Blueberry Thai

Small plants now so moved into 5 gallon grow containers and their veg soil medium. Soil is a cheap local fertilised soil with coco coir. I check the soil for dryness twice per day before deciding on water. The temp is a concern...had a couple of days over 50c most days around 42c but the plants seem to love it. Had some insect damage to some leaves so treated one dousing of veg oil, organic soap and water..sprayed as mist..seemed to work well. My marigolds have mealy bugs and that mixture (tested on the marigolds) killed all the mealy bugs.
