Let’s plant in March! Spring is just around the corner but it isn’t too early to think about the seeds you should plant in March! It is not too early to think about what you’ll be planting and getting your seeds ordered.
These vegetables, herbs and fruits will work for most people but if you’re in an area, like me, with extreme heat you’ll want to check out planting calendars for your zone.
If you’re in Phoenix I recommend using the calendar from the Maricopa Extension Office.
If you aren’t sure what planting zone you are in the USDA has a great interactive map for you. And you can just put in your zip code and it will tell you exactly what planting zone you are in.
Seeds You Should Plant in March
This list is going to work for most people but definitely check for your specific zone.
Root Vegetable Seeds to Plant
- Beets – If your soil hasn’t consistently reached 50 degrees in March you’ll want to wait. Consider starting your seeds indoors and then transplant later. To help with germination Rodale’s suggests that you soak your seeds for a few hours before planting.
Beet Seeds to Consider: Early Wonder, Boltardy, Detroit Golden
- Carrots – Carrots should be planted directly into the garden (don’t try to start them indoors). It is best to plant them about 4 weeks before the last frost. Here in Phoenix, carrots are a fall and winter crop.
Carrot Seeds to Consider: Tendersweet, Danvers, Amarillo Yellow

- Onions – You can plant onion seeds, sets or beginning plants.
Even though onions are a “root” crop Farmer’s Almanac recommends treating them like a leaf crop.
Onion Seeds to Consider: Spanish Sweet, Evergreen Bunching, Red Burgundy

Leafy Green Vegetable Seeds You Can Plant in March
- Spinach – More of a cool weather veggie. Planting spinach in early March should give you plenty of time to harvest this tasty treat before the summer heat causes it to bolt. Plant 4 – 6 weeks before last frost.
Spinach Seeds ton Consider: Bloomsdale, Noble Giant, Matador Viking
- Lettuce – Make sure your spring lettuce gets plenty of light but not all day; it won’t bolt as quickly if it has some shade too.
Lettuce Seeds to Consider: Classic Romaine, Buttercrunch, All Year Round
Other Vegetable Seeds You Can Plant in March
- Broccoli – since this is often a fall veggie and likes cooler weather, plant a quick growing variety to ensure you have time to get a good head before summer. The hybrid (non gmo) Flash variety is said to be good for late crops.
Broccoli Seeds to Consider: Di Cicco, Early Purple, Waltham
- Cabbage – Start your cabbage indoor about 7 weeks before your last frost.
Cabbage Seeds to Consider: All Season, Red Acre, Savoy Perfection
- Corn – Start directly in garden, not indoors; in soil at least 60 degrees. Corn grown commercially is 90% GMO so it is important to plant and consume non-gmo corn.
Corn Seeds to Consider: Bantam Sweet, Rainbow Corn, Fishers Earliest

- Cucumbers – Make sure you choose a variety that fits your space (bush or vining). Best to plant in the garden after the last frost has definitely happened.
Cucumber Seeds to Consider: Marketer, Straight 8, Space Master
- Peas – Sow after your last frost. Peas won’t do well once it gets really hot so if you have a hotter climate you may want to wait on peas and grow them in the fall.
Pea Seeds to Consider: Sugar Snap, Little Marvel, Sugar Ann
- Peppers – Peppers love the heat but you can start them in March, indoors, and transplant them later.
Sweet Pepper Seeds to Consider: Banana, Chocolate Bell, Red Cherry
Hot Pepper Seeds to Consider: Anaheim, Habanero Chocolate, Jalapeno
- Summer Squash – Another vegetable you can start indoors in March for transplanting later. Squash loves the sun and good drainage.
Squash Seeds to Consider: Black Beauty, Scallop, Round de Nice
- Tomatoes – Here in Phoenix, my tomatoes are already 6 – 8 inches tall in March. But if you live in a colder climate you’ll want to start your tomatoes indoors and plant them outside when the frost has passed.
Tomato Seeds to Consider: Homestead, Ponderosa Red, Rainbow Heritage

Fruit Seeds You Can Plant in March
- Melons – I love growing melons because most like long hot summers (aka Phoenix). But you can start them inside in the March to get a head start on your summer garden.
Herb Seeds You Can Plant
Many herbs love the warmer months or try growing them indoors!
