Growing and Freezing Butternut Squash

My favorite vining vegetable in the whole wide world is the butternut squash. This season I grew a delightful little variety of the butternut squash called “Honeynut” in my elevated Pizza Garden. You can see by the photos that the bitty Honeynut baby is a mini squash that is super cute and, believe me, will be as perfect on your plate as it is in your garden. If you did not grow butternut squash in your garden this season, definitely put it on the garden design plans for next year.

How to Grow Butternut Squash

Growing a butternut squash is super easy. Here’s what you do:

    1. If you have an in-ground garden, amend your soil with Kellogg Garden Organics Garden Soil. I planted my squash in containers and used the Kellogg Garden Organic Select Garden Soil Formulated With BiocharMax soil in my elevated beds.
    2. I mix in one part rotted manure with the bagged soil.
    3. Then I fertilize following the package directions on the Kellogg Garden Organics Organic Plus Tomato, Vegetable & Herb Fertilizer. One advantage to the Organic Plus fertilizer is that it contains kelp meal which is a great source of micro- and macro-nutrients which will help give your plants a boost.

Growing Squash in a Pizza Garden

I’m sure you’re wondering why I grow my squash in a pizza garden? It all started when I went to Rome, Italy to visit my daughter and tasted a delicious pasta sauce made out of pumpkin. Butternut squash and pumpkin melt down easily with a little olive oil and salt in a pan and can be turned into an Italian sauce or soup quite easily. Definitely a yummy change from the traditional American sauce creation and perfect for pizza. Thanks for joining me to learn how to freeze your butternut squash abundance!

  1. I am definitely going to try the crock pot method with the kids. They love the mashing part and I love turning it into soup. I have 4 amazing ones just picked from the garden! Thanks for the reminder to get it ready!
