As I look back to the last time I re potted the plants I used some cheep priced potting soil I got from Home Depot. I had no trouble with moving the plants back and forth to the pump house. The plants looked good at that time, after re potting the plants slowly began to look stressed and then I found the spider mites, I wonder if they might have been in the potting soil?
I have been growing great gardens for the last 10 years and this is the first time I have ever seen spider mites
I built a solar water heater and circulated it through 1/2 " poly tubing which I had buried approx. 10 " below the rows where I intended to plant vegetables.there a 4 rows 3 feet apart. The ground temp. in early may was 43 deg. in 2 days the temp had rose to 78 deg. This allowed us to plant a month sooner .
Sorry for the information overload, But I am thinking of planting a row of weed. What is your thoughts?
