I've both been a volunteer and a host of volunteers. It can be a good thing and a bad experience from both sides - but lots of learning is always the result. Communication is key.
I'm glad I started out on the volunteer side, it gave me a lot of insight for what to say and how to treat people who were coming to work at my own place. I tried to mimic what I liked about the best experiences I had. The main thing I took away from being a wwoofer is that it's nice if the work schedule is formally organized. You know what part of the day you'll have to yourself and what part of the day you'll be working.
Sometimes farms can over or understate their conditions or expectations. As a wwoofer (I'm going to use this term for all volunteer positions) you arrive thinking you'll be doing one thing and then find that most of your time is spent doing another. In our ad, I try to be VERY clear about the living conditions, working arrangements, the kind of food we eat, how we shit and shower, and anything else I can think of.
I asked everyone who stayed with us if my description of the place matched the reality of things here, and everyone said that it did, even if they didn't end up liking it as much as they thought they might. I consider that a victory even if the relationship didn't work out between us.
I also state on the first day that anytime something is unclear, PLEASE come ask me about it.
I continuously ask people for feed back, and after a week we sit down and have a formal "how is this going" session.
I had some experiences wwoofing where people acted like you should know what they meant or what they wanted and couldn't be bothered with questions. That was frustrating, because I'm good at following directions -- if they are given. So I tried to give good instructions and be happy to
answer any questions and demonstrate/re-demonstrate what I wanted.
It is a lot of work to get other people to do your work.
Sometimes in their enthusiasm to come to your farm, wwoofers can overstate their experience. I had two people here this last summer who told me they had "lots of
gardening experience," but they didn't know the difference between a bean plant, a squash plant, and a carrot top. I felt like I had been lied to, plus they didn't really catch on all that fast, and that was a big part of the reason I asked them to leave after two weeks (I gave them a week to figure out something else, they left in two days). If you're inexperienced, please be honest about it.
We live far enough away from anywhere that most people are traveling a significant distance. I encouraged everyone who wanted to come here to bring a bike with gears, especially if they didn't have a car. No one did.
I also had some people who wanted me to drive them around a lot - "can I come for five days and then go to this festival and then come back?" Uhm, no, not if you expect me to drive you two and from the nearest bus station (only 100+ miles round trip) twice in one week.
At one point we had four interns at once, and it was too many. Having more people here drastically changed how I spent my time. We use a woodstove to cook, and this means that we all eat the same thing at the same time - there is no separate wwoofer kitchen and I don't cater to special diets. That eliminated a lot of people right away, I'm sure.
I tried letting the wwoofer's cook a few times, but using a woodstove takes a long time to get used to. They took a long time and burned too much
wood to make not enough food. And there was soot all over the kitchen at the end - that I had to clean off. So, I do all the cooking and a whole lot of the cleaning. It ended up being how I spent most of my day. I like taking on those tasks, but with fewer mouths to feed I didn't have to spend SO much
energy and time preparing food and could have more time for
gardening. Fewer interns ended up being better for us.
The number one frustrating thing is the attempt to line up wwoofer's visits. One person tells you they're coming, so the next four people that write you say "sorry, that week is taken" and then the original person cancels and you're left with no help at all. That's how I ended up with four people here at once - I started overbooking so that SOMEONE would be here and presumably the rest would flake at the last minute - and then they all showed up. Sigh.
Also, everyone seems to want to come in June. I had a million and two offers for June, and like, four for the rest of the summer.
After the roller coaster of the "first timer" summer, I think that I prefer long term helpers who get paid a little to be here. We had one person who was here from the beginning of June til the end of November, we paid him $200 a month, and he's coming back next summer. He's not perfect, but we aren't either, and luckily perfection isn't required to make this kind of thing work out. The relationship benefited both parties enough to continue it in the future.
