Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA plant hardiness zone map, as planting zones have shifted over 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 ground isn't frozen solid and the soil isn't cold, consider planting your fruit, veggie, 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 seedlings and sprouts 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 seeds and plants?

Yes, we've got a variety of organic options, including organic veggie seeds and fruit seeds, as well as organic herb and flower 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. 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. Speak to a garden center associate or read your seed packets for more information.

How do I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick — no need to prep them for a hurricane. This makes them stronger against wind gusts. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pellets or pots, 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 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.

Set Up For Springtime
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for fragrant breezes, sprouts poking up, and warmer temperatures. Planting seeds indoors near a sunny window 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, The Home Depot Costa Mesa Garden Center?

Plant Hardiness Zones Explained
The first thing you should 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 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 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. 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
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 plants, vegetables, and flowers 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 colors and heat levels, including jalapeños, bell peppers, and more. Cucumbers, zucchini, 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 cacti, succulents, 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 flowers, both annuals and perennials, are sensitive to that much heat and sun, so research to find which varieties can handle the weather before planting outdoors.

Start Seeds Indoors
Save money when you 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 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, 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 certainly 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
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered enough but not drowning. Whisk wilted plants inside and give them a good drink, making sure they're healthy before setting them outdoors again.

Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. Turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, dig deeper than you think with your garden trowel and leave plenty of room around the stem. You don't want to damage the root ball. Place it into the hole you dug for it, even with the surrounding soil.

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 larger plants that bear more fruit and flowers. Mulch keeps your soil from drying out and controls weeds. Compost and mulch 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 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 which spring flowers to plant when the weather warms. For those without lawns, consider adding artificial grass, an outdoor rug, or a pellet grill to your patio or balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your Costa Mesa Garden Center, online, or on our mobile app. Let's get growing together.
