Overall, I think it is a great planting method and will definitely do it again.
So of the things that I would do different:
- Plant the corn first, peas and squash about two-three weeks later
- Be sure that the squash that I am using is vining squash and not bush squash
- Make sure my soil is fertile enough to actually grow corn
- Give more space between planting rows. I started out with 1.5' between rows and ended up with no space between rows for walking and harvesting.
But there were some great things about this method:
- When thrips found my corn, they only found one planting of it. So all the other plantings were unharmed.
- I didn't have to spend extra money or time with pea trellis'. When its time to pull everything, I won't have to untangle peas from my trellis.
- I would also imagine that if I were attacked by some squash pest that they would have only found one grouping of my squash; as the interplanted method may confuse them or cause them to think that is the only squash available for tasting. However, I think a summer planting took care of most pests and they have faired well thus far.
- I did also plant some peas on a trellis away from the Sisters. I found that the peas planted with the squash produced pods earlier than the peas on the trellis. However, thus far, the corn-planted peas are shorter.
The only bad thing I found with this was a result of human error. Basically timing and spacing. The squash was planted before the peas and had basically taken over the bed before the peas got started.
