Frequently Asked Questions About Gardening

What planting zone am I in?

Check the USDA growing zone map, as planting zones have changed slightly 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.

What's direct sow?

If the soil isn't frozen or cold, consider planting your fruit, flower, or veggie 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 package for when and how 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, and organic herb and flower seeds that are subject to availability. We carry the organic soil to plant it in as well as the organic fertilizer to feed it.

Should I harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, 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. Speak to a garden center associate or read your seed packets 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. 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 island in a puddle of water, and don't pack 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 alike. 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.

The Home Depot Garden Center at Upland

On those beautiful days, clean up the yard before everything blooms in earnest. Many people feel inspired to refresh their outdoor space for entertaining, as well. Planning your garden lets you make the most of your time and space. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. No matter what outdoor projects you choose to tackle, The Home Depot Upland Garden Center can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, veggies, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted into blocks 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, and all the zones numbered less than that. In other words, a Zone 5 garden can support plants listed as Zones 1–5. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Read your seed packet for details. If you start plants a little 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 San Bernadino and Palm Springs. A temperate Mediterranean climate on the coast means it’s usually gorgeous gardening weather and excellent for growing. 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. The weather and climate make it easy to get and keep a beautiful garden. A wide variety of plants, flowers, and veggies 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 bell peppers, jalapeños, 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 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 sun and heat, so research to find varieties that 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 space and reliability as starting indoors. However, if you like to go with the flow, follow the instructions on your seed package and try it.

Prepare to deal with whatever hand nature deals you: Be ready for none of your seeds to sprout, all of them to come up, and anything in between. Your seedlings will need to survive rain, wind, bugs and critters that want a crunchy green snack, and sudden cold snaps. 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 instead. 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 sunlight and rain. Keep your seeds warm with warming mats and grow lights, water them carefully with a spray bottle 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
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a stick or 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 rabbits, squirrels, deer, or chipmunks visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish it all 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 stronger and larger plants that bear more flowers and fruit. Mulch and compost 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 right amount.

Greet the Spring
Early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your Upland Garden Center, online, or on our mobile app. Let's get growing together.
