Q.Pygmy Date Palm
How much water is required for a pygmy date palm (and is this best accomplished through a drip system?)? Does the pygmy date palm require significantly less water than a Chinese Flame tree? How much less?
Typically once a week watering is sufficient for an established Pygmy Date Palm.
