Early crop, sort of. It is the first in hopefully a large harvest of cucumbers, although there seem to be a lot of male flowers and not so many fruit bearing ones. Time will tell. In the meantime I am watching with fascination how the springy curlicues grab hold of supports.
Cucumbers yield lots of fruit and will be very refreshing and flavorful if you give them enough water. I know watching veggies bear fruit is not that fascinating for others, but I am completely hooked: the picture above will bring an immediate “Awww, how cute!” to my mind.
If you have limited space, grow them on a trellis. They will be happier and healthier, take up less than two square feet per plant and yield more.
