Over Wintering Your Herbs

I am published in Fine Gardening magazine…

It all started with questions I was getting from customers about growing outdoor herbs in the winter. Because we strive to provide an exchange of information for all types of growers, I was more than happy to help. Fine Gardening was getting the same questions from their readers that we were getting from our customers, so they picked up my article and used it in their December 2012 edition to help reach more growers who were having the same questions.


A Strategy for Maintaining Fresh Herbs in Winter

Here are a few tips to help you winter over your favorite herbs:

3 reasons to bring your herbs indoors:

  1. Keep the herbs alive to get more months of enjoyment
  2. Enjoy fresh flavor for all of your hearty winter dishes.
  3. To keep tender plants over-winter for spring planting

When to bring herbs indoors: Two weeks before the first hard frost, typically mid-Sept to mid-October


How to repot:

  • Choose the healthiest plants and compost the others.
  • Clean soil of debris and weeds
  • Dig plants carefully, saving a generous root ball.
  • Repot into containers 2” wider and deeper than the root ball using fresh potting soil
  • Thoroughly water newly potted plants
  • Leave plants outside for a few days to acclimate to their new containers.

Indoor Care Tips:

  • Choose a sunny location with 6-8 hours of direct sun.
  • Consider temperature and humidity. Don’t place them where they will dry out quickly or be in a cold, drafty spot.
  • Typically herbs don’t need a lot of water. Check soil by sticking your finger about a half inch in to test for moisture.
  • Room temp should not go below 50 degrees
  • Let the plants rest before harvesting
  • Don’t be alarmed if your herb plants lose their lower leaves as this is the plant’s way of dealing with the change and getting rid of leaves that no longer produce enough food. Lemon Verbena is especially likely to do this.

Which herbs will work best indoors?

  • Tender perennials: Bay, Lemon Verbena, Lemon Grass
  • Biennial herbs: parsley
  • Annual herbs: cilantro, arugula,

Dormancy requirements make some plants better choices.

  • Unless you want to add grow lights, avoid plants that go dormant like mint
  • Hardy perennials are best left outdoors. Rosemary, Lavender, Mint

Replanting your herbs for Spring:

After the last frost, usually late April or early May, start placing potted herbs outside during the day so they get accustomed to a new climate. Keep an eye on night temperatures. Begin to leave them out when night temperatures are above 50F.

  • Plants should have been pruned in winter. Trim stray stems to keep plants bushy
  • Replant in mid-May








Is Chamomile a Weed?

Chamomile a weed? One person’s weed is another person’s herb!

While on a trip to Prairie Canada, I was surprised to find find common chamomile blooming among the prairie plants. After first spotting this familiar herb, I began seeing it along the road shoulder, in fields of peas and beans, and even in the lawn where I was staying. From my host, I learned that on the prairie farmers consider chamomile a noxious weed and work hard trying to eliminate it from their crops fields.  This is a good example for comparing a desirable herb plant from a weed. And as the description for weeds explains; it all depends on where a plant is growing! So even though chamomile is a weed is some places, it is a welcome herb in my garden. I have plenty of other plants on my own weed list!

Varmints in the Garden

I never thought our Year in the Life of a Garden would be raided by varmints, but it was last night. I cannot tell what it was that dug into a row of Pak Choi seedlings and buried some Arugula with their tailings. Damage was slight and what ever came rooting around did not find much of interest in our salad bed. My guess is that it was a raccoon or opossum attracted by the kelp meal fertilizer. Maybe it is better not to use fish fertilizer, as that will surely bring curious diggers.

Another little lesson we have learned in this spring garden in that using old seeds is risky. We sowed extra because the seeds were two years old, but none of the Spicy Mesculin Mix lettuce seeds germinated. Today I sowed fresh seed into that row and we should still have plenty of time to grow lettuce for cutting. I think next I will add a few herb plants around the borders, maybe a basil plant in the center. The logs surrounding the bed are impregnated with mushroom so we hope to harvest some interesting salad makings soon!


Our New Garden

We have always wanted a place where all the plants grown in our nursery could be grown out to full size. Now that all of our time is spent working from the nursery, we found the time to dig up the yard surrounding it. Because time is always hard to find for such projects, we have been taking our time. Shrubs were planted the first year and later a waterfall was added. Now we have laid out the paths and beds on the ground and will begin preparing the beds for planting.

It may be fall before we have them ready. Not being in a hurry, we want to dig deep and work plenty of organic material into the soil. Only when the beds are finished will we begin to add herb plants and some perennial flowering plants. Piecemeal is always the way to tackle a large job, so we will finish some beds before others are started. This way we will be able to grow some of our flowering annual plants. Cut flowers like zinnias and celosia will provide fresh cut flowers for the office. We want to demonstrate all the ways our plants can be grown.

Every step will be documented: from soil and bed preparation, planning and planting, to care and harvest. Check out The Growers-Exchange.com for all of our Year in the Life of a Garden updates.

Office Garden Plan

First Seedlings Up

Looking at the salad patch this morning I was pleased to see we had a good stand of seedlings. Using a cold frame for early season protection, we get a month or more growing time over outside. The plants are also safe from wind and rain. A windy cold day outside is warm inside the cold frame. It is amazing the difference a sheet of plastic makes.

Finally I can begin to report on plant progress, not just winter preparations. Growing now we have most of what we need for a salad. Leafy greens come in all shapes and flavors so we have a good selection. Lettuces are represented by: Braising Mix, Wildfire Mix, Spicy Mesculin, and All Greens Mix. Check out the details on our site. Even though they are herb plants, I am adding Salad Burnet and Sorrel for their distinct flavors. Last but not least is Arugula for spicy greens.

The plants are growing so it will not be but a few weeks before we will be cutting and tasting these greens, spring is really here!! In the greenhouse this week we started four types of melons and two cucumbers, these will be planted in the cold frame beds when night temperatures are warmer. The plan is to train the vines to climb the cold frame bows, melons will be supported in little hammocks. Watch the garden grow, and let us know some of your gardening ideas.


First Seeds in the Ground

We are finally able to report actual planting in our “A Year in the Life of a Garden” cold frame. Today we began by helping ourselves first with a salad garden. We are growing all the lettuce varieties offered by The Growers- Exchange.com: Wildfire, Arugula, All Greens, and Spicy Mesculin. All these annual plants will be finished by June, the lettuces wilt in the early summer heat.

The night temperatures restrict us to cool season plants for now, but as spring progresses we will add a basil plant along with any other herb plants useful in cooking. Our small gardens will produce plenty to eat from our veggies and culinary herbs.

We plan to add lots of flowering annuals to compliment our herb plants. Annual vines such as Moonflower and Hyacinth Bean will climb trellises and frame our beds. We like to grow old fashion favorites like celosia. We have several varieties: the brain varieties ‘Cramers Burgundy’ and ‘Lemon Lime’ always draw attention in the garden and as a cut flower. The plume type celosia plant has an entirely different flower and makes a great filler in bouquets. I am getting ahead of myself, celosia planting time is at least a month away.

For now we will grow salad plants and a little collards, kale, and broccoli too! Soon we will begin planting example gardens for our herb gardening kits. We hope to have pictures of all growth stages, which we can post on here on the blog. Herb gardening can look like weed gardening so our challenge will be to add flowering annuals for color and texture.

Next week we will have photos of the baby salad plants! We encourage you to follow our garden and makes suggestions if you like…
