Hi, all. The lower leaves on my delonix are turning yellow in the center and then falling off. However, this is only happening to the leaves on the lower limbs. The leaves on top look very healthy and seem to be thriving. Right now I use rainwater to water mixed with bonsai pro fertilizer...
Or should I wait until sometime next year? I plan on transitioning the delonix to outdoors once the weather stays consistently warm, if that helps any. Thank you!
