When Will The First Frost Hit My Garden?

Although there is no way to know exactly when you’ll have your first frost in autumn, you can get a good idea by visiting this site and entering your zip code. The date specified is the average date of the first frost in your area. In general, your first frost is most likely to hit within 2 weeks of that date. Get a head start to prepare your garden for the first frost before it is expected.

For last-minute preparations, be sure to watch the weather reports for frost warnings. When overnight temperatures are expected to drop below freezing, you’ll have a heads up.

If your garden is in a low lying area, it is likely to suffer a frost earlier than the high ground. This is due to cold air settling in low spots. A garden planted close to a building and on high ground will be hit by frost later in the season than the surrounding terrain.

If you are planning a new garden, consider sunny spots and raised beds next to buildings to take advantage of micro-climates that are protected from wind and frost.

Plant Cool Season Crops to Prepare Your Garden for the First Frost

In many areas, the time to plant fall crops is in late summer.  Once you know the average date of the first frost in your area you can plan ahead. Plant frost-tolerant crops a month or two in advance so they get a head start.

These plants will survive light frosts but cover to protect them from hard frosts. Frost tolerant plants that supply food late in the season include the following:

Some varieties are more frost tolerant and may be harvested much later than others. Collards can survive pretty cold temps and some varieties of kale may be harvested after several hard frosts. Read descriptions in seed catalogs for frost tolerant varieties.

Harvest Frost Tender Produce

You may cover and save heat-loving crops through a few light touches of frost, but they should be harvested or covered with a cold frame before a killing frost to prevent damage. Bring in any ripe produce such as peppers, okra, tomatoes, summer squash, green beans, winter squash, and eggplant.

Place green tomatoes on a sunny windowsill, or wrap in newspaper and store in your basement or another cool spot. Check them often and bring out to ripen on the windowsill as you need them. Make a batch of fried green tomatoes. Preserve the harvest if you can’t use it all up right away.

Although pumpkins and winter squash can handle a light frost, they won’t store well after a hard frost. Harvest, cure and store them before the temperatures drop too low.

Grow Plants Under Cover

Cool-season crops planted in a cold frame, row cover, or unheated greenhouse may be kept through the winter in some areas. In cold climates, you may need heat to keep your crops from freezing. Passive solar heating methods save energy. Use black containers filled with water to absorb heat from the sun and radiate warmth at night.

Cold frames, greenhouses, floating row covers, hot caps, and growing tunnels are all great ways to extend your growing season for a couple of weeks at the beginning and end of each season.

Frost tolerant crops that are protected in a cold frame may last all winter, provided the temperatures aren’t bitter cold. Throw a heavy blanket over the cold frame when frigid weather threatens.

Bring In Containers

Grow plants in containers and bring them inside for the winter. Peppers, tomatoes, herbs, flowers, and more can be brought in before the night time temperatures get cold. Place them in a sunny window, check and treat for insect pests, and give a light dose of fertilizer after they’ve adjusted to their winter home. Some plants will continue to produce flowers and fruits with some additional light, while others will begin new growth again in spring.

Take Cuttings

Some garden plants, such as tomatoes, may be grown from cuttings. Take cuttings and bring inside to start new plants. Dip cut ends in rooting hormone, plant in a soilless medium, and place under lights on a seedling heat mat to induce rooting. Transfer to a sunny window or grow them under bright lights.

Prepare Your Garden for the First Frost by Harvesting or Protecting Root Crops

Potatoes, beets, carrots, turnips, rutabagas, and other root crops may be overwintered in your garden if you don’t have a root cellar. The easiest solution for harvesting your roots over winter is to place bales of hay or straw directly over the unharvested row. As long as the winter is not bitter cold, you will be able to move the straw aside, dig up enough roots for a week or two, and replace the bale.

If the frost line tends to run deep in your area, you’ll want to harvest those root crops before the ground freezes. Dig crops and store in a cold storage area in a root cellar, basement, garage, unheated porch, or another area with proper storage conditions.

Make The Most Of Your Fall Harvest

When the weather reports call for frost, take a few minutes to scrounge around the garden for those last few veggies. Gather unripened winter squash and pumpkins and use them like zucchini, just peel and remove seeds if they are tough. Pick a bouquet of the last tender flowers. Bring in whatever is edible and use quickly or preserve.

Homesteaders are very busy people. Sometimes we have trouble getting out to the garden to harvest before the first hard frost. If you won’t be able to harvest the rest of your produce before a frost, throw a heavy tarp or blanket over them in the evening. Keep an eye on the weather forecast for fair warning, and do your best to at least pick the end of the most frost susceptible veggies the next day.
