We have two brick planters on the east side of the house we converted to square foot garden containers. One of them is 2 feet x 8 feet and the other is a square, 4 feet on a side, in the nook between the back of the house and our screened porch.
The plants in the nook look extremely healthy and have some nice-sized green tomatoes. The plants in the other planter aren’t happy. I’ve had a few ripened tomatoes – all with blossom end rot.
According to what I’m reading, this is caused by uneven watering, too much fertilizer, or a lack of calcium. We have an irrigation system, and everything seems to be thriving with the once a day watering they’re receiving, except for this planter, so I don’t think this is the reason. I fertilized with some tomato food when I first planted, but none since. I suspect a lack of calcium. I sprayed the plants with “Rot-Stop” a couple of days ago. I then worked some bone meal into the soil around each plant yesterday morning. I’m not sure if there is anything else I can do, so I’ll just watch and wait a bit to see if this helps.
One of our favorite things in all the world is fresh sliced tomatoes, so I’m hoping that we end up with a good crop!
