Are you wondering what to plant in March? I can hardly wait to get my hands in the soil, what about you? I can see that my puppy has been digging in one of my raised garden beds. I’m going to have to put a stop to that little trick.

I’ve been outside turning the soil every month to make sure all is well. I will add some new earthworm casings this year, but that’s all I need. This year

I’m going to add some shade screens on my tomato cages to see if I can grow a few months longer in this heat here in Southern Utah.

One thing you may want is a cold frame to protect your plants from frost or high winds.

My friend, Rick Stone from Our Stoney Acres is an expert at gardening year-round. He even shows how to make a COLD FRAME!! He lives where it snows in the winter, just so you know.

I’ve hired someone to build some “greenhouses” around several of my raised boxes, I can hardly wait to try them out.

When they are finished I will post pictures and keep you updated regarding how they work out for winter gardening and controlling the summer heat with shade materials.

What Does The Term pH Level Mean

Are you wondering what the term pH level is when gardening? Each plant prefers a different level of acidity to grow the very best harvest. The level of acidity varies between each plant.

Therefore, you can adjust the pH of your soil by adding lime or sulfur to bring it up or down depending on what your soil needs.

You can have your soil tested, possibly by your state extension service, or try and do it your self with a soil tester. pH Tester

Soil Amendments

The first thing we need to do is pull any weeds that have come up since the last time you turned over the soil. Dig out any leftover crops that you may have missed the last time you harvested.

Turn the soil several times and add the following amendments, if you need them. You may remember I have raised garden beds because I don’t want to bend down as far to work my garden anymore.

I’m adding two more raised beds this year, I feel an urgency to raise more food for my family.

What to Plant in March By Zone

I realized recently that I mostly posted on what to plant each month based on where I lived, but not everyone lives here! So, I wanted to share with you what to plant by zone as well.

Zone 1-2

There isn’t a lot that you can plant in zone 1 and 2 during March, but you can start a few things. Here is some you can try:

  • Asparagus
  • Celery
  • Chives
  • Endive
  • Leeks
  • Radishes

Zone 3

Its probably still pretty chilly in zone 3 during March, but there is still quite a bit you can start planting. You can start with the following:

  • Onions
  • Tomato
  • Cauliflower
  • Cabbage
  • Brussel Sprout Seeds

Zone 4

Zone 4 is a lot like zone 3, so you can plant the same things and a few more. Here is a list:

  • Peppers
  • Egg Plants
  • Onions
  • Tomato
  • Cauliflower
  • Cabbage
  • Brussel Sprout Seeds

Zone 5

In zone 5, some things need to start off indoors whereas others can go straight into the garden. You will, however, want to make sure you use cold frames to protect against any unexpected frost that can happen in zone 5.

Tomatoes, peppers, and eggplants will need to be started indoors and transplanted to your garden at the end of March or early in April. Here is a list of things you can plant outdoors:

  • Potatoes
  • Peas
  • Lettuce
  • Radishes
  • Carrots

Zone 6

It may not be the ideal time to start planting in zone 6. However, if the weather is mild, you can start planting roses, trees, and shrubs. Additionally, the following can be moved outdoors:

  • Broccoli
  • Cabbage
  • Cauliflower

Zone 7

In zone 7 the weather is milder, so you have a few more options in what you plant in your garden. Be sure to plant the following around mid-month:

  • Carrots
  • Beets
  • Kohlrabi
  • Radishes
  • Lettuce
  • Turnips
  • Swiss Chard

Additionally, you can transplant the following from indoors to outdoors:

  • Onions
  • Shallots
  • Broccoli
  • Cabbage
  • Cauliflower
  • Collards
  • White potatoes
  • Asparagus
  • Chives
  • Rosemary
  • Thyme

Zone 8

Nights can still be pretty chilly in zone 8, so make sure you row covers and windbreaks on hand. Plant the following in March:

  • Spinach
  • Turnips
  • Mustard
  • Beets
  • Carrots
  • Broccoli

In mid-month, you can begin planting the following:

  • Corn
  • Tomatoes
  • Squash
  • Peppers
  • Cucumbers

Zone 9

Like zone 8, you can plant quite a bit in zone 9 due to it being quite warm in March. It may be cool in the evenings. But, for the most part, you don’t have to worry much in zone 9. Here’s what you can plant:

  • Cabbage
  • Broccoli
  • Spinach
  • Radishes
  • Asian Greens
  • Lettuce
  • Parsley

Additionally, you can move the following from indoors to outdoors in mid-March:

  • Tomatoes
  • Peppers
  • Eggplants

Zone 10

It is pretty warm in zone 10 during March. So, you can plant warm weather plants at this time. Here is a list of what you can plant:

  • Okra
  • Sweet potatoes
  • Mustard
  • Collard greens
  • Cucumbers
  • Melons

What To Plant In March

I’m starting my seedlings right now inside my home. I have never bought the lights that people use and it always seems to work out.

I do have a lot of good sunshine coming through our windows and that is a HUGE help to germinate these seeds. I only buy USDA Certified Organic Non-GMO seeds.

I also purchase plants that are USDA Certified Organic Non-GMO seeds that are produced by professional growers.

1. Beets

When prepping the soil for planting beet seeds, please do not neglect the needs of these red beauties. They prefer well-drained soil, never clay as I have here in Southern Utah, which is too heavy for the large roots to grow.

If your soils are hard it may cause the beet to be tough and not be the best vegetable to cook.

The temperature must be at least 40 degrees F. (4 C) to plant the seeds in order for them to germinate. Beets do not like the hot weather and actually do poorly in the high temps.

When the soil is ready, plant the seeds 1 to 2 inches apart and cover the seeds with soil and sprinkle with water. In about 7 to 14 days you will start to see a few sprouts.

Thin as needed to keep the roots a good size for harvesting. You may want to plant some beet seeds every 2-3 weeks to have a good harvest longer.

You can plant them in partial shade, but make sure the soil depth is at least 6-8 inches to produce really good roots. The beets are ready to harvest in about 8 weeks.

When ready to dig them, gently remove the soil around each root. The greens can be harvested when the beets are young and the root is small.

pH level for Beets: 6.0-7.5

Plant In March

2. Broccoli

Broccoli is a very hardy vegetable and you can typically have two crops per season (spring and fall). Broccoli needs at least 6 hours of sunshine each day, so plant the seeds where they will get the proper sun.

Broccoli seeds need to be planted at least 18 inches apart and in rows that are 24 inches wide. They need almost 1.5 inches of water per week if the rainfall doesn’t cover it.

The ideal temperature for broccoli is between 65 and 80 degrees. The soil must be well-drained for the best growth. To be sure about the soil, have it tested or purchase a soil kit.

Watch for the flower head beginning to form in the middle of the plant every day. If the buds start to turn yellow, cut the head from the stem. You will still see small shoots grow that are great to harvest.

pH level for Broccoli: 6.0-7.0

3. Carrots

Carrots like really smooth, loamy soil with nutrients added as shown above. I like to moisten the soil slightly and sprinkle the seeds over the soil and cover them with compost.

Keep the rows about 3 inches apart and stagger planting the seeds over two to three weeks to have an abundant harvest for the season.

If you live where the heat is intense, be careful as carrots do not like to dry out. If you water them by hand for two to three weeks after planting the seeds you will soon see the little sprouts.

This is when you will fertilize with some Miracle-Gro Fertilizer and thin the carrots as needed. Use mulch to cover them if you live where the summers are extremely hot.

pH level for Carrots: 5.5-7.0

Plant In March

4. Cauliflower

Cauliflower is a cool-season crop, however, it’s a bit more temperamental than broccoli. The trick is having cool temps consistently in order to produce crops with larger heads like grown in coastal neighborhoods.

Cauliflower likes temps around 60 degrees, if the temperatures get too hot or too cold, it stresses the plants and produces tiny buds.

Plant the seeds about 18 inches apart with rows 30 inches wide. Cover the seeds with soil and compost. Water in the seeds gently.

When the cauliflower heads are about two inches in diameter, cover them with their own leaves, if possible, to shade and protect them. Ideally, the head will grow to 6-7 inches in diameter.

pH level for Cauliflower: 5.5-7.5

5. Celery

Celery seeds are so tiny you may want to mix them with sand before sprinkling them over the loamy, well-drained soil described above with nutrients added.

The temperatures need to be at least 50 degrees F. (10 C) before you plant the seeds. Cover the seeds with a little bit of soil and sprinkle the seeds with water.

They like to be planted shallowly. Once you see some sprouts you will want to thin them. They will not tolerate a drought at all.

They need a lot of water, so keep that in mind where you plant them. Please fertilize regularly to have the best harvest.

pH level for Celery: 5.8-7.0

6. Lettuce

Add the amendments above to the soil where you will plant your lettuce seeds. The nice thing about lettuce is it’s so easy to grow and sprouts up pretty fast.

Just make sure the soil is loosened, loamy, and well-drained. Lettuce loves nitrogen and potassium, so keep your eye on the leaves as they start to grow.

Work in a lot of organic matter or compost. Lettuce matures in 55 to 60 days. Romaine takes longer to mature, and so does head lettuce types.

Plant the seeds about 1/4 inch deep, tamp them in the soil, and water them in. Easy and simple. Read the package to space according to the lettuce you choose.

Seeds will not germinate in soils above 80 degrees F. or warmer. You can start some seeds indoors and transplant the seedlings into a shady spot when the weather is too hot outside.

You may want to choose heat resistant varieties if you live where the temperatures get too hot in the summer. It’s better to pick early than late because the leaves become bitter.

pH level for Lettuce: 6.0-7.0

7. Onions

Plant the onions sets about one inch deep with the bulb end facing down about 5-6 inches apart. Onions growth will depend on how much sunshine they will have.

“Long Day” onions need 10-14 hours of sun each day. “Short Day” onions need 10 hours of sunshine to grow correctly. “Day Neutral” onions will grow very well regardless of how many hours of sunshine they have.

ONIONS: “Long Day”=Zone 6 and colder areas. “Short Day”=Zone 7 and warmer. “Day Neutral”=they can grow anywhere but perform better in zones 5 and 6. Consistent soil moisture and good fertilizer is key to growing the best onions.

pH level for Onions: 5.5-6.5

8. Peas

Peas prefer cool weather, so March is a good month to plant your peas. You can plant them as soon as you can work your soil. If the soil temperatures are 10-20 degrees C or 50-70 degrees F that is best.

The best time to sow peas is mid-February clear until the end of May. Of course, you can plant them again in July through mid-August, depending on how hot it is.

If your soil is moist or damp do not soak your peas, you don’t need to. I have never soaked my peas.

Make sure your soil has the amendments it needs. I prefer bush peas, but that’s because those are the ones that seem the sweetest.

My favorite ones are called Little Marvel. They only grow about two feet tall, and that works for me. They are sweet to the taste and can be harvested in about 60 days.

You may want to trellis them. Plant the seeds about 4-6 inches apart and 1/2 to 1-inch deep.

pH level for Peas: 6.0-7.5

9. Radishes

I like the radish called, Red Champion because they are larger and have bright red skin. They grow in small areas and the days to maturity are 25-30 days.

Another one I like is called Pink Beauty because the white flesh is crisp and mild. They grow really well in pots or containers. Their days to maturity are 25-30 as well.

I just sprinkle the seeds over the soil, do a slight soil coverup and sprinkle with water. If you stagger the planting days you will have several days of freshly picked radishes.

pH level for Radishes: 6.0-7.0

Plant In March

10. Spinach

I plant the New Zealand spinach seeds because they can withstand the heat of Southern Utah. It’s a large growing plant, but I make salads, smoothies, and freeze a lot of spinach for the year.

This is one spinach variety that grows from spring to fall without any issues. The more I cut it back the more it grows, literally. Days to maturity are 75 days.

Here again, make sure your soil has the amendments above and you turn over the soil again and again. Plant the seeds at least one-foot apart and the rows two feet apart.

pH level for Spinach: 6.0-7.5

How To Hand Pollinate

Hand Pollinating

All you need is a paintbrush or cotton swab (see above). If you need to hand pollinate because you are not seeing any fruit develop, here is something you may want to try. You do this by removing the male blossom (male blossoms do not have fruit behind them). They produce pollen leaving the center covered in the 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.

Final Word

I hope today’s post on what to plant in March inspires you to start a garden if you haven’t already. You can try planting in the ground, in pots, planter bags, and in raised gardens.

Don’t forget to look for community gardens in your area. They are great for getting to know your neighbors. I love, love, love Farmers Markets, but my gut tells me I need to grow food in my own yard.

What are you thinking right now about raising your own food? I wish I had more land, but that’s not going to happen. May God bless this world. Linda

    Thanks, Linda ~
    I always wonder what and when to plant. Of course, I have other issues with growing a garden as I live in an apartment with a tiny balcony that only gets afternoon sun.

    We are still getting some pretty heavy frost here in Washington state so I don’t think all of the planting you mention for March will be appropriate for my area. I do have one aspect that someone with an actual garden has in that my balcony is on a second story and is protected by a wall. I probably would be able to plant earlier than someone planting in the ground.

    • March 2, 2019 at 9:54 am

      Hi Leanne, living in an apartment is a little tricky for sure. I keep seeing posts about growing veggies indoors. I need to see if it really works. If it works I will write about it. Fingers crossed. Linda

      Try to build or have built for you a DIY miniature/micro solar greenhouse. Just make sure that you have at least 2-3 holes near the bottom ( 2 in back/side , and 1 in front). You want to make sure that your plant(s) can breathe. After all, what they breathe out is what we breathe in and visa/versa. And, it is not just for the plants alone , but also the soil as well needs a sufficient amount of air.

    Linda I too have been itching to go play in the dirt! Here in NW Florida, I just got the last of my onion sets in the ground. Planted 2 yr old asparagus in my best raised bed a couple of weeks ago and have sprouts showing through the mulch. Am trying garlic. Will be planting beets, potatoes and sweet potatoes this week. Will be starting seeds for cucumber, eggplant and Malabar Spinach indoors to be ready after our last frost.

    Will be interested in the ‘greenhouse’ for the raised beds you mentioned. And I have shadecloth I add to my tomato cages to cut down on the heat damage done in midsummer. I add the shadecloth to the South and West sides. It has helped the tomatoes tremendously and kept the plants from just burning up. Hope it works as well for you!

    • March 2, 2019 at 10:03 am

      Hi BDN, it sounds like we are both excited about gardening!! I’m glad you tried the shade cloth, I’m really hoping it works here. I have never planted asparagus!! How exciting!! Yay for having our own gardens! Linda

    10 vegetable seeds to plant in march
    While these may be great for Utah, here in Ohio with our wet springs and last frost date around May 15, we have to adjust a bit. By looking at the germination numbers on the seed package, and working back from May 15, you can get a rough idea of when to plant, also taking into account the time to harvest.
    We’ll be starting some seeds in the next week, either indoors or in the greenhouse; but, that greenhouse has so far been an experiment, since it can be at ambient on cold nights and very warm in the day time. I have seen temperatures in the 20’s @ night both ambient and in the greenhouse; but, during the day, with the outside temperatures still in the 20’s & 30’s, the greenhouse will get up to the 40’s & 50’s. It’s been something we’ve wanted for years and now that we have it, we’re still learning to use it.

    what does the term ph level Mean
    As an engineer I have to do the details, LOL.
    In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions.
    The point is that you need to know the pH range your plants require and measure it. I have a pH metet with two prongs / probes that ate simply pushed into the ground. They are very inexpensive and a tool that like a shove or hoe, is very useful.

    soil amendments
    We use lime or wood ash to raise the pH (lower the acidity) and pine needles to lower the pH (raise the acidity).
    We also use compost with various things including a lot of chicken manure.

    Raised beds
    We tried them and are abandoning them this year, going back to row gardening.

    1. beets
    We always have some of these since they are easy to grow.
    2. broccoli
    We’ve tried from seed; but, generally purchase plants. This year we’ll try both.
    3. carrots
    Another easy and nearly bulletproof one; but, best in clean sandy soil with no large rocks.
    4. cauliflower
    Anoter we usually purchase potted plants; but, will try seed once again.
    5. celery
    We’ve never had this work out, ever; but, the seed is cheap, so who knows.
    6. lettuce
    We usually grow loose leaf instead of Iceberg (head) since we find it is easier to grow.
    7. Onions
    We always plant lots of sets; but, the outcome often depends on our rain
    8. peas
    Another easy to grow in several carieties.
    9. radishes
    Not our favorite; but, easy to sow & harvest with little work.
    10. spinach
    Another easy one to sow & grow.
    Some things we like but you didn’t mention are Eggplant and Spaghetti squash usually planted in mid April.
    I’m just hoping for a dry spring, since these have been some of the wettest years in a long time.

    • March 4, 2019 at 3:54 am

      Hi Ohio Prepper, oh my gosh, I have wanted a greenhouse for years. I love your comment. Please keep me posted on how it’s working out for you. I hope we get a dry spring as well. I’m praying we don’t have mudslides. Stay safe and well. Great comment! Linda

    I have wanted a greenhouse for years

    So did we and we finally got a small one. If you have Harbor Freight in your area, sign up for their email coupons and look for discounts. While they have larger ones, the one we opted for is 6x8x6 Width/Length & height in feet. The 6’ height is at the peak, so the normal base they recommend made from 4×4’s has been extended with a combination of 2×2’s and 2×12’s to add height. I don’t recall the regular price; but, they often have a coupon to get this one for $199.00 which is what we did. A larger one would be better; but, for now this one let’s us get our feet wet on the cheap. You can see the details byt looling at the pdf manual here: https://manuals.harborfreight.com/manuals/47000-47999/47712.PDF

    Please keep me posted on how it’s working out for you.

    Will do.

    I hope we get a dry spring as well. I’m praying we don’t have mudslides.

    Our terrain doesn’t get mudslides; but, tilling and working a spring garden working in thick mud is hard if not impossible to do.
    I can send you photos of our installation if you’re interested.

    • March 4, 2019 at 5:42 pm

      Hi Ohio Prepper, thanks for the information! Let me see if I can get one and I’ll have you send me the pictures if I can get that one. Thank you so much!! Linda

        I just spent last night planning my garden. I’ve done a mix of seeds and seedlings, but this year I’m just going to direct sow. Every year is an experiment.

        This winter, my husband covered my garden with leaves. I’m not sure what to do with them now. I guess I’ll rake off the excess and wheel it over to my compost pile and dump them there. Use what’s left as mulch in the garden. What do you think?

        Also, any ideas for keeping your seeds straight as they come up as seedlings?

        • March 16, 2019 at 11:21 am

          Hi Shyla, keeping the seeds/seedlings straight is a problem sometimes. I mound dirt around the seedlings if they are not growing up straight. Leaves are actually really good mulch if they have broken down over the winter. If not, put them in your compost pile. I have been gardening 50 years and it’s still an experiment, each year I learn something new. Life is so awesome when working in the garden. Keep gardening, it’s so fulfilling!! Linda
