Winter Sow Your Vegetable Seeds!
Winter Sow your Vegetable Seeds!
First off, if you are unfamiliar with the basics of winter sowing, you may want to start with the Winter Sowing 101 article, then come back for the vegetable sowing specifics.
Common Reasons for Winter Sowing Failures
Winter Sowing Failures and Reasons
Winter sowing has become one of my favorite ways to grow plants. It's also becoming more and more popular because it's easy and it works!
But, if you’ve read the Winter Sowing 101 guide and tried the winter sowing method but had some failures, the reasons for your lackluster results are probably listed below, along with ways to help ensure future success.

A common reason is bad seeds. Simple enough, right?If you had very little or no germination at all, it could be as simple as old seeds.
A Little Bit About Traded Seeds
For years I tried to save money by trading seeds on the internet and locally. Trading seeds will save you money, but you really don’t know that those seeds are actually the type of seed marked on the packet, how old the seeds are or how the package of seeds has been stored.
If you’re growing flowers from seed, having a germination failure from old or traded seeds is not a really big issue as you probably have time to reseed. But if you’re trying to grow a food crop from bad/old seed, you could lose an entire growing season of that crop by the time you realize there's a problem.
I recommend that you spend the money and buy your food crop seeds from a reputable seed supplier. There are several big names that will pop up on an internet search.
A Bit about Sow Times
There’s really only a few things to remember about when to sow the seeds and put them outside in their winter sowing containers.
Seeds of annual warm-season plants are generally sown four weeks before your average last frost date. Sowing them a lot earlier increases your odds of the seeds sitting in the containers longer than they need to and rotting from excessive moisture.
Some seeds, like most hardy perennials and cold weather crops, need a period of cold stratification, and that's why these seeds are sown and placed outside a few months earlier than the others. This "cold stratification" helps the seeds to slowly break dormancy and initiate the germination process when the weather is right.

Conditions Aren't Right For Germination Yet
It's important to remember that different seeds of plant types will germinate at different times as the seeds are waiting for the right conditions.
For instance, seeds of cold hardy plants need the cooler temperatures and will generally germinate before seeds of warm weather plants.
If the seeds haven't germinated when you expected, it may just be a case of waiting a few weeks longer for the seed to get the right conditions to germinate. Don't give up too soon. Many winter sowers, including myself, have chucked a winter sown container only to find out that the seeds did germinate later.

Seedlings Germinated then Died
Excess water not only can rot the seeds as they wait to germinate, but can kill seedlings once they’re up. Having an adequate amount of drainage holes in the bottom of the winter sown container is very important.
For a milk jug container, I put at least five to six drainage holes in the bottom. If you’re using a knife to cut slits for drainage, I would double that. More is better.

If the containers were placed for the winter in an area where excessive rainfall has fallen on them, like under house eves, (I've done that), that extra rain could rot what's inside.
Also, if the containers were placed directly on soil, the soil underneath may have eventually clogged the drainage holes. I place my winter sown containers on top of a graveled area for extra drainage.
Late Frosts
If there's a late frost after the seedlings are up,
throw a blanket or like item over the containers and take it off in the morning. Winter sown seedlings are relatively hardy since they are already somewhat acclimated to the outside weather, however, they are still only seedlings, and big swings in temperature will necessitate the extra care.
Excess Heat
The same winter sown enclosures that keep the soil and seedlings warmer in cold weather will also allow the containers to keep in the sun's warmth, and an unusually hot, sunny day can literally fry young seedlings.
Placing the containers facing south will give the containers a bit of an edge against really harsh winters. Once the weather begins to warm and the sun becomes stronger, moving the containers to an area with less direct sun is recommended.
Soil Dried Out
The lids of the containers are left off for the sole purpose of letting moisture in during the winter or colder weather. But once the seedlings are up and the weather warms and rainfall decreases, it’s necessary to check on the soil every few days just to make sure it hasn’t completely dried out. A good spritz of water on the top of the soil may be enough.
In drier conditions you may need to water the soil well, and bottom watering the containers is the best way to do that. Just set the containers in a tub of a few inches of water, maybe a kids' pool, and let the soil drink up what it needs. Make sure you take the containers out once the soil is saturated.
Lack of Nutrition
Spring is a very busy time in the garden, and sometimes my winter sown seedlings or plants don't get planted as early as I would like.
If you notice that some leaves on the seedlings are yellowing, a shot of diluted balanced fertilizer at 1/4 strength can give them the shot they need to remain healthy. This is even more important if you had used a soil mix in the containers that did not contain any fertilizer.
I use a regular potting soil that contains a small amount of fertilizer, and that is usually enough to sustain the seedlings until transplant.
Seedlings Die After Transplanting
Even though winter sown seedlings are already much hardier than those grown inside under grow lights which need to be hardened off, they will still need more care until they are well established in their final destination.

If in doubt that the seedlings are strong enough to transplant out into the garden, let them grow in the container a bit longer. And when you do transplant the seedlings, shade them for a few days with a tented piece of cardboard or the like as you would with any transplant.
If you have more seedlings than you really need and they've grown together in a hunk, instead of disturbing the roots and planting them separately, you can transplant a hunk of seedlings together and let the hardiest survive.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So there’s my top reasons for why you may have gotten less than stellar results from your winter sowing attempt.

Growing Sage - Homesteading 101
GROWING SAGE
Perennial Zones 4 – 8 (Hardiness Varies)
Sage is a shrubby perennial that’s an obvious choice for the kitchen. From spring through mid-summer, Sage displays blue to lavender flowers which are very attractive to birds. It has an earthy, rich, spicy flavor and it is part of the mint family.
The most popular types of culinary Sage are Garden Sage, Golden Garden Sage, Berggarten Garden Sage, Dwarf Garden Sage, Tricolor Garden Sage, and Window Box Sage.
Starting Sage from Seed
Seed Longevity: 2 years.
Seed Sowing Depth: Surface, cover lightly.
Best Soil Temp for Germination: 65 – 70 degrees.
Days to Germination: 15-21 days.
Spring Sowing:
Sow Indoors 6 – 8 weeks before the last frost. Transplant out after the last frost date.
Fall: Not recommended.
Winter Sowing
For our article containing detailed information about Winter Sowing, see our separate article.
Growing Sage
Plant Size: 1-3’ Height.
Growing Soil Temperature: 55 – 80 degrees.
Spacing: 12 - 18”.
Container Size: 12” x 12” good size for Sage.
Soil: Well-drained.
Watering: Light, only during dry spells. Avoid overwatering.
Light/Sun: Full sun to light shade.
Fertilizer: Add some compost throughout the year.
Other Care Tips:
- Prefers cool to warm temperatures and will need some shade during the hot weather.
- The plant should be replaced every 4-5 years.
- Remove flower spikes before they have a chance to flower.
- After three years, trim off woody parts to encourage new growth.
Dividing Sage
Best to divide Sage every 4-5 years when the plant becomes woody. Dig up the entire plant, and using a sharp shovel, divide it into sections. Remove all woody parts and replant the tender sections planting at the same depth.
Softwood Cuttings of Sage
Take cuttings in spring when new growth is several inches in length. Side shoots of 4" in length are perfect. Cut the stem at an angle and remove lower leaves leaving an inch or two of the stem bare. Plant cutting bare side down into a well-drained soil mix. No fertilizer is needed at this stage.
Wrap the container in plastic to keep in humidity. Avoid having the leaves touch the plastic. Place the pot in light but out of direct light. Keep soil moist but never soggy. Remove the plastic when cutting grows roots. A light tug that gives you some resistance means it has rooted.
Harvesting Sage
Start to harvest Sage once you see good growth on the plant. Best harvested when tops of blossoms are barely open. You can gather leaves at any time. Sage is most flavorful as flowers begin to open. Purple-leaved Sage tends to be more aromatic than green-leaved Sage.
Storing Sage
Fresh
Damp Paper Towel
This method works well for hardy herbs that have woody stems as well as a few soft-stemmed herbs.
Clean and thoroughly dry the Sage. Arrange lengthwise in a single layer on a slightly damp paper towel. Loosely roll up the herb and transfer to a plastic bag or plastic wrap. Label and store in the fridge. Sage will stay fresh in the fridge using this method for up to 2 weeks.
Freezing
For best results, use frozen Sage within 1-2 years. By freezing herbs, you will lose some of the herb's texture but preserve the flavor. Here are a few freezing options to consider:
Tray Freeze
Strip leaves off the stems of the Sage and spread onto a cookie sheet on a single layer. Freeze in the freezer, then place it in a labeled freezer bag to store. Since the leaves are frozen separately, you can easily remove the amount you need.
Ice Cube Trays with Oil
This method works well for hard-stemmed herbs that would probably be cooked when adding to a dish. The oil reduces some of the browning and freezer burns.
Clean and thoroughly dry herbs. Mince and firmly pack herbs into an ice cube tray 3/4 full. Add Olive Oil to fill and freeze. Transfer frozen cubes into labeled freezer bags to store.
Flat Freezer Bag
Trim off the stems and place them in a labeled freezer bag. Squeeze out the air, flatten the freezer bag, label and store.
Drying
Sage contains more oil than most other herbs so it dries more slowly. It is one of the best herbs to dry. For best results, use dried Sage within 1-2 years.
Hang to Dry
Pick your Sage in bunches right before you intend to store them. Tie the bottom of the bunch together with twine and hang upside down to dry in a dry, low humidity area. For added protection against dust, you can put the bundles inside paper bags with plenty of holes for ventilation. When the herbs are dry, the leaves will crumble easily between your fingers. Store in an airtight container.
Using Sage
- Sage can be overwhelming so start with small amounts.
- Use leaves fresh in recipes or add them sparingly to salads.
- Dried sage is commonly used with Thanksgiving stuffing.
- It can be paired with pork, beans, potatoes, and cheese.
- You can mix it into a soft cheese for a tasty bread spread.

Winter Sowing
If you haven't tried winter sowing, you're in for a treat. This method is especially good for sowing herbs. Winter sowing is basically sowing seeds in the bottom of a milk jug in the winter, setting the milk jugs outside for the winter and leaving them there until the seeds germinate in the Spring.For a detailed blog about Winter Sowing, click here.
Other Sowing Tips
- Cilantro reseeds easily, so give it a place in your garden to do so.
- Cilantro will bolt quickly in hot weather.

Growing Cilantro
Plant Size: Height 18-24" Width to 18"
Soil Temperature: 50 - 75 degrees.
Spacing in Beds: 6-8"
Container Size: 8-10" deep and 18" wide
Soil: Well draining.
Watering: Dry soil causes the plant to bolt.
Light/Sun: For seeds, full sun. For leaves, light shade.
Fertilizer: Avoid fertilizer if growing for seed since that may actually delay
flowering.
Other Care Tips
- For a continuous supply, make succession sowings every three weeks.
- Snip off the top part of the main stem as soon as it develops flower buds or seed pods.
Harvesting Cilantro Leaves
Leaves can be cut at any time. Use the upper newly-cut leaves for cooking.
Harvesting Coriander Seeds
Harvest large seeds on a dry day. Cut off the top of stems when the seed pods begin to turn brown and crack if pressed. Place seed pods in a paper bag and let dry. Pods can be rolled around in between your fingers to release the seeds.
Storing Cilantro
Fresh
Bouquet Storage
This method works well for tender herbs with soft stems and leaves.
Clean and thoroughly dry the Cilantro. Trim the ends of the stems and remove any wilted or browned leaves. Place Cilantro in a Mason jar or clear glass with 1" of water like a bouquet of flowers. Loosely cover with a plastic bag or cling wrap. Label and store in the fridge.
Cilantro will stay fresh in the fridge with this method for up to 3 weeks.
Freezing
For best results, use frozen Cilantro within 1 to 2 years. By freezing herbs, you will lose some of the herb's texture but preserve the flavor.
Here are some methods for freezing:
Tray Freeze
Spread the Cilantro onto a cookie sheet on a single layer. Freeze in the freezer, then transfer the herbs into a labeled freezer bag to store. Since the leaves are frozen separately, you can easily remove the amount you need.Ice Cube Trays
