No
Keep light levels as high as possible. No pinching needed. Do not allow plants to wilt. Ship this crop when one-third of the florets are open to reduce the risk of flower shattering during shipping.

No
Avoid planting plugs too deep. Maintain good fertilisation, especially at flower initiation. Monitor for aphids, botrytis, powdery mildew.
No
PGRs: 2 paclobutrazol sprays, the first approximately 3 weeks after transplant and the second approximately 2 weeks later. Possible third application may be necessary, subject to conditions. Delphinium are especially sensitive to powdery mildew; spray preventively if necessary. Ship and sell latest with flower spike one third open to decrease risk of petal shattering. See Cut Flower section for more details on cut flower production. Container production: PGR paclobutrazol 1 or 2 applications 20 ppm spray. 3-4 applications of PGRs are needed to produce in quart or gallon containers.
