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. 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 is warm and pliable, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope 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, 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.
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.
How do I prepare for planting seeds or transplants outside?
Before you plant, make sure that your plant will have the right amount of sun, it's warm enough outside, and the soil is healthy. 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 on the seed envelope for best results so your plant babies have room to grow big and strong.
Should I use peat moss starters or coir starters?
Seed starters, full of nutrients in 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 cucumbers and eggplant, 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.

Set Up For Springtime
It's time to start thinking of spring. Sweep out the gazebo and clean the shed 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 spring flowers and young veggie plants when the ground thaws and the frosts are through. You might even want to sow 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 you should 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 growing 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 — plus all the zones numbered less than that. In other words, a Zone 7 garden can support plants listed as Zones 1–7. 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 seeds 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 vegetables and herbs. Native plants like cacti, succulents, and other hardy desert shrubs will easily grow outside. 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 flowers are sensitive to that much heat and sun, 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 within your home. A sunroom or enclosed porch 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 annuals or perennials, can also often get an indoor start.
Start Seeds Indoors
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. For best results, you'll want warming lights or a warming mat to go with your seed tray or plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Pasadena Garden Center — to stay organized and plant tiny soil plugs when the time comes. You can also use pots with potting soil and seed starter mix.
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 plant tag or toothpick. 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 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
Make sure to harden your seedlings for strong plants. On days that are warmer than 45–50 degrees, take your pots or trays of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. They're not ready for direct sunlight yet or harsh nighttime temps. Gradually add more outside time each day, gently introducing your plants to the sun. After a week or more of this, you can leave them out overnight if the temps stay warmer than 50 degrees. Cover your plants if they're in the ground when a late-season frost sneaks back in.
Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Blanket the surrounding ground with mulch, marking where the plant is with a 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 it all off with compost and mulch. 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 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 right amount.
Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Plan your garden and landscaping, prepare to fertilize your lawn, 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 balcony or patio. Shop for the seeds, soil, and fertilizer you need in the aisles of your Pasadena Garden Center, online, or on our mobile app. Let's get growing together.
