Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA zone map, as planting zones have shifted slightly through 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 does direct sow mean?

If the ground isn't frozen solid and the soil isn't cold, consider planting your flower, fruit, 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 sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed package for how and when to sow seeds.

How do I plant flower seeds?

Follow the instructions on your seed packet. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add three to five seeds per planting hole, then push them down with your finger. Mark where you planted them with a flag, twig, or toothpick so you don't think they're weeds later.

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 is the process of getting them used to the great outdoors. 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 prepare for planting transplants or seeds outside?

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

The Home Depot Garden Center at S Olathe

No matter what outdoor projects you choose to tackle, The Garden Center in S Olathe can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, vegetables, 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 plant bell pepper seedlings 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 9 garden can support plants listed as Zones 1–9. 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 later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
Much of the Great Plains and Upper Midwest is in Zones 3 through 5. Your best bets for veggies will be root vegetables like beets and carrots, leafy greens including lettuce, and cruciferous veggies like broccoli and kale. You can try squash, too. If you plant outside, prepare for additional warming upkeep when late frost is forecast. Planting dates are similar to Zone 4, that is to say, the target is mid-March through May 1st, depending on whether you’re starting your seeds indoors or directly sowing them into your garden.

The state of Kansas and slightly north of the state line is in Zone 6, so planting can begin earlier there than farther north. The outdoor growing season doesn’t kick off until mid-March or even April, although you can start some veggies by seed halfway through February. Tomatoes, peppers, cucumbers, squash, onions, and other classic garden crops will do well in this region, and most of them can get an early jump on growing indoors before spring really moves in.

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 pouch 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, rodents and insects that crave tender greens, and sudden cold temperatures. 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 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
Carefully take your seedling out of the container. Turn it sideways or upside-down and gently squeeze the plastic to break the seal. If your transplant grew in the garden, dig deeper than you think with your garden trowel and leave plenty of room around the stem. You don't want to damage the root system. Put the plant in the hole and make sure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish your flower bed with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more flowers and fruit. Mulch keeps your soil moist and controls weeds. 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 perfect 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 seeds, soil, and fertilizer you need in the aisles of your S Olathe Garden Center, online, or on our mobile app. Let's get growing together.
