Frequently Asked Questions About Gardening

How do I check my USDA planting zone?

Check the USDA planting zone map, as planting zones have changed slightly over 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's direct sow?

If the ground isn't frozen solid and the soil isn't cold, consider planting your flower, fruit, or vegetable seeds directly into your garden. This is called the "direct sow" method. The time to plant will be after the threat of frost is gone for the season, as seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed packet for how and when to sow seeds.

How do I plant fruit seeds?

Follow the directions on your seed envelope. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add three to five seeds per planting hole, then push them down with your finger. Mark where you buried the seeds with a wooden craft stick, twig, or flag so you don't confuse them with weeds later.

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 allows your seedlings to adjust to outdoor life and the fluctuating spring weather, making them more resilient against cold snaps. It slows their growth until they're strong and ready to take off during a spring warm front.

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 leaving the plant as island in a puddle of water, and don't tamp down the ground too tightly. Your plant baby needs to breathe.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pellets or pots, work for new and experienced gardeners alike. You don't have to use these starters if you're planting in soil, but you may want to. Starting seeds in peat pots works best for delicately rooted plants like cucumbers and eggplant, as well as flowers that need acidic soil. Some people prefer coir starters instead, as they have a neutral pH. Check what type of soil your plants need to help narrow it down, and chat with a garden center associate if you need more info.

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 flowers and young veggie plants 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 vegetables, spring flowers, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted by climate. Find your zone on the USDA planting 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 5 garden can support plants listed as Zones 1–5. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Always read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
This area is in growing Zones 8 or 9, but it’s desert, so utilize greenhouses to grow vegetables and herbs. Native plants like cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like tomatoes, peppers, cucumbers, and squash. 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 sun and heat, so research to find varieties that can handle the weather before planting outdoors.

An indoor garden of greenery is also lovely, so create an oasis within your home. An enclosed porch or sunroom is a great place to encourage plant growth, especially with plant stands and pots of all sizes. Your spring flower seed choices, whether they're perennials or annuals, 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 reliability and spacing compared to indoor starts. However, if you like to go with the flow, follow the instructions on your seed package and give it a try.

Your seeds might struggle to grow or get washed away, 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 in the long term.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, 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 rain and sun. Keep your seeds warm with warming 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
You've raised your baby plants from seeds, watched them sprout, and carefully hardened them off to brave Mother Nature. By now, your plants have three or four real leaves — they'll look different from the miniature seedling leaves. When the ground is warm, and you're not expecting soaking rain, look into transplanting your small plants into their new outdoor home. These large seedlings that are ready to be planted can also be called "transplants" or "starts." In cases where you direct sowed, 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 it off with compost and mulch. Mulch keeps your soil moist and controls weeds. 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.

Greet the Spring
Early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the seeds, soil, and fertilizer you need in the aisles of your Alhambra Garden Center, online, or on our mobile app. Let's get growing together.
