The Orchid Doctor Articles under the Heading Phosphate

Phosphate Comments
PHOSPHATE: Characteristics It determines the new, lush green growth and the formation of seed; it tolerates a pH between 6 and 7.5 only: at pH 6 the growth is leggy, weak, harrow and breaks easily, leaves do not hold up; above a pH 7.5 the plant is progressively starved of it. OA78-51; this is very misleading. OWD 0
PHOSPHATE: Properties It plays a complex role; forms many insoluble and slightly soluble compounds; their solubility is affected and altered by the pH of the media reaction; under conditions of slight to moderate acidity added phosphates have a relatively long life; it is not readily leached out; it is used in small quantities by the plant. OD67-219 0
