Q.I was recently told that if you have no rainwater for lime hating plants you can add vinegar to tap water. Would this work and if
so what would be a suitable amount of vinegar to add? Thank you. I have recently bought a Gardenia Jasminoides and hope to keep it alive!

Here are some other tips to lower the soil pH. For vinegar, water plants several times with a solution of 2 tablespoons vinegar to a gallon of water.
