Fox or cat poo are things I really don't want and to get on my gloves or anything else.
The garden has come to a sort of messy impasse, which luckily suits us.
Things I can’t pick up with my bare hands? Like the dog poo bags that local dog owners leave hanging from nearby bushes like a votive offering to the god of canine excrement? I use a litter picker.
If you live in Derbyshire, as I do.
1-Are there any problems that you come across whilst gardening?
There are pests which attack and destroy my plants- slugs, snails, mice, birds, my dog and my children.
2-Do you have a piece of land that is ever littered with leaves, grass clippings, twigs, etc ?
Oh yes, I have several deciduous trees. I don't rake it up very often. My dog enjoys playing in the leaves and it all disintegrates quite quickly that way.
3-Do you come across any items that you cant pick up with your bare hands? If so what ?
Animal dung, squashed snails, dead rats, nettles and brambles (painful to the touch).
4-Are there any loose objects that are too abundant to be picked up by hand?
Hedge clippings... so I sweep them up.

2, no
3, gloves help
4,no
2 - being surrounded by deciduous trees, always loads of leaves in autumn, but worth the effort of collecting for mulch
3 - snails; dead baby birds; poo; anything spikey or stingy
4 - ugly old stones put down by previous owner

2. Yes. I'll clip flowerheads, twigs, leaves and let them drop. I'll only clear big leaves or tree shedding off the lawn.
3. Bird and hedgehog poo.
4. No.
