Bye bye Clematis Cassis

Posted: 15/07/2012 at 21:17

Have the stems been thoroughly nibbled by slugs? If so, treat it the same as clematic wilt and protect the newly emerging stems. Or are the stems just fragile and might they have suffered damage from strong winds or an accidental blow? 

Deadheading RhodedendonDead

Posted: 15/07/2012 at 21:07

This is what the ASmerican Rhododendrom Society says:

'It is desirable, with the large flowered rhododendrons, to remove the withered flower clusters after the blooming season.  This is fairly easily done as the central axis of the cluster, usually called a truss, will break free from the plant with a quick snap of the thumb pushing on the side, or can be cut off with a hand pruner.  With the smaller flowered rhododendrons and azaleas, dead-heading is labor intensive and and generally is not required.

Dead-heading is usually done to make the bush look more attractive, to reduce the prevalence of fungus and to prevent a heavy set of seed.  If it is not possible to remove the old flowers, it is usually not too detrimental, but flowering the next year may be reduced.'

This should be done when the petals fall, depending on the variety of rhodo you have. Now is surely better than not at all.

Gardeners World - not back for 4 weeks!

that's what I hoped for! I was incensed at the word limit and the patronising tone of the BBC's compaints procedure - and the fact that you could not complain about the non-appearance of a programme, only about one that took place. The cancellation of a programme warrants only a 'comment'.  Thanks for writing!

Some are hardier than others but, like many other people, I have clumps in my garden here in the milder south west that have lasted for years and root easily from cuttings. They get woody if they are not cut back hard every year. I do this in spring. They can overwhelm other plants if they are not cut back because they spread a lot.

Also car boot sales and those houses where people sell a few plants at the gate. If you find a WI market where the plants are cheap, please let me know!

It likes shelter from winds and it doesn't like being waterlogged but needs good drainage. Could it be the wet, windy weather again?

mosquitos breeding in the rainwater butt

Posted: 10/07/2012 at 06:17

You can also add polystyrene beads, which help prevent the mosquito laying eggs in the water. If the water is used regularly, so that the water is constantly changed, there isn't much problem because mosquitoes like stagnant water, but in wet weather such as we are having at the moment, the water in the butt can be undisturbed for quite a time. So it might be an idea to empty the butt and start again. 

What is your kind of garden?

All glorious gardens.(I have looked at your on another thread, Lilylouise, and you are a much better gardener than me. Yours is one of those perfectly cared for gardens.) I hope we see lots more.

Root destroying insects

Posted: 09/07/2012 at 21:34

I agree that the gnats are likely to be attracted by the decomposing vegetation of your damaged plants. Have you tried going through the roots and looking for grubs? Sorry if this seems to be treating you like an idiot..

Root destroying insects

Posted: 09/07/2012 at 17:46

Is it the insects eating the roots or is it their grubs? A common cause of root destruction is vine weevils. which look like little black beetles. Their curved, whiteish grubs do the damage but you may see the adults, which only eat the uppper part of the plant. You can buy stuff like Provado to kill the grubs and you have to pick off the adults by hand, preferably at night. Another common cause of root destruction can be ants, as sotongeoff has pointed out, but I'm sure you'd haved recognised them.

Vine weevils are a horrible pest and you sometimes have to  be quite persistent to get rid of them. They particularly like the soil in pots, because it is easy for them to dig down in it to lay their eggs. Hope this helps.
