Well, it's been a good summer - a productive summer and I've learned a thing or two about container gardening. One of the things I learned was that you need a solid staking system for indeterminate tomatoes. I use sub irrigated planters and had a single stake on each end with twine running between. Well, that didn't work too well, as the plants became too heavy for these particular stakes (black plastic). When the weather got hot, so did the plastic and with the weight, they bent - a lot.
So I used a four stake system made out of cedar with bamboo inserts. It's working really well. Here's a pic of the project in progress:
