General Plant Information
Persian Sour Plum ‘Tabriz’ Tree – Goje Sabz
In Iran, the arrival of Spring is celebrated extensively as the Persian new year coincides with the Spring Equinox. As Spring progresses, blossoms gradually turn into fruit. One of the highlights of Spring fruit is the arrival of Persian Plums from Tabriz. This variety of plums is picked when they are still green. They are indeed extremely popular amongst Iranian children and adults alike. The perfect Persian Plum is green, crunchy when bitten into, yet juicy with a very pleasant tart flavor. It’s pretty much impossible to not get hooked after the first one.
This variety of plum is well known in the Middle East. The tree itself is relatively small and thrives in locations with cooler Winter temperatures while the tree is dormant. The fruit at the time of harvest is green, round and small. If not harvested during its green stage, the plums eventually turn into a deep golden color. At this point, these small plums turn soft, juicy, and sweet. The variety of Persian Plum trees sold at Paradise Nursery is from the northern Iranian city of Tabriz.
Uses and In Cuisine
The Persian Plum from Tabriz is delicious when eaten raw with a sprinkle of salt. Additionally, Persian Plums are also used in Persian cuisine to enhance some dishes’ flavor with their pleasant tart taste. A popular dish that tastes best when cooked with Sour Plums is Koofteh Tabrizi, a large round stuffed meat loaf simmered in beef broth with a handful of green plums added to it. Additionally, cooking the green plums with cubes of lamb, parsley, and mint makes for a delicious Khoresh, Persian stew, which is then served over Persian rice.
Well known in Middle Eastern cultures, the Persian Plum is a very popular Iranian fruit tree that can be picked while green. The taste is tart and it is well paired when eaten raw with a sprinkle of salt. The fruit is small and round with a crunchy texture and juicy delicious flavor. The fruit can be left on the tree to fully ripen into small, soft, sweet and juicy deep golden color plums. Iranian green plums are relatively small deciduous trees and thrive in areas with cooler temperatures during Winter dormancy months. The variety of Sour Plum tree sold at Paradise Nursery is from the city of Tabriz.
In the home orchard, plant trees about 10 feet apart, and trim them to stay between 8 – 15 feet tall. In a commercial farm, trees are spaced 15 feet apart with 20 feet rows are machinery. These trees are grow to 25 feet tall. Trees can become almost 40 feet tall in nature.
Standard and Semi-Dwarf Form: Our trees are grown in Standard and Semi-Dwarf forms. A Standard tree grows tall because the tip continues to grow. The tip of a Semi-Dwarf tree has been cut about 2 feet from the ground, therefore the tree has a shorter branching structure for easy picking.

Plant Care Information
How To Water - Frequency and Duration to Irrigate
Newly planted trees should be watered regularly to establish well. The frequency of irrigation and quantity of water mainly depends on the season of the year, soil type, and size/age of the tree.
Frequency to water
Discontinue watering in the Winter while the tree is dormant.
Begin to water weekly as the tree breaks bud and leafs out in the Spring.
Increase the frequency of water to twice per week in the Spring.
Water 2-3 times per week during the hot Summer months.
Reduce irrigation frequency to 1-2 times per week in the Fall.
Stop watering your tree in the Winter while it is dormant.
You may need to water sandy soils more frequently but less quantity because of sand’s lower water holding capacity.
Water Duration – Quantity of water
Drip System – 30- 60 minutes
Sprinkler – 15 – 25 minutes
PVC Bubbler – 5 – 7 minutes
Hose – Flood the trees watering well until the soil surrounding the tree’s roots reaches field capacity.
Fertilizer and Plant Nutrition
Fruit trees and edible plants need nutrients to grow. This is called fertilizer and it comes in different forms. Use organic manure, bone meal, blood meal, and humus based fertilizers. Apply fertilizers like manure along with a bone meal, humus based phosphorus fertilizer (1-2-2) NPK ratio in the late Winter, right before spring growth. Reapply with organic high nitrogen (2-1-1) or fertilizers with a 1-1-1 NPK as directed by the label during the Spring and Summer growing season. Do not fertilize in the Fall, new growth at this time will be thin, lanky, and weak.
Winter Pruning and Summer Thinning
Prune fruit trees in the Winter to maintain size and shape to prepare for Spring growth. Thin the tree in the Summer, and remove excess fruits. Remove any dry twigs and branches. Cut off any new growth below the graft or very low in the tree, this will direct the plant’s energy to its main branches. Thin your trees during the Spring and Summer seasons to ensure the plant’s energy is directed as desired. If the plant provides an overly large quantity of fruits for that branch, reduce the quantity of fruit so that what remains grows larger. This will also prevent broken limbs. Harvest ripe fruit to prevent undesired pests.
Harvesting and Pest Management
The basics of integrated pest management is cleanliness and the use of a combination of methods. This means we use an organic pesticide when the pest population reaches a threshold that requires action. Horticultural oils such as Neem oil is an organic pesticide that controls tiny, soft bodied insects. Use organic Bordeaux and Liqui-cop to manage fungus causing diseases such as powdery mildew, rust, and leaf-curls.
Keep a clean environment, free of weeds and dropped fruit that host insects or attract animals. Harvest when fruit reaches size and store indoors. Use repellants and bird netting to protect your harvest from other animals.
Limited Guarantee and Returns
The two factors that determine if a deciduous fruit trees will grow well and produce fruit in a certain area are the Chill Hour Requirement and the Cold Hardiness. “Chill hours” are the amount of cold a deciduous fruit tree need to produce fruit. This is measured in the number of hours below 45 degrees Fahrenheit a plant must experience during its winter dormancy. Paradise Nursery only grows Low Chill fruit trees that meet the chill requirements of all areas of the United States.
The second factor is Cold Hardiness. Cold Hardiness refers to the minimum temperature a plant can tolerate. The USDA’s Cold Hardiness Zones indicate the average minimum winter temperatures of areas. Based on the shipping zipcode, our website will only allow you to add plants to your cart that grow within your USDA Hardiness Zone, and tolerate your climate.
Pollination & Propagation
(Grafting/Cutting) Most of Paradise Nursery’s edible plants are self-fruitful. Self-pollinating trees do not require an additional tree to produce fruit. For your convenience, we have indicated which trees require a pollinator, and their associated pollinators. Only the sweet cherries, avocados, and some plums require a pollinator. All of our other propagated edible plants do not require a pollinator. All of our edible plants are either grown from cuttings, budded, or grafted. This way, we can ensure that our plants are high quality and fruit immediately. Plants will generally begin fruiting within a year of planting.
