Thiscomplete guide explains the answer to the question, how long does it take for a tree to grow, and explores the reasons for tree growth rates for some common species, as well as the factors affecting the growth rate.
Some trees, like the Sugar Maple and American Sweetgum, have an average growth rate, reaching 10-15 ft high in about ten years. Others are famous for taking less than ten years to accomplish 90% of their mature height.
Interestingly, you will discover that the slowest-growing members of the same species usually live longer than their counterparts. While the fastest growers grow taller and grow seeds faster, the others tend to ease their way into old age.1
Scientifically, the faster a tree grows, the more energy it puts into developing taller and gets exhausted earlier than other slow growers. They also take up more space, are the first to mature sexually, and are more susceptible to disasters like fires and floods, leading to earlier death.
On the other hand, the slower-growing trees of the same species take their time investing in structural integrity, developing stronger wood, and becoming more immune to diseases and pest infestations.
Trees need water to photosynthesize, making moisture one of the most crucial growth elements. It is the primary component of the plant cells, necessary for transporting essential minerals to the cells, and facilitates seed germination into seedlings.
The only exception is for trees that grow better under partial sunlight or shaded spots. However, if your tree loves the sun, it helps to plant it under full sunlight; otherwise, it will have stunted growth.
Each tree grows best in a specific season, but one common factor is that most have a drastic growth decline during winter. The conditions are too harsh for the plant, and if your region experiences punishing low temperatures, you expect little growth around that time.
Most prefer planting from August to October or later in the year, depending on their region. Trees growing in tropical areas or warm weather can fully grow within less time than those growing in colder climates, which can take longer than a century based on the plant species.3
If doing it yourself, it is paramount to know the difference between the branch and the trunk wood. Interfering with the trunk can cause issues with future growth, but pruning the branch means that your tree will grow back faster.
Another common mistake tree owners make is topping the tree. Here is where you cut back the branches to the trunk, which causes severe tree damage; the twigs may fail to grow or come back weaker and more vulnerable to harsh weather.5
The two main ways to grow a tree in your home are from seeds or seedlings. While others prefer using seedlings, which seem more convenient, others would instead start with seeds, and there are several advantages to it.
Another upside is that you can select the strongest of the bunch that will grow into healthy seedlings, and there are chances of coming up with new tree breeds. You can grow almost anything from seeds since trees develop nuts or fruits that are similar to or better than the parent.
Some favorites include the Heartnut, a walnut species, and the Antonovka Apple; the goal is to pick seeds from a plant with the features you are looking for, not weak plants that will birth stunted offspring.6
The best time to pick seeds is during autumn when they have fully matured, then prepare them for planting by cleaning and drying them. Alternatively, you can buy them from reputable local stores or import them.
Given how vital water is for the growth of trees, providing more of it encourages them to grow. Moisture helps trees transport food and minerals within the cells and lacking it means the growth rate will reduce.
Trees grow better when there are necessary nutrients in the soil, and you can supplement the levels by adding fertilizer or compost, especially in spring. Plants grow better with nitrogen-rich fertilizer since they will create sufficient food and have enough energy to grow faster.7
Intense competition is the primary reason for low growth rates. Weeds and other closely-growing plants struggle for the scarce resources with your trees, robbing them of the necessary moisture and nutrients.
In a contrasting case, sometimes the tree grows faster than you expect, and you may want to slow down the rate. The best solution is to use hormone regulators, which effectively reduce the rate of growth hormone production.
The growth rate gradually starts declining due to the interference with the release of gibberellic acid and other components. The regulators stop trees from growing excessively tall and manage the speed of foliage growth.
If you find your tree growing unusually slower than its counterparts, the best you can do is to provide everything it needs, creating a conducive environment. If your region experiences scorching heat, you can frequently water your trees to replace the moisture lost via evaporation and transpiration.
All plant types, including hardy desert species, need water to survive, and you can tell when to water whenever the soil dries up. Secondly, you can check that the tree is in a safe spot where it can receive unlimited sunlight and that there are no shading buildings or objects nearby.
Trees need at least six hours of sun, and you can carefully plant yours in the open where there is no shading. It also helps to enrich the soil with fertilizer and compost to boost its growth hormones and watch out for pests and diseases that usually inhibit growth.
Leaves will later form on these fresh sprouts, facilitating their growth. However, this only happens if you strategically plant the tree where the soil is fertile and there is enough sunlight and water access.
All plants initially start from seeds in the ground. Watering, fertilizing the soil and providing warmth facilitate germination as the seeds soften from their rigid shells and start developing roots within a few weeks.
With patience, care, and maintenance, your tree can reach its full height and start flowering and producing fruits. The time frame, however, will vary based on the species and other prevailing conditions.
An Apple tree can reach maturity at 2-10 years, based on the species you plant or whether you grow it from a seed. Starting from seed typically takes longer since you must wait for the tree to complete its germination and seedling stages.
To those wondering, how long does it take to grow a Christmas tree? Each of the various types of Christmas trees has individual growth rates, but generally, the species take 4-7 years to reach at least 5 feet high.
Pine trees are a favorite for homeowners because they grow tall quickly, making them perfect privacy hedges and fences. Typically, pines reach maturity within 25-30 years, after which their wood will be ready for harvesting.
Most pines have a fast growth rate, reaching up to 2 feet yearly, and some grow to a staggering 150 feet high. The Australian and Canary Island Pines are some of the top choices for trees that grow tall fast.
Oaks are known for their slow growth rates from their saplings to become self-sustaining. They usually take 5-6 years before they are independent and take decades to grow fully, with the average time to produce viable acorns being 20 years.
On average, bonsai trees can take 5-15 years from a seed/sapling to full maturity, but some species can extend to 30 years. They are usually slow-moderate growers, attaining 12-18 inches in height annually.
Lemons are the most cold-sensitive citrus trees, and you want to avoid the punishing winter weather. Additionally, they hate the sweltering summer temperatures, meaning spring is the best time to plant.
The goal is to avoid planting in frozen soil, and there is no frost risk, preferably towards the end of February and early March. However, you can grow one all year round indoors or outside in tropical regions.
Among the different types of trees, the fastest-growing tree in the world is the Hybrid Poplar, which grows at an impressive rate of 8 feet annually. Homeowners find it ideal for a privacy hedge or fence because it effortlessly towers above other trees.
The slowest-growing tree on record is a Canadian White Cedar from the Great Lakes region that grew to only 4 inches in 155 years, weighing only 0.6 ounces. Other slow-growing trees include the Bur Oak, Eastern Hemlock, and Japanese Maple.
Germination of a tree from seed can take 1-3 weeks or several months based on the type and prevailing environmental conditions. The seedling stage after germination comes next when a tree has sprouted and started growing taller.
Maturity comes later after years of constant care allowing the tree to reproduce. The entire process from germination to maturity can take a decade to 30 years, depending on the tree species and how well you care for it.
Magnolia trees need care and maintenance, especially sensitive seedlings. While most species can survive under sweltering summers and water shortages, the young ones need regular irrigation until they are self-sufficient, preferably the drip method.
They also need fertilizing to grow faster and healthier, and you only need to prune them a little except for damaged branches or when shaping and styling for landscaping reasons. These are the things needed for proper Magnolia tree care.
When looking for trees to plant around your home as privacy hedges, you consider their full height and growth rate. When you have settled on particular varieties, the next step is to grow them from seeds or seedlings, with the former taking longer since you must wait for germination.
Most trees take 20-30 years to mature depending on the type, the surrounding conditions like the climate and seasons, and how well you care for them. Generally, the more comfortable the plant is, the faster it will grow.
Therefore, if you are worried about how long does it take for a tree to grow, remember that you also have a significant role to play in how much your trees thrive and reach their full potential.
