Poinsettia plant ph
We purchased a moisture and ph meter to test our poinsettia plant to see when it needs water. What is the ph reading that the plant needs to see if it needs watering. Tom

The pH will not give you any indication on if it needs water or not. It can only tell you if the soil is alkaline or acidic, which will help you to see what the plants may be lacking in, nutrient-wise. The moisture readers are often hard to use, and will only work if the soil is moist. The best way to check whether it needs water or not would be to put your finger down into the soil about 2 or 3 inches. If it is dry passed this point, then it will need water. If there is still moisture then I would wait a day or so. That is the most reliable way I have found to check moisture level in the soil.
