I was talking to my neighbor the other day and she told me her plants are doing really bad this year. She planted some Gernaiums and use Bacopa as a filler for her window box. I have been noticing her plants doing worst and worst every week but I was thinking she probably doesn't have time to do the the normal maintenance (watering, pruning, etc.). After talking to her, she told me the reason is because she used cheap dirt. She made up for it by adding fertilizer but the plants just never bloom and they look pathetic. Is it true that cheap dirt is bad compare to the brand name potting soil?
This is a picture of her plant that's not doing so good
