Pests, Diseases and Cures

The leaves on an established rose plant have started to turn brown. Does anybody have any ideas what causes this and what I should do about it? about it?

I haven't got a clue Pete. I've never felt the need to test the soil in any of the gardens I've had.

Its not seen a frost Pete, its been in Kent beside the sea, i'm going with its had a very sheltered upbringing in a Dutch poly tunnel and being bought was just too much for it, poor thing. I will find somewhere for it to rest, drop its leaves and hopefully enjoy a shaded summer.

I wonder if that would keep slugs and snails away from all seedlings?

Good evening yes I have four Hebe's and they have come through OK and they are green ones

One of my two Colquhounias is now deceased; curiously the more sheltered one is deceased' I suspect this was more the drought than the cold.

I'd have to chop down about 70 trees! I keep the grass cut low in most areas as it's the only way I can physically cope with it. The only area I leave uncut is the wild flower area, about 3,500sq ft, that doesn't get cut between November and late June. The wild flowers are all self seeded...

Thanks for all the advice everyone!

cheap and almost bomb proof and fast growing its not surprising they used so often, you can get them looking good but they'll never look quite as good as loads of other hedges

Gunnera manicata are a bog garden, pool marginal plant and they get huge; seriously huge. See here Gunnera manicata | giant rhubarb Bogs/RHS Gardening and Gunnera I've tried both G magellenica and G prorepens, both small species; they lasted a couple of years here in Devon and then dry summers...

I dont really know how they do it, but the plants on sale often really dont look capable of growing the amount of fruit they have on them. I know most are grafted and some are not, I get the feeling that they are grown with a free rootrun and then potted up a few weeks prior for sale complete...

A basic principle when there has been a very hard, prolonged cold spell and there is damage to plants is to wait a few months to see how things recover. A lot of plants/shrubs/hedges are remarkably resilient.

It looks like mould to me, maybe you wet the leaves too much.

Many thanks for your help folks. As we just grow flowers & shrubs at home I'll wait until compost is rotted down & use on flower beds as suggested.

Again I so appreciate the replies. I will take it out carefully and replace the compost. I will stand it also on some pebbles. Water more and be cognisant of any munchers. I’ll be back with a picture in a month or so.

Grandma used to fill her bath and place all her houseplants to submerge them over night. She said they couldn't hold their noses for that long !

It's closely related to Neem, no? I tried a decoction of leaves and seeds from my Melia tree on the woolly scale rampaging through my citrus trees. It did seem to help, but like most treatments it needs a regular follow-up until the life-cycle is wiped out.

Not sure but it could be sooty mould from an earlier aphid attack. Aphids are often the carriers of viruses.

Thanks again for all the input. I will hold off till the new growth starts in spring.

Thank you @JWK for your speedy response. Its conforting to know it may come back OK and it isn't just us. We have spotted others doing the same here. Facing the loss of two prunes trees in the new year so was dreading the prospect of a bald garden, not that baldness is itself a bad thing, she...
