Frequently Asked Questions About Gardening
How do I know what planting zone I'm in?
Check the USDA plant hardiness zone map, as planting zones have shifted 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 gardening success.
What does direct sow mean?
If the soil isn't frozen or cold, consider planting your fruit, veggie, or flower 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 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 is the process of getting them used to the great outdoors and rain, sun, 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 information.
How do I strengthen my seedlings before planting them outdoors?
Get your sprouts used to storms and breezy spring days with a fan and keep fungus from growing in damp conditions. Set up an oscillating floor fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick. The stems and leaves will get used to blowing in the breeze and not snap when a gust comes through. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.
What are seed tapes?
If you're dealing with extremely tiny seeds or want more guidance in planting, 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
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for warmer temperatures, fragrant breezes, and sprouts poking up out of the ground. 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 learn when planting spring flowers, vegetables, 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. For best results, choose plants in your zone number or less. In other words, a Zone 6 garden can support plants listed as Zones 1–6. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Read your seed packet for details. If you start them a little 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 cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like squash, tomatoes, peppers, and cucumbers. 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 varieties that can handle the weather before planting outdoors.
An indoor garden of greenery might be lovely as well. Look into house plants and create an oasis inside your home. A covered porch or sunroom 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 perennials or annuals, can also often get an indoor start.
Start Seeds Indoors
Save money when you grow your garden from seeds by starting them indoors in your own seedling garden. 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. 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 toothpick or plant tag. That way, you'll know where your seeds should pop up. 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, 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 fan on low to mimic the wind and strengthen their stems.
Harden Your Seedlings
Once your seedlings have sprouted and are a few inches tall, start hardening them off. This is a process of gradually introducing them to the outdoors, making them stronger in the long run. Hardening means you're less likely to lose your growing garden during a sudden cold snap.
Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then give them a generous drink of water — without drowning it. Blanket the surrounding ground with mulch, marking where the plant is with a tag so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if deer or rodents visit your yard regularly, as your sprouts may otherwise become a snack.
Protect Your Garden With Mulch
Finish your garden bed 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 fruit and flowers. 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. Prepare to fertilize your lawn, plan your garden and landscaping, and browse The Home Depot nursery to find inspiration on what 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, fertilizer, and soil you need in the aisles of your Monrovia Garden Center, online, or on our mobile app. Let's get growing together.
