When you're ready to seed your lawn, our calculator helps you estimate the amount of grass seed you'll need to get the job done.
Enter your preferred material, the square footage and mulch depth of the coverage space for accurate results.
We'll calculate the amount of fencing you should purchase based on your property needs.
What planting zone am I in?
Check the USDA plant hardiness zone map, as planting zones have shifted over the years. Planting zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of gardening success.
Is it ok to plant seeds outside?
If the soil isn't cold and frozen, consider planting your veggie, fruit, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed packet for when and how to sow seeds.
How do I plant vegetable seeds?
Follow the advice on your seed envelope. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add several seeds per planting hole, then press them into the soil at the correct depth. Mark where you planted them with a flag, toothpick, or twig so you don't mistake them for weeds later.
Should I harden off my seedlings before planting them outside?
Yes, if you raised plants indoors from seeds in your own plant nursery, 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.
What do I do before planting seeds or transplants outside?
Before you plant, make sure that the soil is healthy, your plant will have the right amount of sun, and it's warm enough outside. Check your seed packet to see if it likes shade, partial sun, or full sun, as well as what time of year it should be planted. Space your plants as described on the seed envelope for best results so your plant babies have room to grow big and strong.
Should I use peat moss starters or coir starters?
Seed starters, full of nutrients in convenient pots or pellets, 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 carrots and beets, as well as flowers that require an acidic pH. 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.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. Don't forget to clean the shed and sweep out the gazebo in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, search for your local plant nursery and find that The Garden Center in El Cerrito can help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing to learn 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. For best results, choose plants in 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. Read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it should even out as time passes.
Gardening in Your Growing Zone
This region ranges from 7–9, with higher elevations in Zones 5 and 6. You'll find fertile land in some places, but deserts and mountains with harsher conditions elsewhere. What you can grow and when will vary considerably depending on where you live. In Zones 5 and 6, the outdoor growing season doesn't begin here until mid-March or even April, although you can start some veggies by seed halfway through February. Warmer Zones 7–9 can plant earlier, but if you're in the desert, you'll likely want to investigate indoor gardening in an enclosed porch or sunroom.
Utilize greenhouses to grow herbs and vegetables. Native plants like cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like tomatoes, squash, peppers, and cucumbers. 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, both annuals and perennials, are sensitive to that much sun and heat, so research to find which varieties can handle the weather before planting outdoors.
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 packet and try it.
Your seeds might struggle to grow or get washed away, or bugs or animals 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 in your own plant nursery. 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
Carefully take your seedling out of the container. A good way to do this is to turn it sideways or upside-down 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. Put the plant in the new hole and ensure it's even with the surrounding soil.
Protect Your Garden With Mulch
Finish it off with compost and mulch. Mulch controls weeds and keeps your soil from drying out. 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 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.
Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Prepare to fertilize your lawn, plan your garden and landscaping, and browse The Home Depot nursery to find inspiration on which spring flowers to plant when the weather warms. For those without lawns, consider adding an outdoor rug, artificial grass, or a pellet grill to your patio or balcony. Shop for the fertilizer, seeds, and soil you need in the aisles of your El Cerrito Garden Center, online, or on our mobile app. Let's get growing together.
