When to Plant:
Late summer to early fall
Late winter to late spring
Finish:
10 - 12 weeks
Grower Tips:
Varieties that have attractive flowers should be planted in late summer for the best spring floral display. If planted in spring, flowers should be removed until plants have reached the desired size.
Growing Temperature:
65-68° F
Holding Temperature:
50-60° F
Soil PH:
5.5- 6.2
EC (What is EC?):
2.0-3.0 pour through method
Fertility:
Heucherellas are light to moderate feeders requiring nitrate levels of 50-100 ppm under a constant liquid fertilizer program. Alternatively, a controlled release fertilizer at a rate equivalent to one pound of nitrogen per yard of growing media may be used.
Vernalization:
Not required
Pests & Diseases:
Mealybugs, root weevils, fungus gnat larvae (in greenhouse), foliar nematode, four lined plant bug.
Botrytis blight, leaf spots (Colletotrichum and others), powder mildews, anthracnose, bacterial leaf spot (Pseudomonas, Xanthomonas), stem rot, leaf and stem smut, leafy gall (Corynebacterium), root rots, rust, sunburn(purple foliage cultivars).
Potting & Timing:
Root Trimming: Trim if necessary.
Cooler temperatures will increase the time to flower but will improve the overall quality.
Moisture:
For potting soil use commercial planting media. Heucherellas prefer average moisture levels. They do not tolerate overly wet or overly dry conditions. Under high light intensities, marginal leaf burn may occur if the plants become water-stressed. Do not allow to dry out between waterings.
Planting Level:
At crown level.
PGRs/Pinching:
Remove flowers until plant reaches desired size. No PGRs are nessesary if plants are grown under proper conditions and spacing.
Lighting:
Provide 30 - 50% shade in the north and 50 - 70% shade in the south.
