Pacific Giant Pumpkin (Cucurbita maxima) 10 Seeds Per Pack

Grow a field that’s filled with Pacific Giant Pumpkins, from freshly harvested Cucurbita maxima seeds. Pacific Giant is an amateur variety that is fairly easy to establish. The fruits grow to enormous sizes of over 350 pounds and display a pale orange skin, with deep orange innards. The vines can reach lengths of 25 feet long, and can grow to a height of about 2 feet tall. Pacific Giant Pumpkins are ready for harvest in about 125 days after first sprouts appear.

Pumpkins thrive in the heat of summer and are grown as annual fruits. Annual crops will produce flowers and fruits within a single season. If the seeds are collected from the inside of the pumpkins, they can be regrown the following year. Pacific Giant Pumpkins are primarily grown and entered in many contests to see who can grow the largest pumpkin.

Sowing The Seed

Pumpkins are best established directly outdoors in the summer. Be sure to select a large enough area for the plants to grow and vine outwards. Remove all unwanted plant life from your sowing area, turning the dirt, or replacing the dirt with a fresh soil. Create mounds of dirt or “hills” roughly 18 to 24 inches wide and at least 8 inches high. Sow 4 seeds per mound at a depth of 1.5 inch under topsoil. (See “Germination & Growth” for spacing and other growth habits)

Growing Conditions

Pumpkins enjoy the heat of summer and will thrive in temperatures that are above 75F. The soil should be rich in organic matter, but will also need to be well drained. To improve drainage, it is recommended to add a light compost to any hard, compacted soil in the sowing area. This will prevent the roots from rotting. Water the seeds daily with a mild setting so that the seeds and seedlings are kept moist until germination occurs.

Germination & Growth

Pacific Giant Pumpkin seeds will begin to sprout open in roughly 7 to 14 days after sowing. The plants will grow to a mature height of 1 to 2 feet tall and 20 to 25 feet long. These plants will need a large area to grow outwards and can be spaced by hills or mounds of dirt, rather than rows. As explained above mounds should be 18 to 24 inches wide and at least 8 inches tall. Space each mound at least 6 to 8 feet apart from one another. When sprouts become visible, direct the vines outwards towards areas that do not contain other plant life.

Harvesting Pacific Giant Pumpkins

When your vines start to establish pumpkins, be sure to place straw under the fruits to prevent them from touching the bare ground beneath, as this will prevent rotting. Your Pacific Giant Pumpkins will be ready for harvest in roughly 125 days after first sprouts appear. Harvest by cutting the stems at least 2 to 3 inches from the actual fruits, otherwise the fruits will rot.
