How to Winterize Lavender in 3 Simple Steps — Protect Your Blooms From Frost for an Aromatic Garden Next Year

Lavender is probably one of the most common herb garden plants around. With its low-maintenance tendencies, all-around hardiness, scintillating scent, and stunning vibrant foliage, there's no doubt why this crop is a green-thumb favorite.

But as winter creeps up on them, these purple herbs typically benefit from a touch of plant protection by overwintering. Not all garden crops need to be winterized, but to neglect lavender at this time of year would be a rookie mistake.

Whether your lavender is sitting pretty in pots or growing in bushels out of the ground, it's a good idea to take note of the winterizing process and add this garden chore to your to-do list. After all, you don't want one cold snap to void your efforts in growing this lovely herb.

How to Winterize Lavender

We find that winter shielding is an essential aspect of lavender plant care and gardening expert Tony O'Neill agrees. To familiarize us with winterizing lavender 101, he has provided us with his go-to guide to keeping lavender safe through the frost.

Step 1: "Around late summer or early fall, trim back about one-third of the plant’s foliage," says Tony. "This will help to maintain its shape and remove spent flowers."

Step 2: Next, he recommends adding a layer of mulch around the base of the lavender to help insulate the roots and protect them from freezing temperatures. "Use straw or shredded bark," he adds. "But avoid placing it directly on the stems."

Step 3: In regions where temperatures drop below freezing frequently, he finds covering the plants to be a smart move. "Use a frost cloth or breathable plant cover to shield the lavender from harsh conditions," he advises.

As a fairly easy three-step process, we sincerely encourage gardeners to adopt the winterizing method to support lavender gardens over the course of the colder months to come.

When to Winterize Lavender

According to Tony, the ideal time to winterize lavender is in the fall. Usually, he finds that this technique is most beneficial when administered by late September to early October, depending on your region's climate.

"You should begin winterizing once the risk of heavy frost is near, and the plant is no longer actively growing," notes Tony. Proper winterizing will save you from having to revive lavender post-winter.

How to Winterize Potted Lavender

If you've been planting lavender in containers and are curious about how to defend them from the cold, we've got you covered. Tony tells us that these three tips are perfect for winterizing potted lavender and have helped his container garden through many a cold snap.

Tip 1: "Lavender in pots should be relocated to a sheltered space," says Tony. He recommends relocating them to a porch, greenhouse, or even indoors. Essentially, he finds it best to store it in an area where it won’t be exposed to freezing winds or harsh winter conditions.

Tip 2: According to him, adjusting your watering routine is another brilliant tip to acclimate your crops. "Water sparingly throughout winter, as lavender doesn’t like to be soggy," he notes. "And make sure the soil is dry between watering."

Tip 3: He also tells us that insulating the pot is a great help. "If you can’t bring the lavender indoors, wrap the pot with bubble wrap or cloth," he says. "This will provide insulation and prevent the roots from freezing."

Lavender is an incredibly rewarding garden edition and so preparing it for the winter is one small chore that'll help your herb flourish after the frost ends. And considering the fact that winterizing them is such a straight-forward process, we see no reason as to why it should not be on all of our garden housekeeping lists for fall.

Trust us, it might seem like yet another task now but your herbs will be thanking you as the warmth returns and the crop starts to thrive again.

FAQs

Should You Cut Back Lavender for Winter?

Different types of lavender have varied needs but one of the main things they have in common is their need for pruning. Tony affirms that it's definitely a good idea to cut back lavender before winter. He explains that pruning helps the plant maintain its shape and prevents it from becoming too leggy.

He tells us that by cutting back spent flowers and excess foliage, you also reduce the risk of the plant becoming too heavy and susceptible to breaking under snow or frost.

Can You Prune Lavender in October?

"Yes, you can prune lavender in October," says Tony. "But make sure to avoid a heavy prune too late in the season, as this could expose the plant to damage from frost."

He tells us that a light trim in early to mid-October works well, but any heavy pruning should be done by late summer to give the plant time to recover before winter.
