If you’re starting seeds in March, timing matters.
Some crops should absolutely go in this month. Others will set you back if you start them too early.
In this video, I break down exactly which crops to start in March — and which ones to wait on — based on your climate.
But here’s the key: your frost date controls everything.
That’s why I built GardenGuide.

Timing matters in March. Don’t guess.
I'm so ready to get started but I have a long way to go for Ohio
May 6th last spring frost
Our normal frost date is mothers Day. This year we're already hitting the 70's but 20's at night . By mother's Day its going to be to hot for our cold weather crops. Very weird year so timeing is a crap shoot. Our normt temperature right now should be highs in the 40's.
❤Excellent
I direct sow my pumpkins
I started Cukes inside, put them out a few days ago and of the 6 only 2 remain. 🤦🏼♀️ I forgot about them not liking transplanting. I plan on popping a few seeds in the ground. 😁
I've started building my garden in January this year. Pruned fruit trees and built 6 raised beds, planted seeds in febuary in my greenhouse. Built my beehive in febuary. Seeds already have their first set. Planting peppers now and
I’m in zone 6. We’ve had an unusually warm almost snowless winter. In NW Montana mountains. Soil never really froze hard. All my garden is in above ground large galvanized planters. I’ve got my cool weather seeds started. I will start tomatoes and peppers in a couple weeks. I have grow lights and heat mats. Many things will be moved to my little greenhouse which is against a large south facing wall of shop. Because the weather here can throw a freeze in June or even July I have good frost covers and keep a close watch on weather conditions.
Any tips on growing in 7.8 ph soil thats iron rich and in a wash but doesn't flood somehow and is about 70% sand and 30% clay but im on the side of it were its 60% clay and 40% sand what do i do? I water every 4th day do to soil staying wet 😂.
Oh im zone 8b or 9a i planted seeds in soil 4 days ago lol
Its definitely summer the coldest it got this winter was 23f at night in December 😂
Thank you Brian, have a blessed day ❤
my last frost date was May 28 last year, not sure when it will be this year, most likely around the same time this year, it's usually 10 to 14 days after before I can transplant warm weather plants or plant seeds
Would you do a video like this but for flower gardens? Love your videos, Brian!
Thank you Brian. 💚🙃
I'm excited to get started but I need to snow blow about 24" of snow in zone 6a to get to my garden 😢
Hi Brian Brilliant ❤ your videos jam packed with useful information for everyone 👍
Any gardenerthat has not been caught by frost is not a avid real gardener
Thank you for all the great information. I'm in zone 4-5 depending on winter lol. As I say welcome to Winnemucca lol
Thank you for how you organized this video. Something for us in every climate! Much appreciated
Any chance of a kick in the backside for those of us that are procrastinating this season? It's gonna be 77° tomorrow and Saturday. 😂🤣😂 Haven't even started my seedlings yet. 😬😬😬
In the south Bronx mid-March-April when we see forsythia bloom, maples budding, soil workable & warming to 60’s, the peas and radish row-markers go in. This year will start parsley and lettuce indoors. Need 12-inch-pot herbs basil, maybe German thyme. Crazy season last year, let the radishes flower and go to seed which self-seeded tiny radishes we had the fun of pulling after first snow. Growing things and caring for windowsill plants through the winter keeps us young!
Great advice. When I look at the charts for growing zones, I see I'm in 8a. But….I've lived in this location for 16+ years, and I know my last frost date is about 2-3 weeks after the growing zone shows to be. So, I wait for about 3 weeks before setting out my warm season crops. Also, I have found that if I wait until late July-early August to plant zucchini and yellow squash, I hardly have to deal with squash bugs—a terrible problem if I plant them in May.
Thank you for another informative video.
This is generally good advice, but there is one issue I have with planting early cold season crops, since I have taller (30”) raised beds. I decided to do the hugelkultur route, filling the bottom half of my beds with wood chips, brush, etc. to save on the initial fill cost for the beds. As a result, every year I get substantial settlement so I have to top up my beds 6 to 12 inches with fresh compost.
Doing that with bags of compost is very costly and I’m getting inferior quality product compared to a bulk delivery from a local source. But if I get the bulk delivery, I either have to have several cubic yards of compost sit on my driveway for six weeks until it’s time to plant regular season crops in most of my beds or fill all my beds and then have several months of precipitation washing half the new nutrients out of and compacting the soil.
Yes. Late frost😢 thanks 7a
Moving from zone 10 to zone 7 has been an adjustment for me. One thing I've learned living in a mild climate is to always have frost protection ready in case temps take an unexpected drop after plants go into the garden. My biggest mistake this year was forgetting to go through all my seeds and order some replacements. Waiting (impatiently) for the mail to arrive so I can get going!
My last frost is supposed to be April 28th but I was told by a local master gardener to wait for a couple weeks after to be sure.
Oh Brian! We’re gardeners! Of course we start more than we have room for!😂
The heat is already here in tx. 87 today 😢
Love, LOVE your Garden Guide…thank you!!!❤❤❤
Garden Guide looks really cool, can't wait to check it out! As a software developer I've been dreaming of making something to help me w gardening, especially something w a calendar and alert system.
In Texas, heat ain't coming. It's here. Still getting nighttime temperatures in 40s and 50s but daytime temperatures in the 80s and forecast into the 90s. It's crazy!!!
I’m in zone 6a. I’ve started my cabbage, broccoli, and cauliflower indoors. I also planted indoors my flowers that have a long germination time. I never put my vegetables like tomatoes and peppers outdoors until June 1st due to the soil being so cold. Anytime before June 1st and the soil will only be in the 50s
Great video Brian. Thanks for sharing.
I'm in Florida, last frost January 23rd, yet we had feels like of 25 last week. I want to start my tomatoes and cucumbers.
