How To Water Mirlitons

Guttation is the exudation of drops of xylem sap from the tips of mirliton leaves (it is not dew, which condenses from the atmosphere). When the plant has more than enough water available to the roots, it will push water out through leaf tips early in the morning. This means the plant has sufficient water. Heavy guttation every day can be a sign of too much water and the possibility of waterlogging. The absence of guttation for several days and wilting of leaves during the day can be a sign of insufficient water. By monitoring guttation and leaf wilting, you can find a good balance for a watering schedule. Checking the soil using the "finger test" or a smooth dowel can be combined to confirm available water levels. See more on guttation at http://en.wikipedia.org/wiki/Guttation
Morning guttation. It is easy to distinguish from dew because the water droplets will start at the top edge of the leaf and appear at first as droplets emerging from the glands.
Guttation on bottom edge.
Light guttation on the edges.
Guttation along edge.
Guttation driplets on leaf edges
Guttation on leaf edges, and dew on the face of the leaf.
Guttation on edges, dew in the middle.
Close-up of guttation coming from the brown gland tips on the leaf edges. This is light guttation and indicates the plant has about the right amount of water available and will probably go a few days displaying no guttation. That would be a good time to observe the leaves in mid-afternoon for wilting. Wilting can be a sign of lack of water, especially if there is no sign of morning guttation. Too much water can also cause leaf wilt during the day, but if you don't detect morning guttation, the problem is probably not excess watering
Solitary droplet. Very little guttation.
Light morning guttation in the form of droplets.
