If you’ve ever wondered, how big is a mustard tree? you’re in the right place! Mustard trees are fascinating plants with a variety of uses and growth habits. Whether you’re considering adding one to your garden or just curious about their size, this article will give you a clear picture of how tall and wide mustard trees can grow, along with helpful tips on their care.
What Is a Mustard Tree?
Before diving into size details, it’s good to clarify what a mustard tree actually is. Unlike the common mustard plants grown for their seeds, mustard trees-sometimes called toothbrush trees-are evergreen shrubs or small trees native to regions like Africa, India, and the Middle East. They are known for their spreading growth habit, weeping branches, and green to yellow blossoms that turn into edible berries in the summer.
These trees are not the source of the mustard seeds used in cooking but have their own special uses, such as natural fibers for toothpaste alternatives and traditional teeth cleaning sticks. They thrive in warm climates and are suited for USDA hardiness zones 7 to 11.
How Big Is a Mustard Tree?
The size of a mustard tree can vary quite a bit depending on the environment and growing conditions. Typically, mustard trees grow to about 20 feet tall, but some can be as short as 6 feet or reach impressive heights up to 30 feet! Their spread is also notable, as they have a wide, spreading habit that makes them excellent for shade.
Size Range Summary:
– Height: 6 to 30 feet (average around 20 feet)
– Spread: Wide, with a weeping branch structure
This means if you’re planning to plant a mustard tree, make sure you have enough space for it to grow both upward and outward comfortably.
Factors That Affect Mustard Tree Size
Several factors influence how big your mustard tree will get:
– Climate: Warm regions with low humidity are ideal. In cooler or less ideal climates, growth may be slower or the tree may stay smaller.
– Soil Quality: Well-draining, nutrient-rich soil supports better growth.
– Watering: Regular moisture helps the tree reach its full potential, but it’s fairly drought-tolerant once established.
– Sunlight: Full sun exposure encourages healthy growth and flowering.
– Pruning: Regular pruning can control size and shape, encouraging bushier growth rather than tall, leggy branches.
Mustard Plants vs. Mustard Trees: Size Differences
It’s easy to confuse mustard trees with the common mustard plants grown for seeds and greens. Mustard plants, such as field mustard or Sinapis species, are generally much smaller:
| Plant Type | Typical Height | Typical Spread |
|---|---|---|
| Mustard Plant | 1 to 6 feet (30-180 cm) | 1 to 3 feet (30-90 cm) |
| Mustard Tree | 6 to 30 feet (1.8-9 m) | Wide spreading habit |
Mustard plants are annual or biennial herbs, while mustard trees are woody perennials with a much larger size and longer lifespan.
Growing and Caring for Your Mustard Tree
If you want to grow a mustard tree, here are some friendly tips to help it thrive:
– Choose the Right Location: Full sun and space for spreading branches are key.
– Soil Preparation: Amend soil for good drainage and fertility.
– Watering: Water regularly during establishment, then reduce frequency.
– Pruning: Shape your tree annually to maintain size and encourage dense growth.
– Protection: In colder zones, protect young trees from frost.
Interesting Facts About Mustard Trees
– Mustard trees have been used traditionally as natural toothbrushes.
– Their fibers are used in some natural toothpaste products.
– The berries are edible and enjoyed in some cultures.
– They provide shade and can be ornamental, despite their irregular shape.

Mustard trees are unique plants that combine practical uses with a striking presence in the garden.
Mustard trees typically grow between 6 and 30 feet tall, with an average height around 20 feet, depending on variety and growing conditions. Their wide, spreading branches make them excellent shade trees in warm climates. Whether you want a small tree or a larger specimen, understanding their growth habits will help you create the perfect spot for them in your garden.
