Sue is planting giant pumpkins again this year (yes, it’s planting time here in L.A.) Last year, she grew a 300 pounder, not bad for a first year attempt experts say, and saved seeds for this year.
How fast do giant pumpkins grow? She put a seed in a 12 ounce paper cup to germinate. A few days later, the seed was cracking with a little green appearing but no leaves as yet. I transplanted it into a larger pot and noticed it was already root-bound. This for a seed just turning green with no leaves.
Today, just 2-3 days later, the leaves are three inches long.
