Black kicks off the conversation with a miniature pumpkin he recently harvested from his garden. Planted over the Fourth of July weekend and harvested nearly three months later, the pumpkin is a reminder that gardening can produce unexpected results, even when plants are not labeled with a specific variety.
The small pumpkin developed on a vine that experienced powdery mildew, a common plant issue that can cause leaves to develop white patches and eventually die. Despite the challenges, the plant still produced a healthy pumpkin, demonstrating that even a relatively low-maintenance gardening approach can yield a successful harvest.
Understanding How Pumpkins Grow
Pumpkins come in a wide range of sizes, from miniature varieties to enormous Atlantic Giant pumpkins grown for competitions. However, gardeners do not always know exactly what they are growing, particularly when plants come from community sales or other sources without detailed labels.
Black explains that pumpkins belong to the same plant family as squash, zucchini, gourds, and cucumbers. These plants produce male and female flowers, each playing a different role in fruit development.
Male flowers supply the pollen, while female flowers contain an immature fruit at their base. Once a female flower is successfully pollinated, that small fruit can begin developing into a pumpkin. Weather conditions and the activity of local pollinators can influence whether pollination is successful.
As the pumpkin grows, it begins as a green, immature fruit before developing its mature color. Inside, the seeds develop within the seed chamber, surrounded by the fleshy portion commonly used for cooking or removed during pumpkin carving.
Black also explains that different pumpkins have different characteristics. Traditional jack-o’-lantern pumpkins tend to have a more open seed chamber, while culinary pumpkins are often valued for their thicker flesh, which is useful for making pumpkin-based dishes.
The discussion also highlights Illinois’ connection to pumpkin production. Morton, Illinois, is known for its role in growing pumpkins for the canning industry, helping establish Illinois as a major center of pumpkin production.
The Surprising History of the Jack-o’-Lantern
With Halloween approaching, Black shifts the conversation from gardening basics to the folklore behind one of the season’s most familiar traditions.
The practice of carving jack-o’-lanterns originated in Ireland, where people carved faces into turnips rather than pumpkins. According to the tradition discussed in the episode, these frightening faces were intended to ward off evil spirits during Halloween, a time when folklore held that the boundary between the living and the spirit world became thinner.
People would hollow out turnips and carve faces into them, placing a glowing hot coal inside to illuminate the design. The practice eventually changed as Irish immigrants brought the tradition to America, where pumpkins were readily available.
Compared with the hard, solid turnips used in Ireland, pumpkins were much easier to hollow out and carve. Over time, the pumpkin jack-o’-lantern became the familiar Halloween decoration seen on porches and doorsteps today.
The conversation explores how cultural traditions evolve when people bring their customs to new places and adapt them to the resources available.
Celebrating Halloween Through Horticulture
Black shares how gardening and Halloween can come together through creative projects that go beyond traditional pumpkin carving.
In addition to carving pumpkins, he enjoys painting them and using them as decorative planters. One approach involves removing the top of a pumpkin, scooping out the interior, and planting flowers directly inside. Mums are a popular choice because they are readily available during the fall and complement the rounded shape of the pumpkin.
Another option involves leaving the pumpkin intact and using small holes to arrange artificial or silk flowers. This creates a decorative centerpiece that can last longer than a traditional carved pumpkin.
Black also discusses an upcoming horticulture program focused on Halloween traditions, including an attempt to recreate the historical practice of carving turnips. The program is part of his monthly horticulture series, held on the third Tuesday of the month, with a November schedule adjustment to the second Tuesday. The sessions take place from 5:30 to 6:30 p.m. at the Sauk Valley Community College greenhouse.
The planned activity offers participants an opportunity to explore the history of jack-o’-lanterns while trying a traditional carving method that predates the modern pumpkin decoration.
Growing Curiosity Through Gardening
Throughout the episode, Long asks questions about pumpkin development, gardening challenges, and Halloween history, creating an accessible introduction to horticulture for viewers of all experience levels.
From understanding how flowers develop into pumpkins to learning why turnips once served as Halloween decorations, the conversation demonstrates how everyday seasonal traditions connect to science, history, and culture.
Black encourages viewers to keep learning about the plants and traditions around them, noting that horticulture can offer surprising discoveries and useful conversation starters, especially during the Halloween season.
