Okay, so I already have an arum maculatum tuber in the ground. It comes up with a leaf every year in winter, but so far, has never flowered.
Yesterday, I bought six tubers at the garden center - 2 to a package. They are in solid green plastic bags in peat moss. I couldn't see them well, so I just went by touch to make sure they were a reasonable size compared to some of the other packaged tubers and firm to touch.
The brand name is Van Bloom. This time I want to make sure I do this right, not that I did it wrong. Maybe it takes a few years to reach blooming size? These tubers feel like they are about 2" tubers, maybe about 1" in diameter - kind of elongated.
I know that arums like well-drained soil. I am assuming they like moist soil? Do they like rich soil? Would equal parts of compost, peat, and garden soil, with some pine bark thrown in, and a little chicken manure be okay?
Do they like to be fertilized, and if so, with what - like kelp, high phosphorus, or what?
Is it best to plant them in the ground now, or wait until after last frost? Or, after last frost, plant them in pots for the first year? I think they would do fine in pots outdoors over winter here, since I am in zone 7.
I see little about planting these well. I know they are native, or that they perennialize easily in some areas, but mine has been very slow to take off. I did notice yesterday that the single leaf it has sent up, which is a fairly large leaf for this plant, is preparing to send up another leaf, or what looks like it will be another leaf.
Thank you for your responses.
