|What soil PH do agapanthus prefer - what fertilizer should I use on agapanthus and when should I apply ? I have just purchased several monrovia grown agapanthus from Hester & Zipperer here in Savannah.|
Agapanthus is tolerant of a fairly wide range of soil pH, but something in the 6.5 to 7 range would be ideal. Use a complete fertilizer product periodically in moderate doses. I like to use a turf type fertilizer with a 3-1-2 ratio of nutrients (such as 15-5-10) at a rate of about a cup per 50 square feet of bed area, applied in spring, early summer and mid summer.
Thanks for the question. Please stop in again soon!
