Nectarine trees used to be reserved for only the warmest climates, but lately, they’ve been making a huge splash in home gardens all over the country. Since our winters can get pretty chilly, the secret to success is picking a variety that’s tough enough to handle the frost.
Where Nectarine Trees Come From
Nectarines naturally love soaking up the sun. Most of the ones you see in stores come from warm spots like Greece, Spain, France, Chile, or right here in the sunny parts of the USA.
Different Varieties, Different Cold Tolerance
Because of their Mediterranean roots, nectarines definitely prefer warmer weather. However, some varieties are surprisingly hardy and can thrive even in cooler zones. When you’re shopping for your tree, make sure to double-check the specific variety to ensure it can stand up to your local winter temperatures.
The Perfect Spot for Your Nectarine Tree
Even if you pick a hardy variety, giving your tree the right home makes a world of difference. When you plant your tree, look for a sheltered spot. A south-facing wall is perfect because it acts like a heat sink, keeping your tree cozy and protected from harsh winds.
Mulch: Your Tree’s Winter Blanket
In the fall, give your nectarine tree a little extra TLC by spreading a thick layer of mulch around the base. This doesn’t just protect the roots from ground frost; it also helps keep the moisture levels balanced. Great options for mulching include:
- Bark mulch
- Fallen leaves
- Brush or twigs
- Humus
- Grass clippings
Watch Out for Late Frosts
The real danger for nectarines isn’t just mid-winter—it’s those sneaky late-spring frosts. If the blossoms have already opened, a sudden freeze can damage them, which means you won’t get any fruit that year. The time between the buds opening and pollination is when the tree is most vulnerable.
If your tree is already blooming and the forecast calls for a freeze, grab some garden fleece or a burlap sack to cover it up. This simple step can save your entire harvest!
Extra Care for Potted Nectarine Trees
If you’re growing your nectarine tree in a container, it needs a bit more help. Since there isn’t much soil to insulate the roots, they can freeze much faster than trees in the ground. Ideally, move the pot to a frost-free winter shelter like a garage, a sunroom, or a garden shed.
If the pot has to stay outside, wrap the tree in winter fleece or burlap. Make sure to place the pot on an insulating base—like wood or Styrofoam—and tuck it against a warm wall or under a roof overhang to keep it out of the elements.
