Soil PH Preferences for Potted Plants

How to use the information in the chart. To make the best of the lists, group plants with similar soil requirements. Also, avoid planting trees, shrubs, vegetables, flowers and herbs in an unsuitable pH. For example, lilac bushes won't do much if their feet are sitting in acid soil, while potatoes will be dotted with scab if the soil is too sweet.
(Note: Don't use them as your only guide because other factors may lead to poor performance.)

Plants are listed here in columns according to the pH level they prefer. Note that some are very sensitive to pH levels outside their tolerant range, in which case they will appear in more than one column even though they are coloured yellow as being "sensitive".

This green background means that this is an ideal pH for this plant.
