Choosing Your Seeds: What to Know Before You Start

Before you plant a single seed, you need to choose the right type of seed for your climate and growing season. Look at the back of the seed packet to find information about when to start seeds indoors, how deep to plant seeds, and when to direct sow seeds outdoors.

• Know when to start: The general rule of thumb is to count backwards from your area's last frost date, as most seeds need to be started 4–10 weeks prior to transplanting outside.
• Consider the growing season and if the soil is warm enough when you plan to direct sow.
• Choose seeds suited to your garden soil and conditions.

Understanding the temperature range and light requirements that your seeds need will also help you set up the right indoor environment.

Preparing Your Seed Starting Supplies

Successful seed starting begins with having the right tools on hand. Here’s a list of essential seed starting supplies and why each is important.

Seed Starting Tray and Containers

• Use a dedicated seed starting tray with holes in the bottom for drainage.
• Peat pots, small plastic cells, or soil blocks also work. Make sure they’re clean to avoid disease.
• Place trays in a warm spot or on a heat mat if your home is cool.

Seed Starting Mix

• Use a good seed starting mix, not garden soil. A mix of peat, compost, and vermiculite offers better drainage and helps seeds germinate.
• Avoid garden soil which can compact and harbor pathogens.

Seed Starter Tools

• Humidity dome to help keep the soil moist while seeds germinate.
• Labels or markers to keep track of what you planted.
• A spray bottle for gentle watering.

How to Sow Your Seeds Indoors: Step-by-Step

Step 1: Prepare the Soil

Fill your seed starting tray or pots with moistened seed starting mix. The soil should be damp but not soggy.

Step 2: Sow Seeds

• Check the seed packet for how many seeds per cell to sow and how deep to plant.
• As a general rule of thumb, plant the seed at a depth about twice the diameter of the seed.
• Lightly press the top of the soil to ensure good contact.

Step 3: Keep Moist and Warm

• Cover with a humidity dome and place in a warm location or use a heat mat to maintain the correct temperature range.
• Avoid letting the soil dry out during germination.

Providing Light and Heat for Healthy Seedlings

Light and warmth are crucial for seedlings to emerge from the soil strong and healthy.

Grow Lights and Good Light

• Place your seed starting tray in a south-facing window if possible.
• If natural light isn’t strong enough, use a grow light placed 2–4 inches above the seedlings for 12–16 hours a day.
• Rotate trays so seedlings get even light and don’t lean.

Heat Mats

• Many seeds, especially peppers and tomatoes, benefit from the use of a heat mat during seed germination.
• Heat mats help keep the soil warm enough, speeding up germination and creating healthy seedlings.

Watering and Caring for Seedlings

Bottom Watering

• To prevent disease and ensure roots absorb moisture, use bottom water by placing the tray in a shallow pan of water.
• Allow the soil to soak until moist but not soggy, then remove the tray.

Thinning

• Once true leaves appear (the second set of leaves after the first sprouts), thin seedlings to avoid overcrowding.
• Keep only the strongest plants in each cell or larger pot.

Air Circulation

• A gentle fan can help strengthen stems and reduce the risk of fungal diseases.

When and How to Transplant Seedlings Outdoors

Once your seedlings have developed a strong root system and have at least one set of true leaves, it’s time to prepare them for the garden.

Hardening Off

• About one week prior to transplanting outside, start taking your seedlings outdoors for a few hours each day.
• Gradually increase exposure to sun, wind, and cooler temperatures to acclimate them.

Transplanting

• Make sure the soil is warm enough and there’s no risk of frost.
• Water seedlings well before moving them into the garden soil.
• Dig holes large enough to fit the roots without crowding and gently plant the seeds 2–3 inches deeper for tomatoes and similar plants.

Best Practices and Troubleshooting

Common Seed Starting Challenges

• Seeds not germinating? Check temperature, moisture, and the back of the seed packet for guidance.
• Leggy seedlings? Move them closer to a good light source or lower your grow light.
• Mold or damping-off? Increase air circulation and avoid overwatering.

Tips for Success

• Keep the soil consistently moist but not soggy.
• Choose the right potting mix and avoid garden soil.
• Pay attention to frost dates and the time to start seeds indoors.

Advanced Techniques: Soil Blocking and Direct Sow

For gardeners who want to go beyond seed starting 101, here are two advanced methods:

Soil Blocking

• Instead of using pots, form blocks of soil mix and plant one seed per block. This promotes strong root systems and eliminates transplant shock.

Direct Sow

• Some seeds, like carrots and beans, prefer to be direct sown into the garden soil once the soil is warm enough.
• Check the seed packet to determine whether to start your seeds indoors or sow directly.

FAQs about Seed Starting 101

When should I start seeds indoors?

It depends on your local last frost date and the type of seed you’re planting. A general rule of thumb is to start seeds indoors 4–10 weeks before the last expected frost. Always check the back of the seed packet for the recommended timing.

What is the best seed starting mix to use?

A good seed starting mix is light, well-draining, and designed to hold just enough moisture without compacting. Avoid using garden soil, which can be too heavy and may harbor disease. Look for mixes that include peat, compost, and vermiculite.

Do I really need a grow light for seed starting?

If you don’t have a south-facing window with strong light, a grow light is highly recommended. Seedlings need 12–16 hours of bright light per day to avoid becoming leggy and weak.

How do I know if my seeds have germinated?

Once you see small sprouts emerging from the top of the soil, your seeds have germinated. Look for the first set of leaves, and then the true leaves, which are a sign your seedling is growing strong.

What is the best way to water seedlings?

The best practice is to bottom water by placing your seed starting tray in a shallow pan of water and letting the soil absorb moisture from below. This helps prevent overwatering and keeps the surface dry to reduce disease risk.

When is it time to transplant seedlings outdoors?

You can transplant seedlings when they have at least one set of true leaves, the soil is warm enough, and all risk of frost has passed. Don’t forget to harden off your seedlings by gradually introducing them to outdoor conditions before planting them in the garden.

Do all seeds need to be started indoors?

Not all. Some seeds are best sown directly into the garden soil when it’s warm enough. Check the seed packet to see if the plant prefers direct sowing or indoor seed starting.
