I have a large dahlia that has been doing very well. Now I notice a lot of dried and yellowing leaves. The stems are getting leggy. Some stems have just a a couple of leaves. I have been watering it faithfully because of the extreme heat. I hate to lose this plant, however it is just not as full as it was. Any ideas? Thanks
Dahlia getting leggy and losing leaves
Can you post some pictures? Too much water & too little water could both be possibilities, they have similar symptoms. You might try doing the "finger test", stick your finger down a few inches into the soil and see how wet it feels. If it's really dry then underwatering is more likely, or if it's wet then overwatering is more likely. I know it's been hot lately but it's still possible to overwater things if they're in soil that doesn't drain well. Or it's of course possible that you're not watering enough--especially if it's in a container, if you've been watering in "sips" instead of giving it a thorough watering it might not be getting enough.
