Goodbye February, Hello March

What does a Piedmont/Zone 7b garden look like as the month of February comes to a close? More white than green, as the photos (taken 2/26/15) show!



Snow days, together with an enforced (left) 6-week wrist-resting period due to a diagnosis of de Quervain's Tenosynovitis, have conspired to limit my outdoor activities in February. I missed checking off most...if not all...of the items on the To Do list (as shown in this previous post). Instead, you will likely have found yours truly inside, in front of the fire, holding a steaming cup of coffee rather than a garden trowel. Still, I have continued to study seed catalogs and draw up plans for the 2015 gardens (in pencil...in my garden journal...:-).

Looking ahead to the ten-day weather forecast, it is easy to see that we are headed for warmer temps. Time to think in earnest about March!

Here's what my own "To Do in March" list looks like:


Soil: Bed and Row Preparation —

  1. Our heavy Piedmont clay soil is very wet going into March, so we'll check the soil before digging, cultivating, or tilling in any of the gardens. [Walking on wet soil will cause it to compact, but we have gone completely to raised beds and raised rows, connected in a system of wide pathways.] We'll test the moisture level in the soil the old-fashioned way: make a small ball of it in the palm — if it wads up and sticks together it is too wet; if it is fairly crumbly — we are good to go to work the soil.
  2. When we can work the soil in the row garden, we will add amendments, such as compost and leaf mold, to allow for better drainage. This will make the native clay soil more friable...to give the soil "good tilth." Tilth is the "physical condition of the soil as it relates to tillage ease, seedbed quality, easy seedling emergence, and deep root penetration." While peat moss is often recommended as an amendment, it adds to the acidity (decreasing the pH), and our soil test showed a typical Piedmont soil with a pH in the range of 5.2-5.9, which is too low to support (almost all) healthy, productive veggies. We've added line to raise the pH per our soil test report, so we won't use peat moss to negate all our efforts.
  3. Raised beds provide better drainage, so they will be workable before the row garden. Each raised bed will get 1-2 bags of compost prior to planting, along with a fluffing up to decrease compaction from the snowfall.

Veggies and Herbs — 

  1. St. Patrick's Day is the traditional time to plant English peas and potatoes. The peas will go on the fence surrounding the Block Garden, and the potatoes will go in the grow bags.
  2. We hope to be seeing the first shoots of asparagus, which is in its 5th year of production in its own bed. Last fall, we covered the bed with the compost-rich soil from the potato grow bags to help keep the crowns in place during winter heaving. We should be able to enjoy harvesting this perennial for 4-5 weeks, beginning when soil temps reach 50 degrees. While asparagus dislike sharing their space with anything else, I might add some pansies here this spring. They'll add color, and we can use the blooms in salads.
  3. Speaking of salads, it'll soon be time to seed lettuce, carrots, spinach, and beets. We will also be setting out transplants of broccoli and cabbage.
  4. Since most herbs are Mediterranean natives, it is too early to think about planting them prior to the average last date of frost (typically quoted as April 15 for our area). It is time to give the rosemary a nice haircut, and I'll check on the other perennials (sage, thyme, and oregano). I will start seeds of annuals dill and parsley indoors, and I'll move my pots of chives outside on the inevitable warm days.

Orchard and Berry Patch — 

  1. Since we haven't already done it, we will have to prune the fruit trees (including apples, pears, peaches, plum, crab apples, and a cherry), the grape vines, and the berry bushes such as blackberries. After pruning, we will spray fruit trees, berry bushes, and canes with Lime Sulfur Spray. It is organic and protects against scales, mites, and borers. It's a dormant spray, so we will have to apply before the plants begin to bud out.
  2. I have concerns about the blueberry bushes, which have swollen buds that are exposed to the current snow and freezing conditions. We had a decreased harvest in 2014 due to a very late snow and hard freeze in April (which also eliminated all fruits in the Orchard). We shall see...
Roses, Grasses, Perennials, and Shrubs —
  1. When the forsythia blooms, it's time to prune the roses, following the 5-D plan: removing dead, diseased, damaged (trim back winter-killed rose canes to one inch below blackened area), diagonal (crossing), and dinky (any canes smaller than a pencil). Then we will prune remaining canes to about a foot or two above ground level. (This does not apply to the climbing roses, which get pruned after blooming.)We will also begin to deal with pests now by applying a dormant spray, like All Seasons Horticultural Spray Oil. We will also transplant roses at this time.
  2. We will prune summer-blooming shrubs such as butterfly bushes (buddlea) and crape myrtle (although we will avoid "crape murder"!). We will wait to prune our spring-blooming shrubs (such as forsythia and azalea) until they've finished blooming so we don't cut off this year's flowers. Since we haven't pruned the azalea for 5 years and they have all grown too tall and are not blooming as well, we plan to rejuvenate them by using "severe pruning," with the electric trimmer, "whacking" the whole plant down to within 6"- 12" of the ground. It is amazing how fast shrubs will grow back following this severe pruning and they will have much better form and flowers in coming years.
  3. We will cut back the dead stems of any perennials or grasses before or as the plants put out new growth. On the lamppost in the front yard, we have a jackmanii Clematis in pruning Group 3, which blooms on new wood. They can be cut nearly to the ground just before growth begins in March before new growth begins.
That should give us plenty to do, don't you think?!
Happy hoeing!

Wrapping Up 2013

December view of Box Garden,
from Center path in Way Back
Here's a snap (left) of the Box Garden, all covered up for the recent cold weather.  You'd never guess there are carrots, beets, spinach, broccoli, collards, and lettuces under those row covers, would you? And onions...lots and lots of onions! Oh, and some garlic in the Center Square...almost forgot about that.
Turnip Greens, growing in
the Way Back Row Garden










You might also see a row of green in the middle-upper left. That's a row of Seven Tops turnip greens, which don't seem to mind the frosty temps in the least. The more frost, the better the taste! Here's a close up I took of that very productive row a few weeks ago, right:

Unless you are a gardener...or farmer...you may think that the Winter months are a time of rest and reflection; a time to relax, have another cup of coffee, and enjoy the arriving seed catalogs...far removed from the soil. You would only be partially correct.

As the year comes to a close, there are several things on our To Do list before we can put the Way Back gardens to bed:

  1. Apply dormant oils to orchard trees, berry bushes, and roses. (That's what I'm working on later today...when the temps hit 50. Remember my motto: "Between 50 and 90...no lower, no higher." In summer I say, "Noon or 90...whichever comes first." But that doesn't apply here...:-)
  2. Remove the remaining vegetation in the Kitchen Row Garden.
  3. Till up the rows in the Kitchen Row Garden.
  4. Add lime to rows and to rose garden, per Soil Test Report.
  5. Mow over and collect remaining leaves on the ground in the Way Back. Add to gardens for mulch and compost. (Mr. T actually got the leaf-mowing done a couple of days ago, so we can check this one off the list.)
To elaborate a bit...

Dormant Oils -- So called because they are applied in the dormant season (winter months in the Northern Hemisphere) before bud break in late February to mid-March (in USDA Zone 7b in the Piedmont area of NC), a more accurate name would be horticultural oils, because they can be used at other times of the season (at lesser strengths). Because there are NO leaves or buds on the plants to be sprayed, we can use the oils at full-strength, as directed on the label ("the label is the law"). The winter applications of these include "All Seasons" Dormant Oil, Copper-Sulfate, and Lime-Sulfur Oil, which we purchase in concentrated form and then mix with water in a 2-gallon pump-sprayer.

As I have said before, I try my best to use the kindest, gentlest methods of pest control possible, preferring a natural choice...although I stop short of saying that I am an "organic" gardener.

The trickiest part is getting the "environment" right: temperatures must be above 45 degrees (preferably less than 70) when sprayed; there must be no rain and/or freezing temperatures forecasted for at least 24 hours; and the wind should be negligible-to-light (less than 5 mph). Finding a day that meets all of those criteria in December is tough...but fortunately today is almost perfect to get started! Yes, we could postpone until January...but we can't wait too long because (ideally) we will want to do another spraying after 30-45 days, and that second spraying MUST be done before bud-break...which can sometimes surprise you in mid-February. Plus, we can't spray the Lime Sulfur or the Copper Sulfate at the same time as the Dormant Oil without risking vegetation damage; we have to wait 1-3 weeks...and until we have ALL the right "environmental" conditions.

A good way to remember WHEN to spray is to think in terms of Holidays: New Year's for the first spraying, Valentine's for the second. That should give you a little wiggle room for dealing with the vagaries of the weather.

Here is some great information on Dormant Oils:

Remaining vegetation -- As you have seen, we still have a good stand of turnip greens in one of the rows that we need to till (more on that in a minute), which I will harvest and cook for my "Good Luck Greens" on New Year's Day...putting the rest in the freezer. I'm the only one that eats turnip greens, so I'll have plenty to keep me busy until next Fall...no worries! My original plan was to leave the greens to "go to seed," which means they send up flower stalks...and serve as excellent attractors for the pollinators (bees, mainly) that we will need for the orchard in a couple of months. And, we still have a few okra stalks still hanging on to their roots that must go to China. All of that has to be removed so we can...

Till up the rows -- We have two main reasons for tilling up the rows in the Kitchen Row Garden: (a) to turn the soil over to expose overwintering pests, especially the squash vine borer; and (b) to add amendments like lime (per our Soil Test report) and compost (like leaves). While adopting a no-till policy is admirable, we find that a winter-till is more beneficial to our soil and our harvests. Hence, the change in plan about the greens being left to flower.

Of course, we have to wait until we have dry soil to till...and that has thus far eluded us this month. We got another 1" of rain yesterday, so it will be early January before we can check this chore off the list. Sigh. Oh well, while we are awaiting dry soil, we can catch up on a couple of things inside...by the fire...with a warm beverage in hand...

Journaling -- I have been pretty faithful in keeping my Garden Journal this year, but the Holidays played havoc with my resolve to write. I want to have a good verbal "picture" of the gardens in 2013 so that I can begin planning 2014 in earnest.  That's where the letter carrier comes in!

Perusing the arriving Seed Catalogs -- Oh yes, they are arriving daily, sometimes 2 or 3 a day...making me feel for our letter carrier. And I see that along with the usual suspects (red tomatoes, green peppers, and orange carrots), the Color Purple is becoming quite popular in the vegetative universe. Purple carrots. Purple-podded (green) peas. Purple-skinned potatoes. I kid you not.

And, we know how I love to trial new things in the gardens!

Happy hoeing!
