It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, and sprouts poking up, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring annuals 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 learn when planting spring flowers, vegetables, 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 plant bell pepper seedlings outdoors in mid-March in Zone 10, but not until the end of May in Zone 4. You'll have good results with plants that have your zone number or less. In other words, a Zone 6 garden can support plants listed as Zones 1–6. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Read your seed packet for details. If you start them later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
Your tropical climate is a sunny Zone 13 and excellent for growing year-round if you've got rich soil. With such beautiful weather, you can direct sow many types of seeds. From classics from strawberries to cucumbers and green beans to spinach, you have a wide variety of options.

Fruit like guava, papaya, mangoes, coconuts, and bananas thrive here. Roots like taro and yams grow well, and you may have good luck raising your own peppers. Eggplant and watermelon also love the tropical heat. Be sure to check that your veggies are heat-tolerant varieties that can take the high temperatures and humidity. Look into shade sails or another shade structure to give your garden a break from the intense heat and humidity. The sun is so strong here that the full sun recommendation that works on the continental U.S. might be too harsh here. Hydroponics, potted plants, or container gardening gives you extra flexibility to control the amount of sun and shade for best results.

Start Seeds Indoors
Save money when you 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 trays or pots 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 toothpick or plant tag. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
Prepare your seed sprouts for outdoor life while they're still indoors. 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden your seedlings for best results later. 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, incorporating a little sun to get your plants used to it. 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 and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
When your plants have three or four true 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 fantastic, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply any fertilizer as directed on the package, either in the hole or on top of the soil after it's planted. Don't apply more than recommended, as you could burn the plant and kill it instead of helping it along.

Protect Your Garden With Mulch
Finish your planting by following it 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 and larger plants that bear more fruit and flowers. Mulch and compost 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.
