passionfruit (forum)

Paula starts with ...
My purple passion fruit vine produces a huge crop each year but only of few seem to turn purple. Most are the size of tennis balls,but if I leave them on the vine too long, they get spots or start to rot. the still taste great but how do i get them to colour ? Thanks Paula

What kind of "purple" passionfruit are they Paula? Does the vine have a name? They don't look like Nellie Kellie purples...not with the little silver dots on them?

Is it a Panama Red? They don't need to go dark coloured to taste good - sometimes if the vine/fruit is not getting all day sun/or the fruit are buried in the canopy....then they can be quite pale.

Here are 3 windfall fruit I just ducked out and grabbed off the ground...They all taste great...one is barely pink let alone red..?!
It's ripened inside the canopy (also judging by it's drop location)

I don't eat the skin so I am not worried about it's colour.. ;-) It's what's inside that counts...

(ps - note the silver speckling too - this is my Panama Red fruit)

Amanda, do you know if they will produce down south? The Big red I have now covers the trellis, but not one flower let alone fruit, to date!

I don't know SG...I have asked if anyone growing Panamas in Perth - but no responses. Not sure how they will handle winter down there...

How old is your Big Red now? Pretty vigorous aren't they! Mine has broken the thick fencing wire that runs across the top of my orchard fence...

It hasn't really flowered much this season...neither have my panamas...I don't know why...my sunshine special is loaded with flowers again (2nd or 3rd time this summer) Makes no sense to me sometimes (rolls eyes!)

It went through last winter ( its first) with little more than yellowing of leaves which the black seedling also had! Of course that one went on to produce nearly 30 nice fruit! Some fell early before completely purple, but most were just right!

Do u think the leaves were yellow cos of the cold SG? Or a nutrient deficiency problem? (what's the soil pH around them?)

The Big Red may not flower until next summer SG..it sounds a bit young yet.

What a coincidence! I just visited a mate with a young Panama Red that had only one flower this summer, & he pronounced that next year it will have heaps! He also had a young purple that has produced heaps this season so I obviously need a little patience!

Passionfruit not ripening says...
I pick my panama reds when they just start to turn a pale purple colour. Unfortunately, recently, they are not changing colour at all. They seem to grow to a lovely size, look great, and then they turn a lighter colour and go rubbery and crinckle. Have you experienced this problem? I don't know what to do.

Water - lots more PNR...what do they look like inside at this stage? Are there many seeds? Are they completely dry?
Grab one of those $10 moisture meters from Bunnings if u are not sure - they are very helpful..

The $10 moisture meters from bunnings are most often faulty and inaccurate. Better to get the $12 mm's from mitre 10

Thanks Amanda, I'll try more water. We have just come through a period of lots of rain over here in Qld, so I thought it may not be water, but maybe it drains away very quickly. I'll have a look inside one and get back to you with info on your other questions.

Possibly PNR - it's hard to say as I am not there :) We can only go by the info that is given here...?
Not all things are equal sometimes, Eg: my vine against a wall and the leeward side of the house - so even when we get heavy rain the vine gets very little. My vines take about 60L of water every two days when in full crop, in summer...I feed them a low nitrogen fert to sustain the crop - if - it's looking 'hungry', or starting to drop fruit blah blah.. ;-)

It's best to start with the usual culprits first - this includes the leaves also...eg: are they healthy? spotted, marked, dropping? etc.

PNR,Amanda I have seen that happen to passionfruit before and it looks different to me from a lack of water.Woody virus deforms them in a different way and they get hard and a second fungal/viral condition deforms their equator giving them a waist.The spotting sounds like a fungal affliction a bit like anthracnose that is common around here in the wet season and doesn't seem to ruin them unless the condition keeps getting worse.The soft wrinkly one could also be a pathogen even if foliage looks alright and roots seem firm and strong.I look at DPI 'troubleshooting' sites for growers at times for sick plants.P,K and micronutrients may help if the plants have not been fertlised for a while.

Maybe u right Mike - the only thing I have seen in my travels that looks anything like this fruit is phytophthora....(but that looks a bit more drastic than this fruit) but it could be early days with black/brown spot you think?

Agreed tho' - woodiness virus doesn't look like this.
PNR doesn't mention any spotting or other pathology. She should use an antifungal also u think?

Phytophthora and other root rots would make leaves wilt and yellow and it could look like it needs watering.Fruit I expect would abcise early.I would try phosphanate anti-rot which is a tonic,for phytophthora.
For other suspected fungal problems I would mix mancozeb and copper-oxy or go to a passionfuit help site.I don't know why the vine would hang on to badly damaged fruit, like it doesn't get a trigger to produce abcisic acid.

Brendan it is better to put borax and potash on together as they are antogonistic.All passionfruit could probably use more potash and nutrient problems often allow a pathogen to take hold.I presume you're talking about the wrinkled one Brendan.Oh yeah the garlic is all up and flourishing.

Yes Mike, that wrinkled passionfruit looks like it's lacking boron for sure.

How many garlics have you got up Mike? I've got 'only' 174 up :-) Even the Purple Monaro is powering! If it works, I'll send you some next year.

Ok boron.I use borax and micros and I had one that pulled that wrinkle fruit stunt.My soils must be very low in boron.
The garlics were sprouting in the fridge and almost jumping out of my hand to get at the soil.I have maybe 25 of them booming like yours by the sound of it.Purple manaro sounds like a claasic.I wish I could get those tropoical asian pungent types like you see in SE Asian markets.

I'm working on it but they don't seed they are vegetative.Nearly all Allium seeds are permitted but not corms.Your eyes would pop if you saw the Chang Mai markets selections stacked on the tables.I would always share with my chums if something good were thrust upon me.Arkansas travellers and thai pinks are popping up and tropicals are planted out.

Passionfruit not ripening says...
Amanda, I opened up a crinckled passionfruit and it has lots of seeds, not edible though, and doesn't look dry. This crinckleing can occur very early in the fruit growth or the fruit can grow to a very large size, then crinckle. They will drop off after crinckling...I usually pull them off as soon as I know they are going to crinckle so they don't use up any more of the vine's resources. I'll get a photo of the next one for you. I have been reading the forum and sounds like I should try boron, never used yet. It's funny that the first vine I planted in this same location performed extremely well, then subsequent vines have just not done as well. Meant to add that the vine and leaves look very healthy. Flowering looks great. Ants polinating.

It would be good to see a couple more fruit (big and small) and a more close up shot....I like to learn as much as possible too. The one fruit u have here looks almost like it's "collapsing" rather than wrinkling....do they all look like this?

Boron certainly worth a try as Brendan mentions - be careful tho...only a small amount is needed and usually only once...too much is toxic.

I'd be tempted to give it a bag of nice cow poo too.

I found a pic - but this fruit much further gone than yours...not very pretty in comparison either. (ps - this is fungal..and starts with those spots..)

Help, Does anyone have an answer and a solution here.
Have three types of Passionfruit, as the month of May is here and almost into June, My vines are "loaded" with green fruit, they don't want to ripen.Q: wonder if this is normal for this time of the year (so late), and is it a lack of something that sends a signal for them to start ripening???
Thanks. tigermothpilot@hotmail.com

That's fairly mormal for the southern states. Don't worry, they will hang on all winter and ripen when it warms up again.

Cas Allan says...
My vine is two years old but has been in the ground only this spring and summer. It is a panama red and because of the very late summer we're still having in May it is laden with fruit. It grows on a north/south fence and the western side of the fence is open to the elements because we live at the top of a hill so our neighbours are down a steep hill from our yard. My fruit has been turning red slowly as they should but today I found one shrivelled fruit on the ground. It is very pale green with the reddish spots this type of fruit goes through before it becomes all red. This is the first time I've seen a fruit like this. It grows next to a well fed grapefruit tree so I don't think it is lacking for food or water. I saw someone suggest Boron? What does Boron do for a vine? This is the only one so perhaps the stem was damaged?

Kevin, I have a feeling some of mine won't ripen before winter either. I've netted mine today so the birds won't get into them. I threw a tree netting over the vine and the wooden fence and attached it with some shade cloth brads.
