Squash, soecifically to say the yellow squash which is close relative to zucchini are delicious, nutritious, and beautiful-looking vegetables that have a creasy inside.
However, at times a yellow squash might not have the natural creamy inside, rather it can have a slightly greenish-looking interior. Thereby, naturally you might think of the reasons why your bought/grown yellow squash is green from the inside.
Thus, let’s straightly jump into the answers explained ahead regarding this topic.
Why Is My Squash Green Inside?
A notorious plant virus named the Cucumber Mosaic Virus (CMV) is mainly responsible for infecting and turning a yellow squash inside green. Besides, cross pollination and squash variety confusion are the other two reasons that can make a yellow squash have a green inside, instead of a creamy inside.
Many distinct factors and probable reasons such as a natural phenomenon or an effect of an external stimulant like a virus, insect, or others can cause a yellow squash to have green inside.
Here, all the reasons behind a yellow squash having a greenish inside are explained as the following.
Cucumber Mosaic Virus/CMV:
The Cucumber Mosaic Virus/CMV which is also known as the Yellow Mosaic Virus is considered as the prime reason that causes a yellow squash’s creamy inside to turn into a green inside.
A yellow squash affected by this Cucumber Mosaic Virus is likely to have a mottled effect like yellow and green color will be battling on the skin of the squash (half yellow and half green with green patches). and the leaves of the squash will turn white.
However, the most common sign is a misshapen squash or the squash plant isn’t yielding many squashes as it should be.
Host plants like weeds or flying insects which are also called carried insects (aphids, whiteflies) usually spread this CMV in squashes.
Cross-pollination is another reason behind a yellow squash having green inside. It happens when every year you are gardening in the same garden by planting your own stored up seeds.
As the saved seeds of parent zucchini and yellow squash plants will cross-pollinate and yield offspring with mixed characteristics.
For example, if you have grown zucchini in the same yard the previous year and have planted yellow squash this year, due to a possible cross-pollination, the yellow squash may have a green inside.
Confusion In Squash Variety:
Sometimes, it happens that the squash plant is producing healthy squashes but due to mislabeled seeds, or vague cultivar color can create a confusing situation where the quash might have green inside.
For instance, cultivars like the “Gold Rush” are yellow whereas maximum zucchini varieties grow in green.
Also, two summer squashes, patty pan and globe either can grow in green or yellow color. So label correctly your saved seeds to avoid this confusing situation.
Is Squash Supposed To Be Green Inside?
Squash isn’t supposed to be green inside because naturally squashes have an orange, a creamy, or sometimes a white inside.
But if the quash variety is infected with the Yellow Mosaic Virus aka CMV, the infected squash/squashes can have green tints inside which obviously isn’t a normal thing to see on a squash.
Some squash varieties can have greenish inside when they are not ripened yet which is natural.
Are All Squash Green Inside?
Seeing greenings tints on a squash inside, some of you may think whether squashes, specifically spaghetti, butternut, summer, yellow, crookneck, red kuri, kabocha, and winter squash have green inside or not.
Thus, for your information, below the insider color of these squashes has been described.
A spaghetti squash’s flesh tends to be either bright yellow or orange not green. But if the spaghetti squash has green inside accompanied by soft texture, it means the spaghetti squash is rotten.
Butternut squashes have a deep orange inside without any trace of green. However, if the butternut squash isn’t ripened fully, it naturally can be slightly greenish inside.
Summer squashes are creamy from the inside with no trace of green tints. But when it’s affected by Yellow Mosaic Virus, it can have green tints inside.
Just like the summer squashes, yellow squashes have a creamy inside. And when they are infected with the CMV, their interior start to have green tints.
A crookneck squash has dense and pale yellow flesh inside with edible seeds. If any crookneck squash seems to have green inside, it’s because the Yellow Mosaic Virus has infected it.
Red Kuri Squash:
Inside, a red kuri squash naturally has a firm, orange flesh with a fine texture that tastes dry but has a rich chestnut-like flavor. Sometimes it can have greenish tints around its seeds due to not being fully ripe.
Kabocha squash isn’t green inside, rather it has a bright yellow-orange flesh inside.
When winter squash is not fully ripe, it can have greenish inside. But upon maturing, it will have a whitish-yellow inside.
Is Green Squash Ok To Eat?
