pH Chart for various plants.

In my experience, the pH of the soil is a major deciding factor to a healthy plant.

Good chart. It has a lot to do with it's capability to absorb key nutrients/micro nutrients.

Mental note. Lol

Read up on the plant in question. I just gave two hibiscus (gallon each), of some ball swinging, high potassium, chemical fertilizer...12-55-06. Drop of Super Thrive.

They don't need it. In April YES. Not in November. I read that after the fact.

Second mental note. When the hibiscus were put in the ground. I should've added Dolimite Lime to the hole. Dolimite keeps the PH of the soil at a neutral 7. The zone that Hibiscus likes to use nutrients.

Come spring, Ill add dolimite to the top soil. Water down with PH corrected water.
