Q.Non-blooming sky vine
We planted the sky vine in early March – in JAX, FL, and did have a very cold couple night after that. The leaves took a hit and they fell off – but have recovered completely. The plant is doing extremely well in growth and foliage. But we have not gotten any buds or flowers since planting. Could it have been the cold/light frost got the early set buds or is there something else that it needs? Wondering when the buds set for blooming each year?
Most likely the cold effected the buds and blooming for this season.
Also Sky Vine needs plenty of sunshine.
Also you may have to much Nitrogen in the soil. This will cause lots of greens and no flowers.
A lack of Phosphorous can easily be corrected with the addition of Bone Meal.
