Fertility:
Geum will grow well under low to moderate fertility levels. Using water soluble fertilizers, apply 150-200 ppm of nitrogen as needed, or use a constant liquid feed program at rates of 75-100 ppm nitrogen. If using controlled release fertilization, apply as a top dressing on the soil surface using the moderate labeled rate. This can also be incorporated into the potting media at a rate equivalent to 0.9 to 1.1 pounds of elemental nitrogen per yard of media.
Vernalization:
Cold beneficial. Flowers earlier and more profusely following a cold treatment.
Pests & Diseases:
Aphids, black vine weevil, leafminers and spider mites can sometimes be problematic.

Moisture:
Keep uniformly moist, but not consistently wet.

Liner soil line should be placed even with container soil line.
PGRs/Pinching:
For control of flower height use Bonzi at 30 ppm or Sumagic at 5 ppm as stems begin to emerge from the foliage. Several applications may be needed at 7-10 day intervals.
Lighting:
Day neutral, will flower under any day length.
