I have a very large staghorn approximately 25yrs. old growing completely around a grapefruit tree. How do I remove the pups safely and start new plants. Also what is the best fertilizer for these plants. Thank You,
You should find all the info with the link that is supplied. I have three of these that are not anywhere near the age of yours (8years). The only fertilizer they are given is a weak, very weak drink of 20-20-20 orchid fertilizer and that is only once a month. What I do give them is a good size chunk of banana peel as they love potassium. Hop this helps a bit.
