Q.Planting lilac bush
I only have a patio. Can I grow a lilac bush in a large container and what soil would they prefer?
Lilacs tend not to want their roots constricted and may not bloom if this is the case.
It can be challenging, but can be done.
Lilac won't tollerate acidic soil, and most commercial mixes contain peat.
You can add 1 cup of dolomite lime to a 2-cubic foot bag of potting soil will raise the ph and add calcium and magnesium to the soil.
Add 1 cup of lime each spring to the pot soil.
Use a large and heavy pot, clay would be best to pot up the Lilac.
