Q.get a pink or showy lady slipper to bloom again
How do I get a pink or showy lady slipper to bloom again? I planted a pink lady slipper and waited about seven years. My wife moved it to a slightly more sunny location but still in dappled sunlight under large trees. The location is on a hill with good drainage. The next year we got a single beautiful blossom. For the last 3 years, we have had a vigorous good looking plants but no blooms. Any suggestions for fertilizer, bone meal, soil acidifier, etc. that might get it to bloom again? I think the plant was originally cultivated in Canada.
I have listed a link with a few tips on mulching, fertilizing and proper growing conditions.
My mother in law only waters hers with water from the outside untreated water pump and mulches with old leaves.
