TYLER, TX (KLTV) - Adding leaves and other organic material into your garden soil makes a richer, improved soil.
Most leaves would be great to add, except the leaves from pecan, hickory and walnut.
According to the Texas A&M AgriLife Extension Service in Angelina County, the biology of some plants produce a chemical to protect itself and keep other plants from competing for water and nutrients.
Walnut trees are especially known for this.
Many East Texan gardeners know to steer away from using walnut, hickory or pecan leaves in their garden.
The use of oak and other leaves as well as pine needles hasn’t produced the same problem and certainly builds your soil.
Use organic matter - but shy way from using the leaves from pecan, hickory and certainly walnut.
