I bought an outdoor tuberose begonia at a local nursery. First, the the blossoms rotted rather than dry.. Next, the plant collapsed. The outdoor begonia was on an outside covered porch. The door to the porch was opened once daily, to pick up the morning newspaper. Now I have wilt on some long term coleous, definbachia, and indoor ivy. I am concerned also about possible wilt in another long term fuzzy leafed purple flowered plant. I have had some of these plants for over 30 years and now they are in wilt. Could losing my old plant friends be related to the begonia wilt? I have some saved starts in my garage. If this is a serious wilt problem when can I return my saved plants?
