How does pH Affect Your Tower Garden Plants?

How pH affects plants Tower Garden

pH stands for Potential Hydrogen. It’s a measurement used for growing in both soil and soil-less gardening. A balanced pH for water is 7. Anything below 7 is acidic and anything above is alkaline. Most plants do best with a slightly acidic pH of 6, but anywhere between 5 and 7 is good for most plants in your Tower Garden.

A balanced pH helps plants to take up the nutrients in the water. If the pH isn’t correct plants won’t be able to use the Mineral Blend (nutrient) you put in your Tower Garden. Plants won’t wither and die overnight if the pH isn’t correct. The affects will be gradual. Growth will slow. Leaves might wither over time and you might get brown spots on the leaves.

What to do if pH isn’t correct?

If you see that your plants aren’t doing well, check the pH. If it isn’t correct, then adjust it as soon as you can. See Weekly Maintenance of the Tower Garden for how to adjust your pH. Once the pH is correct, snip off leaves that don’t look good. New, healthy leaves should grow back. If incorrect pH goes on for too long, the plants won’t recover. You’ll need to clean out your Tower Garden and start over with new plants.
