Potting on perennials?

Posted: 28/07/2012 at 12:49

I am just doing the perennials I grew from seed this Spring, but I would not do it much after the end of August. Once the plant has lost its top growth then all root activity stops as well and you would end up with a lot of empty soil round the outside of the pot. This could lead to trouble with sourness etc.

Are you sure of your diagnosis? They are more often found in Glasshouses than outdoors in Britain, except in the very mildest of areas.

Not well up on trees to be honest. but the trunk certainly is not a Viburnum

confued plant ????

And then you only have to wait about 5 years for it to produce fruit, 99.9% chance it will be a Crab apple too and if allowed to grow on could make a 25 feet plus tree eventually.

Yes, Viburnums are sometime grafted, but not onto Silver birch. Viburnums are grafted onto Viburnums, often V tinus. Birch is in a genus of its own, Betulaceae and Viburnums are in Caprifoliaceae, along with things like Honeysuckles, Abelia and Diervilla. They are just not compatible in any way.  The Silver birch which grew from your can only have been a seedling.

Viburnums are not grafted onto Silver Birch trees, so what you grew originally was a seedling in the compost.

Viburnum macrocephalum is not normally grafted on to anything, it grows well on its own roots.

If you need to then treat  it liie a half ripe cutting.

You can buy White beetroot seeds. Have grown them, but find them far too sweet for our taste.

Sharp sand drainage properties

Posted: 25/07/2012 at 10:50


Our soil is silt over a sand substrate and even after all the rain we have had, the soil is now beginning to become very dry after only a week or so of no rain.

As said grain size and shape determine the ability (if that is the right word) of sand to allow water to pass through.

Deutzia dilemma

Bit worried about the slow growth of Frank'sDeutzia. All of ours grow 3 to 4 feet a year after flowering is over and need a trim to keep them within bounds.

Sharp sand drainage properties

Posted: 24/07/2012 at 15:54

I have been reading around and asking about sharp sand and drainage.

That said, all sands improve drainage as they create channels or pores for the water to travel through. There are some fascinating, (and a lot of very dry  ) books on the subject - mainly aimed at sports turf management.

That is a quote from a Soil Management student.


So Daituom have you read these books?
