I bought a Pumpkin Plant

Oh dear me, when I visited the garden centre I went a bought a pumpkin plant, now it says on the label that it needs about 10 square feet to grow in!!!
Where am I going to put it is the next question?

I also bought a Sweet Pepper plant which can live quite
happily in the pot I've put it in.

Planted on 11th May to stay indoors.
