Frequently Asked Questions About Gardening

How do I know what planting zone I'm in?

Check the USDA planting zone map, as planting zones have changed slightly 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 in gardening?

If the ground isn't frozen solid and the soil isn't cold, consider planting your flower, veggie, or fruit 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.

How do I plant seeds?

Read your seed envelope for info on proper depth, spacing, and how many seeds to sow per hole when planting fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary from one type of plant to the next. Certain seeds should only be planted indoors, and your seed package will tell you that, too. For more details, check out how to grow a garden from seed.

Do I have to harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening allows your seedlings to adjust to outdoor life, spring rains, and temperature swings, 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.

What should I do before planting seeds or transplants outside?

Before you plant, make sure that the soil is healthy, it's warm enough outside, and your plant will have the right amount of sun. Check your seed package to see if it likes shade, partial sun, or full 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 flourish.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient 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 carrots and beets, 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.

Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, as well. Plan your garden to 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 Garden Center in Signal Hill can 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 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. 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. Always read your seed packet for details. If you start plants a little later than recommended, it's not ideal, but it will likely 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 herbs and vegetables. Native plants like cacti, succulents, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat, like cucumbers, squash, 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 sun and heat, so research to find which varieties can handle the weather before planting outdoors.

An indoor garden of greenery might also be lovely, so create an oasis inside your home. A sunroom or enclosed 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 perennials or annuals, can also often get an indoor start.

Plant Seeds Outside With Direct Sow
Planting seeds with the direct sow method, right into the soil, is another 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.

Your seeds might get washed away or struggle to grow, or insects or rodents might eat the sprouts. But if you're really fortunate, you might get strong sprouts, perfectly spaced and ready to grow all spring. The reality of your sown seeds will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are primed to survive and hardy, although there are no guarantees in the long term.

Start Seeds Indoors
If you're eager to get growing or would like more control in the care and feeding of seedlings, 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 heat 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
When your plants have three or four real leaves — different from miniature seedling leaves – transplant them. In quality soil, dig a hole that's the same size as the dirt plug where your transplant has been growing. If your ground soil isn't great, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply fertilizer as directed, either on top of the soil after it's planted or in the hole. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.

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 larger and stronger plants that bear more flowers and fruit. 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
Early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the seeds, fertilizer, and soil you need in the aisles of your Signal Hill Garden Center, online, or on our mobile app. Let's get growing together.
