PINCHING

TRANSPLANTING

COMMENTS

50 ppm N starting at Day 7

One or two pinches prior to transplant.

42-49 days after sticking

Lysimachia should root quickly. Watch for oversaturated media.

50-75 ppm N

Recommended.

28-35 days after sticking

Do not oversaturate rooting media. Use long-day lighting when day length is less than 12 hours to keep plants actively growing.

50-75 ppm N

Pinch once, prior to transplant.

35-42 days after sticking

Do not oversaturate rooting media. Use long-day lighting when day length is less than 12 hours to keep plants actively growing.

50-75 ppm N

Recommended.

35-42 days after sticking

Roots quickly. Plan to pinch in liner tray.

50-75 ppm N

Recommended.

35-42 days after sticking

Roots quickly. Plan to pinch in liner tray.

50-75 ppm N

Yes, pinch 14-18 days after stick.

35-42 days after sticking

Nepeta root easily. Over-misting causes slow rooting and leaf spot diseases.

50 ppm N when roots become visible

Benefits from one pinch prior to transplant.

42-45 days after sticking

Don't oversaturate the media. Remove from mist once root initials are visible.

50-75 ppm N

Recommended.

35-42 days after sticking

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

50-75 ppm N

Recommended.

35-42 days after sticking

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

50-75 ppm N after 10 days

Recommended.

35-42 days after sticking

Do not oversaturate rooting media. Allow media to dry moderately starting 10 days after sticking to encourage root development.

50-75 ppm N after 10 days

Recommended.

35-42 days after sticking

Do not oversaturate rooting media. Allow media to dry moderately starting 10 days after sticking to encourage root development.

42-49 days after sticking

Plants grow more actively under long days. Use 13-hour extended day lighting for Winter propagation.

75-100 ppm N starting at Day 7

Yes, while young plants are soft and actively growing. Allow at least two leaf internodes at each pinch. Yes, while young plants are soft and actively growing. Allow at least two leaf internodes at each pinch. Yes, while young plants are soft and actively growing. Allow two internodes at each pinch.

42-49 days after sticking

Plants grow more actively under long days. Use 13-hour extended day lighting for Winter propagation.

75-100 ppm N starting at Day 7

42-49 days after sticking

Plants grow more actively under long days. Use 13-hour extended day lighting for Winter propagation.

75-100 ppm N starting at Day 7

None

7-8 weeks after sticking

This is a tissue culture raised item. Please see our detailed tissue culture propagation guide at darwinperennials.com.

Balanced fertilizer 50-75 ppm once rooted to the bottom

35-42 days after sticking

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

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.

35-42 days after sticking

Begin fertilizing 7 days after stick.

50-75 ppm N

35-42 days after sticking

Roots quickly. Plan to pinch in liner tray.

50-75 ppm N

50-75 ppm N at Day 7

A soft pinch will increase branching.

35-42 days after sticking

Discontinue mist as quickly as possible and only mist to avoid leaf wilt. Begin feeding 7 days after sticking with 50-75 ppm N.

50-75 ppm N at Day 7

A soft pinch will increase branching.

35-42 days after sticking

Discontinue mist as quickly as possible and only mist to avoid leaf wilt. Begin feeding 7 days after sticking with 50-75 ppm N.

50-75 ppm N at Day 7

A soft pinch will increase branching.

35-42 days after sticking

Over-misting and saturated propagation media will dramatically delay rooting and increase rooting losses. Discontinue mist as quickly as possible and only mist to avoid leaf wilt.
