Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, and sprouts poking out of the ground, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant spring flowers and young veggie plants when the ground thaws and the frosts are through. You might even want to directly plant seeds into the earth.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, veggies, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted by climate. Find your zone on the USDA growing zone map and learn when to plant seeds.

For example, you could transplant bell peppers outdoors in mid-March in Zone 10, but not until the end of May in Zone 4. You'll have good results with plants that have your zone number or less. In other words, a Zone 6 garden can support plants listed as Zones 1–6. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Be sure to read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
This region ranges from 7–9, with higher elevations in Zones 5 and 6. You’ll find fertile land in some places, desert and mountains with harsher conditions elsewhere. What you can grow and when will vary considerably depending on where you live. In Zones 5 and 6, the outdoor growing season doesn’t begin here until mid-March or even April, although you can start some veggies by seed halfway through February. Warmer Zones 7–9 can plant earlier, but if you’re in the desert, you’ll likely want to investigate indoor gardening in an enclosed porch or sunroom.

Utilize greenhouses to grow herbs and vegetables. Native plants like cacti, succulents, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat, like peppers, tomatoes, cucumbers, and squash. If you start them indoors and carefully introduce them outdoors in the shade, you can enjoy raising vegetables even in a dry climate. Heat-resistant spring flower seeds, whether they're annuals or perennials, can also often get an indoor start.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. Veteran planters and new gardeners alike should disinfect seed trays with a watered-down bleach solution before reusing them each year. When your trays or pots are prepared, plant your seeds. As for the soil, check to see if yours needs nutrient balancing. Choose fertilizers that match what you're growing. It'll help give your plants everything they need to grow big and strong.

Measure your finger to use it as a ruler. In general, you'll plant 3–5 seeds, then press them into the soil to the depth you need with your finger. Mark where you planted the seeds with a plant tag or toothpick. That way, you'll know where your seeds should pop up, and you'll know they're not weeds. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. These micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings don't get all this pampering in nature when they volunteer and grow wherever they please, so they can handle more than you think. However, don't go overboard, as your sprouts are still babies. You can even use an oscillating floor fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered enough but not drowning. Take wilted plants inside and give them a good drink, making sure they're strong before returning them outdoors.

Transplant Young Plants Into Their New Homes
You've raised your baby plants from seeds, watched them sprout, and carefully hardened them off to brave Mother Nature. By now, your plants have 3 or 4 true leaves — they'll look different from the miniature seedling leaves. When you're not expecting soaking rain, and the ground is warm, look into transplanting your big sprouts into their new outdoor home. "Transplant" means that you put these small plants straight into pots or garden soil. In cases where you direct sowed, you may still want to shuffle plants around for the best spacing and sun. That's also a transplant situation, as is repotting plants into larger pots.

Protect Your Garden With Mulch
Finish it off with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more fruit and flowers. Mulch keeps your soil moist and controls weeds. Compost and mulch can be purchased in-store or created at home. The next time you're looking for "mulch near me," stop by the Garden Center to get the perfect amount.

Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your San Rafael Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What's my planting zone?

Check the USDA zone map, as planting zones have shifted over the years. Planting zones with higher numbers can plant earlier in the year. Increase your odds of successful gardening by choosing plants that are meant for your zone.

What does direct sow mean?

If the ground isn't frozen solid and the soil isn't cold, consider planting your flower, veggie, or fruit seeds directly into your garden. This is called the "direct sow" method. Plant after the threat of frost is gone for the season, as sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed package for how and when to sow seeds.

How do I plant fruit seeds?

Read your seed packet for the best info on how to grow fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary from one type of plant to the next. Certain seeds should only be sown indoors, and your seed packet will tell you that, too. For more details, check out how to plant flower seeds.

Should I harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them before you transplant them. Hardening allows your seedlings to adjust to the great outdoors and rain, sun, and temperature swings, making them more resilient against cold snaps. It slows their growth until they're strong and ready to take off during a spring warm front.

How do I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick. They'll gain strength even though you shouldn't see them moving. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pots or pellets, work for new and experienced gardeners. You don't have to use these starters if you're planting in soil, but you may want to. Starting seeds in peat pots works best for delicately rooted plants like carrots and beets, as well as flowers that require an acidic pH. Some people prefer coir starters instead, as they have a neutral pH. Check what type of soil your plants need to help narrow it down, and chat with a garden center associate if you need more info.
