Title: Roses - leaves turning brown and dropping
Post by: boogaloo on March 05, 2012, 14:21

Hi

Wonder if anyone can help. I've got a beautiful climbing rose in a huge pot outside my front door - planted last year. We're actually due to be getting some paving slabs lifted so that we can establish it in the ground, but it's grew like a rocket last year, and the pot's a whopper. It was perfectly healthy. In the last week, though, the leaves have been turning a rusty brown (i'm sure it's not actually leaf rust - just dying) and falling. The problem started near the roots, and it's slowly shedding leaves upwards.

The leaves turn brown, droop, and fall.

The soils good quality, it's well fertilised (i popped some blood fish and bone in a few weeks ago, and a smidge of toprose), drainage is good too.

I've checked the underside of the leaves, and I can't see any signs of insects or critters. Any theories? We were due to move the plant in the next few weeks, but I daren't now that it's looking so fragile.

A couple of photos if that helps... I should also mention, it's on a NW facing wall that gets good evening sun, but nothing in the early part of the day. Does that make a difference? Was fine last summer, but I guess there was more light around then...

Mine has dropped all it's leaves since the last cold snap, and the buds are now fattening for the new growth. Your plant sounds the same, I shouldn't worry

It could either be the recent cold snap as Mum says - or else a nutrient deficiency - both of which are best sorted by the application of a compound fertiliser, which you've already done.

Thanks folks, I'll hang on in there then. Cheers for the advice.

It could be frost damage, or have you had any strong winds there recently, because as it is against a wall, the wind would "bounce" against the wall and back onto the rose.
