Growth Stages

1

Establishment

First 4-6 weeks

Young vine with basic leaf structure; minimal growth above ground while roots establish

Water regularly to establish root system. Provide sturdy support structure. Protect from wind. Avoid heavy pruning first year.

2

Vegetative Growth

Spring through early summer, 8-10 weeks

Rapid stem elongation with dense foliage production; vines climb and twine around support

Train vines onto support structure. Water consistently. Apply balanced fertilizer monthly. Remove any dead or damaged stems.

3

Flowering (First Flush)

June through August, 6-8 weeks

Large double or semi-double flowers (4-6 inches) appear on new growth in deep red-purple with prominent darker veins

Deadhead spent flowers to encourage continuous blooming. Water during dry spells. Provide afternoon shade in hot climates. Apply phosphorus-rich fertilizer.

4

Reflowering

Late August through September, 4-6 weeks

Second flush of blooms appears on new growth; flowers may be slightly smaller than first flush but still abundant

Continue deadheading. Maintain consistent watering. Light fertilizer application. Prepare plant for dormancy as temperatures cool.

5

Dormancy

October through March, 5-6 months

Foliage yellows and drops; vines become bare woody stems; plant enters winter rest period

Stop fertilizing. Reduce watering but maintain minimal moisture. Prune lightly in late winter (Group 2 pruning). Mulch heavily for frost protection.
