Wanting to know if it is safe to spray Roundup weed killer on fruit and vegetable plants.
Round up will kill any plant it comes in contact with. Only use it on or around plants you want to get rid of. If you are using it near plants you want to keep, use a spray shield as the wind can blow it onto desirable plants and kill them unintentionally.
How can I stop grass from growing in my gravel driveway without using any toxic chemicals or without digging up my driveway and installing a barrier fabric?
I have a huge bark covered hillside covered in various types of foxtails. Next spring we will use a pre-emergent to head off the problem, but we are trying to figure out a way to get rid of the current population. The largest population is exactly where my dogs run along our fence. Is there something safe we can use to kill the seed pod so they quite reproducing? Also, can you recommend a pre-emergent for next spring that is safe for the dogs, yet will kill the foxtails? There is nothing growing except for weeds on the hill and our newly planted palm trees. Thank you for any pointers! RJ

How do I remove sticky bushes that keep coming back every year?
Basically there are two approaches, digging, and herbicide. It can be really hard to get every piece of root when you dig, which is why many people prefer an herbicide that kills the whole plant, leaves and roots. This article tells you more about the kinds of herbicide from which to choose: https://www.gardeningknowhow.com/plant-problems/weeds/conventional-weed-killers.htm
However, it also occurs to me, because you said sticky bushes, that you might be referring to the sticky quality of the bushes. If that's the case, your bushes, or possibly the trees above them, are infested with sucking insects that are dropping sticky honeydew. If you kill the insects, you can wash the sticky away with soap and water. This article will tell you more about these pests: https://www.gardeningknowhow.com/garden-how-to/info/what-is-honeydew.htm
What is the best way of removing brambles and prevent them coming back?
If you are looking at a large area, probably you're going to want to use an herbicide. I expect a post-emergent will be necessary for the woody plants. You're also going to be looking at some continued treatment and digging for a couple of seasons.

I don't know exactly what kind of home gardening help you have available in France, but if you contact the nearest botanical garden, they ought to be able to direct you to sources from whom you could learn of the products available in your area.
I have cleared my garden when I moved in, as it was overgrown, and intend to start work on it next year, but the problem is every 2-3 weeks it is covered in weeds. I dig them out but I want to get rid of them permanently before I start. How do I do this?

I have a bramble in my garden which is starting to take over. Please can you tell me how to stop it without killing the rest of my shrubs?
You can use Round-up, but only in a very localized fashion. Cut the bramble back as best you can and then paint the fresh cuts with Round-up. The bramble will suck the Round-up into its roots and this will go a long way to killing the roots. You may have to repeat 2-3 times, but every time you do it, it will weaken the bramble.
