Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, as well. Planning your garden lets you make the most of your time and space. You can also add beauty and interest with hardscaping, stonework, and water features. No matter what outdoor projects you choose to tackle, The Home Depot Garden Center in San Luis Obispo can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, vegetables, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted into blocks by climate. Find your zone on the USDA 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. Always read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
This area is in growing Zones 8 or 9, but it’s desert, so utilize greenhouses to grow herbs and vegetables. Native plants like succulents, cacti, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like cucumbers, squash, tomatoes, and peppers. If you start them indoors and carefully introduce them outdoors in the shade, you can enjoy raising vegetables even in a dry climate. However, many spring flowers are sensitive to that much sun and heat, so research to find which varieties can handle the weather before planting outdoors.

An indoor garden of greenery is also lovely, so create an oasis inside your home. A sunroom or enclosed porch is a great place to encourage plant growth, especially with plant stands and pots of all sizes. Your spring flower seed choices, whether they're annuals or perennials, can also often get an indoor start.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less planning and tending than growing indoors. If you like to go with the flow, follow the instructions on your seed packet and try it.

Your seeds might struggle to grow or get washed away, or critters or insects might eat the sprouts. But if you're really lucky, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your sown seeds will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are primed to survive, although there are no guarantees.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors instead. In general, you can plant seeds indoors about a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed packet, but that's where the similarities end.

You're responsible for giving them quality substitutes for rain and sunlight. Keep your seeds warm with heating mats and grow lights, water them carefully with a spray bottle or watering can, then thin them as they germinate in groups of three. Give them a boost with a gently blowing fan as they lengthen into sprouts if you'd like. Harden them off to get them used to outdoor conditions, then transplant them into your garden when they're big enough.

Transplant Young Plants Into Their New Homes
By now, your plants have three or four real leaves — they'll look different from the miniature seedling leaves. When the ground is warm, and you're not expecting soaking rain, look into transplanting your small plants 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 sun and spacing. That's also a transplant situation, as is repotting plants into larger pots.

Protect Your Garden With Mulch
Finish your garden bed with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more flowers and fruit. Mulch controls weeds and keeps your soil from drying out. Mulch and compost can be DIY creations, but you can also purchase them in-store. The next time you're looking for "mulch near me," stop by the Garden Center to get the right 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 which spring flowers to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your San Luis Obispo 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 planting zone map, as planting zones have shifted over the years. 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 soil is warm and pliable, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed packet for when and how to sow seeds.

How do I plant flower seeds?

Check 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. Some seeds should only be planted indoors, and your seed envelope will tell you that, too. For more details, check out how to plant seeds for a garden.

Do I have to 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, 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.

What do I do before planting transplants or seeds outside?

Before you plant, make sure that your plant will have the right amount of sun, it's warm enough outside, and the soil is healthy. Check your seed packet to see if it likes full sun, shade, or partial sun, as well as what time of year it should be planted. Space your plants as described on the seed packet for best results so your plant babies have room to grow big and strong.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient 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 cucumbers and eggplant, as well as flowers that need acidic soil. 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.
