Suggested Acidity Levels

The following plants perform better in a soil with a slight acidity level of PH 5.5 6.0. A small difference in acidity levels seems to make for much better growth due to the fact that these plants can use the available fertilizer more effectively.

The following plants require strong acid soil with PH 4.5 5.5. Most of these plants are surface rooters and can not take up fertilizer unless the acidity is in the correct range. Yellowing of Rhododendrons is a classic example of that phenomenon.
