The tall ones in the first pic are delphiniums, Alan.  Just about to flower by the looks of it.

I'm not sure about the 2nd one - possibly daylilies (Hemerocallis) as the leaves of those are around for months before the flowers start appearing and they are quite rampant growers.

5mm worms in potted plants.

They do sound like fungus gnat larvae to me.  Those are pretty harmless except to very small seedlings.  To keep them down, use fine grit to cover the compost and water only from the bottom as the gnats (small flies) can't then lay their eggs on the surface of wet compost which is how they proliferate. 

How to stop blue caterpiller eating my purple/brown leaf plant

I don't know what the plant is but the caterpillar-like thing in the 2nd image is a sawfly larva.  Those cause much more damage and strip plants vey quickly.  A truly organic control is to inspect the plant every day and pick them off by hand but if that's not practical, look for a spray containing Pyrethrum which is considered organic as it is extracted from plants of the chrysanthemum family.

new decked raised bed

Best to rough-dig it Joe, which will help with the drainage then fill the raised part with a mixture of topsoil and compost, adding some well-rotted manure (unless you're growing carrots/parsnips in which case skip adding the manure.)  An ideal mix for a raised bed is about 60% topsoil, 30% compost, 10% manure.)

A week of rain = jungle garden!

No problem nut, so we just call them wildlife gardens and be done with it!

I must admit it looks very healthy and is a treat for the eyes.  Maybe I'll just throw all the GH plants on the compost heap instead - a lot less work!

A week of rain = jungle garden!

Posted: 31/05/2014 at 14:18

Hi all,  Just wondering who else has ventured outside this morning to discover a veritable jungle has developed in their garden over the last week?  It has rained more or less constantly here for the last week and was just too sodden to attempt any serious planting when I got home from work each day so, apart from a bit of weeding (as those were easy to pull from the wet soil) I it has been left to it's own devices..  I have a GH full of plants which are now screaming to be put into the borders etc but due to the rapid growth in the last week, you've guessed it,  there isn't any room!  Looks like a fair few sacrifices will have to be made.

I've decided to dig up and replace every bluebell (all now crosses anyway) and Welsh poppy I see to make a start.

At least at the end of the day I'll be able to re-fill the compost heaps make a few gallons of Comfrey liquid feed (that has grown from 1ft to 4ft!)

To be honest, this happens every year so I don't really know why I'm still surprised when it happens!

Plum leaf full of holes

Posted: 31/05/2014 at 13:07

Have a look at the RHS advice for Laurel leaf problems, Glenda:

It sounds like one of the bacterial shot hole diseases.  Lots of wet weather is the primary cause allowing these diseases to take hold.

As for your fruit trees, most pests and diseases are specific to each type of fruit and don't normally affect other types of tree.  The cold weather in Winter usually kills many overwintering pests but we didn't really have any significant periods of sub-zero temperatures this year so there is more damage evident than usual.  Feeding your trees is one of the best things you can do to help them cope and hope for a good freeze next Winter.

hibiscus or rose of sharon

Posted: 31/05/2014 at 12:57

I'd give it a bit longer as Hibiscus can be one of the slowest plants to leaf-up.  I had two identical ones delivered early this year which went into the cold GH.  One began sprouting leaves in March, but the other remained dormant until mid-May.  It is getting a bit late though.

Brown spots on tomato leaves

Posted: 30/05/2014 at 23:01

Regardless of which disease is present, I have found the best way to deal with tomato leaf problems is to remove any affected leaves and burn them or throw them in the household rubbish bin - never put them in a compost bin.  I've even managed to keep plants affected with late blight going this way, although they did look very, very sorry for themselves!

Black Bryony would be my guess too.  They can put on an amazing show with the berries later in the year.
