Sunflowers are one of the most beloved flowers with their big, bright yellow blooms that put smiles on faces. Sunflowers cultivated annually should come from seed, not cuttings. However, perennial sunflowers can be grown from cuttings. Though different kinds call for different techniques, propagating perennial sunflowers from cuttings is more difficult than from seed.
Why Replant Sunflowers
There are several great reasons to give replanting cut sunflowers a try:
- Extend the life of bouquet flowers instead of letting them go to waste,
- Get free new sunflower plants for your garden rather than buying starters
- Enjoy beautiful, robust blooms from mature cut stems versus small seedling blooms.
- Grow your own sunflowers after receiving them as a gift or from the florist.
- Multiply your sunflower crop from just a few purchased stems.
- Have fun experimenting and engaging kids in planting projects.
Replanting cut stems is an eco-friendly way to reduce waste and take your sunflower enjoyment to the next level!
How to Replant Fresh Cut Sunflower Stems
Trying to regrow a sunflower right from a fresh cut bouquet is challenging but definitely possible. Here are some tips:
- Start with fresh stems that were cut rather than wilted flowers. Look for thick, sturdy stems without split ends or damage.
- Remove all foliage from the lower half of the stem so you have a clean segment for planting.
- Slice the stem at an angle before putting in water to expose more surface area for water intake.
- Place in a vase with fresh water and floral preservative. Change the water daily.
- After a week, you should see little white bumps forming where new roots will emerge.
- Plant the stem in potting soil keeping it upright and stable. Bury at least 2 inches of the lower stem in the soil.
- Place in a sunny spot, keep moist but not soaked, and wait patiently for sprouts!
With proper care, the stem should form roots and sprout new leaves in 2-6 weeks. It can take 8-12 weeks before flowers bloom. The replanted stems have the best success rate if started in water within 2 days of being cut.
How to Replant Dry Sunflower Stems
Dry sunflower stems or heads purchased from a craft store, nursery, or dried bouquet can also be planted. Follow these guidelines:
- Inspect the base of the stem and look for a callus or knob showing it was cut, not broken off. Avoid thin, brittle stems.
- Soak the dry stem in water for 24 hours before planting to rehydrate it.
- Fill a small pot with soil and make a hole deep enough to bury 2 inches of the stem.
- Place the stem in the hole and fill with soil, keeping it upright. The buried portion should have some cracks or rough texture for new roots to emerge.
- Water well and let drain. Keep moist but not saturated as it sprouts.
- Be patient – it may take 4-6 weeks to see signs of new growth. Don’t give up too soon!
The rehydration step is vital for dry stems to absorb enough water and regain the cellular turgidity needed for new growth.
