Hi, I have a non fruiting kiwi plant approx 20years old approx 2m high against a 1m high party fence with a south facing wall approx 1m metre away, the question is what has caused the upper leaves to curl up and fall off virtually overnight, it is watered once a day on dry sunny days
Any advice would be gratefully received
I'd check the roots. Scrape away some soild, but by bit looking for larvae that might have chewed through the bark. If they do that all the way round (girdling), that can kill the plant. Vine weevil /other larvae can do that, even on woody plants. But the roots could also have been compromosed by fungal pathogens (look especially for black flattish strands like boot-laces - suggestive of honey fungus).
To be honest, I'm a but surprised by the leaves dropping off. Usually, physiological problems of this nature might cause the leaves to shrivel but stay attached. The dropping-off behaviour is facilitated by the process of abscission, which requires the plant to be in a fair state of health (as happens with deciduous trees in autumn).
So I'm not really sure what's going on; need more info. Do the leaves themselves exhibit any abnormalities, such as pustules, coatings, insects?
It will be non-fruiting because it produces male and female flowers on different plants. Yous is either a male, or it is a female without a male nearby.
Can you post a picture I live in Kiwi country normally its a mile a minute plant yours without harsh pruning sounds like a runt
ps there is now a male/female plant
Hi, Mike thanks for reply, the leaves do not see to exhbite any pustules, coatings, and no insects detected, I have attatatched 2 photos one on 10/07/14 first day noticed, and the 11/07/14, hope can clarify
Thanks for the pictures
I have not seen your plants symptoms before, your image contains your location and I see your are very far North,( I am on the French/Spanish frontier} have you had cold evenings/nights recently ?
PS If you wish to delete your pictures I will delete this reply and I hope, allow you to edit your posts
Probably overwatering, from what I can see. Not bugs or fungi as the primary cause (as I was hinting), but they'll move in as the roots rot from the excess water and lack of air. Note how the dead leaves are remaining attached, at least for a while (as I mentioned earlier).
Having said that, trace the affected twigs and branches back; see if they all come from one stem. If they do:
- check there is not a wire tie choking the stem at some point
- hope the other stems don't go the same way (tie-choking or overwatering)
Those Pelargoniums are not going to be best pleased with that dark (peaty?) wet soil either.
FYI, I have a Pelargonium here in my garden in Cyprus, that was unearthed for transplanting which never happened. It stood as a rootball and stems for two years, through five months of scorching summer heat and drought, without a drop of water, and although it is clearly not at its best, it still has flowers and leaves.
What do you think, Steve?
My thougths are its desiccation affecting recent young growth caused by cold, or strong wind breaking a shoot, its up in Newcastle well out of its norm with overwatering I would expect yellowing leaves
As for your Geranium Mike your lucky we have the Larvae of this South African imagrant to deal with
To me, the dead leaves look to have been of similar character to the remaining live ones, so I would imagine cold wind would have affected them both similarly. But a wind-broken branch - yes that's possible.
No mention of yellowing of the leaves, true. But I have seen root problems caused by overwatering kill stems sufficiently quickly that the leaves didn't get a chance to hint at the problem.
Let's see what oak has to say...
PS. Re Cacyreus marshalli...
Another cracking photo Steve!
We don't have it in Cyprus yet, but it has got as far as Malta.
lol its on its way
Seen at Christmas in a conservatory in the Dordogne lol
