22 Tomato and 11 pepper plants, spacings a little tighter than it should be on some of the tomatoes, but it should be okay.
Looks great. I’m excited to see how they do!
If I’m seeing this correctly, most of these will probably not produce.
The recommended spacing for tomatoes isn’t for the root spread, it’s for the canopy. Because of this, the ones at the corners may do okay, but they will shade all other plants while the sun traverses the sky during the day inhibiting their growth.
You also have a watering problem where the tomatoes will need 4x the amount of water those peppers want, and the wetter soil will inhibit the pepper plants’ growth. They generally need to be planted in separate boxes as the soil conditions are completely different.
The planter goes more or less north/south, so the canopy may get a little dense, but there’s also determinate and indeterminate as well. It’ll get plenty of sun, I know I’ll need to do some pruning, so there’s no reason why it can’t all produce.
The watering isn’t something I’ve read about, there’s plenty of salsa garden planters and layout ideas out there. Now that being said, I don’t have the climate for peppers anyways, and wouldn’t the tomatoes drink enough water to keep the peppers not swamped? That’s my understanding of stuff I’ve read. It’s also more to do with standing water, this won’t have standing water.
I’ve done this before without issue.
Recommended is 16-30 for my varieties, it’s not too much under. And those are all guidelines anyways.
