I know what you’re thinking: Who plants things in January?! January isn’t considered a prime planting and gardening month, but gardeners in frost-free zones know this is the perfect time for cool-season vegetables. Knowing what to plant in January is the key. In case you missed this post, What Flowers to Plant in January

If you live in an area with frost, you can always plant indoors and move your stuff outdoors as the season temperatures warm up. I highly recommend CowPots and Organic Seedling Soil for seedlings.  This way, you can plant your seeds and place the CowPots in your garden when the temperatures are correct.

It has been harder to determine the optimal time to plant outside over the last few years because the weather has changed, unlike at any other time in history. I believe regular planting zone times will have to be changed very soon due to the uncertainty of the weather. We’ve been having temps in the mid 60’s for much of December here in Utah. Records have been set for high daily temperatures multiple times during the month.

How to Start Seeds Indoors

Because most zones are still cold in January, you may have to start many of your plants indoors.

Some plants, such as tomatoes, eggplants, and peppers, require much longer growing seasons than your zone may offer. To ensure healthy growth, many gardeners start their plants indoors.

If you are new to gardening, you may not know the best way to do this. Follow the instructions below to learn how to start your seeds indoors!

Buy Your Seeds

Before you begin, you have to buy your seeds. You don’t want to buy any old seeds, however.

You want your seeds to come from a trusted source. Fresher, higher-quality seeds have a higher germination rate.

This means you’ll have more seeds sprouting, giving you a head start in growing delicious, nutritious veggies.

Pot Seeds with Seed-Starting Mix

The seed-starting mix isn’t soil. However, it provides near-perfect conditions for sprouting seeds. It does this by providing a good balance of drainage and water-holding capacity while minimizing disease.

Most garden soil is unsuitable for starting seeds because it doesn’t drain well and may contain plant disease spores. 

Use Pots with Drainage Holes

You can plant your seeds in whatever you want, as long as you poke some holes in the container to allow water to drain. Without water drainage, you can drown your plants or cause the roots to become diseased. Here are some pot ideas you can try:

Plant Your Seeds Deep Enough

One thing that many tend to do is plant their seeds too deeply. If you plant them too deeply, they won’t sprout. The rule of thumb is to plant your seeds 2-3 times as deep as the seed is wide. For example, a bean would be sewn about an inch deep.

Place Seeds in a Warm Location

After you sow your seeds, you will want to place the pots in a warm location. Some good ideas would be on the refrigerator or near a radiator. 

Keep Seed Starting Mix Moist

Your seedlings will need both air and water. Therefore, you should keep the mix moist but not completely saturated. To do this, think of a damp sponge containing air and water. 

Place Sprouts in a Bright Spot

You will want to move your seedlings to a bright or sunny location as soon as they begin to sprout. You can place them in a sunny window.

However, if you aren’t getting much sunlight, adding consistent light from supplemental fluorescent bulbs does the trick. Be sure to suspend the lights an inch or two over the plants. 

Fertilize Weekly

Once your seedlings have sprouted one or two sets of leaves, it is time to start fertilizing. Use a half-strength fertilizer. Organic fertilizers are the best choice because they provide nutrients and micronutrients your plants need to thrive. 

Make Sure You Only Have One Seedling In Each One

You may notice two or more seedlings popping up. You only want one seedling per pot. Then, choose the healthiest and strongest-looking seedlings to keep. Cut the other seedlings off in the soil and discard them. 

Planting and growing your seedlings is a fun and rewarding way to kick off the gardening season. 

How To Hand Pollinate If You Need To

Hand Pollinate Flowers

Depending on your location, being able to pollinate the plants may be an issue. You can do this by hand. All you need is a paintbrush or cotton swab (see above). If you need to hand-pollinate because you’re not seeing any fruit develop, here is something to try. You do this by removing the male blossom (male blossoms don’t have fruit behind them).

They produce pollen, leaving the center covered in pollen to collect with the brush or swab. Use a brush or swab to apply the pollen you collected to the center of the female flower. This works for squash, melons, and cucumbers every time.

  1. Linda, Thanks for the reminder. It’s time for me to do a succession planting of cool weather crops and start my tomato seeds indoors. My hoop houses make my Zone 8b area more like Zone 9b, so I can grow cool weather crops all winter long. Some of my Bok Choi plants are starting to bolt and I will allow the best to grow and bolt so I can save the seed. By this time next month I’ll be eating fresh asparagus, along with the other cool weather crops I’m currently harvesting. My snow peas have been producing like crazy since last October and will continue through April barring a disaster.

    1. Hi Ray, this is so awesome about your garden!! I forgot I was going to get some BokChoy seeds! I want to grow that so badly! It feels sogood going outside to pick fresh veggies year-round. I LOVE hearing this! Linda

  2. Linda,

    Here is is 2024 and I just harvested what will probably be the last of my tomatoes, bell and banana peppers, and chard (since we are supposed to get a hard freeze tonight and I haven’t covered anything yet). My summer plants have hung around and been productive for so long I haven’t even started my winter stuff–except for bok choi (which is bolting), peas, (which the quail and other birds got because I didn’t put up the bird netting), lettuce (which is doing nicely), and carrots (most of which were also eaten by the quail). My own fault for not getting the netting put up in time. But sometimes life interferes.

    I will cover the bok choi so it can finish off and give me fresh seeds for replanting.

    I will be planting more peas, cabbage, carrots, broccoli and other cool weather crops in a few days. Also, I’ll be starting my tomatoes and squash (inside) next week. Since my Mortgage Lifter and Gardener’s Delight tomatoes did so well I’ll plant them again from saved seeds. Same with my banana peppers, Hopi Gray Squash and Black Beauty Zucchini.

    My asparagus is already coming up so I’m getting a very early crop this year–hope it lasts.

    My apple trees have already broken bud and leafed out (not good if we get a serious freeze).

    Oh, and the chickens are all still laying despite temps down in the 30’s at night so I think the mash and crimped oats supplement to their feed is working.

    1. Hi Ray, oh my gosh, you know I love hearing about your garden! In Southern Utah we would not have tomatoes right now, you are rocking! Great tip on the supplement feed for the chickens, that’s so awesome! I can almost take the the vegetables you talk about! Man, I miss gardening! Hopefully this year!! Linda

  3. Linda,

    I’m still picking tomatoes. Tomorrow is Jan 1, 2025 and it still hasn’t got cold enough to kill my tomato plants. The cherry tomatoes, Gardener’s Delight, and small slicer yellow tomato Wapsipinicon Peach are going strong. My Peacevine (the OP equivalent of Sweet 100 still has a few also). And that’s just the heirloom types. My Sugar Rush and Super Sweet 100 tomatoes are doing really well–still flowering and reddening fruits.

    Super Sioux and Artisan Bumble Bee also have green tomatoes reddening up.

    Lettuce, Bok Choi, Spinach and Chard are thriving. Snow peas are flowering and setting pods.

    Inside I’m starting tomato seeds, squash and cantaloupe near the end of this month. Broccoli and celery next week. The warm weather stuff usually goes out in late March or early April. The broccoli and celery will go out in late February or early March.

    My asparagus stalks finally died back so I have to cut them down very soon as I could get new stalks appearing at any time.

    My hens still aren’t laying but I expect that will change within the next two weeks, and with the exorbitant price of eggs I can’t wait.

    Here’s wishing you and yours a Happy, Healthy and Prosperous New Year.

    1. Hi Ray, you know I love hearing how your garden is doing! There’s nothing better than fresh grown veggies and fruit. I’m going to try and grow some vegetables when the ground is leveled out. The builder left it a mess so, we need to hire someone to come clear the debris. Fibgers crossed we can get a vegetable garden growing in May. Happy New Year to you annd Jane and everyone else in our forum! Linda

  4. I’m not willing to dig thru 2 feet of snow to plant anything…lol…. I do wish we lived down south, but this has been the coldest December in decades. I’m just glad my husband added more daffodils to our spring garden.
