I want to share with you tips and strategies that assure you that the passion flower abortion problem will go away forever.
Before I share those tips…
Let’s start by knowing what causes flowers to abort.
By having that knowledge, on what causes flower drop in passion, you can develop a checklist that will enable you avoid them.
Top 6 Causes of Flower Abortion in Passion Fruits.
- Plant Disease.
Fungal diseases like Fusarium wilt, Phytopthora blight, Septoria spot can cause flower drop in passion fruit.
These diseases cause flower abortion by stopping, or restricting the movement of nutrients and water through the passion plant.
“How do these diseases do that?”
You may ask.
As the diseases grow on the plant parts, they enter the pholem and Xlem vessels, thus blocking them.
This vessels can no longer transport food or water to the various plant parts.
When the passion plant can no longer receive water and nutrition, the net result is flower abortion.
- Pest attack.
The most dangerous pests to a passion farmer are thrips.
They are responsible for 90% of all flower drop cases in passion fruit.
What makes them so dangerous is their minute size coupled with their feeding habits.
Their size makes them so difficult to notice, leading to delays in controlling them.
As hide inside the flowers, they puncture and injure the flower parts like the stigma, and anthers.
If the flowers are extensively injured, they can’t pollinate thus can’t form fruit.
Consequently, the passion plants will drop the injured flowers.
Thrips are not the only pest that cause flower drop.
Aphids, broad mites and yellow-black spotted beetle can also cause flower abortion after blooming.

- Nutrient deficiency.
During flowering, nutrients like Potassium, Boron and Zinc are ABSOLUTELY essential.
These minerals are required in large amounts in flower budding, fruit formation and final fruit sweetness.
When these nutrients are in short supply or lacking, the plant will have no otherwise but to drop the flowers.
- Water stress,
Like nutrients, water is absolutely essential.
Without it, the passion plants will abort flowers so as to maintain few fruits to maturity.
- Unfavourable weather
Too much rain, sun, or frosty nights, will lead to flower abortion in passion fruit.
- Lack of Pollination
When pollination does not take place, flower drop will take place.

During transplanting, fill the transplanting hole with lots of manure and organic matter.
As the plant grows, provide a balanced nutrition by using compound fertilizers like NPK.
When the plants approach flowering, and fruiting, spray them with foliar fertilizers containing potassium, boron, zinc, copper, every 2 weeks so that the plants get all the nutrients they require.

Thanks for the information its soon helpful,my question is I have planted passion fruits in a greenhouse,can it provide ideal conditions or it may be the cause of flower abortion
Hi Wachira. A greenhouse is not the ideal environment for passion plants. Why?
First it has to do with the nature of growth of passion fruit.
This plant produces a lot of vines.
These vines take a lot of space hence compromising the economic returns of the greenhouse.
That said, if you’ve already grown them and they are an advanced age don’t uproot them.
Let them act as a research project for the passion fruit industry.
