If you like to buy starters, my favorite local spot to do so is at Love apple farm (which you can now preorder your crops online right now and then pick up in person in April)
Or at our local Scarborough Gardens.
Why I no longer buy vegetables from Home Depot:
Bonnie uses high nitrogen fertilizer on their plants to get that deep blue/green color. This stresses the seedlings and puts them out of sync with their natural growth cycle
What to plant starting in March:
March is a great time to start planting your seeds indoors or in a green house. If you have a great window with a ledge, I would stick some small pots in the window. You can get them for $10 on amazon or at our local Scarborough Gardens.
I like to plant mine with 420 Recipe soil that I get at Scarborough. This soil is dense with nutrients your plants need to thrive. I will also mix it with Plantonix (lnk.bio/Plantonix) this is a small business outside of Ashland Oregon. They use all natural and organic ingredients. Their neem oil is one of my favorites to deter insects from eating my plants without harming them.
I am in zone 9, so starting in March I will start planting indoors:
eggplant, tomato, squash, and pepper
Spinach, carrots, kohlrabi, radishes, lettuce, potatoes, asparagus, corn, cucumber, rosemary, chives, and thyme
seeding indoors: pole beans, corn, squash, watermelon, cantaloupe, cucumbers, sweet potatoes, peppers, and tomatoes. You can also plant ginger.
You may start to transplant peppers and tomatoes outside.
When purchasing starters Avoid picking out plants that already have blooms or small fruit. A plant that has switched to reproductive phase will not normally reach maximum productive potential. The objective is to grow a seedling and set it out so that it can go through the juvenile growth phase before setting any fruit. A healthy plant should be nearly 2 feet tall and spread over 1 foot across before it flowers and fruits. Getting a plant successfully through this juvenile growth phase is crucial to overall production.
