I think the most common questions in this part of the forum usually center around resumption of watering within this group during the spring. Here is my answer: I'll probably wait a few more weeks to begin watering this plants. Notice the shriveled bulbs and roots that are already long. This group is well adapted to such things and are better off not being watered so that a new, extensive root system is well established for the growing year. For whatever reason, water on short roots stops all or most root growth for the year.

And the following picture shows a small statured species (as opposed to the large ones in previous pics) that is also still not getting watered, despite the spike its putting out right now. This is Catasetum denticulatum with its first spike.
