Pruning
Pruning enhances the appearance of the Pistacia terebinthus L. plant and maintains its growth rate. Pruning should be done in the fall or early spring when the plant is dormant. Remove diseased, damaged, or dead branches with clean pruning shears to minimize the risk of disease. It's also advisable to remove any branches that cross each other as this can cause damage and reduce fruit production.
It's important to maintain the shape of the plant by trimming the top and sides to control its size. When pruning, ensure that the plant has enough space for air circulation as this reduces the risk of disease. Pruning also stimulates fruit production and ensures maximum yield.
Propagation of Pistacia terebinthus L.
Pistacia terebinthus L. is a deciduous shrub or small tree that is commonly known as turpentine tree. It is native to the eastern Mediterranean region and grows well in warm and dry climates. The plant can be propagated through various methods, as discussed below.
Seed Propagation
Pistacia terebinthus L. can be propagated through seeds that are collected from ripe fruits. The seeds need to be soaked in water for 24 hours or more to soften the hard coating. After soaking, seeds are washed and sown in a well-draining soil mix. The seeds need to be covered lightly with soil and kept in a warm and moist place. Germination usually takes 2-3 months, and seedlings need to be transplanted to individual pots once they have developed a few leaves.
Cuttings Propagation
Pistacia terebinthus L. can also be propagated through cuttings that are taken from healthy stems during the dormant season. The cuttings should be about 10-15 cm long and taken from the middle part of the stem. The lower leaves should be removed, and the cutting should be dipped in a rooting hormone. The cutting is then inserted into a well-draining soil mix and kept in a warm and moist place. Rooting usually takes 4-6 weeks, and once roots have developed, the cutting can be transplanted to a larger pot or planted directly into the ground.
Air Layering Propagation
Air layering is another propagation method that can be used for Pistacia terebinthus L. This method involves making a small cut in a healthy stem and wrapping it with a moist sphagnum moss or peat moss. The area covered with moss needs to be tied with plastic wrap to keep it moist. Once roots have developed, which usually takes 2-3 months, the stem can be cut below the rooted area and planted in a well-draining soil mix.
Propagation of Pistacia terebinthus L. can be done using seeds, cuttings, or air layering. Each method has its own advantages and disadvantages, but all can be successful in producing healthy and vigorous plants.
