Learn how to protect plants from frost & snow, so new garden growth survives an April freeze. Includes simple, step-by-step instructions and tips for making the process go smoothly!
Here in Ohio, the spring weather has been both beautiful and renewing, but so unpredictable! We have had gorgeous days where I could actually smell the arrival of summer, but this week, we had the total opposite. The warm weather had forced blooms and buds early, so my peonies were two feet tall, and some of my hosta plants were halfway up. When I saw the weather report earlier this week, I tried not to panic. We were expecting freezing temperatures, snow, and possibly sleet. What would that do to my plants?
The thought of having no peony blooms quickly spurred me into action. I had never been in this situation before, and I wasn’t sure exactly what to do. So I turned to Google, and was able to come up with a plan that I thought would work for my garden. I knew it was important to take into consideration the size of my plants, and how sturdy they were.

What You Need
I set off for the garden center, and after some searching, came home with everything I needed to build little greenhouses around my peonies, allium, hydrangeas, and hosta plants. Here’s what I bought:
Steps To Protect
- The very first thing I did was gather some rocks from my garden border to weigh down the edges of the plastic drop cloths. If you don’t have rocks, anything heavy will work. Pavers, bricks, tile, stakes, etc.
- Install the supports around your plants. This takes patience, because the rings are a little tricky. Once I got the hang of it, the process went very quickly.
- I used the plant supports for the peonies, but not for the hydrangeas. Since the hydrangeas have very sturdy branches, I just draped a piece of plastic over each bush, and tied the tape around the base. (I am so sorry…but I don’t have any pictures of the hydrangeas.)
- Once the supports are in place, drape a plastic drop cloth over them, carefully making sure there is plenty of “give” and room for your plants to breathe.
- Use rocks or some other heavy items to weigh down the drop cloths. As you can see in the image below, I used two wastebaskets that I already had to cover two little peonies. Rose cones would also be a good choice if you have them. This method works great for young or very small plants.
From start to finish, the entire process took just a few hours. To cover the hosta plants, I loosely laid a plastic drop cloth over them, and weighed the edges down with some pieces of tile. I knew the plants might get a little smooshed, but it was better than losing the leaves that were already popping through the soil.
When The Snow Came
At this point, I took a deep breath and hoped for the best! The next evening, right on time, the temperatures dropped, and the snow began to fall. Pictured below is what we woke up to the next morning. I am certain that if the peonies had not been covered, they would have been completely weighed down by the very wet and heavy snow. I’m not sure about the other plants, but it’s always better to be safe than sorry! Like most spring storms, the snow melted quickly, and the green grass was back in business by the next day. I left the coverings on until the night temperatures were well above freezing. So all in all, the plants were covered for three days.
Use Your Own Judgement
I heard from some readers who said it wasn’t advisable to use plastic to cover plants. I used it because the forecast was for heavy, wet snow and sleet. I felt that sheets or towels would get too heavy with several inches of snow sitting on them. I’m certain the plant supports would have collapsed if they had been covered with heavy, snow-covered sheets or towels. The daytime temps while my plants were covered never got over 55 degrees, so nothing was in danger of getting too warm. If your weather forecast only calls for frost, the fabric options would work fine. Definitely use what you think will work the best!

Southwest Indiana experienced the same weather front last week. Digging through sheets to use as shields, I realized that a wet sheet would drag the fragile buds down. Still digging, I ran across big, blue IKEA bags. Unfolded, they maintained their shape and fit nicely over the peonies. A brick anchored each handle. IKEA hack
Living in central Florida now, we do get some temperatures that dip into the low 30’s.I use old towels to cover some of my plants which I had to do a few times this year.Although the snow is very pretty,I surely do not miss it !!
Thank you for this. Although we live in Alabama, we do not have to deal with snow, but this year it was a roller coaster of temperatures and heavy rains. I had concerns about the azaleas that bloomed earlier than normal right before temperatures plunged. The larger ones were okay, the smaller ones, loss every bloom and look sad right now. I will pass this on to my family living in NJ, though. Great detail and loved the pictures. Happy Spring!
Thanks Ann! We use old bedsheets (wire arches over the strawberry bed and plant supports) and clothespins to cover our plants, and in the vegetable garden we use Season Extender covers from Gardeners Supply.
We actually have Cilantro, Parsley and Swiss Chard all year long using the Season Extenders here in Virginia. This year we are going for growing baby lettuces all through the winter.
Old sheets are a great choice too since plastic will burn the tender plants after the sun comes up and left on too long. I learned that the hard way. Wise words from a Master Gardener once said, “It’s like putting a glass of water in the freezer with a sock over it”. Referring to covering your plants if the temps go below 29 degrees. Made since.
I used sheets and clothes pins on peony growing rings, a tablecloth on Bleeding Hearts with a bamboo stake to hold it up, and even a big towel clipped in the trellis over my clematis. Took covers off during the day, dried cloth in dryer and put back toward night! Work, but so worth it!
I too live in Ohio, just south of Cleveland. We had over five inches of that heavy snow. My peonies were up only a few inches, bit the hydrangeas were fairly well leafed out with tiny leaves. Got the burlap back out and recovered them. I was worried about mt clematis as it was new and had come up about six inches. Took straw and covered it. There was snow, but apparently was secluded enough the snow didn’t break off any of the tender shoots.
So happy now our plants might get to grow and bring us joy, but who knows, we do live in Ohio. 🙂
My Pawpaw used tomato cages. Here in the south…when it snows, it is a strange day or two. You use what you have.
We, too, had 6″ of snow here in Western New York on Wednesday. While nothing in my yard is anywhere near ready to bloom I was only concerned about the 2 cherry trees in my front yard. They are technically property of the town, but we have the only ones on our large circular street and everyone looks forward to the beautiful cherry blossoms. Several times they have been hit by frost and the blossoms killed. I think they may have survived the heavy wet snow because we didn’t have a really “hard freeze”.
One time in 1996 my ex husband and I had just planted a large perennial garden along the side of our property. We no sooner got done planting several varieties of young plants and trees and a neighbor told us we were going to have frost. He offered the aisle runner they had saved from his daughter’s wedding. It was perfect. Lightweight and large enough to cover the entire area. What a life saver!
We are also in Ohio and I did the same thing but used water bottles as weights since I didn’t have anything larger and heavy enough. We attacked our recycling bin and filled jugs and water bottles and it worked like a charm. I think I “may” have lost one pot of flowers that had bloomed early but if that is all I am one happy Ohioan. So far everything else looks great and now we embrace the other extreme as we are to hit 80 this week. Oh Ohio and her major mood swings! :)
Love the idea of filling water jugs and bottles. Thank you so much for sharing!
Thank you Ann – gotta love springtime in the north!
