Can I call it twin baby? It blooms at the same time and came out from the same location. But I know, only I of it will grow well…… I found out that my cucumber plant does not do well if there is more than one cucumber grow on the treat the same time. Only if I harvested the big one, then the small one will start to grow well. The plant will also start to bloom more female flower when u harvested the cucumber. ya, my guess is correct. I already harvested the left cucumber but the right one still remain in small size.
