How Long Does a Walnut Tree Take to Grow? The duration for a walnut tree to grow depends on various factors. Walnut trees are slow-growing trees that take several years to reach maturity. The exact time it takes for a walnut tree to grow depends on several factors, including the variety of walnut trees, growing conditions, and care.
Generally, it takes 7-10 years for a walnut tree to begin producing nuts and up to 20 years to reach full maturity. Based on this, you must be patient when planting a walnut tree. This article explores the timeline of this tree’s growth. Stay with us to see how many years you will have a mature walnut tree.
The time for the growth of walnut tree varieties
Several varieties of walnut trees are different in terms of growth, hardiness, fruit taste, and growing Process. The English walnut (Juglans regia) originated from ancient Rome, also known as the Persian walnut, is native to Asia and Europe and is the most common type found in stores. They are resistant type and are not affected by late frost since their leaf process becomes completed later.
The Black walnut, native to North America, has a more robust flavor and is often used in baking and confectionery. Grafted plants can produce consistently high yields after just three or four years. The variety of ‘Franquette’ grows slowly. ‘Buccaneer’ and ‘Broadview’ are also late-leaf varieties that will thrive in colder climates like ours. In contrast, ‘Jupiter’ or ‘Esterhazy II,’ which have early leafing, do better in warmer temperatures.
Growth Timeline of the walnut tree
Factors Affecting Growth and Characteristics of Walnut Trees:
- Maturity and Nut Production: The growth timeline of walnut trees varies depending on the type and growing conditions. Generally, it takes 10-15 years for a walnut tree to mature and produce nuts. Some may start planting as early as 4-6 years, while others may take up to 20 years. For instance, English walnut trees produce nuts earlier than Black walnut trees.
- Self-Fertilizing Black Walnut Trees: Black walnuts are self-fertilizing trees that rely on wind for pollination. They have deep roots and should be planted separately from each other.
- Juglone Toxicity: Walnut trees release a toxic substance called juglone from their germinations, leaves, and husks, with the potential to impede the growth of neighboring plants. While detrimental to other plants, this acts as a defense mechanism and supports the walnut tree by preventing competition from invading plants.
- Seasonal Nut Drop: During late summer and early October, the nuts fall from the walnut tree, creating a mess on the ground if not picked up by humans or squirrels.
- Fruit Bearing Timeline: Black walnut trees typically bear fruit five to seven years after planting the seedling for food.
- Walnut Tree Plantations: Walnut trees take years to mature for timber production. Therefore, walnut tree plantations should be managed cyclically.
Growing Process of the walnut tree
Harvesting and Processing Walnuts:
- Harvest Time: In late August, you can harvest walnuts when the outer green husks begin to split, signalling the right harvest time.
- Drying and Storage: After harvesting, dry and place the nuts in a cold, dry location to preserve their quality.
- Mechanical Shakers: Gardeners often harvest using mechanical shakers, gently shaking the tree, allowing them to collect the nuts from the top of the trees without causing damage.
- Safe Collection: The automated shaking process ensures the safe collection of nuts without harming the trees.
- Harvesting Duration: The harvesting process, allowing for a steady collection of nuts, can extend until November.
- Husk Removal: After harvesting, the nuts’ husks or outer green layers are removed, and the fruits are left in a shaded area to reduce moisture content.
- Air-Dried Machine: An air-dried machine can facilitate the drying process.
- Grading and Sorting: In the packaging factory, walnuts are transported to different lines based on their type, colour, quality, and size. Both machines and humans participate in the grading process to ensure that only the highest quality nuts are sent for packaging.
The bottom line of how long a walnut tree takes to grow
Walnut trees are a natural gift regarding nutrients, woods, and beauty. Depending on the walnut tree’s usage, the time you consider for the walnut tree’s growth ranges between 6- 20 years. Growing a walnut tree requires patience and dedication, but the rewards are worthwhile.
