looking back it appears I planted a 4" plant from Lowes around July 20th (likely the weekend prior to this, so say I planted a 4" seedling pot on July 16/17)
we had several weeks in Aug where multiple days were 100F or above for the highs, and the soil is volcanic ash (silt) that's loaded with an abundance of everything except nitrogen, so the cantaloupes and maters really took off without overgrowing.
sweet corn I sowed in a new bad on 29 July is now 48"-54" tall and starting to have the beginning of what will be ears. water and warmth without humidity really get some plants growing vigorously.
that cantaloupe in the upper right corner dropped off the vine at lunchtime today when I gently lifted it, so it's inside and awaiting breakfast later this week. just under 2-1/2 pounds. exciting to finally have a homegrown melon after decades of discouragement from sporadic attempts
