I have my hoyas for years and I have only had 3 that have bloomed, H. carnosa, H. multflora, H. obovata. Can someone give me some advice on how to get the others to bloom. I have a lot of Hoyas at one time but I lost a lot of them due to illness and not being able to take care of them. Some of them was determined to survive until I was able to take care of them. I have 12 left:

H. merridithii

H. obovata

H. melflua fraterna

H. carnosa krinkle

H. fungii

H. macgillivray

and 7 lost tags.
