I sowed some Aubergines & Peppers (early long purple 2 & sweet colour rainbow mixed), at the end of March, indoors. They have been in the greenhouse in troughs for some time now, but the 2 pepper plants are only between 5 & 6 inches in height ( to highest leaf), while the 2 Aubergine plants are 6" & 12". The plants look healthy enough, except for the lack of height. They are watered about every other day, and are protected from the full sun- when we get it, that is, with shading. My Tomatoes were sown at the same time & some Squash plants a month later, both are doing far better. Any thoughts anyone?
