Frequently Asked Questions About Gardening

What's my planting zone?

Check the USDA 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.

Can I plant seeds directly in the ground?

If the ground isn't frozen solid and the soil isn't cold, consider planting your veggie, flower, or fruit seeds directly into your garden. This is called the "direct sow" method. Plant 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 when and how to sow seeds.

Do you carry organic plants and seeds?

We offer many organic gardening options, including organic fruit seeds and veggie seeds, and organic flower and herb seeds which are subject to availability. We carry the organic soil to plant it in as well as the organic fertilizer to feed it.

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

Yes, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening is the process of getting them used to outdoor life and the fluctuating spring weather. 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.

How do I plant a transplant or baby plant?

Squeeze the plastic around the plant to loosen the soil. Carefully coax the plug of dirt with the plant into your palm, then place it into the hole you dug for it. Make sure the top of your transplant's soil is even with the garden soil, and carefully press the earth into place. Avoid mounding a volcano of dirt around your plant, and don't pack the ground too tightly. Your plant baby needs to breathe.

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.

Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, fragrant breezes, and sprouts poking up out of the ground. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring flowers 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 you should 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 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. Be sure to read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
The southernmost part of California is primarily in Zones 9 and 10, with small areas of 6–8 sprinkled in near Palm Springs and San Bernadino. A temperate Mediterranean climate on the coast means there's usually gorgeous gardening weather. Areas in the mountains and desert are more challenging to grow vegetables in, but indoor gardening is an excellent workaround.

For more temperate areas, find your planting zone and prepare to get planting. Growing season begins early and ends late in this part of the country. The weather and climate make it easy to get and keep a beautiful garden going. A wide variety of plants, flowers, and veggies thrive in southern California. You can even grow citrus trees for fresh fruit when you plant somewhere with good soil drainage. You’ll have excellent results with peppers of all colors and heat levels, including bell peppers, jalapeños, and more. Cucumbers, zucchini, squash, and pumpkins, which are direct sow only, will flourish. Planting tomatoes will yield thriving leaves and fruit, as they’re tropical in origin and love the heat.

In the desert, native plants like succulents, cacti, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat. If you start them indoors and carefully introduce them outdoors in the shade, you can enjoy raising vegetables even in a dry climate. Compatible spring flower seeds, whether they're annuals or perennials, can also often get an indoor start.

Plant Seeds Outside With Direct Sow
Planting seeds with the direct sow method, right into the soil, is another option. It doesn't give you as much organized planning in terms of space and reliability as starting indoors. However, if you like to go with the flow, follow the instructions on your seed pouch and try it out.

Your seeds might get washed away or struggle to grow, or critters or insects might eat the sprouts. But if you're really fortunate, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your garden will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are hardy, although there are no guarantees.

Start Seeds Indoors
If you're eager to get growing or would like more control in the care and feeding of seedlings, 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 sun and rain. Keep your seeds cozy with heat 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
By now, your plants have 3 or 4 true leaves — they'll look different from the miniature seedling leaves. When you're not expecting soaking rain, and the ground is warm, look into transplanting your small plants 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 directly planted into the ground, 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 larger plants that bear more flowers and fruit. Mulch keeps your soil from drying out 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
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 soil, seeds, and fertilizer you need in the aisles of your Ontario, CA Garden Center, online, or on our mobile app. Let's get growing together.
