Some giant pumpkin plants are doing very well since being put into the soil and a few others have stalled. The seeds from last year’s 1,177 pound pumpkin that placed 1st in BC have had the most vigor so far.  They have been performing better than all the other plants.  It’s good to use pure water for the first few weeks after you plant them.  It’s always good to use unchlorinated water as chlorinated water can kill beneficials.
