Hey guys,
I planted a cascade rhizome about a month ago in a big barrel with some high quality potting soil and some compost. I've seen terrific growth and development until about a week and a half ago when the lower leaves began wilting and turning yellow. The plant has achieved a height of nearly 4 feet.
Since then, several leaves have curled up and died and are now brown and hanging on for dear life. I have been checking the soil with a moisture/pH meter and have kept the moisture level at a 6 (medium) and the pH is around 7. They have been getting as much light as possible in the daytime and I have pampered them with some grow lights in the morning and dusk hours, achieving about 16 hours of light daily. I really expected them to be doing great, but for some reason the leaves are still dying.
Today the plant got much worse and now 6 leaves have either died or are near death. I have no clue what's happening, but I was first thinking potassium deficiency and now I'm leaning towards it being too hot. Today was about 75 and sunny and the soil was on the dryer side. I've attached photos of the casualties.
I have several questions for anyone with a bit of experience.
1. Should I cut off the dying leaves?
2. Should I try giving it more potassium? I already gave it a very diluted sip of some potash to no avail.
3. Should I let the plant have more dark time?
4. Is 75 degrees F too hot for a 3 foot tall plant and should I start putting the plant outside at night to give it more cool time?
5. Can anybody help me!??!
Thanks!
