Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, as well. Plan your garden to make the most of your time and space. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. No matter what outdoor projects you choose to tackle, The Garden Center in Rialto can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing you should 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 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. 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 6 garden can support plants listed as Zones 1–6. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will 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 beautiful 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 climate and weather make it easy to get and keep a beautiful garden. A wide variety of flowers, veggies, and plants 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 heat levels and colors, including jalapeños, bell peppers, and more. Cucumbers, zucchini, squash, and pumpkins, which are direct sow only, will flourish. Planting tomatoes will yield thriving fruit and leaves, as they’re tropical in origin and love the heat.

In the desert, native plants like succulents, cacti, and other hardy desert shrubs will grow outside with ease. 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. However, many flowers are sensitive to that much heat and sun, so research to find which varieties can handle the weather before planting outdoors.

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 trays or pots are prepared, plant your seeds. As for the soil, test the mineral levels and pH to find if it needs additives or amendments. Soil pH differs among regions, and what your plants need depends on what you're growing. Most veggie plants like a pH of around 6.5. Soil amendments can tip the balance of your soil in a direction that'll help your plants.

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 micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're 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
Harden your seedlings for strong plants. On days above 45 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for a couple of hours, but bring them inside at night. They're not ready for direct sunlight yet or harsh nighttime temps. Gradually add an extra hour or two 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
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 roots. Place it into the hole you dug for it, even with the surrounding soil.

Protect Your Garden With Mulch
Finish your flower bed 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 flowers and fruit. Mulch keeps your soil moist and controls weeds. 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
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 what to plant when the weather warms. Shop for the soil, fertilizer, and seeds you need in the aisles of your Rialto Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA plant hardiness zone map, as planting zones have shifted slightly through the years. Planting 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 does direct sow mean?

If the soil isn't frozen or cold, consider planting your fruit, veggie, or flower 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 envelope for how and when to sow seeds.

Do you carry organic seeds and plants?

Yes, we've got a variety of organic options, including organic veggie seeds and fruit 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.

Should I harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them before you transplant them. Hardening is the process of getting them used to the great outdoors and rain, sun, and temperature swings. 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. Read your seed packets or speak to a garden center associate for more information.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to storms and breezy spring days 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. 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 want more guidance in planting or are dealing with extremely tiny seeds, 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, your perfectly spaced sprouts will pop up soon.
