Landscaper Guide to Plant Spacing

Last Updated on April 12, 2022 by Kravelv

Landscaping properly requires a lot of adjusting that many people don’t realize they have to do. For example, planting flowers requires more than just the physical work. There is a lot of science involved. Knowing where to plant different types of plants and varieties is important to ensure the survival of your yard. If you don’t, you can end up with jumbled messes of plants, or other plants that will not be so nice to their neighboring plants, taking the nutrients right out of them, thus leaving you with a plant homicide or genocide on your hands.

The Importance of Spacing

When you’re planting an item, you need to actually plant the center root, starter plant, bulb, or even seeds apart from others as they direct on the package or a little more, so you can have plants that are spaced enough apart that when they’re fully mature, they can still have some breathing room.

One example of this is flowers like mums or sedum. Since each plant can grow about 4 inches tall, but flower out to about 15-18 inches, you want to plant each plant approximately 15 inches apart.  If you’re starting from seeds, you may want to even plant them about two feet apart.

Tree Spacing

Tree spacing is important. Keep the smaller decorative trees closer to your homes and anticipate about five times the width of the sapling or premature tree you purchase. You want to actually double or triple the space from one tree to another in most cases so the roots don’t get intertwined as well. So if you plant a dwarf apple tree that can grow about 4 feet wide, be sure that you put at least 4 feet in between trees of the same type. If you’re trying to plant different types of trees, especially fruit-bearing or flowering types, you generally want to plant those twice as far apart.

Follow Seed Directions

Even when you’re using a starter plant, you can generally look up or look at the package and see how far they advise you to plant them from other plants. You need to factor in varieties of plants as well though. Some plants and flowers, shrubs, and more are more invasive underneath the soil and can take away nutrients that the other flowers and plants need to thrive. Therefore, it’s important also to know what to plant where and what plants you can grow next to each other.
