I've planted Pumpkin Mars seeds this year for the first time in growing pumpkins! I've been told they grow into large plants. How big are the pumpkins & How big a container or supporting canes do I need? Any help please? Thank you.
My sister's kids have grown them. They're on the small side, for pumpkins, around a couple of kilos.
All pumpkin plants can grow into monsters if you let them. You can control the size by nipping out the growing tips of the main vines when they get to 6 or 8 feet. The bigger the container the better for pumpkins, in my experience. They need plenty of moisture in summer and small containers will dry out too quickly.
Pumpkin vines can be left to trail if you have the space. Or you can grow them up a trellis or fence.
