With the right production schedule, poinsettias can be grown in almost any size container, even as small as 2.5 in. pots. Needless to say, low-vigor cultivars work best. Irrigation can be difficult for miniature poinsettias as they dry out quickly and plants may need to be irrigated several times a day. Ebb-and-flow irrigation works the best. Capillary mats work well but can encourage the stretch. If using capillary mats, allow plants to dry occasionally to reduce stretch. If using sub-irrigation be sure to leach frequently as EC can increase rapidly in the small substrate volumes. Apply approximately 200 ppm N, but not with every irrigation. The following schedule (courtesy of Paul Ecke Poinsettia) can be used.
| Dates | Activity | Comments |
|---|---|---|
| Aug. 22-28 | Stick un-rooted cuttings | Use small cuttings (1.5 in.) |
| Sept. 3-Oct. 25 | Begin weekly height control | Cycocel sprays (1,000 ppm) weekly or as needed |
| Sept. 12-20 | Pinch | Leave 3-5 nodes |
| Sept. 20-25 | Begin SD | Early flowering cultivars may initiate flowers early |
| Oct. 3-11 | Remove old leaves | Remove only large leaves to allow smaller leaves to show |
| Nov. 1-12 | Late-season height control | Paclobutrazol drench (0.25 ppm), if needed |
| Nov. 15-25 | Market |
