How fast your palm trees grow ultimately depends on the species of palm. For example, some species will grow up to 2-3 feet per year. Other species, meanwhile, may only grow up to 5 feet after several years. Growth rates of these palm trees depend on a variety of factors, including location, pruning, fertilizing, and irrigation.
Palm Tree Growth Rate
You can expect healthy growth rates for your palm trees when conditions are ideal. The conditions refer to a proper amount of fertilizer, pruning, and watering. Different species have different rates of speed at which they grow. Let’s take a look at the different species found in Arizona below!
The King Palm is considered a fast-growing palm tree. These trees grow quickly in soil featuring plenty of nutrition and good moisture. The King Palm’s growth rate is about 2 feet each year. The growth rate can actually be faster when the tree is planted in partial shade as it will grow quicker towards the light.
Planted in USDA hardiness zones 9-11, the Queen Palm will grow 2 feet each year. This means if you purchase a 15-gallon plant, you can expect the tree to be about 25-feet tall in just 10 years. The Queen Palm actually grows faster than the King Palm.
Also known as the European Fan Palm, the Mediterranean Palm grows rather slowly. These trees grow about 6 inches each year and reach their mature height of 20 feet over time. They are very popular trees, renowned for their unique bark and fronds. They make great additions to most residential landscapes.
Under ideal conditions, the Foxtail Palm can grow 2-3 feet each year. They can eventually reach a mature height of 30 feet in about 10 years. Foxtail Palms feature a deep root stem that helps make them drought resistant.
Mexican Fan Palm
A common and fast-growing tree found in Arizona is the Mexican Fan Palm. These trees can reach heights up to 100 feet, often making them far too large for most residential properties. 4 feet of growth each year is expected with these trees.
