COMMENTS

50-75 ppm N

Not necessary, remove premature flowers.

28-35 days after sticking

Do not over-mist.

50-75 ppm N

Pinch to remove flower buds.

35-42 days after sticking

Mist enough to rehydrate cuttings. Do not over-mist beyond Day 2 or 3. Do not stick cuttings too deep. Tall leaves can be trimmed if necessary.

50-75 ppm N

Not necessary, remove premature flowers.

28-35 days after sticking

Do not over-mist.

28-35 days after sticking

Stick cuttings the day of arrival, if possible.

50-75 ppm N

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

Stick cuttings the day of arrival, if possible.

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

50-75 ppm N

35-42 days after sticking

This Alyssum requires light mist and soil moisture. Can be rooted under a dome or tent. Do not over-mist.

50-75 ppm N

Recommended. Soft pinch. Lower nodes may become inactive.

100 ppm N starting at Day 7

Not necessary.

42-45 days after sticking

Quite easy to propagate. Do not over-mist. Remove from mist after 10 to 12 days. Allow media to dry slightly between irrigations to encourage root development.

50-75 ppm N starting day 7

Pinch once, prior to transplant.

35-42 days after sticking

Mist enough to rehydrate cuttings. Do not over-mist beyond Day 2 or 3. Arcadia is particularly sensitive to over-misting in propagation.

Balanced fertilizer 75-100 ppm

None

7-8 weeks

This is a tissue culture raised item. Please see our detailed tissue culture propagation guide at darwinperennials.com. This item is generally a Summer propagated item. Excessive heat can cause losses.

50-75 ppm N starting at Day 7

Remove buds/flowers in propagation.

42-49 days after sticking

Buddleia Chrysalis series is very free flowering. Budding in cuttings does not affect rooting. Watch media moisture levels. Excessive moisture will delay rooting.

50-75 ppm N

Pinch once in the liner stage.

35-42 days after sticking

Discontinue mist as quickly as possible once rooting occurs.

50-75 ppm N

Pinch once in the liner stage.

35-42 days after sticking

Discontinue mist as quickly as possible once rooting occurs.

50-75 ppm N starting day 7

Pinch once, prior to transplant.

35-42 days after sticking

Mist enough to rehydrate cuttings. Do not over-mist beyond Day 2 or 3. Saturated media will delay rooting. Remove from mist before completely rooted and dry media slightly to encourage rooting and better uniformity.

50-75 ppm N

Pinch once in the liner stage.

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.

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

Pinch once in the liner stage and once after transplant for best results.

50 ppm N starting at Day 7

Pinch once, prior to transplant.

35-42 days after sticking

Mist enough to rehydrate cuttings. Do not over-mist beyond Day 2 or 3. Do not oversaturate media.

Balanced fertilizer 75-100 ppm

None

42-49 days

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

50 ppm N starting at Day 7

Pinch to remove any flower buds.

42-49 days after sticking

Dianthus require very low mist settings to root. Over-misting will result in slow rooting and high losses in propagation.

50-75 ppm N

Not typical in propagation.

42-49 days after sticking

Digitalis root slowly with first roots showing 15 to 18 days after stick. However, it is best to discontinue mist prior to visible root, as they root more quickly when not over-misted and when media is allowed to dry slightly between waterings. Please refer to our complete Tissue Culture Echinacea guide at darwinperennials.com for detailed rooting information. Configure in liner stage can be beneficial.

50 ppm N starting at Day 7

Not necessary.

49-56 days after sticking

50 ppm N starting at Day 7

Not necessary.

49-56 days after sticking

Please refer to our complete Tissue Culture Echinacea guide at darwinperennials.com for detailed rooting information.

Begin feeding 50-75 ppm 10 days after sticking

Pinch 21-25 days after sticking.

42-49 days after sticking

Don’t oversaturate media. Low mist levels work best.
