How to Grow the Fragrant Pistacia? A Detailed Guide to the Latest Cultivation Methods
The fragrant pistacia is a sun-loving tree, but it also tolerates slight shade. It likes warmth, requires deep soil, has strong sprouting ability, grows slowly and lives long, but its seedlings are not very cold-hardy and need protection in North China. The plant can withstand low temperatures of -10°C and prefers soil that is well-lit and not prone to waterlogging. It can be used for garden shrubs and cut branches. It grows wild in the dry-hot river valleys of central and northern Yunnan and southern Sichuan in China, at altitudes of 1300-2300 m.
Cultivation Methods for the Fragrant Pistacia
The fragrant pistacia is tolerant of drought and poor soil, has a well-developed root system and strong resistance. It is a pioneer tree species for afforestation and greening in dry-hot river valleys, and is also a major fuelwood and timber species there. The fragrant pistacia has a beautiful tree shape and a fresh fragrance, and has a variety of edible and medicinal functions, with broad development prospects. It needs protection in North China. The plant can withstand low temperatures of -10°C and prefers soil that is well-lit and not prone to waterlogging. It can be used for garden shrubs and cut branches.
The fragrant pistacia is quite sensitive to fertilizer, so seedlings should be fertilized as little as possible or not at all, to avoid fertilizer burn or excessive leggy growth caused by too much fertility. For cutting propagation, cuttings can be taken in both spring and autumn. Using plant non-test-tube rapid propagation technology, it can be done year-round: one leaf and one bud during the growing season, or a single branch segment during the dormant period. During the tree's dormant period, select 1-year-old healthy branches from a vigorous mother tree, cut them into propagation material 10-15 cm long and 0.3-1.0 cm thick, with the upper cut 1.0-1.5 cm from a bud and the lower cut 0.3-0.5 cm from a bud.
For the propagation substrate, it is best to choose river sand or perlite with good permeability. Before rapid propagation, the substrate can be sterilized with chemical agents such as potassium permanganate. Soak the base of the cut end of the propagation material in 50 ppm-100 ppm ABT rooting powder or indolebutyric acid solution. The soaking time is 12-24 h. For leaf-bearing one-leaf-one-bud propagation material, a treatment time of 1-2 hours is suitable; plant it shallowly in a smart seedling bed and start the system immediately. Branch-segment propagation material from dormant bases generally begins to root in about 30 d, while leaf-bearing propagation material generally begins to root in 15-20 days, with a survival rate of over 95%. This is currently the most effective method for rapid propagation of the fragrant pistacia.
Propagation Techniques for the Fragrant Pistacia
The fragrant pistacia is a sun-loving tree, but it also tolerates slight shade. It likes warmth and requires deep soil; it has strong sprouting ability and grows slowly, and needs protection in North China. The plant can withstand low temperatures of -10°C and prefers soil that is well-lit and not prone to waterlogging. It can be used for garden shrubs and cut branches.
Artificially cultivated fragrant pistacia seedlings are mainly grown from seed, but cutting propagation can also be used.
1. Seed propagation. The seed maturity period of the fragrant pistacia is very close to its shedding period. Once mature, the seeds fall off at the slightest wind or rain, making them hard to collect, or they are eaten by birds and animals. When the seeds begin to show signs of maturity, collect them from the tree in time. Fragrant pistacia seeds are wrapped in juicy flesh and are prone to contamination and mold, so the collected seeds must be processed immediately: pile the fruits to ferment, crush the fruit skin, wash them in water, remove the seeds and discard the debris, then dry them in the shade and store them in a ventilated, dry place.
2. Sowing season. Both spring and autumn are suitable, but autumn sowing generally has a higher germination rate than spring sowing. Before sowing, soak the carefully selected seeds in warm water at an initial temperature of about 20°C for 24 hours. Once the seeds swell after absorbing water, remove them and place them under warm, moist conditions to germinate. The usual seeding rate is 6 kg per mu.
3. Notes on seedling management. Fragrant pistacia seedlings have three fears: first, fear of waterlogging. The soil should be kept as dry and loose as possible, and generally not watered or watered as little as possible. Second, fear of shade. During the seedling stage, thin the seedlings in time to increase light penetration and ventilation. Third, fear of fertilizer damage.
4. Cutting propagation. Cuttings can be taken in both spring and autumn. During the tree's dormant period, select 1-year-old healthy branches from a vigorous mother tree and cut them into 10-15 cm long cuttings, with the upper cut 1-1.5 cm from a bud and the lower cut 0.3-0.5 cm from a bud. For the cutting substrate, it is best to choose a cutting medium with good permeability, moderate water-holding capacity, and a neutral or slightly acidic pH. Before cutting, the substrate must be sterilized. Soak the base of the cuttings in ABT rooting powder solution (use according to the instructions). The soaking time is 12-24 hours. Plant them in furrows, inserting the cuttings about 2/3 into the soil. After planting, cover with plastic film to increase air humidity. Manage carefully before rooting; rooting begins in about 45 days.
Potted Care Techniques for the Fragrant Pistacia
The young leaves of the fragrant pistacia are red and glossy, with a delicate color and form. It grows slowly, is easy to shape, has a faint fresh fragrance, and helps purify the air and repel mosquitoes and flies. People like to use it for indoor potted plants. Choosing ideal plant material is the basis for making a potted plant. Household potted plants mainly aim to show something small as if it were grand, creating a natural, fresh feeling of bringing wild mountains, waters and trees into the home. Therefore, materials must be carefully selected: choose small fragrant pistacia seedlings with curved or misshapen trunks, as well as old tree stumps with aged posture and beautiful, simple, antique tree shapes, and cultivate them in pots. Wild tree stumps dug from the mountains and fields are even better, but because this causes ecological damage, the author does not advocate it. After the plants to be cultivated are selected, carry out preliminary shaping and pruning according to the design concept, flexibly applying pruning methods such as thinning and heading back to remove crossing branches, overlapping branches, diseased and pest-infested branches, and leggy branches. Choose a purple-clay pot with good permeability as the potted container, fill the pot with soil and press it firm, and water to keep it moist. Because the fragrant pistacia likes light and sunshine, it should be placed in a ventilated, well-lit place such as a windowsill or balcony for cultivation. In daily care, flexibly apply shaping techniques such as coiling, tying, twisting and pressing, and shape it according to its natural tendency. After several years of care, an ideal potted plant can be cultivated.
