Here are old, established hostas that have always done very well, even with my neglect. Never fertilized, never watered
except when it rains. This summer has been brutal with temps sometimes over 100, often in the 90s and until recently, nearly no rain. I'm assuming it's the heat and lack of water and that next year they'll be fine? When should they be fertilized, or do they need to be?
