Q.My Agapanthus Plant Is Not Flowering As Previous Years Can You Assist?
I was looking on your website about all the very helpful information you have regarding the care of an Agapanthus plant, and wondered if you might be able to assist me regarding one of several plants I have in my garden. This particular plant is about 10-12 years old. It has flowered every year without any issues and then suddenly this year all that have appeared are two flower stems. As you can see from the photo attached a large number of the leaves seem to have dried or even died and I cannot fathom what could have caused the plant to go this way. I have not done anything differently to this particular plant than the others we have in both our front and back garden and they have all flowered. Any assistance or suggestions from you as to how I can get this plant back into full flower next year would be very much appreciated Yours Sergio Martini
