i’ve got about 10 raspberry bushes in a fruit cage.

all growing healthily, just went out side and something has stripped one to its stem.

i’ve looked at others and can’t see anything lurking or even any signs of damage to them.

any ideas what may cause it?

I'm afraid I don't do fruit and veg so I need to leave this to someone else. However, a photo would help. Might be able to spot something that also attacks ornamentals. Have a look around for the huge caterpillar of the Emperor Moth. They feed on Blackberries, but years ago, I bred some on Raspberry leaves and they loved them. Just a wild stab in the dark and unlikely, but you never know.

Great to have some rain this week eh!

Very similar to myself with lots of box hedging, but I'd agree with [MENTION=259]Jack Straw[/MENTION] that it's decision time.

If I knew then what I know now, I wouldn't have gone with box, but it's probably taken me 5-7 years to get to what I now have with my box hedging. (And it does look great!).

If you decide to take the buggers on, I suspect it will be an ongoing battle, but I'm hoping that pheromone traps, renewed each year, together with a couple of sprays (insecticide or nematode) each year will keep them at bay.

Let us know what you decide to do :thumbsup:

I think I'm going to give it a go with your treatment recommendations. Mainly because I can't afford right now to rip it out and start again (appreciate the honesty, and advice though Jack!). So may as well give it a whirl. At least I now know what it is and if future outbreaks occur I can get to it before it takes over..

I grow Raspberries and I don't think that anything has ever gone and stripped a plant of mine. Slugs and snails are out, so very unusual.

Photos are a must so we can diagnose things easier.
Roses never do well in pots. Even when it rains a lot, pots still need watering, perhaps every day. We don't know how big the pot is, but regardless, the soil could be very dry.
Was there black spots on the leaves before they went yellow?
Photos please, and have a little dig of the soil to see if it's moist.

No black spot. Up until a week or so ago it was growing like a mad thing.

Vine Weavil - see if there are some small white grubs in the soil, eating the roots?

As Cheshire Cat suggests, it could be Wine Weevils amongst the roots. There's no bits taken out of the leaves which means it's nothing above ground.
Have you had a dig in the soil to see if the pot is really wet? How often do you water? Have you sprayed it over the top with anything? Have a look in the soil for white maggoty things (Wine Weevil grubs). Have you fed it lately?
I don't think it's a disease. I still think it might be due to drying out, especially when you say it was growing well up until recently. Of course, I could be totally wrong!

Anyone know what this is? Found in woodland in Kent a week or so ago. The leaves are quite broad like an orchids, green with black markings (you cn see some leaves in the first pic). I found two small isolated spots some miles apart with a few of these in land otherwise populated with bluebells.

I shall investigate tomorrow and report back.

Probably Early Purple Orchid.

Re the rose problem.
I don't think it's vine weevil damage, looks more to do with drying out. Roses really don't do particularly well in pots, especially after a couple of years. They tend to replace the soil with roots. Of course, I could be well off the mark and it's waterlogging, but that normally causes defoliation

They do like a nice dose of manure. Maybe the rose has used up all the nutrients it has and succumbed to an infection or old age ?

Gorgeous looking plant. Following up on JS’s answer, Rice Wood by Faversham seems a favourite location for photographing Bluebells, orchids and Wood Anemone.
