Gardening: Jalapeño Update

I read online and in a few books that when flowers show up on the jalapeño plant to add some epson salt to the water and it will produce more jalapeños than with just plain water. Last year I had 4 total jalapeños on 2 plants. So it didn't seem like a worthwhile plant unless you have a lot of plants. So I tried this epson salt tip. Within 2 days of watering the 8 plants with a 1/2 cup of epson salt added to the watering can, the plants had a ton of flowers on it. Now, I have a lot of jalapeños. 

I am experimenting with where I have placed the plants. 2 pots with 2 plants each are placed on the Northeast corner of the house with no other plants around. I also have 2 pots with 2 plants each placed on the East wall of the house by the front door. There are hedges across the pathway. The ones on the northeast corner are growing better than the ones by the door. I need to figure out a way to put plants on that corner without killing the grass. I am thinking a platform of sone sort might work. Still thinking that one out. 

I will give another update once I start harvesting them.
