Fertilizing winter overed Princess Lily
I have several 10 inch pots of Alstroemeria Princess Lilies which I wintered over in a combo of unheated porch and cool basement. The pots are lush with growth. I`ve read the first growth is support stems and the flowering stems will appear after those.
The plants are in a soiless mix and the stems about 5 inches high. I fertilized with Miracle Gro about a month ago. What should I be using as fertilizer... I`ve read advice suggesting low nitrogen such as tomato or an annual flower solution like Miracle Gro.
