How Far Apart Should You Plant Plum Trees?

When it comes to planting plum trees, it's important to give them enough space to grow and thrive. The distance between trees will depend on several factors, including the size of the tree at maturity, the variety of plum, the rootstock used, and the soil quality. In general, most plum trees should be spaced between 12 and 18 feet apart, but there are a few things to consider before planting.

The Size of the Tree at Maturity

One of the most important factors to consider when determining how far apart to plant your plum trees is the size of the tree at maturity. Some plum trees, such as dwarf or semi-dwarf varieties, will only grow to be about 6 to 12 feet tall at full maturity. These smaller trees can be planted closer together, with a spacing of about 12 feet between trees. Standard sized plum trees, which can grow up to 20 or 30 feet tall, will need more space to grow and should be planted at least 18 feet apart.

The Variety of Plum

There are many different varieties of plums, and each one may have slightly different spacing requirements. Some varieties, such as Japanese plums, are known for their large, showy fruit and may require more space between trees to grow properly. European plums, on the other hand, are smaller and more compact and may be planted somewhat closer together. If you're not sure what variety of plum tree you have, consult with a local nursery or extension office for advice on appropriate spacing.

The Rootstock Used

The rootstock used for your plum trees can also affect how far apart they should be planted. Rootstock refers to the part of the tree that is below the ground, including the roots and the trunk. Different rootstocks can affect the size and overall growth rate of the tree, which can impact how much space it needs. For example, if you're using a dwarf rootstock, your trees can be planted closer together than if you're using a standard or semi-dwarf rootstock. Again, it's a good idea to consult with a nursery or extension office to get specific advice on rootstock and spacing.

The Soil Quality

The quality of your soil can also impact how much space your plum trees need. Soil that is rich in nutrients and has good drainage will generally support healthier, more vigorous growth than soil that is compacted or undernourished. If your soil is of poor quality, your trees may need more space to grow effectively. On the other hand, if you have high-quality soil, you may be able to get away with planting your trees a bit closer together.

Final Thoughts

When planting plum trees, it's important to give them the space they need to grow strong and healthy. While most plum trees will need to be spaced about 12 to 18 feet apart, there are many factors to consider in determining an appropriate spacing. If you're not sure what variety of plum you have or how far apart your trees should be planted, consult with a local nursery or extension office for advice. By planting your plum trees properly, you'll be setting them up for success for years to come.
