EC (What is EC?):

2.0-3.0 using the pour-through method

Fertility:

Feed 100-150 ppm N with every watering.

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:

Provide at least 8 weeks of temperatures below 40° F.

Pests & Diseases:

Generally pest and disease free, watch for aphids and botrytis.

Potting & Timing:

Plant in a well-drained soilless media.

Moisture:

Provide moderate moisture levels. Plants are relatively drought tolerant once established.

Planting Level:

Liners even with the soil line, bare root with eyes slightly below the soil line.

PGRs/Pinching:

PGR not typically needed if grown under ideal conditions, Sumagic (Uniconazole) at 5-10 ppm may be used for toning.

Growth regulator rates are suggestions but may vary due to time of year, region and water quality. Trialing is always recommended before applying to an entire crop.

Lighting:

Higher light is preferable in production to minimize stretching. Spigelia will grow well in either sun or partial shade in the landscape in Michigan, although it is a bit quicker to bulk up in full sun.

Other Comments:

Spigelia do best when grown cooler, and cooler temperatures (55-60F) will result in less stretch and also help the root system to maintain equal growth with the top. They can be grown warmer, up to 70F, but will likely need additional growth regulation to help minimize stretch at warmer temperatures.
