60-65° F

Holding Temperature:

50-60° F

Soil PH:

5.8-6.5

EC (What is EC?):

1.5-2.5 pour through method

Fertility:

Feed 100-150 ppm N at each watering.

Vernalization:

Provide 8 weeks of temperatures below 40° F.

Pests & Diseases:

Aphids, thrip, and spider mites are the main pests of Penstemon.
Crown and root rots can be problematic if grown under improper conditions. A fungicide drench is recommended after planting bare root.

Potting & Timing:

Plant small plugs in late summer for bulking purposes.
Bare root is best for quick turn spring crops or larger containers such as 2-3 gallon.

Moisture:

Moderate moisture

Planting Level:

Plant crown even with soil line.

PGRs/Pinching:

Daminozide (B-Nine/Dazide) at 2500 ppm or paclobutrazole (Bonzi) at 5-10 ppm are effective at controlling elongation.

Lighting:

High light levels produce the best looking plants. Direct sunlight outdoors is best for achieving the proper foliage color. Flowers under natural daylengths.
