If you’re captivated by these spectacular vines, visit us in-store to explore the many varieties we carry and find the best fit for your space!

Clematis Essentials

  • Ideal Conditions: Clematis thrive in sunny to partly sunny spots with well-drained soil. Roots should be kept cool, so consider planting them near low-growing shrubs for shade.
  • Hardiness: Most clematis varieties are hardy in Zone 6. For evergreen types like C. armandii and C. cirrhosa var. balearica, which are suited for Zones 7-8, extra winter protection is needed in our area.

When to Plant

  • Spring or Summer: Pinch growing tips for compact growth, and water regularly in summer.
  • Fall: This is an ideal planting time to encourage strong root development. Prune in spring, even if it means fewer blooms initially—this builds a healthier, bushier plant.

Where to Plant Clematis

  • On Fences or Trellises: If planting against a wall, use a removable trellis for easy maintenance. Wooden or metal frames offer both durability and style.
  • In Containers: Use a container at least 18” deep and wide with drainage holes. If space allows, add annuals or perennials around the base for visual interest. Choose containers that don’t conduct heat, like wood or ceramic.
  • Through Trees: Clematis vines grow lightly without damaging trees, though vigorous types like C. montana need larger trees for support. Position planting holes along the drip line for natural moisture.

How to Plant Clematis

  1. Prepare: Water the plant before removing it from the pot.
  2. Dig: Create an 18” deep and wide hole, adding 6” of compost or manure with a sprinkle of bone meal at the base.
  3. Position: Place the rootball so that 6” of the stem is below the soil line.
  4. Support: Attach the plant’s original stake to a long-term support structure to keep stems straight.
  5. Backfill & Water: Fill with soil mixed with bark mulch or peat moss for drainage. Water thoroughly.

Variety Suggestions

  • For Fragrance: C. armandii, ‘Fair Rosamund’, and ‘Sweet Summer Love’.
  • For Fences: C. montana varieties.
  • For Containers: ‘Bijou’ (up to 3’), and other compact varieties.
  • For Shadier Spots: C. alpina, C. macroptela, and Jackmanii types.

Clematis Feeding Tips

  • Spring to Early Summer: Feed with 10-15-19 or 14-14-14 as new shoots emerge, continuing until buds form.
  • Mid-August: Stop all feeding to allow the plant to prepare for dormancy.

Clematis Pruning Simplified

Pruning depends on the clematis group, which is noted on the plant’s information tag or based on bloom timing. Pruning helps improve shape, growth, and flowering.

  • Group A: Flowers on old wood. Prune after flowering in May/June to remove weak or dead stems.
  • Group B1 & B2: Flowers on old and new growth. Light pruning in late February or March. For neglected vines, cut back severely for rejuvenation.
  • Group C: Flowers only on new growth. Prune in February/March to two strong buds close to ground level for fuller growth and blooms from summer to fall.

Clematis as Cut Flowers

Clematis make beautiful, long-lasting cut flowers, lasting 5-10 days indoors. Pick them as buds are opening, and enjoy fluffy seed heads as unique seasonal decorations.
