Are morning glory plants adversely affected by fertilizers?

Question

Just wondering.... I have a vine that grows outside and I fertilized some Cosmos next to the vine. The vine died. New growth has begun since then. But now I'm afraid to feed the Cosmos any fertilizer now.

I THINK the vine is related to the morning glory family--- However, this vine has a lacy type of leaf and has white flowers. To be honest, I don't know what it is. It just has blooms that look like the morning glory family. Any clues? I'm in SW AZ.

I can only assume you didn’t plant the vine but it grew on its own – since you don’t know what it is.

Morning Glories prefer poor soil and if you fertilize them too much you can end up with vegetative growth at the expense of flower production but I can’t imagine how fertilizer would KILL the vine unless you burnt the roots with excess fertilizer. It had been growing fine up until that point – No?

It is also possible that one of the neighborhood dogs peed on it.

One recommendation usually made and adhered to, is to grow plants which thrive under the same growing conditions, together.

If you are growing Cosmo’s which like it hot and dry under blazing sun (and should only be watered ‘artificially’ if they start to wilt) – you should cultivate plants that prefer the same conditions in that section of your garden.

I would think Cosmo’s and Morning Glories would grow well together – so I guess I really don’t have an answer.

If the fertilizer burnt the roots of the vine it surely would have affected the Cosmo’s as well.

I’d blame the neighborhood dog that’s left to wander.

Or it may be a vine that does not like the same growing conditions as your Cosmo’s and decided it had had enough.

Sorry, no clue.
