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 planting zone am I in?
Check the USDA 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 isn't frozen or cold, consider planting your flower, veggie, or fruit 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 packet for how and when to sow seeds.
Do you carry organic plants and seeds?
We offer many organic gardening options, including organic veggie seeds and fruit seeds, as well as organic flower and herb seeds that are subject to availability. We carry the organic soil to plant them in as well as the organic fertilizer to feed your plants.
Do I have to harden off my seedlings before planting them outside?
Yes, for best results, if you raised plants indoors from seeds in your own plant nursery, harden them before you transplant them. Hardening is the process of getting them used to the great outdoors and sun, rain, 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 seedlings.
How do I plant a transplant or baby plant?
Squeeze the plastic around the plant to loosen the soil. Gently coax your transplant and the surrounding clod of dirt out into the palm of your hand, 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 tamp down the ground too tightly. Your plant baby needs to breathe.
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.
Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for warmer temperatures, sprouts poking up, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring flowers when the frosts are through and the ground thaws. You might even want to plant organic seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery?
Plant Hardiness Zones Explained
The first thing to know when planting veggies, 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 plant hardiness zone map and learn when to plant seeds.
For example, you could plant bell pepper seedlings 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 7 garden can support plants listed as Zones 1–7. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. Always read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it should 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 Palm Springs and San Bernadino. 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. Growing season begins early and ends late in this part of the country. A wide variety of flowers, plants, and vegetables thrive in southern California. You can even grow citrus trees for fresh fruit when you plant somewhere with good soil drainage. You’ll have excellent results with peppers of all heat levels and colors, including jalapeños, bell peppers, and more. Zucchini, cucumbers, squash, and pumpkins, which are direct sow only, will flourish. Planting tomatoes will yield thriving fruit and leaves, 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 grow outside with ease. 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 flowers, both annuals and perennials, are sensitive to that much heat and sun, so research to find varieties that can handle the weather before planting outdoors.
Start Seeds Indoors
Grow your garden from seeds by starting them indoors in your own plant nursery. We've got all the seed starter supplies you'll need. Make sure you have a warm and sunny spot that gets at least 12 hours of light and good soil, a spray bottle of water, and patience. Then you have everything you need to try your hand at growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.
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. 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 certainly don't get all this pampering in nature when they volunteer and grow wherever, 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
Make sure to harden your seedlings for best results when they're grown. On days that are warmer than 45–50 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. Cloudy days are fine, but no direct sunlight or harsh nighttime chills yet. After a week or more of this, you can leave them out overnight if the temps stay warmer than 50 degrees. Cover your plants if they're in the ground when a late-season frost sneaks back in.
Transplant Young Plants Into Their New Homes
When your plants have three or four true leaves — different from miniature seedling leaves — it's time to transplant them. In quality soil, dig a hole the same size as the dirt plug where your transplant has been growing. If your ground soil isn't fantastic, dig a slightly bigger hole and fill the extra room with nutrient-rich topsoil. Apply fertilizer as directed, either on top of the soil after it's planted or in the hole. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.
Protect Your Garden With Mulch
Finish it off with mulch and compost. Mulch controls weeds and keeps your soil from drying out. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more flowers and fruit. Mulch and compost 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
Late winter into early spring is an exciting time in the world of gardening. Plan your garden and landscaping, prepare to fertilize your lawn, 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 an outdoor rug or artificial grass to your outdoor space. Shop for the soil, fertilizer, and seeds you need in the aisles of your Lemon Grove Garden Center, online, or on our mobile app. Let's get growing together.
