Bramble invasion

Pharmacy or vets.  I think you use hyperdermic for Japanese Knotweed rather than bindweed. Though if you cut the Knotweed just below a node you can inject weedkiller into the stem with a syringe without a needle

You can get disposable syringes also from pharmacy or vets.

Fruit trees

Bees do it better.  Self-fertile fruit trees will always do better with a compatible pollinator.  It might be better to concentrate on just one fruit rather than growing one of each.  Victoria is a plum everybody knows the name of but it is a challenging plum as it suffers from diseases. Conference is partially self-fertile.

Any ideas as to what this water lily is?

Well, Benetts Water Gardens seems to have a good selection.  It only took 10 seconds to find them through Google, lots of images to look at.

Even more confused about fruit tree choice now...

They are very variable, so you cannot guarantee you will get a well flavoured one until it is well grown. They are essentially wild.  And their flesh to stone ratio is not very good.

Perhaps you should go for a named one.

Bramble invasion

Wickedly, I was going to suggest you threaded the bramble shoots back through the fence, and hope your neighbour deals with it.

Aunt Betty, I find digging out is the only efficient method of clearing brambles. And the cheapest, and safest.  Weak little bramble plants will grow from any big roots left behind, but they are easily dealt with.  I once cleared a large-ish garden of 8ft high brambles that way. When dried out the roots burn well. 

Orange Hawkweed (Hieracium auantiacum)

I know it as 'Fox and Cubs' and I have a patch of it that I encourage!  It's nice in long grass, on a bank or wall.

Funny how we look at plants differently.

Even more confused about fruit tree choice now...

Bullaces are on their own roots I should think as they are really a wild cousin of domesticated damsons and plums. They wouldn't need a pollinator.  IMO I wouldn't bother with a bullace if I could grow a better damson/plum, though they would be fine somewhere like a field or hedgerow.  I regard their fruit as food for free.

What's wrong with these tomatoes?

How are you watering the plants.  Is it just the effect of using dirty water or getting water with fertilizer in it on the fruit?  Does it wipe off the fruit?  Do they taste OK? Is there dirty water coming off the roof.

My policy is usually to wait and see rather than discarding healthy-looking plants.

Ash Tree Stump

You can get someone in with a stump-grinder. 

Damson Crop for 2012

When they are ripe.  This year it is pointless going by the calendar.
