Garden plants that don't let other plants grow properly: Pick your plants carefully

Certain garden plants have the ability to inhibit the growth and development of other nearby plants. 

These plants are often referred to as "allelopathic" plants, and they release chemicals or compounds into the soil or surrounding environment that can suppress the growth of neighboring vegetation. 

Here are some examples of allelopathic garden plants.

Black Walnut

Black walnut trees produce a compound called juglone, which is toxic to many plants, including tomatoes, potatoes, peppers, and certain fruit trees.

Sunflowers

Sunflowers release allelopathic chemicals through their roots, which can inhibit the growth of nearby plants.

Juglone-Producing Trees

Besides black walnut, other trees in the walnut family, such as hickory and butternut, also release juglone and can impact neighboring plants.

Barberry

Barberry bushes produce chemicals that can hinder the growth of nearby plants and affect soil microorganisms.

Eucalyptus

Eucalyptus trees release allelopathic compounds that can suppress the growth of many plant species in their vicinity.

Mint

Mint plants, especially invasive varieties, can inhibit the growth of other plants due to their aggressive nature and release of allelopathic compounds.

Sorghum

Sorghum is a cereal grain that produces allelopathic compounds that can inhibit the growth of nearby plants.

Rye

Rye cover crops are often used to suppress weeds, but their allelopathic effects can also impact the growth of desired garden plants.
