Anyone dismantled and moved a greenhouse before??

If the sections can be moved without taking out the glass it will be so much quicker and easier and you are less likely to break the glass.

We have moved our wooden Alton 5 times and I should think the principle is the same.

Door first.  Then roof sections. Then sides.  Then ends. Have lengths of wood available to brace the bits when you remove sections.  Two people make it simple. Do not do it when the wind is blowing.  Do not leave it incomplete overnight. If the nuts and bolts are difficult to undo, apply oil to them and leave overnight for them to loosen.  Make sure you have plenty of new bolts, clips, etc before you start, so you don't have to go and get some more mid-construction

It is far easier to wash the glass at ground level, especially the inside of the roof sections.

When you reconstruct make sure everything is square.  Start by putting the end opposite the door in place and brace it firmly.  Then off you go.

In my experience it is inevitable you will hear the tinkle of broken glass. But with luck it will only be one sheet.

Uncoppicing

Coppicing, you cut to the ground.  I think what you have done is pollarding. It sounds as though this poor shrub has been incorrectly pruned in the past.

It may be best to cut your losses and start from a new plant. Cytisus are not very long-lived shrubs, I think 20 year + is pretty good going.

Best time to transplant trees.

After leaf-fall, and when there is no frost in the soil.

How to get rid of excess soil?

Ah, maybe it was a mix of topsoil and sub-soil?  Or had they been kept strictly separate?  The top soil I would keep every time, but not the sub-soil.

What Hedge to plant ??

Beech is nice.  If kept as a hedge it holds on to the dead leaves through the winter.

Rosehips

No, the hairs are not harmful, but they have no place in a syrup or jelly, and are always removed for a preserve as far as I know.

Magnolia and blossom trees

I recently read that magnolias should be sufficiently shaped before you buy them.  Apparently if you prune older magnolias they will produce vertical 'water shoots' rather than flowering branches.

Himalayan Balsam

Well, I think it goes in the same category as Russian Vine.  

There are some plants it is just idiotic to encourage.  It will get out of control.

Rosehips

The easiest thing to strain through is an old pair of tights. They are very easy to hang from a hook in the ceiling or door jamb.  When you prepare the rosehips by taking out the seeds remove as many hairs as you can. Ensure the hips are ripe; they should be by this time of year.

But you must strain the liquid, seiving is not enough.

Quince

The Spanish use the big quinces which grow on trees for membrillo, not the small ornamental quinces more likely to be found in the garden.  The will not harm you, but the large quinces are much more suitable. They appear in the shops towards the end of the year.
