Here are five of the roughly two dozen reasons why it's hard to grow some things around here. Like... just about anything edible or having a trunk. LOL See the red arrow in the foreground pointing to last year's glossy kales. The kales mark the front of the regular garden. The deer are along the back edge of that garden. And the sea of foxtails behind the deer on the right is the "pumpkin patch" where we try to grow vine crops and corn. Lately we've been seeing them nearly everyday, but sometimes of the year they're less "present". Even so, if it weren't for regular "egg-sprays"* some of my smaller trees would never get a chance to get bigger.
* Egg-spray is just an egg shook up in a gallon of water and strained into a pump-sprayer. Deer are supposed to find the scent disgusting. So far so good. You just need to reapply after you get a few good rains, which can be a pain in a really rainy season. We haven't had one of those in a while! LOL
Disclaimer - As with anything, I'm not advocating you use it. So don't try to hold me liable for anything. Do your own research before you try anything at home. For instance, I don't spray the things that we'll be eating raw, when it gets close to eating time, because of the potential issues with bad things in raw eggs (like Salmonella). But I feel free to spray away on things that'll get a good cooking before they're eaten, and on inedibles.
Sometimes I add a couple of tablespoons of fish emulsion to the spray to do a foliar feeding while I'm at it. Might as well "kill two birds with one stone." And I figure that could only make the scent even more disgusting - raw eggs AND rotted fish, yummm!!! But in general I don't do a whole lot of fertilizing anyway.
