Baptisia grows best in full sun, though it tolerates light shade. If grown in too much shade, plants may require staking. Baptisia is easily grown in poor to average soil that is well-drained. Once established, it is moderately drought tolerant because of its tough, deep taproot. This perennial native may take a couple of seasons to become established, but is very long-lived once mature. Avoid disturbing established clumps.

Homeowner Tip: Though Baptisia is a large perennial, it can be grown in smaller gardens if maintained a bit differently. In early spring, set out a peony ring (circular wire stake) for the Baptisia to grow through. This will help it to grow more upright and take up less horizontal space. After the plant is finished blooming, prune it lightly throughout the season to keep its size in check. Seed pods may not develop in fall due to the pruning, but the flowers and foliage will be beautiful.

Holding Temperature:

40-50° F

EC (What is EC?):

2.0-3.0 pour through method

Fertility:

Requires 100-150 ppm fertilizer for optimal growth. For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.

Vernalization:

8-10 weeks if planted from plugs during early summer.

Pests & Diseases:

Leaf spots, powdery mildew (Erysiphe and Microshaera), rust (Puccinia), root rots.

Potting & Timing:

Generously graded bare root plants should bloom the first year.
Plugs can be planted in late spring to early summer and sold the following spring. This option yields the greatest number of stems per pot.
Forcing plants under cool temperatures will help control height and will intensify flower color but may increase crop time.
Baptisia will flower in 8-10 weeks at 50-60° F.

Moisture:

Water well after planting and increase watering as the foliage emerges. Dry to moderate moisture levels.

Planting Level:

Plant crown just below soil surface for bare root. Plant plugs 1/2" below the soil surface.

PGRs/Pinching:

Drench with Uniconazole (Sumagic/Concise) at 1 ppm once plants reach 6 inches in height.
Toning sprays at 5 ppm can be applied later if more control is needed. Best height control is growing Baptisia under cooler temperatures.

Lighting:

Provide high light levels. Grow under clear poly or outdoors.
