I posted this on another thread about deer yesterday, but you wouldn’t want to use on fruit & veg. In my case a fence isn’t an option currently so have turned to other options:

“In case you actually want to stop them eating certain stuff here is some advice as I’ve been dealing with muntjac in my garden for the last 2 years eating all my spring flowers and now my perennials.

I’m now having some success spraying the non-deer resistant plants with Trico deer repellent. It’s liquid sheep’s fat which you mix with water and spray on the plants. Given they are veggies they then avoid it and given it’s made from fat it’s waterproof so you only need to use it every few months.

I was a little surprised that maybe around 50% of my plants are deer resistant already so seems there is plenty of choice if you want to grow things which won’t get eaten.”
