Growing Tips & Seasonal Care for Long-Blooming Perennials
Now that you’ve got your list of summer superstars, let’s make sure they bloom at their best all season long. With a few smart techniques, your perennials will thrive from late spring through fall — and come back even stronger next year.
☀️ 1. Plant in the Right Location
Most long-blooming perennials love full sun — aim for 6 to 8 hours of direct light daily. For plants like phlox or bleeding heart that prefer a bit of shade, choose spots with filtered sunlight or partial shade during the hottest part of the day.
Pro Tip: Observe your garden throughout the day before planting to understand sun patterns.
🌱 2. Prepare the Soil
Healthy soil = happy blooms. Here’s how to get it right:
- Mix in compost or aged manure to enrich the soil.
- Ensure good drainage, especially for drought-tolerant varieties like lavender, yarrow, and Russian sage.
- Test soil pH if possible — most perennials prefer neutral to slightly acidic conditions.
💧 3. Water Wisely
- Water deeply but infrequently to encourage deep root growth.
- Avoid overhead watering to reduce fungal risk — water at the base.
- Mulch around plants to retain moisture and suppress weeds.
Drought-tolerant doesn’t mean no water — especially in the first growing season.
✂️ 4. Deadhead Regularly
Removing spent blooms encourages many perennials to keep flowering.
- Coreopsis, coneflowers, and salvia especially benefit from deadheading.
- For daylilies, snap off spent blooms daily if possible for a tidier look and stronger rebloom.
💪 5. Fertilize with Care
- Use a balanced, slow-release fertilizer in early spring.
- Avoid high-nitrogen fertilizers — they promote leafy growth at the expense of flowers.
- Compost tea or organic bloom boosters work well mid-season.
🌼 6. Divide and Conquer
Every 2–3 years, divide perennials like phlox, black-eyed Susan, and daylilies to:
- Rejuvenate older plants
- Prevent overcrowding
- Expand your garden for free!
Do this in early spring or after the main bloom season ends.
🐝 Bonus Tip: Go Pollinator-Friendly
Many of these perennials — especially lavender, coneflowers, verbena, and salvia — attract bees, butterflies, and hummingbirds. Plant them in clusters for maximum visual and ecological impact.
By giving your perennials just a little TLC throughout the season, you’ll be rewarded with waves of flowers that just keep coming.
Frequently Asked Questions (FAQ)
🌸 How do I get my perennials to bloom all summer long?
The key is consistency:
- Deadhead regularly to encourage new blooms.
- Water deeply during dry spells.
- Use organic mulch and compost to keep roots happy.
- Apply a bloom-boosting fertilizer mid-season if needed.
🌼 Do I have to replant these every year?
Nope! That’s the beauty of perennials. Once established, they come back year after year, often with even more blooms. Just be sure to divide them every few years to keep them healthy and vigorous.
☀️ Can I grow these in containers?
Yes — especially compact varieties like catmint, lavender, coreopsis, and salvia. Use large pots with good drainage and water more frequently, as containers dry out faster.
🌱 When is the best time to plant summer-blooming perennials?
Spring is ideal, but early fall works too in most climates. This gives roots time to establish before the next bloom season. For instant color, you can also plant nursery-grown perennials in early summer.
🐝 Which of these perennials are best for pollinators?
All of the following are bee, butterfly, and hummingbird favorites:
- Coneflower
- Lavender
- Verbena
- Salvia
- Black-eyed Susan

Mix them together for a wildlife-friendly pollinator paradise!
