Certain plants can interfere with each other's growth through a process known as allelopathy.
Allelopathy refers to the release of chemicals by one plant that can inhibit the growth of other nearby plants.
These chemicals can be released through the roots, leaves, or other parts of the plant and can affect neighboring plants in various ways, such as hindering seed germination, root growth, or overall development.
Sunflowers
Sunflowers release allelopathic chemicals that can inhibit the growth of certain plants, including beans and potatoes.
Sage
Sage plants can produce allelopathic compounds that affect the growth of nearby vegetables, such as tomatoes and cucumbers.
Trees in the Eucalyptus genus
Eucalyptus trees release allelopathic compounds that can inhibit the growth of many plant species, including some common crops and pasture grasses.
Blackberry
Blackberry plants can produce allelopathic chemicals that inhibit the growth of other plant species in their vicinity.
Wheat
Some studies suggest that wheat crops can release allelopathic compounds that affect the growth of neighboring plants.
Marigold
Certain marigold species have been found to produce allelopathic chemicals that can suppress the growth of other plants.
