Rhododendron Mould?

Posted: 17/03/2012 at 23:39

Rhododendrons don't like being cut back hard, in spring it's ok to trim old and straggly stems. Also the black mould should gradually get washed off by the rain after you have treated the scale problem.

The plant has probably got scale insects look carefully on the under sides of the leaves above the black mould, the scales are usually seen along the center of the leaves and down the stems if you find them you will have use a spray to get rid of them.

Talkback: How to make a box ball

You can take box cuttings in August to September, about 3 to 4 inch stems dipped in some rooting powder or gel if you have any, into gritty compost. by early the next year you should be able to pot them up singly. It takes about two years to get plants the size to plant out .( cut the stems just under a leaf and remove the bottom few leaves or take heel cuttings, I usually do a few of both and just keep them in a unheated greenhouse and most take)

tomatoes and mould

You did not describe the mould you get on your plants. There are a few different moulds tomato plants can get, a grey mould (Botrytis) and tomato leaf mould which causes brown purplish patches on the under sides of the leaves and yellow patches on the top, both of these can be caused by damp conditions and not enough ventilation especially at night. You can also get a black sticky mould caused by pests such as white fly.

This can be caused by a lack of water in the previous summer when the buds are forming , if you need to water always try to use rain water.

Vine Weevil grubs and wild primrose

Posted: 06/03/2012 at 21:43

I have had problems with vine weevil in my greenhouse pot plants for the past few years, there are a couple of vine weevil killer water on drenches you can use (Not for use on edible plants) . There is also a safe nematode control available through mail order which can be used in the garden soil or in pots when the temperature starts to warm up , I going to try this solution this year as I am not too keen on using chemicals. I have never found the grubs in the garden soil only in pots with peat in them. 

Looking for evergreen climber

A few of ideas for you, there is a evergreen Honeysuckle also an evergreen jasmine, You will  need some trellis on your fence for support for these plants. A plant I have not grown before but gives year round interest is Hydrangea ( Seemanii) an evergreen with white flowers in summer.

I wouldn't give up on the hedge yet, wait until the weather warms up then give it a trim when you see new buds form. Good luck.

black spots

If the plant you describe is a red robin ( Photinia ), black spot quite a common problem, which can be caused by weather conditions or a fungus.Collect and dispose all fallen leaves, You can try a suitable fungicide in spring. I get this in my garden and it is something you have to put up with, some years the plant suffers much more than others.
