Passion fruit looking yellow

Hi all,

I transplanted two passionfruit vines into my south facing front yard against a trellis. Since I planted them, the foliage has slightly yellowed, and I have not seen much growth since it was still in a pot (about 5 weeks).

I did use 2 cf of steer manure mixed with native soil into the planting hole, and I water deeply twice a week. I also used about two cups of Gypsum to help break up the clay soil.

Please see picture below of a typical leaf.

Any ideas? Is the soil salinity now too high?

You mention clay soil, it could be poor drainage, with water sitting around the roots.

RE: Passion fruit looking yellow

Update: the leaves are getting more yellow, but strangely enough, I am still getting passion flowers and the vines are still growing, but very slowly.

hmm, it could be drainage... but it is planted on an 8" mound...and my bananas in the same planter seem to be doing fine.

Do passionfuits like drier soil?

RE: Passion fruit looking yellow

Did you check the underside leaves for spider mites?

RE: Passion fruit looking yellow

Hmm... I will check. I did have a spider mite problem with the Mandarin.

Since then, I have already sprayed both with Neem, but it has only been 3 weeks. Time will tell if the new foliage is healthier.

RE: Passion fruit looking yellow

Passion fruit usually don't like the neem or any other oil based sprays too much. It can clog the leaves underside and they will die off.
