Several plants struggling - Sollya heterophylla, Honeysuckle,

[obsidianlycan]

Hi everyone!

I have a Sollya heterophylla in a pot and a Dutch Early Honeysuckle in the ground. Both plants have bad yellowing and dropping older leaves, I had assumed due to the weather. We have had a wet start to summer, and assumed they were a bit soggy. Then the weather dried, but the problem continued. The honeysuckle I tested and sure enough, very depleted in N/a little down in P/but fine in K.

I would love your opinion, as I am worried about the amount of leaf drop. There are also red parts on the leaves as well, so maybe these poor things need some magnesium or other element? The flowers were Sollya also withering on the stem before even blooming, only maybe had 2-3 flowers. I am now getting more blooms on this now, after digging in some rotted manure and stepping up with some fertilizer but think the leaves are still dropping. The honeysuckle is blooming nicely now. Both have had a good amount of leafy growth at the start of the season at the top of the plant, probably sapping up all the goodness from the rotted manure I dug in back in April!

Also noticed this leaf drop is on older branches, that are transitioning to more woody. Maybe this is all to do with that, and I am being silly D:

How long have they been in their locations? They do look a little undernourished and N is very soluble so needs to be replaced regularly. Rather than digging around the surface roots that do the majority of the absorbing work, try simply applying the fertilizer and watering it in.
