Why Didn’t My Silver Lace Vine Bloom This Year?

Question

My silver lace vine is at least five years old, probably older. Last summer it bloomed for the first time. This year it did not bloom. It was spectacular last summer. Thanks

Answer 1

I suspect that the flowering cycle could have removed the remaining potassium and phosphorus Leaving more nitrogen. This can also acidify the soil, which will make the potassium and phosphorus less available.

Alternatively, soils that are overly rich with nutrients will cause a shortage of growth AND flowering for this invasive vine.

Fortunately, you can test these things:
