I planted 4 roses (from 1-gallon pots) about 5 weeks ago. Only 1 out of 4 appears to be thriving. I forgot to apply a vitamin B-1 solution at the time of planting but applied it to the soil the next day. I fed all my roses one week ago. The area where I planted the new roses is the same area where I have 12 established roses that are showing healthy growth since pruning. I dug the holes to the proper width and depth before planting, and backfilled with a mixture of existing soil and amendment. It has been unseasonably warm so perhaps I did not water enough. Do you have any tips for saving my transplanted roses? Thank you for your advice.
