The Pistacia grows erect, developing a short stem with a small crown, usually roundish. These plants are shrubs. This plant in the summer assumes a green colouring; it is medium in size and can reach 90 cm high. It doesn't keep its leaves in the winter.
Letís avoid watering the the Pistacia excessively, always leaving the soil dry for a few days between one watering and the other, therefore letís irrigate the substratum deeply every 10-11 days with 2-3 glasses of water . These plants are located in vases; to avoid them from enduring long periods of drought we suggest to check the moisture of the substratum in the vase periodically.
