Start Your Own Tomatoes and Peppers from Seed in January — Native Nurseries (2024)

A few years ago, I planted pepper seeds for the first time to make my own paprika. This small start sent me on a journey from my bathroom window to a small growing tent in my closet and eventually to some of the best and most interesting paprika I have ever tasted.

Peppers and tomatoes are both members of the nightshade family. In our area they have similar growing habits and time frames for planting. The timing of seed planting is one of the most important aspects of growing vegetables. Other considerations include available equipment, quantity of plants needed, and the planting and caring of the seeds and seedlings.

When choosing a pepper or tomato to grow from seed, consider how you are planning to use the produce. For instance, if you enjoy pasta with red sauce, a determinate Roma-style tomato might be the best choice. For hot sauces, I have enjoyed some of the super-hot peppers, although one plant is often enough! Sharing or exchanging your extra plants with friends is often an option to gain a diversity of varieties after you have too many plants. If growing a whole seed packet of one variety, I usually have a project in mind that requires lots of the same variety of pepper or tomato.

The equipment needed for starting peppers and tomatoes consists of a heat mat, grow light, containers to start the seeds in, watering can, fertilizer and growing medium. Tomatoes do not need as much heat to germinate as a lot of the peppers. It is possible to grow both in a south facing window or greenhouse but without sufficient light and heat the peppers will be very slow to grow. Peppers prefer to be germinated between 70-90 degrees Fahrenheit, while tomatoes prefer 65-85 degrees. My house is usually under 70 in the winter, so I run a heat mat to keep the soil temperature closer to 80 degrees. This is the same with the lighting situation, which requires me to use a grow light to get sufficient light to the seedlings.

You can use a good quality potting soil or seed starting mix as your growing medium. Your container could be a nursery flat with individual cells or small 2-inch pots. Here is my recipe for sowing the seed:

1. Fill the seed starting flat or individual pots with seed starter mix

2. Place 3-4 seeds per cell or pot

3. Gently sprinkle worm castings to cover seeds (or use more of potting medium)

4. Press down to achieve good seed to soil contact

5. Water lightly using a watering can with a fine shower or water from the bottom to keep disturbance to a minimum.

The seeds will usually germinate in 5-to-10-days, but some peppers in low temperatures can take a few weeks so don’t toss empty containers immediately. During this time, keep the top portion of the container moist. During germination the cotyledon will emerge, followed by the first set of true leaves. Make sure the seeds and plants are getting plenty of light, 14-16 hours. A window will only get a few hours when compared to a grow light. Select the strongest seedling in each cell or pot and cut out the others. At this point the plant can be fertilized with Neptune’s Harvest or other fish/seaweed product which is gentle and promotes a great burst of growth. Continue to water thoroughly and fertilizer once a week.

The best time to plant both the seeds of peppers and tomatoes is in January. Tomato seedlings can be planted outside in late February, then protected from frost, while peppers prefer a warmer temperature and should be planted outside after the last frost, usually in late March or April.

Many of the peppers are slow to grow while tomatoes shoot up very fast. Each growing season will be different and will present different challenges, but the final product is delicious and well worth the effort.

FAQs

Can I start tomato seeds in January? ›

The best time to plant both the seeds of peppers and tomatoes is in January. Tomato seedlings can be planted outside in late February, then protected from frost, while peppers prefer a warmer temperature and should be planted outside after the last frost, usually in late March or April.

When to start native plant seeds? ›

Native seeds, unlike vegetable seeds, don't want to be sown in your house under lights or in a greenhouse. They don't want to be sown outdoors in late spring either. They germinate best when they are sown outdoors in late fall.

When should I start tomato and pepper seeds indoors? ›

Generally, the time to start your seeds is about 6- 8 weeks before the last expected spring frost date in your area, planting the seedlings outdoors about 2 weeks after that date.

How long does it take for tomato and pepper seeds to sprout? ›

You should see germination within 2 to 3 weeks if it's warm enough. I strongly suggest using bottom heat to achieve the warmth the seeds need – most good nurseries carry good little electric seed starting mats which will keep your seeds at the right temperature to sprout.

Is January too early to start seeds? ›

Even if the last thing you're thinking about in January or February is the garden, it's actually a great time to start seeds indoors for frost-hardy leafy greens and for slow-to-get-started herbs.

How late is too late to start tomato seeds? ›

Definitely not. You can plant tomato seeds anytime in the spring. Many people around here don't sow them until April, as they are fast germinators and fast growers. We find they do even better when they are planted in the ground when they're younger (after it warms up and all chance of frost has passed, of course).

Do native plant seeds need cold stratification? ›

Many native varieties, like Prairie Coneflower, require cold stratification if seeding in spring. The good news is this is an easy process for any gardener.

What is the easiest native tree to grow from seed? ›

Acorns and Oaks are easy to fnd. Pine Cones from Evergreens are easy enough to find also. Just about anything you want to grow can be started from seed as long as its not a grafted plant. If it is a graft the seed will revert to a parent plant if it is even viable at all.

What month should I start my seeds indoors? ›

Planting seeds is also a great way to grow specific varieties. March is a great time to start seedlings indoors. Generally, start planting seeds indoors 6-10 weeks before the last frost date.

Can you start tomatoes indoors in February? ›

So, start seeds indoors in early to mid-March. Zone 6: Here, the last frost is typically around mid-April. Hence, late February to early March is a good time to start. Zone 8: With an earlier last frost date in late February or early March, you should start seeds in early to mid-January.

Should I soak tomato seeds before planting? ›

The technique is proven by biological scientist. During the study the tomato seeds were soaked for 12, 24 and 36 hours, and the best results were achieved after a 24 hour soak. So if you have older seeds or you late with the sowings then you can just soak the tomato seeds in water for a day to speed up the germination.

What is the best month to start tomato seeds? ›

Sow tomato seeds in warm conditions, into modules, small pots or seed trays. Tomatoes are easy to grow from seed indoors. Sow from late February to mid-March if you'll be growing your crop in a greenhouse, or from late March to early April if they'll be outside.

What grows faster, tomatoes or peppers? ›

In my experience, it's very normal for peppers to grow more slowly than tomatoes and especially squash (squash can grow fast).

Will tomato seeds germinate at 65 degrees? ›

For example, the optimum temperature range for tomatoes is 65° to 85°F (see previous chart). Within that range, it takes approximately 6 to 8 days before seeds germinate. Tomato seeds may still germinate at 50°F, but it will take over 40 days, and there will probably be no germination if the soil temperature is 104°F.

Should I soak pepper seeds before planting? ›

While not necessary, you can soak pepper seeds prior to planting them to encourage faster germination. Place pepper seeds in a bowl or jar of room temperature water for up to 24 hours to soften the seed coat and break dormancy.

What month should I start my tomato seeds? ›

So if your expected last frost date is May 10, for example, count back at least six weeks to March 29 as the day you need to get your tomato seeds planted. This will give the seedlings enough time to grow sufficient roots and leaves to establish quickly when planted out in your garden.

How cold is too cold for tomato seeds? ›

How Cold Can Tomatoes Tolerate? Tomato seeds won't germinate when the soil temperature is below 50 degrees Fahrenheit. Tomato seedlings suffer cold damage in temperatures below 60 degrees Fahrenheit. Some tomato varieties are bred to be more cold-tolerant and can set fruit when it's below 55 degrees Fahrenheit.

Can I start tomatoes in February? ›

For cooler areas, February is a great time to sow your tomatoes and peppers. You should start drawing out your garden for all the vegetables you want to grow. In late February, there are several cool weather vegetables you can directly sow out in the garden.

Will tomato seeds germinate after freezing? ›

With bad luck NONE will germinate. Tomato seeds must be very very low moisture to survive the freezer. However, we all get a few outdoors to germinate in the spring from the tomatoes that sat on the ground over winter.
