Passion flower does not bloom: possible causes and solutions
Passionflower flower fails to bloom: The wrong location
Passionflower thrives best in sunny and warm locations. However, it cannot tolerate heat, rain and wind well. During prolonged periods of heat, you should protect the flower from the strong midday sun . However, make sure that the flower is in a sunny position for at least 6 hours a day. Too little sun can also have a very negative effect on flower formation: in shady and semi-shady locations, the exotic will not form flowers at all.
Young plants need more time for flower formation
You have received a flowering passion flower in a container as a gift, but now it no longer wants to bloom? Then you can rule out old age as a possible cause. After all, plants that are currently blooming should still be able to form new flowers. Young plants that were pre-pulled last year, on the other hand, need time to form flowers. Climbing plants need between three and four years to develop their root system. Old plants should also have no problems with flower formation, as long as they form new shoots, nothing stands in the way of a magnificent bloom.
Passionflower diseases that affect flowering
Problem: If the plant is neither too young, nor too old, then you should look for another reason why flower formation is failing. Burn spot disease or anthracnose is often to blame. Fusarium oxysporum is the cause of a fungal disease (Fusarium wilt) that can delay flowering. Mosaic virus has a similar effect.
Possible solution: take a photo or describe the disease pattern to the garden center or nursery.
Use nutrient-poor potting soil or overfertilize the passionflower.
Problem Nutrient Deficiency: Passionflower is not a heavy feeder, yet it needs regular fertilizer applications when grown as a container plant.
Possible solution: water the plant from below so that it does not wash away the valuable nutrients with the water. Place the passionflower in a location protected from rain.
Problem over-fertilization: If your plant has few flowers , but has formed a lot of leaves, then overfertilization could be the reason for the lack of flowering. The wrong fertilizer can also be to blame. Nitrogen fertilizers are often the reason for the lack of flowers.
Passionflower does not bloom: Too small tub
Problem: If the passion flower forms few small flowers, it could be due to the size of the tub. If the exotic has no room in the tub for its roots, then you should repot it.
Possible solution: repotting and thinning. Especially if you grow the passion flower as a climbing plant in the tub, you should cut off old shoots at the start of the garden season (and during the flowering period).
When the houseplant is attacked by pests such as thunderbugs and aphids.
Problem: If the potted plant has to brave rain outside, then it becomes weakened and susceptible to pests such as aphids and thunderbugs. Infestations can interfere with flower formation.
Possible solution: you should regularly check the plant for pests and then act quickly at the first sign of an infestation.
Water passionflower properly
Problem: Passionflower needs regular watering, but too much of a good thing can have negative effects. It is not a problem if you overwater the flower once or twice. However, you should regulate the amount of water really well and work sand into the potting soil to prevent waterlogging.
Possible solution: the good drainage is an absolute must. If there is too much water and rot, only repotting will help. Place the plant away from the rain.
Passionflower does not bloom, how can I propagate the plant?
You can easily propagate the passion flower by cuttings. Even if the flower does not form flowers. The most important thing is that it is not diseased and is not attacked by pests. You will need several 15 to 20 cm long branches with leaves. Remove all the leaves except for 2 to 3, which are at the very top of the branches. Mix potting soil with compost and pour the substrate into growing pots. Then put the cuttings in the pots and place them on an off-sun windowsill. You can cover the pot with a plastic bag for the first few days. Remove the bag in the morning and evening and ventilate the plant.
