We just recently purchased several fully grown garden flowers (denver daisy and 2 very bushy and full of blooms foxglove.) The denver daisy stopped producing in the first week, and the flower buds turned brown and never bloomed (opened up). I took the plant back and got a refund. Then two weeks later, the two foxglove I purchased seem to have crown or root rot, the roots looking similar to the denver daisy purchased by the same company. Since I had already planted all three potentially infected plants in my very large years in planting garden, is my overall garden now at stake??
The plants may have failed for many reasons. Transplant shock or perhaps they were planted too deep with the crown buried beneath the surface of the soil. Perhaps they got too much water or they were sprayed with cold water instead of the water being directed at the soil…spraying the plants with cold water from a hose shocks them…and can be fatal to a plant already under stress. Also, plant diseases, if there were any, are often specific to that plant family so there is no reason to believe that the rest of the plants are in any jeopardy.
