Joe’s Journal, Winter Edition: A Year-Round Seed Starting Schedule
I have found that creating a system of organization for seed starting helps not only with timely sowing, but with time management. First start with listing the plants that you wish to grow. Greens generally like cooler growing temperatures: these are ideal for spring and fall sowing. Fruit bearing crops generally prefer warm temps and a long growing season. This latter group ought to be started indoors, well before the last frost date. Once you’ve organized what you want to grow, you can create a schedule for yourself. What follows is the list of veg and flowering plants that we are growing on our farming plots.
Additional information you will need to know:
- Average last frost date
- Average first frost date
- Number of days to harvest for your crop
You can easily get this information online. For example, in our area (western North Carolina) there is only a 10% chance of overnight temperatures of 36 F by May 14th, so I’ll wait until then to put out tender crops. However, cool season crops can be planted in spring as soon as the ground can be worked. In our area, we can plant as early as April 18th. We have an 80% chance of having 32 F by October 30th.
Having this information, can help you plan and increase the probability of successful harvests. For example, our warm weather growing season, based on these data, is 175 days long. Our cool weather growing season is 203 days long.
To maximize planting success, we stagger our spring sowing dates every two weeks. This not only protects your crop, but also minimizes your workload!
The number of days to harvest for a cross-section of crops we’re planning:
- Swiss Chard: 28-42 days
- Mesclun Greens: 30-40 days
- Sugar Snap Peas: 42-56 days
- Beets, Cylindra: 55-65 days
- Tomato, Black Strawberry: 60 days
- Runner Beans, Blauhilde: 65 days
- Bush beans, Anellino di Trento: 60-75 days
- Sugar Rush Peach Pepper: 60-80 days
- Carrots, Black Nebula: 75-80 days
- Tomato, Indigo Blue Chocolate: 80 days
- Cherokee Purple Tomatoes: 80-90 days
- Candy Roaster Squash: 100 days
- Connecticut Field Pumpkin: 110 days
Consider growing short season crops (that are harvested in 60-80 days), both spring and fall. Sow cool season crops spring or fall. No matter where you live, you can grow year-round, indoors. When days grow shorter and cooler, consider shifting your grow to indoor hydroponics. If you incorporate indoor growing, you can potentially harvest crops year-round (more on that in a future post)!
Cool weather crops to plant spring or fall
Except for the root forming crops (beets, carrots, radishes), these crops lend themselves to indoor hydroponic culture. Some members of the Apiaceae (Umbels) such as parsley and carrots benefit from pre-soaking for 24 hours prior to sowing. Cole crops (broccoli, kale, Brussels sprouts, cabbage) are magnets to caterpillars including the imported cabbage -worm and cabbage looper. When growing out-of-doors, treat young plants with a protective application of BT (Bacillus thuringiensis) or Azadirachtin.

Warm Weather Crops to Start Indoors
Start these crops as early as February or March, depending on when you plan on setting your plants out. This group of plants benefit from bottom heat and even moisture. Placing a plate glass or clear plastic over the planted seed will increase germination success. Keep an eye out for tomato or tobacco hornworms, which can strip your plants clean of foliage just when they are getting well established. Make applications of BT or Azadirachtin to solanaceous crops (tomatoes, peppers, pepino melon, potatoes, and eggplants).

Warm Weather Crops for Direct Sowing
These crops are directly sown in the garden or field. This is the simplest and easiest way to garden. Watch for Mexican bean beetle on your bean plants, which will skeletonize the developing leaves. For bean beetles, make an application of pyrethrum. Look out for wilting on winter squash vines, indicative of squash vine borer. Treat early, after the vines put out their first true leaves. Use BT or an Azadirachtin such as AzaSol to protect squash vines.

The calendar is designed for a continuous harvest. Of course, grow what you like! For instance, you may want to include potatoes, sweet potatoes, onions, and garlic in your garden plan. The amount to grow is based on your time and available space, and what you prefer eating. Gardens are as individual as the gardener tending it: So, go for it! And above all, have fun!
