Location
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.
How do I know what planting zone I'm in?
Check the USDA zone map, as planting zones have shifted slightly through 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.
Can I just put seeds in the ground?
If the soil isn't cold and frozen, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope 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.
Should I 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 first before you transplant them. Hardening allows your seedlings to adjust to outdoor life and the fluctuating spring weather, 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 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 mounding a volcano of dirt around your plant, 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 cucumbers and eggplant, 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.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Plan your garden to make the most of your time and space. Don't forget to clean the shed and sweep out the gazebo in preparation for spring, too. No matter which plants you need and what outdoor projects you choose to tackle, you'll find that The Garden Center in Covina is the local plant nursery to help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing you should know 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 growing 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 8 garden can support plants listed as Zones 1–8. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. Be sure to read your seed packet for details. If you start plants later than recommended, it's not ideal, but it will 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 vegetables and herbs. Native plants like succulents, cacti, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat, like squash, tomatoes, cucumbers, 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 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. Look into house plants and create an oasis inside your home. A sunroom or covered porch is a great place to encourage plant growth, especially with pots and plant stands of all sizes. Your spring flower seed choices, 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 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 a spray bottle of water, good soil, and patience. Then you have everything you need to try 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. That way, you'll know where your seeds should pop up, and you can be sure 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 inch-tall micro-seedlings are fragile but resilient. Seedlings don't get all this pampering in nature, 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 a couple of 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 at 50 degrees or above at night. Cover your plants if they're in the ground when a late-season frost sneaks back in.
Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a tag so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by rodents or deer, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.
Protect Your Garden With Mulch
Finish your planting by following it with compost and mulch. Mulch keeps your soil moist and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster stronger and 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
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 a pellet grill or artificial grass to your outdoor space. Shop for the seeds, soil, and fertilizer you need in the aisles of your Covina Garden Center, online, or on our mobile app. Let's get growing together.
