|I have 2 Lily of the Nile plants that have been in our front yard for about 4 years now. They get morning shade and afternoon sun. The last few months their leaves seem to be yellowing, especially @ the tips. The plants are in bloom @ their fullest right now, but the yellowing leaves are not attractive. Our neighbors across the street have the same plants, under their window and they are deep green leaves. Some people tell me I am watering too much, while others say they need more water...HELP! What am I doing wrong? I water the entire yard 2 times a week, 1 hour each time. So I do a deep watering, but only 2 times a week.
Any suggestions would be great......this is really frustrating!
Thank you for your time......
|Lily-of-the-Nile is Agapanthus, an adaptable perennial that grows in full sun, or in as little as 3 hours of sun a day. It thrives in loamy soil but will grow in heavy soils, and gets along with very little water, even in the summer time. I suspect that you're overwatering your plants. Try watering only once every 2-3 weeks, watering deeply and thoroughly so the entire rootmass gets wet. You can feed your plants a diluted liquid fertilizer about every 4 weeks during spring and summer to help them green up a bit, or you can mulch the top of the bed with compost to provide nutrients over the entire growing season.|
