Morning Glories: Do I pinch my Morning Glories?, 1 by orange_knickers

Hi!
Morning Glories are new to me, gardening is new to me actually, so don't laugh! I planted two Heavenly Blue MG in this pot. They are growing quite fast but have now reached the top. Should I pinch the tops? Will this encourage side branching? The obelisk is pretty sparse, some new growth would be nice. Or should I just pop a couple of more seeds in the pot to cover it up?

Thanks for the help,
James
