COMMENTS

50-100 ppm N

Recommended.

42-49 days after sticking

50 ppm N starting at Day 7

Yes, pinch once in propagation around Day 21.

42-49 days after sticking

Eupatorium are quite easy to root. Use a basal hormone tip to ensure rooting uniformity.

Yes, 7 days before transplanting.

35-42 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

75-100 ppm N when roots become visible; increase to 150-200 ppm N as roots develop

35-42 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50-75 ppm N when roots become visible

Recommended after roots are established. Leave 4-5 active internodes.

50-75 ppm N

Pinch once in the liner stage.

42-49 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

Feed at 100 ppm N after 9 days

Pinch once shoots elongate for best branching.

35-42 days after sticking

Typically remove from propagation area after two weeks. Don't keep rooting media excessively wet. Use long-day lighting when propagating when day length is less than 12 hours. Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation. Long day obligate plant. Must provide long days in propagation.

42-49 days after sticking

50 ppm N starting at Day 7

Recommended after roots are established. Leave 4-5 active internodes.

35-42 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation. Long day obligate plant. Must provide long days in propagation.

50-75 ppm N when roots become visible

Recommended after roots are established. Leave 4-5 active internodes.

50-75 ppm N after 14 days Not necessary.

8-10 weeks after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C).

50 ppm N starting at Day 7

Not necessary.

56-63 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Review our Heuchera Tissue Culture guide at darwinperennials.com/Culture/ProductionGuides. Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation. Cuttings typically arrive with flowers already induced due to cool night temperatures in Colombia. Non-induced cuttings require 6 weeks of night temperatures below 55°F (13°C) to flower.

28-35 days after sticking

50-75 ppm N when roots become visible

Recommended after roots are established. Leave active internodes.

42-49 days after sticking

Iberis benefit from a basal IBA dip prior to sticking. Do not over-mist or high losses can occur.

100 ppm N starting at Day 10

Yes, pinch after 4 weeks. Can be double pinched in the liner stage for even greater branching.

50 ppm N when roots become visible

Not necessary.

12 weeks after sticking

May be transplanted sooner than 12 weeks, but bulking in the liner is more efficient than in the finished container.

50-75 ppm N

Recommended.

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50-75 ppm N

Recommended.

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50-75 ppm N

Recommended after roots are established. Leave 4-5 active internodes. Recommended after roots are established. Leave 4-5 active internodes. Recommended after roots are established. Leave 4-5 active internodes. 2 pinches in liner is good. Can pinch a third time for higher flower count.

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50 ppm N starting at Day 7

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50 ppm N starting at Day 7

50 ppm N starting at Day 7

Pinch 21 days after sticking.

35-42 days after sticking

For fastest, most reliable rooting, do not oversaturate rooting media.

50-75 ppm N

Not typically necessary.

42-56 days after sticking

Use low mist settings; do not oversaturate rooting media. Root zone temperatures of 70°F (21°C). Remove flowers in propagation.

50 ppm N starting at Day 7

Pinch 21 days after sticking.
