Then suddnely I noticed the pots were beginning to sprout mould after a week or so. And I noticed the mix was turning mouldy in the original sack. The nursery accepted my returned bag and gave me a new one. Same result. I complained to the nursery. They told me that the company had changed their formulation. I told them that they should let the producer know that their new formulation turns mouldy. I never bought that brand again. The dealer also graciously replaced my bulbs. David E.
