Cultural information for alstroemeria
Planting Depth:
Clumps should be planted no deeper than 1-2 inches below the soil surface and spaced about 3' apart; this is not a critical distance.
Soil:
a light, well-aerated mix. Rhizomes are susceptible to fungal rot if they sit in soggy soil. The soil should be kept moist but not soaked until sprouts appear. Sprouts should appear in 2 weeks, depending on temperature of soil. Roots are usually well-formed about a month after planting and continue to expand into the parent soil for a year. As the rhizomes grow and branch, the original pieces die (no need to remove).
Irrigation. Water the plants as frequently as you would an aster, chrysanthemum or tomato. They benefit from watering to replace water lost, but the soil must be well-drained and porous.
Sun:
Full sun or filtered sun, as under a birch tree, is satisfactory, and morning sun only works, too. Mid-day and afternoon shade in July and August encourages prolonged flowering and deeper pigmentation. Protect clumps from afternoon sun in warm climates
Fertilization:
This is not critical for success. We find that alstroemeria is not a heavy feeder.
Note: In cold climates, Zone 6 and below, make sure that you provide winter protection to keep the ground from freezing. If using large containers you will have to put them indoors before the first sub-28 F freeze and keep them dry for the winter.
