Culling the Garden

Save Seed from the Best Plants.
It is very important to save seeds from the healthiest, robust, and most superior plant specimens.
After seedlings are transplanted into a garden frequently check them for weakness, deformity, disease, susceptibility to pest infestation, or any other inferiority. Any plants showing these negative traits should be culled (removed) from the garden bed.
By removing these undesirable plants early on in the growing season they will never mature to flower and thus they cannot pollinate other plants and pass their poor genetic traits onto subsequent generations.
