Feed Like a Pro: When to Give and What to Give
Timing is everything. Let’s walk through the perfect feeding schedule to keep your clematis performing like a star.
1. Spring Wake-Up Call (Feb–April)
- As soon as you see new buds swelling, it’s go time.
- Use a balanced fertilizer (10-10-10 or 12-12-12).
- This gets roots, leaves, and stems growing strong.
2. Pre-Show Feed (May–June)
- Buds are forming—it’s almost bloom time.
- Switch to a low-nitrogen, high-phosphorus fertilizer (5-10-10 or 5-10-20).
- This helps maximize flower size and quantity.
3. Mid-Summer Encore (July–August)
- For reblooming types, another round of feeding fuels their second act.
- Same high-phosphorus formula, applied after the first flush of flowers fades.
4. Know When to Stop (Fall)
- Stop feeding by early fall.
- Late-season fertilizing pushes soft growth that’s vulnerable to frost.
- Let your clematis wind down naturally.
How to Apply Fertilizer Without Harming Your Clematis
Feeding isn’t just about tossing food in the dirt. Do it right to protect your plant and get the best results.
Use a “Feeding Ring”
- Picture a donut around your clematis—about 6–12 inches from the stem.
- Apply fertilizer in this ring to hit the active roots, not the base.
- Scratch it gently into the top soil layer.
Go Liquid or Granular
- Granular: Sprinkle and water well.
- Liquid: Dilute and apply in the evening or on cloudy days to avoid burning the leaves.
Always Water After Feeding
- Fertilizer needs water to soak into the root zone.
- Dry feeding can burn roots.
- Deep, slow watering is your best friend.
Going Organic: Natural Ways to Feed Your Clematis
Organic options are gentle, effective, and great for long-term soil health.
Top Organic Choices:
- Compost: Slow release, improves texture and moisture.
- Aged Manure: Nutrient-rich and perfect for containers or tired soil.
- Fish Emulsion or Seaweed Feed: Great for liquid feeding, especially in the growing season.
These build up your soil and provide steady, natural nourishment.
Understand Your Clematis Type: Feed Based on Pruning Group
Clematis aren’t all the same—each type has different needs and bloom times.
Group 1: Spring Bloomers
- Examples: C. montana, C. alpina
- Bloom on old wood.
- Feed after flowering to help prep for next year.
Group 2: Repeat Bloomers
- Examples: ‘Nelly Moser’, ‘The President’
- Bloom twice—on old and new wood.
- Need spring feeding, bud-time boost, and mid-season feeding.
Group 3: Summer/Fall Bloomers
- Examples: ‘Jackmanii’, ‘Sweet Autumn’
- Bloom on new growth.
- Feed heavily in spring and once again mid-season.
Know your group, and you’ll know when to feed.
Feeding Mistakes to Avoid
Even with the best intentions, you can trip up your clematis. Here’s how to avoid common pitfalls.
Don’t Overdo It
- Too much fertilizer—especially nitrogen—leads to leafy growth at the expense of flowers.
- Stick to the schedule and correct ratios.
Never Feed Late in the Season
- Feeding after summer can trigger tender growth that dies in frost.
- Always stop by early fall.
Avoid Dry Soil Feeding
- Applying fertilizer to dry soil can burn roots.
- Always check moisture first. If it’s dry, water first, then feed, then water again.
Support the Stars: Environment Matters Too
Your clematis needs more than food to perform—it needs the right setting.
Cool Roots, Sunny Tops
- Clematis like “cool feet.”
- Mulch with bark, straw, or compost to keep roots moist and shaded.
- Pair with shallow-rooted companions like lavender or catmint.
Provide Sturdy Support
- A vigorous clematis needs room to grow and something to climb.
- Use a trellis or arch that can handle heavy vines and loads of blooms.
Decoding Signals: When Your Clematis Is Telling You Something’s Wrong
Your plant may be sending distress signals. Learn to read them.
Yellow Leaves?
- Could be nitrogen deficiency—or overwatering.
- Check drainage and nutrient balance.
Lots of Leaves, No Flowers?
- Likely too much nitrogen.
- Switch to a bloom-boosting formula and assess sun exposure (aim for 6+ hours).
Stunted Growth?
- May be a pH issue.
- Clematis prefers slightly alkaline soil (6.5–7.0). Test and adjust with lime if needed.
