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

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 into blocks by climate. Find your zone on the USDA plant hardiness 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 plants later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
Puerto Rico is in Zones 12 and 13, with the highest mountain peaks coming in at 11B. Your climate is excellent for growing year-round if you've got rich soil. Why not think of springtime planting now? 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. 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.

Fruit like pineapple, mangoes, guava, coconuts, plantains, and starfruit thrive in Puerto Rico's tropical climate. Roots like cassava, taro, and yams grow well, too. Hot peppers thrive here, and you can try bell peppers or the more heat-loving variety of cubanelle peppers. Veggies in the squash family, like cucumbers, pumpkins, and calabaza squash also enjoy the weather. You may want to look into shade sails or another shade structure to give your garden a break from the intense humidity and heat. The sun is so strong here that the full sun recommendation that works on the continental U.S. might be too harsh here. Hydroponics, container gardening, or potted plants give you extra flexibility to control the amount of shade and sun 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. For best results, you'll want grow lights or a warming mat to go with your seed tray or planters. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Carolina Garden Center — to make it easy to stay organized and plant tiny soil plugs later. 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 toothpick or plant tag. 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 they please, 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
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. Bring them inside or move them to a shady spot if they're looking rough. As always, make sure they're watered enough. Whisk wilted plants inside and give them a good drink, making sure they're strong before returning them outdoors.

Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. A good way to do this is to turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, leave plenty of room around the stem and dig deeper than you think with your garden trowel. You don't want to damage the root ball. Put the plant in the hole and ensure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish it all off with compost and mulch. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger plants that bear more flowers and fruit. 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 right amount.
