Care of Existing Crocus
About 3 1/2 years ago, I planted crocuses in my yard in 12 x 15 inch rectangles and had a nice display for two years. Then, last year there were just a few blooms. This year, I had many plants, but only two blooms. What must I do?

Either there is a phosphorus deficiency in the soil or the corms are overcrowded. Try giving them a high phosphorus amendment or fertilizer (like bone meal) and dig a few up to see if they are too crowded.
