Have you ever planted winter squash and it grew in a direction you didn’t want? Here is a good tip for how to tell which direction a vining winter squash (versus a bush variety) will grow. I will use my giant pumpkin as an example but any winter squash that is a vining squash will act the same.
Let’s say you plant some vining winter squash next to a wall or on the edge of a garden bed and you need it grow away from the wall not into it or into your squash bed not out of it (good luck on that one!) When the plant puts out the first two leaves as I have described in previous posts, these are called the cotyledon leaves (baby leaves) and don’t look like any of the other leaves it will grow afterward. All leaves after the cotyledon leaves are called true leaves.
Sooo pay attention to that FIRST TRUE LEAF. The plant will GROW IN THE OPPOSITE DIRECTION FROM THE FIRST TRUE LEAF. If I’m growing them inside for a head start, it is easy to mark the container as you will not remember which one was the first leaf (trust me!) when the second one appears. I just take a marker and mark the opposite side of the pot so I know when I transplant it into the ground which direction I orientate it. If I grow directly into the soil, after the first true leaf appears, I gently dig up a big amount around it and gently lift it and the dirt so as not to disturb the new roots and rotate it in the direction I want it to grow. For those who are growing their winter or summer squash seed in the ground, it is too early. Wait till May 15th (our first frost free date) to plant directly into the ground when the soil and weather are hopefully warmer.
