I am looking for advise on care for our family Christmas Cactus that has been passed down in our family starting with a plant that was left on the farm by the previous owner in 1953. Starts were given to my Aunt in the early 1960's and stayed with her until her death in the in the early 2000's. The plant then went to my sister, then to me upon her death. The plant is in a 10" pot and has thrived, blooming every year until this spring when the leaves started to droop while still blooming. I am not sure what happened, if the issue was over watering? too much fertilizer? pests? other? I let the plant dry out over a couple of months and then started watering again without adding fertilizer to the water. The leaves are still droopy after several months and a small section seems to have revived marginally. The plant is still alive but clearly not healthy and happy. The cactus is about 2-1/2 ft in diameter and approximately 3ft long and is severely root bound in the pot. I have used Miracle Gro 20-20-20 commercial fertilizer for several years diluted to 1 tablespoon pre gallon of water. I am requesting advise on how to treat and care for the Christmas Cactus to give it the best chance for survival. What are your best recommendations for pest control, fertilizer, possible treatment for root rot or other possible problems? "How to" information and brand of products would be appreciated. Treatment will be indoors and needs to be safe for pets and people. Thank you. Diana Buell. <personal data hidden>
