..on the balcony

Hi everybody,

meanwhile the most of my passion flowers have been transferred to my balcony (southside). During the time inside my flat they looked very good but some of them change their appearance within some days when getting outside. The leaves became yellow spots and shriveled leaves. Here an example on my Passiflora Guglielmo betto and Sapphire.

My other Passiflora-friends told me it lookes like a virus infection. What do you believe ? Is it possible that inside the flat the conditions are O.K. and they don´t show any virus-effect and outside caused by wind, sunradiation and rain the conditions for the plants are harder and so the virus has better conditions ? Are other explanations for the shriveled leaves and yellow spots ? It´s hard for me to believe that they are virus-infected. If it is a virus, have only my plants a virus or is it known that Passiflora Sapphire or Guglielmo Betto are infected (like xbelotii or Incense) ?

Whta can I do ? I don´t like to tranfer them back to my flat during the summer. Some of the red-flowering plants and my decalobas are inside because I believe that they like it more than outside.

Thank you for help !

Just heat stress it looks like. If its just showing up a few days after being put outside. This is normal for some plants when they go from well shaded indoors to the sunny outdoors . Think of it as a sun burn. If ifs being kept watered right then in a few days you should see that the new growth wont be burnt like that. It Could also just mean you should switch them to a less direct sun spot. I do not believe this is a virus, though Im sure someone more skilled in spotting a virus might comment later. And to your question about known infected passiflora, I have both, Guglielmo betto and sapphire and nether are infected so that should clear that part up, as im positive I dont have the only non infected ones. Any more questions feel free to ask!

Hi nickisking,

thank you for your information. Some new leaves of Guglielmo betto didn´t show this effect, I hope the stress is over. The Sapphire still produce these spotted leaves and also some flowers remain half-opened . Maybe these both plants didn´t like southsided balconies . I will observe and post again, whats happened. I´m happy that I have more than these two .

Do you know, which passiflora are more "heat resistant" and accept direct sun ? For example my Passiflora Cearulea "Constance Eliott" and Incarnata didn´t show such phenomenon.

Bye

All my cearulea hybrids do amazing under the sun. of all the plants I own. All of my cearulea, and edulis do best for me in the transition from indoors to outdoors. Of all my plants outside the only ones that showed heat/sun strees were, Inspiration, tatei, and my Decaisneana. With my best outside plants (in pots) being, passiflora byron beauty. which even in a pot still manages to shoot up 3 feet ahead of the rest and has been blooming sense day one being outside. It never shows sun stress for me. I find tetriploids are very tough. If your flowers are only opening half way with these spots and stuff try giving it good fertilizer. I know myles has shown photos of passiflora that look extremely bad with spots but with the right fertz and care he is able to make the spots dissapear within a few weeks. I pretty sure his posts about it were to show that with the right fertz u can help an infected(if that is the case) passiflora to better health. Im sure he will correct me if im wrong. but that to might be something to look into. but be carefull with this as to much could just lead to more spots.
