Not all varieties of squash are suitable to grow in-house. However, you can choose those that have smaller vines as they occupy less space. Butternut, cuarzo, and zucchini are good choices. Some variants like the kabocha and zephyr are suitable for growing indoors.
All squash plants grow into a vine from seeds. So, it would be wise to separate the hills to accommodate the size of the fruits. Else, you may need to replant the vines. Make sure that the soil is rich in nutrients. Organic methods like compost and manure work best with squash plants. While the months of sowing the seeds vary, you need to provide 6 to 8 hours of sunlight to each plant to make every season successful.
