Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA growing 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 in gardening?

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 envelope for when and how to sow seeds.

How do I plant fruit seeds?

The best source of information is the seed packet your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary from one type of fruit, flower, or veggie 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 plant flower seeds.

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

Yes, if you raised plants indoors from seeds, harden them 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.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating floor fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick — no need to prep them for a hurricane. They'll gain strength even though you shouldn't see them moving. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

What are seed tapes?

If you're dealing with extremely tiny seeds or want more guidance in planting, 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.

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

Plant Hardiness Zones Explained
The first thing to 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 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 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. Read your seed packet for details. If you start plants later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
Your climate is excellent for growing year-round if you've got good soil. Why not think of springtime planting now? With such beautiful weather, you can direct sow many types of seeds. From classics like peppers and cucumbers to strawberries, green beans, and spinach, you have a wide variety of options. Your garden might still be growing if there's no reason to put it to bed — especially if it's close to the house or in a greenhouse. In that case, tend it as usual.

Some seeds, like tomatoes, do best when started indoors and aren't recommended as direct sows. Read your seed packets and adjust accordingly for your region. Although the warm temps are excellent for growing, check your soil to make sure it's rich enough and a good match to your plants. Sandy soil and Miami limestone will need soil amendments to adjust the texture and pH for a successful garden if you're growing many garden plants. If you go with native plants like persimmons, muscadines, red mulberries, and blueberries, they're already adapted to the soil of southern Florida and will grow just fine.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. Veteran planters and new gardeners alike should disinfect seed trays with a watered-down bleach solution before reusing them each year. When your pots or trays are prepared, plant your seeds. As for the soil, check to see if yours needs nutrient balancing. Choose fertilizers that match what you're growing. It'll help give your plants everything they need to grow big and strong.

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. That way, you'll know where your seeds should pop up. 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 certainly don't get all this pampering in nature when they volunteer and grow wherever, 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
Once your seedlings have sprouted and are a few inches tall, start hardening them off. This process of gradually introducing them to the outdoors makes them stronger in the long run. Hardening means you're less likely to lose your growing garden during a sudden cold snap.

Transplant Young Plants Into Their New Homes
By now, your plants have 3 or 4 true leaves — they'll look different from the miniature seedling leaves. When the ground is warm, and you're not expecting soaking rain, look into transplanting your big sprouts into their new outdoor home. "Transplant" means that you put these small plants straight into the garden soil or into pots. In cases where you direct sowed, you may still want to shuffle plants around for the best spacing and sun. That's also a transplant situation, as is repotting plants into larger pots.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more fruit and flowers. Mulch controls weeds and keeps your soil from drying out. Compost and mulch can be purchased in-store or created at home. 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. 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 which spring flowers to plant when the weather warms. Shop for the seeds, soil, and fertilizer you need in the aisles of your Marathon Garden Center, online, or on our mobile app. Let's get growing together.
