When you're ready to seed your lawn, our calculator helps you estimate the amount of grass seed you'll need to get the job done.
Enter your preferred material, the square footage and mulch depth of the coverage space for accurate results.
We'll calculate the amount of fencing you should purchase based on your property needs.
What number planting zone am I in?
Check the USDA growing zone map, as planting zones have changed slightly over the years. Zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of successful gardening.
Is it ok to plant seeds outside in the spring?
If the soil isn't frozen or cold, consider planting your veggie, fruit, or flower seeds directly into your garden. This is called the "direct sow" method. The time to plant will be 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 envelope for when and how to sow seeds.
How do I plant seeds?
The best source of information is the seed package your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary with each seed type. Certain seeds should only be planted indoors, and your seed packet will tell you that, too. You'll be a pro at planting seeds in no time.
Should I harden off my seedlings before planting them outside?
Yes, if you raised plants indoors from seeds in your own plant nursery, harden them first before you transplant them. Hardening is the process of getting them used to outdoor life, spring rains, and temperature swings. It slows their growth until they're strong and ready to take off during a spring warm front. Hardening also makes your plants more resilient to a sudden cold snap. Read your seed packets or speak to a garden center associate for more info on caring for your tender seedlings.
How do I plant a transplant or baby plant?
Squeeze the plastic around the plant to loosen the soil. Carefully coax the plug of dirt with the plant into your palm, then place it into the hole you dug for it. Make sure the top of your transplant's soil is even with the garden soil, and carefully press the earth into place. Avoid leaving the plant as an island with a moat around it, and don't pack the ground too tightly. Your plant baby needs to breathe.
What are seed tapes?
If you want more guidance in planting or are dealing with extremely tiny seeds, consider seed tapes. They're biodegradable pieces of paper with tiny seeds affixed at regular intervals. Just bury the tape and water as directed. If all goes well, you'll have perfectly spaced sprouts pop up soon.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Lawn care is often a priority as well. Don't forget to clean out the shed and sweep the gazebo in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, you'll find that The Home Depot Mira Mesa Garden Center is your local plant nursery to help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing to learn when planting vegetables, spring flowers, 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 planting 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. The plants that'll thrive in your area are in your zone — plus all the zones numbered less than that. In other words, a Zone 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Be sure to read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it will likely even out as time passes.
Gardening in Your Growing Zone
The southernmost part of California is primarily in Zones 9 and 10, with small areas of 6–8 sprinkled in near San Bernadino and Palm Springs. A temperate Mediterranean climate on the coast means there's usually gorgeous gardening weather. Areas in the mountains and desert are more challenging to grow vegetables in, but indoor gardening is an excellent workaround.
For more temperate areas, find your planting zone and prepare to get planting. The weather and climate make it easy to get and keep a beautiful garden. A wide variety of flowers, plants, and veggies thrive in southern California. If you've got good soil drainage, you can even grow citrus trees. You’ll have excellent results with peppers of all heat levels and colors, including bell peppers, jalapeños, and more. Zucchini, cucumbers, squash, and pumpkins, which are direct sow only, will flourish. Planting tomatoes will yield thriving leaves and fruit, as they’re tropical in origin and are happiest in the heat.
In the desert, native plants like succulents, cacti, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat. 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.
Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. It doesn't give you as much organized planning in terms of reliability and spacing compared to indoor starts. However, if you like to go with the flow, follow the instructions on your seed packet and try it.
Prepare to deal with whatever hand nature deals you: Be ready for all your seeds to sprout, none of them to come up, and anything in between. Your seedlings will need to survive wind, rain, and sudden cold snaps, as well as critters and insects that crave tender greens. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.
Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors in your own plant nursery. 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 sun and rain. Keep your seeds cozy with warming mats and grow lights, water them carefully with a mister 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 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. These large seedlings that are ready to be planted can also be called "transplants" or sometimes "starts." 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 flower bed with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more flowers and fruit. Mulch controls weeds and keeps the soil moist. 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 right amount.
Greet the Spring
Early spring is an exciting time in the world of gardening. Prepare to fertilize your lawn, plan your garden and landscaping, and browse The Home Depot nursery to find inspiration on which spring flowers to plant when the weather warms. For those without lawns, consider adding artificial grass or a pellet grill to your outdoor space. Shop for the seeds, soil, and fertilizer you need in the aisles of your Mira Mesa Garden Center, online, or on our mobile app. Let's get growing together.
