QuestionI planted some roses (1 1/2 gal) and watered them adding B1 to the water. within days many leaves turned yellow. was this from planting shock or perhaps too much B1 in the water. The plants looked great before planting but now looks like they will lose 1/2 - 3/4 of their foliage. Should I have trimmed them back after planting or even now so not to stress them? I guess my real ? is can one over B1 when planting?
AnswerMany claims have been made regarding the properties of vitamin B1 when used on transplanting different plants. However there has been no definite proof that Vitamin B1 helps rose roots in any way. Many studies have been done but they have all failed to prove that vitamin B1 reduces transplant shock or stimulate any new roots. Tests have proven there was no difference in colour or the vigour of the plants and no difference between those roses that got B1 and those that didn't. On that basis I doubt the B1 did anything to your roses unless you didn't use enough water in the mix. Even then I fail to see what damage could have happened. As I don't know where you garden, perhaps it is the cold of the fall that is causing the problem. because the roses were is nice large container they should have transplanted easily without any problems at all. Except if the weather is starting into a cold winter.
