My Sweet Granadilla Vine Produced Lots Of Flower Buds, But Most Of Them Do Not Open Full And Shrivel. What Causes This And How Do

Question

I fix it? I have a sweet granadilla vine that has produced so many flower buds. Most of them will start opening and then just stop before they are fully open and start to shrivel. Eventually the drop to the ground. I am so keen to know what causes this problem and how I can fix it, because the vine still have lots of buds that have not started to open

This is typical of a few common problems.

The first thing that I would take a look at is your pH. Soil that is too acidic can lock out phosphorus and potassium. We are more concerned with phosphorus in this case.

That brings me to the next possible cause. Too much nitrogen. This will make the soil acidic, as well as lock out other nutrients, compounding onto the problem.

Poor soil nutrients, in general will usually cause other symptoms as well. I am not seeing much of that.
