Feeder Roots
Horticulture expert Dr. Lelia Kelly defines the gardening term feeder roots. Plants have two kinds of roots: anchor roots that hold the plant to the ground, and feeder roots that get nutrients from the soil. Feeder roots usually grow in the top few inches of the soil. Feeder roots are very small and spread in the soil like a spider web around the plant. The soil under a tree is full of feeder roots for that tree. If you dig under the tree you are affecting the feeder roots.

Hybrid
Horticulture expert Dr. Lelia Kelly defines the gardening term hybrid. A hybrid is a plant that has been cross-pollinated or bred to emphasize certain traits. Usually a hybrid is created by people not nature. It is a cross between two different parents to try to get the best characteristics of each. Hybrids will often not breed true; their offspring will not be the same as the mother plant. To get another plant you must go back and cross the two parents again.

Chill HoursHorticulture expert Dr. Lelia Kelly defines the gardening term chill hours. This refers to the number of hours below a certain temperature that is required before a plant will flower. Chill hours are typically used to describe fruit trees. You should pick your fruit variety based on the number of chill hours where you live. If the plant requires fewer chill hours than your location gets, it will bloom in a warm spell in the middle of winter and the blooms will be killed by frost.
