Rumbo Squash: How it grows

Oct. 9 the overnight temperature at my Vassar Farm community garden plot was cold enough to frost burn the squash leaves. With the squash vines dead, I harvested the remaining Rumbo squashes, all of which were immature.

The frost provided the rare opportunity to gather squashes at several stages of maturity for photography.

I started harvesting fully mature Rumbo squashes around Sept. 1. I’ve noticed in the past, and it was also true this year, that a vine often sets new squashes after its mature squashes are removed. That is why I found so many young green squashes in October.

Rumbo squash vines sprawl all over the garden. My Rumbos were planted slightly off-center in my 20’x40′ plot. By frost the vines had reached all sides of the garden and started climbing the fences, so the vines were about 30′ long.

The squashes weight in at 12-18 pounds. The harvested squashes in these pictures are 12-15 pounds, except for the baby.

The smallest Rumbo is young and quite tender; more like a summer squash than a winter squash. I grated it and used it in place of zucchini in my standard recipe for zucchini bread. Yummy!


  1. Hello Mary,
    Love your photos of the different stages of Rumbo squashes, great idea. What are you going to do with the immature squashes?

    • When they are so immature that the skin is still soft, I use them like summer squash. Half of the little one went into ‘Zucchini’ bread and the remainder will probably be sautéed with onion and anything I can find in the garden.

      The dark green one is already starting to ripen on the blossom side so its skin is hard. It must be peeled before using. It might be sautéed or put in a soup of mixed veggies. Or I might just leave it to ripen in the basement and not think about it for a while.

  2. I haven’t heard of Rumbo before; how fun to have a squash you can use green or ripe.

    • It’s not just Rumbo, I harvest & cook baby winter squashes of all types if a frost is certain.

  3. What an interesting and informative site you have! Do you roast and eat the rumbo seeds like you would pumpkin seeds?

    • Yes I do roast & eat Rumbo seeds. I also roast butternut seeds, which are a bit more thin-skinned than Rumbo.
