I’ve grown the 3 sisters guild twice now, both times with different results. It can be challenging in a Northern climate to grow some of the heat loving plants as it’s common to get frosts in May and September. Corn and winter squash not only require long hot summers but they’re also heavy feeders which makes them demanding plants here, and if you get a summer full of rain well then you might be hooped. Both also take up a lot of growing space. Over my 5 years of gardening I’ve had lots of success with growing squash in our climate, but not so much with corn. Corn is the sort of heavy feeder that benefits from a boost once a week or so to get excellent results (and I couldn’t be that bothered).
What is the 3 sisters guild?
The 3 sister guild is a growing method adapted from the Native Americans that is seen frequently within the permaculture realm. It contains corn, winter (non-bush type) squash and pole beans. The pole beans climb up the corn stalks, anchoring the corn into the ground and aid in restoring nitrogen. Allowing the beans to climb the corn reduces the need to build a trellis. The trailing squash grows around the corn stalks, covering the soil which can help smother some of the weeds and making a good use of space. The spiny squash vines have the added benefit of keeping the corn safer from racoons.
Guilds are popular with permaculture gardening as you’re creating a little ecosystem and attempting to get plants to work together, reduce pests and disease and to restore some soil nutrition.
First off because the bush beans were an accidental mix up, they still produced beans, but not with the effect of climbing up the corn like they’re suppose to and were thus hard to harvest (no one wants to climb IN squash vines and get their arms more scratched up than they need to). On one hand, for whatever reason, we ended up with only a few corn but 18 spaghetti squash just from ONE squash plant. 18. Record breaker there for us. So the squash turned out great, the corn and beans not so much. We also had an exceptionally wet June, 5 weeks straight of torrential rain which was a factor.
The 2nd time we grew the 3 sisters guild we adapted the below diagram from: Renee’s Garden (check out the site link for lots more 3 sisters guild info, with more diagrams on exact planting spacing & setting up the mounds).

We had to make some adjustments as we didn’t have a bed large enough, so we used one of our keyhole shaped permaculture beds. Below is how we ended up growing the guild.

Year 2 Review:
The second time we tried growing the 3 sisters guild, something funny happened. Half of the bed produced amazing corn but stunted almost all of the squash, and the other half grew amazing and early squash but stunted the corn. The beans honestly didn’t turn out, you have to wait to plant them until the corn is a large enough for them to climb it, and because of this the beans didn’t start producing until the end of summer. They also grew much taller than the corn stalks so we ended up with beans that had no where to go. The yield, based from the size of the bed, was dissapointing. I do believe that the corn and squash would of greatly benefited from a weekly or bi weekly fertilizer but that is not how I usually garden. I think the soil needed to be richer, and based off the above diagram I think the squash and corn are way too close together which created so much competition. We also had 3 weeks of rain in June, which seems to be becoming the norm the past couple of years here. I did plan for it and planted everything during the May heat wave with better results than the previous year.
Below are some pictures of the process.

- It’s neat to have 3 plants all working together.
- Corn acts as a trellis for the beans.
- Beans help anchor the corn down and put back Nitrogen.
- Squash vines help prevent racoons from getting at the corn.
- Squash vines make a good use of space by growing around the base of the corn.
- Increases the diversity within one growing space.
- It looks really cool!
- This guild might not work well with short growing seasons.
- Corn and squash may compete too much as they are both heavy feeders
- This guild really benefits added fertilizers..or you can plant fish heads & bones under the plants like the Native American’s did
- You have to wait for the corn to be the right size for the beans to be planted.
- If the corn grows slowly your pole beans are delayed.
- Not beneficial for rainy summers.
- You need a very large growing space.
- The beans can grow taller than the corn depending on which corn variety is used. We used Golden Bantam both years and it’s a shorter variety.
Will we grow the 3 sisters again?
To be honest, no, at least not for a few years. In fact I made the decision this year not grow corn at all unless we have a larger land area to do so. Even though corn tastes great, I personally can’t be bothered to spend so much time and space on such a heavy needy feeder. Especially when the corn often ends up in your poop (hey it happens to all of us, it’s like slap in the face to a gardeners hard work!).
That summarizes my experience growing the 3 sisters guild. Have you grown this guild before? Did the method work for you? How did you space your plants?
