how often should i water my palm trees and how often should i bring them out for sunlight?

In summer, plants can be safely watered daily whereas in winter their needs are much less. The same parameters as for indoor plants apply - vigorous-growing plants will need more water more frequently than those growing slowly or not at all, plants will need watering more regularly in the summer than in the winter and plants growing in bright light will dry out more quickly than those in dim positions.
Other factors must also be considered such as the type of potting mix, the size of the pot and how full it is of roots and the prevailing temperature and humidity. The potting mixture must drain well but should also retain sufficient water for the plant's growth. Heavy soils that become soggy when watered are useless for plants as they only lead to rotting of the roots and retardation or death of the plant.
