Overwintering Lavender | Quick Tips

Lavender fields are impressive, not just because of how incredible they look, but because of the feeling of calm and peace they create that is so hard to find elsewhere. That relaxing property is just one of the many reasons why we love to grow this plant at home, but lavender is also wonderful when used ornamentally. Couple this with its soothing effect and charming aroma, and you start to scratch the surface of its many, many uses.

Start with a cold-hardy cultivar if you plant to try to overwinter rosemary in the ground in other than a truly frost-free hardiness zone. ‘Arp’ is the best known, along with ‘Hill Hardy’ (also known as ‘Madalene Hill’ after the late herb gardener from Texas; ‘Arp’ was her discovery, by the way, the result of her search for plants that could take not extremes of cold but the Texas heat). Oregon-based Nichols Garden Nursery’s owner touts ‘Nichols Select’ as being a toughie, too.It’s “as hardy as any I’ve grown, probably Zone 6B, and the flavor is terrific,” Rose Marie Nichols McGee in an interview one spring. “It was planted 25 years ago at our home and survived minus-7 degrees F once. I think this is your best for a long-lived rosemary.”The U.S. National Arboretum website trialed many cultivars, and how they fare on all scores. Even in USDA Zone 7A,

Once they have dropped their leaves and gone dormant, after a good hard freeze or so, I get out the hand cart and engage a brave friend. We say our prayers, then wheel them one by one over my hilly garden, down to the unheated barn.I will certainly meet my end someday under one of these big pots, when I am manning the downhill side of this hauling operation.I make sure that they are well-watered during the fall, so that they go into storage well-hydrated—and therefore less prone to dessication while in there.  No water is offered in the coldest months, when the soil and the trees inside the building are mostly frozen, but I start checking around February, once the

I’M SEEING SHADES OF BLUE ON THE WEATHER MAP (you know, the numbing color of lips exposed to too much cold) and thinking, No, not yet; please not yet. But there it is, in living (killing?) color, on the NOAA map: time to bring in the tender things, or else.

First, my general thinking: No two gardeners’ potential places to stash such treasures will match in temperature or humidity, so when I say the basement works well here, your cellar might not. I have identified my best spots by experimenting, and by killing many things in the process. But every year I score another victory or two because I don’t let failure stop me. (Isn’t all gardening like that?)And this: If I don’t have the right spot for a plant–often a combination of high light but cool, 50ish-degree conditions–try forcing dormancy or semi-dormancy versus forcing it to limp along, suffering. If you have non-hardy plants you’ve tried keeping as “houseplants” in your heated home, only to see them go wretched and leggy, think about letting them rest, or close to it, next time. Water very sparingly and keep them as cool as possible.Extra heroics: Adding a growlight hood for 12 hours a day in, say, a cool basement could make a

IF YOU HAVEN’T even started bringing in your houseplants or are in a warmer zone, the first part of the discussion talked about taking stock of what needs storing and evaluating and prepping potential overwintering spaces at your home.  I recapped that quickly yesterday in Part 2, then got on to specifics how to store dahlias, cannas, elephant ears and more.

I AM IN DENIAL. It simply cannot be time to move over and make room for them again in here, can it? But yes, the nights are already cooler than my fancy-leaf begonias and bromeliads would like, and before long it will be colder than everybody tender will tolerate outside.

Confession: Despite all my years at “Martha Stewart Living,” Gayla is far more adventurous in making things than I am. We both cook, and can, like mad—but she goes further. After purchasing a small copper still, Gayla spent her summer making hydrosols (floral waters—such as rose water), and just bought a set of wood-carving tools to try her hand at spoons and other implements. Impressive.And she can sew—to make the oversized muslin packets for herbed bath “tea” bags, for instance. (My last attempt, in junior high school sewing class, resulted in the project becoming stitched to the lap of my dress.  The bell rang before I realized what I’d done, so I had to wear it, like a lopsided fabric collage, to my next class. Nice.)GAYLA’S RELATIONSHIP to the garden so intimate that every bit of it seems to make its way into the rest of her life, and into the lives of lucky friends who are recipients of her many giftable goodies, such as:Bundles of twiggy herbs fr

THE DISEASE THAT DETHRONED Impatiens as the top annual in the nursery industry—Impatiens Downy Mildew—continues to take its toll. But a breakthrough reminiscent of advancements we hear about in medical research was announced this month by industry giant Ball Horticultural Company.

You may recall the popular interview Kathy and I did about looking at our own gardens with a critical eye to design improvements. (If not, it’s at this link.)  We also spoke on my radio show and podcast on Oct. 13, 2014 about what to stash and how, and what to toss, just as temperature at her Massachusetts location at Avant Gardens and mine were flirting with the mid-30s at night.Plus: Links to in-depth articles by Kathy and by me on aspects of overwintering–from succulents to figs, and even if you started earlier by taking cuttings from things like coleus–are at the end of the page.overwintering q&a, with kathy traceyQ.

I’ve asked garden writer, photographer and longtime friend Ken Druse of KenDruse dot com to help me answer all your Urgent Garden Questions about overwintering tactics, which is the  topic of this month’s Q&A on my public-radio show and podcast. In a regular segment plus an overtime bonus 15 minutes, we covered lots of plants, from figs and rosemary to cannas and callas and dahlias and elephant ears, to potted trees (including citrus) and shrubs and more. After each brief discussion of a plant, I’ve also included a link to more comprehensive how-to about caring for it in the offseason.Read along as you listen to the Oct. 2, 2017 edition of my public-radio show and podcast using the player below.
