I am new to gardening and I have used well rotted manure from the garden centre in my beds and I feed with miracle grow. However I think something is wrong. I don't get many flowers and none at all on some of my shrubs which are meant to have flowers . A long established viburnum gets lots of dry dead yellow leaves which fall off even now in June . I don't think it looks like any of the disease I can find pictures of in books or on the internet. My choisa sundance gets white leaves and no flowers, my hydrangeas get white and pale yellow leaves . The soil ph is neutral. Could I have a soil deficiency and how can I find out? Thank you
The RHS offers a soil analysis service. £30 for non members.

Do you have dry soil? And are these plants in the sun?
Sundance doesn't really like too sunny a spot.......the yellow leaves become parched. The hydrangea too but more so as this likes plenty f moisture.
When you use your manure do you leave a space around the base of the stem? You should. I don't like using manure too much in the summer.....it takes nitrogen from the soil if it's too fresh. Better to use it in autumn and winter in my opinion
I agree with Verdun - more information about the garden would be helpful - maybe some pictures too?
I believe there's been a problem with some manure bought from garden centres. It may have mixed with straw that had been treated with weed killer when growing. It was suggested to try to sow some quick growing seeds such as lettuce to see if they germinate in the manure.
Lynne a couple of us answered your other post on this subject asking the same- pix are very helpful along with as much info as possible about site etc.
Pam that's very interesting re the manure. Not helpful if you've used it all over your garden and it's potentially got weedkiller in it.
Just looked on the RHS website about contaminated manure. Apparently some pastures are treated with aminopyralid which does no harm to the horses but passes through them into the manure.
Lynne - is this a new problem this season, or has it happened in previous years too?
This season is an odd one. Leaf infections, slow growth, distorted growth, yellowing leaves, white leaves, red leaves, etc etc earlier in the season but now resolving themselves. Although plants' "DNA" tells them to grow the cold spring has confused them.....Me thinks!
