Frequently Asked Questions About Gardening

How do I know what planting zone I'm 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's direct sow?

If the soil isn't frozen or cold, consider planting your flower, fruit, 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 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 seeds and plants?

We offer many organic gardening options, including organic fruit seeds and veggie 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 first before you transplant them. Hardening is the process of getting them used to outdoor life, spring rains, 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.

What should I check before planting seeds or transplants outside?

Before you plant, make sure that it's warm enough outside, the soil is healthy, and your plant will have the right amount of sun. Check your seed package to see if it likes full sun, shade, or partial sun, as well as what time of year it should be planted. Space your plants as described for best results so your plant babies have room to grow big and strong.

What are seed tapes?

If you want more guidance in planting or are dealing with extremely tiny seeds, 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, your perfectly spaced sprouts will pop up soon.

The Home Depot Garden Center at Martinez

It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, and sprouts poking out of the ground, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring annuals when the frosts are through and the ground thaws. You might even want to directly plant seeds into the earth.

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. 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 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Be sure to read your seed packet for details. If you start them later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
This region ranges from 7–9, with higher elevations in Zones 5 and 6. You’ll find fertile land in some places, desert and mountains with harsher conditions elsewhere. What you can grow and when will vary considerably depending on where you live. In Zones 5 and 6, the outdoor growing season doesn’t begin here until mid-March or even April, although you can start some veggies by seed halfway through February. Warmer Zones 7–9 can plant earlier, but if you’re in the desert, you’ll likely want to investigate indoor gardening in a sunroom or enclosed porch.

Utilize greenhouses to grow herbs and vegetables. Native plants like cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like squash, cucumbers, tomatoes, 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 heat and sun, 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. There's less planning and tending than growing indoors. If you like to go with the flow, follow the instructions on your seed pack and try it.

Prepare to deal with whatever hand nature deals you: Be ready for all your seeds to sprout, none of them to come up, and anything in between. Your seedlings will need to survive wind, rain, critters and bugs that crave tender greens, and 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 rain and sunlight. 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 tag or stick 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 your flower bed with compost and mulch. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger plants that bear more fruit and flowers. 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 which spring flowers to plant when the weather warms. Shop for the seeds, fertilizer, and soil you need in the aisles of your Martinez Garden Center, online, or on our mobile app. Let's get growing together.
