Unknown plant

Posted: 07/07/2014 at 18:55

The wild one shown (Oenothera biennis) can be a bit invasive but there are some rather nice cultivated forms called Oenothera Odorata which have a fantastic scent and larger more refined flowers.

 

Why do perennials die?

Posted: 07/07/2014 at 18:50

Many perennials are short lived - geums and many salvias among them.  Neither live for more than about 5 years on my clay soil. 

Little Black Beetles

Likely pollen beetles which are harmless but annoying.  They only eat pollen, so if you have damage to the lilies, look elsewhere for the culprit, which will very likely be red lily beetle larvae.

Sick Rose

I'd agree with Sue.  The lichen is merely an indicator of their age and is not harmful in any way.  It does show you have excellent air quality though.

tomatoes

Posted: 06/07/2014 at 21:43

I have about 30 plants, some in an unheated glass GH and some in a polytunnel and all are looking very healthy and have unripe fruit, but they're all a bit behind due to a few late cold snaps while they were young, despite them being started about a month earlier than I usually do.  There's a lot to be said for waiting a bit longer before sowing tomatoes, even if you do have a propagator, unless you have a heated greenhouse or conservatory etc to keep them in while they are young.

leaf curl on fruit tree

Posted: 06/07/2014 at 21:30

If they have gone I wouldn't bother removing the distorted leaves as they aren't diseased as such, just distorted and will still be supplying goodness to the fruit.  Do think about using an organic winter fruit tree wash to try and stop them doing the same thing next year though.  The aphid eggs overwinter on the tree and start on the buds as they open.

Glass cutter

I agree with phlox - old glass is a PITA to cut due to stresses that build up over time.  Old horticultural glass is dangerous stuff to handle, too, so do take great care KEF.

leaf curl on fruit tree

Rich, check with a magnifying glass as 'plum leaf curl aphids' are much smaller than ordinary ones and difficult to see for most people.  I think that is why buddyboy asked, as the symptoms look exactly like your trees show. 

The RHS advice on plum problems is here:

Silver Birch dropping yellow/black spotted leaves

Posted: 06/07/2014 at 17:23

Yes, many birches near me get this and don't seem any the worse for it.  Some other types of tree come in to leaf late to avoid pests and diseases while birches seem to favour dropping affected leaves and growing new ones.  I'm sure it will[ be fine and the majority of plant diseases are specific to just a few related species so It's unlikely to affect anything else in the vicinity.  The chances are it was a fungal infection carried by aphids.
