I am pretty new to gardening(~6 months); I have a small terrace space with lots of potted plants (lemon, hibiscus, some herbs etc.).
I get soil(along with vermicompost) from various nursery suppliers depending on the feasibility/availability.
To a few questions I had asked in this forum, I was asked about what pH level my soil has, I understand pH level defines that where the soil lies on scale of acid to a base.
How can I know pH level of my soil, since I have got it from different sources its quite possible that different pots have different pH values? How does it affect the plant growth?
Do I need to take any caution on preparing the soil before a plant anything?
Lot of questions I have put together, let me know if I need an edit.
Thanks for your help.
