and frost-resistant, most tender vegetables cannot survive sudden freezing temperatures. Luckily, there are some measures you can take to protect your garden from an unexpected frost. Here are some tips to remember:

Water During the Day

Adjust your watering schedule to ensure you're watering during the day. The key is to saturate the soil rather than leave extra moisture on the leaves. Damp soil can trap heat and insulate the roots of the plant, protecting them from cold. As the water evaporates, it will keep the air slightly warmer near ground level.

Cover Crops With Blankets & Sheets

Old sheets and lightweight blankets can make great DIY frost protection. Use garden stakes, hoops or other supports to create a low tent over the veggies with the sheet or blanket. This will keep them insulated and protect the tender leaves from freezing. Another great tip is to use pillowcases on your tomato cages--just make sure to remove all of the fabric in the morning so the plants can get the light they need.

Shield With Plastic Containers

Plastic is an incredibly efficient insulator. Many gardeners build vegetable greenhouses out of plastic sheets to keep the plants safe and warm in cold climates. Plastic sheeting is a convenient option because you can cut it to size; however, using plastic bins, storage boxes, garbage cans or any other plastic container works just as well. Place them upside-down over your plants to shield them from the frost. This is especially effective for seedlings and tender greens.

These are just a few ways to protect your garden from freezing temperatures. For a thriving garden any time of year, make sure to research the specific needs of each plant so you know where to focus your efforts.

As a Real Estate professional, I specialize in helping my clients buy, rent or sell properties in Westchester County. I am passionate, dedicated and committed to my clients and my first priority is to provide them with first class service and guidance throughout the entire process. It has been said that I go above and beyond for my clients to get the deal closed! I have experience working with clients who have financed their purchases with either a conventional, VA or FHA loan and have a good understanding of how they work; no sale is too big or too small for me to take on. My family and I relocated to England for 2 ½ years, this was a wonderful experience but at the same time, it was overwhelming. I have first hand knowledge of the challenges as well as the positives in discovering a new community. I was born and raised in Scarsdale and once married, my husband and I decided to raise our two daughters here. Both of our daughters successfully graduated from the Scarsdale schools and are both married, living and working in Manhattan. After living in the same house for 30 years my husband and I took the leap, sold our home and bought and renovated a condo townhouse in another town. Once again we are discovering a new community and fully understand the highs and lows of selling a home we loved and buying and making a new home. I feel that my personal real estate experiences have made me more in tune with my client’s needs and therefore better able to help them navigate through the complex process. Please call me so that I can put my knowledge and experience to work for you.
