Oleanders won't be affecting at all. However, if they are doing well, then I suspect the conditions that suit them are a bit too hot and dry for the philadelphus. Tough though it is, it might have struggled for water at some point. It'll be fine once the weather changes,but chuck a bucket or two of water at it and see how it does. A bit late now as the leaves will be fading soon, anyway, but it won't do it any harm. A mulch next spring to conserve winter wet and provide a bit of food might be of use.


how to care for Cotoneaster Franchetii

You can nip them back now, if you want, the plant is tough enough. It's naturally a leggy thing when young, but will slow as you early summer prune to keep it in shape and as it ages.  Makes a nice neat hedge in time.  However, if you want it to flower and produce fruit, then I'm afraid you'll have to let it have its head a bit because pruning in summer will lose you flower and therefore berry, too. So, a tidy up in spring might let the plant flower and fruit and keep it in shape.

Let the stems blacken, which they will at the first frost, then remove the old growth and do the mulch thing (or lift the tubers and store them). If your neighbour's plants are surviving well with just a mulch for protection, then I'd go with that. No, the mulch can stay - it'll just rot down and become a nutrient release for the plants. However, don't rely on that for food. They will benefit from a top dressing of good compost in spring (not too rich, that can cause yellowing and weak growth) and a high potash feed when buds start to show.


Pyrocanthus dying ?

Look up pyracantha scab, from which I think your plant is suffering. Clean it all up, remove all fallen leaves and the fruit then hope. It may well come back ok in spring. Cold weather stops the fungus but next year it'll attack again, so good hygiene and keeping it well fed and watered will help. 


Whats up with my blueberries

They really do need acidic conditions.  If your soil is at all alkaline, then I'd grow them in pots, in ericaceous compost and top dress them each year with leaf mold, keeping them well watered.  Have you deciduous or evergreen varieties?  Sunshine Blue is a good evergreen one and Bluecrop one of the best deciduous varieties.


Red spots on hydrangea leaves

Posted: 27/08/2017 at 18:59

It's a tough time of year, summer, especially for hydrangeas. Give them a soaking and wait to see what any new growth looks like. If it emerges fresh and green (and there's still time for a bit to be made), then the plants will be fine.   The spotting is fungal, the result of humid conditions and dryness at the roots can cause the plant to suffer more. 


What's eating my salvias?

Posted: 27/08/2017 at 18:55

The yellowing is caused by the damage (nutrients can't travel through the damaged tissue) and I usually suspect tiny slugs. They're my first port of call. However, I'd check for tiny caterpillars in the leaf bud stage, because it looks as though the leaves are emerging with the damage. Try a mild spray, something organic - garlic?


Unknown plant/weed?

Posted: 27/08/2017 at 18:50

Hypericum androsaemum, "Tutsan". If you pull off some of the leaves and let them dry they smell curry like. British native, pretty in flower and useful for a shady spot. Look up its medicinal and other uses. 


Yellow plum/damson leaves

Posted: 27/08/2017 at 18:06

I think it's just that they're new in, they had a long dry spring and have struggled a bit since. Were they bare root?  Flowering takes a lot out of a tree (fruiting even more).  They'll be fine, I expect, with time.  Allow them a season to establish.

Not aubrieta, is it?  Tends to be mauve in nature, but obviously,pinks, darker blues and richer hues occur
