Well theres no such thing as "saving too much mana" but there is a thing called being "passive".

Zyra is extremely good at zoning and essentially destroying an opponents chances at farming due to her insane amount of zoning, shes alot like when Ziggs has a clear shot through a minion wave, she will funnel you into a particualr area, and line up her combo right in that zone that your FORCED to move through, thus, killing you.

Support Zyra works the same way, but with less focus on killing, more on Zoning out the ADC and securing a kill with her knockup-snare deal when an enemy is low. Shes really strong right now, and I dont know why she isnt picked.

But overall, she didnt really need to spam her plants or really even use them past mini-wards cuz they are frankly useless on support zyra (in my opinion) unless your fighting, and if your fighting you run a high risk of them taking a kill. So its better off to not even sue them. But she shouldve been forcing plays cuz of her damage early on plus her snare so I think she is guilty of not being aggro enough.
