It's time to start thinking of spring. We're here to help you prepare for fragrant breezes, sprouts poking up, 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 frosts are through and the ground thaws. You might even want to directly plant organic seeds into the earth.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, veggies, 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 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 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. Be sure to read your seed packet for details. If you start plants a little later than recommended, it's not ideal, but it will even out as time passes.

Gardening in Your Growing Zone
Hawaii's growing zones range from 9 to 12, with a few areas of Zone 13. Your climate is excellent for growing year-round if you've got rich soil. Why not think of springtime planting now, while it’s technically meteorological winter? With such beautiful weather, you can direct sow many types of seeds. Your garden might still be growing if there's no reason to put it to bed. In that case, tend it as usual.

Some seeds, like tomatoes, do best when started indoors and aren't recommended as direct sows, so read your seed packets and adjust accordingly for your region. Plantains, coconuts, and bananas thrive in Hawaii's tropical climate. Roots like yams, taro, and tapioca grow well, too.

Hot peppers thrive here, and you can try bell peppers. Veggies in the squash family, like cucumbers and pumpkins, also enjoy the weather. If your temps regularly get over 90s, look into shade sails or another shade structure to give your garden a break from the humidity and intense heat. 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 and gain the satisfaction of growing 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 warming lights or a warming mat to go with your seed tray or planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Pearl City 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
Prepare your seed sprouts for outdoor life while they're still indoors. These micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings 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 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 is a process of gradually introducing them to the outdoors, making 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
Carefully take your seedling out of the container. Turn it upside-down or sideways 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 ensure it's even with the surrounding soil.

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