Frequently Asked Questions About Gardening

How do I check my USDA planting zone?

Check the USDA plant hardiness zone map, as planting zones have shifted slightly through the years. Zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of successful gardening.

When can I plant seeds in my garden?

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

Do you carry organic plants and seeds?

We offer many organic gardening 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 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. Speak to a garden center associate or read your seed packets for more information.

What do I do before planting seeds or transplants outside?

Before you plant, make sure that your plant will have the right amount of sun, the soil is healthy, and it's warm enough outside. Check your seed envelope to see if it likes shade, full sun, or partial sun, as well as what time of year it should be planted. Space your plants as described on the seed package 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, you'll have perfectly spaced sprouts pop up soon.

Don't forget to sweep the gazebo and clean out the shed in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, search for your local plant nursery and find that The Garden Center in Colma II can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to learn when planting veggies, spring flowers, 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 transplant bell peppers outdoors in mid-March in Zone 10, but not until the end of May in Zone 4. For best results, choose plants in your zone number or less. In other words, a Zone 5 garden can support plants listed as Zones 1–5. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. 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
This region ranges from 7–9, with higher elevations in Zones 5 and 6. You'll find fertile land in some places, but deserts 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 succulents, cacti, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like tomatoes, peppers, cucumbers, and squash. 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 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 pack 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 wind, rain, and cold snaps, as well as critters and bugs that want a crunchy green snack. 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 in your own plant nursery. 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 cozy with warming mats and grow lights, water them carefully with a mister 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. Blanket the surrounding ground 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. If your yard is regularly visited by rodents or deer, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.

Protect Your Garden With Mulch
Finish off your garden with mulch and compost. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. 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 what to plant when the weather warms. For those without lawns, consider adding an outdoor rug, artificial grass, or a pellet grill to your patio or balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your Colma II Garden Center, online, or on our mobile app. Let's get growing together.
