Growing autumn sage from seeds is an easy and rewarding way to add this gorgeous plant to your outdoor space. In this comprehensive guide we’ll walk through each step of the process from choosing the right seeds to transplanting seedlings into the garden. Whether you’re a beginner or seasoned gardener, read on for pro tips to successfully grow autumn sage from seeds.

Choosing High Quality Autumn Sage Seeds

The first step is acquiring high quality autumn sage seeds to plant. There are a few things to look for when buying seeds:

• Reputable seller: Purchase from a reputable seller, either online or at your local nursery. Avoid random seed packets with unknown origins.

• Ideal variety Choose a variety suitable for your region’s climate Popular varieties like ‘Cherry Sage’ and ‘Furman’s Red’ are great choices

• Harvest date Seeds harvested in current or previous year are ideal Old seeds may not germinate well

• Organic: Opt for organic seeds when possible to avoid pesticide exposure.

Once you’ve found a good source for seeds, it’s time to get planting!

When to Plant Autumn Sage Seeds

Autumn sage can be planted either indoors or directly outside:

• Indoors: Start seeds indoors 6-8 weeks before your region’s last expected frost. This gives seedlings time to mature before being transplanted outdoors.

• Outdoors: Direct sow after any danger of frost has passed. This is usually early to mid spring.

• Fall planting: Seeds can also be planted in fall in warmer climates for earlier spring blooms.

Adjust timing accordingly based on your local climate and frost dates.

How to Plant Autumn Sage Seeds Indoors

Starting autumn sage inside allows you to give seeds the ideal conditions for germination. Here’s a simple step-by-step:

1. Prepare Seed Starting Mix

Use a quality seed starting mix rather than regular potting soil. Seed mix is finely textured and designed for seed germination.

2. Fill Containers & Plant Seeds

Fill seed trays or small containers with moistened soil. Gently press 1-2 sage seeds into the soil surface per cell, about 1⁄4 inch deep.

3. Cover and Water Trays

Cover trays with plastic dome lids to retain moisture. Keep soil moist, but not soaked. Remove lids once sprouts appear.

4. Provide Warmth & Light

Place trays in a warm spot (65-70°F) with plenty of light. South facing windowsills are perfect. Turn trays daily for even growth.

5. Transplant Outdoors

Once seedlings have 2-4 true leaves, harden off and transplant into garden beds after all danger of frost.

With the right care, you’ll have hearty autumn sage transplants ready for the garden!

How to Direct Sow Autumn Sage Outdoors

For those who prefer not to start seeds indoors, autumn sage can also be directly sown into outdoor beds once spring weather arrives. Follow these tips:

Choose a Sunny Spot

Select a location with at least 6 hours of full sun for the best growth and maximum blooms.

Prepare Soil

Prepare a planting bed by mixing in compost to enrich soil nutrients and drainage. Rake area smooth.

Sow Seeds & Cover Lightly

Sow seeds by sprinkling evenly over soil, then cover very lightly with 1⁄4 inch of fine soil or compost.

Maintain Moisture

Water gently to avoid washing away seeds. Keep soil moist, but not soaked until sprouts appear.

Thin Seedlings

Once seedlings reach 2-4 inches, thin to 12-18 inches apart to avoid overcrowding.

With proper sowing techniques, you’ll have autumn sage seedlings sprouting in garden beds in no time.

Caring for Autumn Sage Seedlings

Once seeds have successfully germinated, either indoors or out, there are a few key care tips to ensure healthy, vigorous growth:

• Water – Maintain even moisture in top few inches of soil. Avoid letting seedlings dry out or become waterlogged.

• Light – Ensure young plants receive ample sunlight. Supplement with grow lights indoors if needed.

• Fertilizer – Use a diluted liquid fertilizer once seedlings have true leaves. This nourishes growth.

• Space – Give each seedling sufficient room to grow as they mature. Thin or re-pot as needed.

• Hardening off – Gradually acclimate indoor seedlings to outdoor conditions before transplanting.

Following these simple seedling care guidelines will set your autumn sage transplants up for abundant blooms.

Transplanting Autumn Sage Seedlings

Once indoor grown autumn sage seedlings have 2-4 sets of true leaves and have been hardened off, they are ready for transplanting into the garden. Follow these tips:

• Timing – Transplant after the last spring frost when soil is warm. Early to mid spring is ideal.

• Spacing – Allow 12-18 inches between young plants to accommodate growth.

• Planting Depth & Method – Set transplants at the same level they were growing in pots. Plant carefully to avoid disturbing roots.

• Watering – Water thoroughly after transplanting and provide 1-2 inches of water per week during first year.

With proper transplanting, your seedlings will flourish into gorgeous, blooming plants as they mature.

Direct Sowing Autumn Sage Seeds in Fall

In addition to spring, autumn sage seeds can also be directly sown into garden beds in early fall in mild climates. This allows plants to establish before winter dormancy, resulting in earlier blooms the following season.

Follow the outdoor sowing guidelines above, but plant 8-10 weeks before your first expected fall frost. Make sure to select a hardy autumn sage variety suited for overwintering if sowing in fall.

Ongoing Care of Autumn Sage Plants

Once your autumn sage is fully established, either from transplants or direct sowing, here are some care tips to nurture growth:

• Sunlight – Continue providing a minimum of 6 hours of sunlight in the growing season.

• Watering – Water deeply once a week in first year, then reduce in subsequent years. Mature plants are quite drought tolerant.

• Fertilizer – Feed with a balanced fertilizer or compost each spring to promote lush growth.

• Pruning – Prune lightly after flowering to remove dead growth and shape plants.

• Pests & Disease – Watch for aphids and powdery mildew, treating organically as needed.

With the proper care, autumn sage plants started from seed will thrive for years of stunning color.

Troubleshooting Common Autumn Sage Seed Issues

Even with the best practices, you may encounter an occasional issue when growing autumn sage from seed. Here are some common problems and solutions:

• Seeds not germinating – Ensure seeds are fresh and planted at correct depth. Soil may be too cold, hot or dry.

• Leggy seedlings – Seedlings grown in low light stretch out and become leggy. Provide brighter light conditions.

• Transplant shock – Seedlings may wilt after transplanting. Water gently and shade until established.

• Poor flowering – Insufficient sunlight, overcrowding, improper soil pH, or over-fertilization can limit blooms.

Adjusting conditions to determine the underlying issue can get your autumn sage back on track. Reach out to your local agricultural extension office if problems persist.
