Dill’s Atlantic Giant Pumpkin, ecologically grown seeds(Cucurbita maxima)

Product code : GAIAS-0300

Dill’s ‘Atlantic Giant’ pumpkin is a Canadian open-pollinated heritage variety, developed by Howard Dill to produce exceptionally large fruits. In specialized cultivation, a single fruit can reach several hundred kilograms, but results depend heavily on the season, soil, and care. The packet contains 5 organic seeds. Gaia indicates a maturity of approximately 110 days and vines that can reach 15 m. This annual plant requires full sun, very fertile soil, consistent moisture, and considerable space. To aim for a giant fruit, keep only one promising fruit per plant after good fruit set and support it on a clean, dry surface.

Dill’s Atlantic Giant Pumpkin, ecologically grown seeds (Cucurbita maxima) This open-pollinated heirloom was developed in eastern Canada by Howard Dill for giant-pumpkin growing. Under specialized care, fruit may reach several hundred kilograms, although weight varies enormously with warmth, fertility, space, water, and fruit selection. The packet contains 5 ecologically grown seeds; Gaia does not present them as certified organic. The annual plant develops extremely vigorous vines that may reach approximately 50 feet. It suits large gardens and competition projects, not small beds or ordinary containers. Home-grown pumpkins are often far smaller than record-class examples.

Start seed indoors three to four weeks before the last frost in large individual pots, or direct sow after frost danger has passed and the soil is warm. Plant approximately 1 inch deep. Germination generally takes 7 to 10 days at 27 to 35°C. Soaking and scarification are not required. Harden plants carefully before setting them in full sun and deep, highly fertile, well-drained soil. Allow approximately 15 to 20 feet between plants and the same between rows. Water deeply at the base and protect bee access to flowers. Maintain consistent moisture as fruit expands rapidly.

Gaia lists approximately 110 days to maturity. To pursue one giant fruit, allow several fruit to set, select the strongest, then remove competitors gradually. Place a board or dry sand beneath the pumpkin, keep the stem relaxed, and avoid moving long vines. Harvest before a hard frost after colour develops and the stem becomes corky. Cut while retaining at least 4 inches of stem and use several people or suitable equipment to move a large fruit; never lift it by the handle. Fruit not intended for competition is edible, although culinary quality is secondary to size potential. Inspect the rind before cooking any portion.

How to use it

Uses in the garden

Reserve an entire plot for Dill's 'Atlantic Giant'. One plant can extend its vines up to approximately 15 m and requires 4.5 to 6 m of space in all directions. Orient the vines away from pathways, fragile fences, and low-growing crops. Mulch applied after the soil warms helps stabilize moisture. Place a thick board, a layer of dry sand, or a pumpkin support under the developing fruit. Allow enough slack in the stem as the fruit grows. Keep flowers accessible to pollinators and avoid insecticide treatments on open blossoms. Read the package directions before starting and keep the label to track the variety throughout the season. Prepare a clean, loose, and well-drained growing medium, then moisten it before placing the seeds to limit their displacement. Keep the seedlings evenly moist without standing water, as excess moisture reduces aeration around young roots. Place seedlings in bright light as soon as they emerge and rotate containers regularly to promote balanced growth. When multiple seedlings compete for the same space, carefully thin to retain the most vigorous specimens without disturbing their roots.

Frequently asked questions

01 How much does the sachet contain?
The packet contains 5 seeds. Read the instructions on the packet before starting and keep the label to track the variety throughout the season. Prepare a clean, loose, and well-drained substrate, then moisten it before placing the seeds to limit their movement. Keep the seedlings uniformly moist without allowing standing water, as excess moisture reduces aeration around young roots. Place the seedlings in bright light as soon as they emerge and regularly rotate the containers to promote balanced growth. When multiple seedlings compete for the same space, carefully thin them to keep the most vigorous specimens without disturbing their roots.
02 How to start the seedling?
Start one seed per large pot 2.5 cm deep three to four weeks before the last frost, or direct sow when the soil is warm and the risk of frost is over. Germination takes 7–10 days at 27–35 °C. No soaking or scarification is needed. Keep the substrate moist but not soggy, provide bright light after emergence, and harden off seedlings before transplanting. Allow 4.5–6 m between plants and rows for stems that can reach 15 m.
03 How long does germination take?
Germination generally takes 7 to 10 days when the substrate remains between 27 and 35°C. Sow 2.5 cm deep and keep the soil evenly moist, without standing water. No soaking or scarification is necessary. Cold soil slows emergence and increases the risk of rot. Once seedlings appear, provide bright light and allow the surface to dry slightly between waterings. Handle roots as little as possible when transplanting and use a pot large enough to limit tangling. Read the packet instructions before starting and keep the label to track the variety throughout the season.
04 How to organize garden planting?
Reserve a whole plot and leave 4.5 to 6 m between plants and rows. Full sun, deep soil richly amended with compost, and regular watering at the base are essential. No particular companion plants are needed, as the stems can reach 15m and cover nearby crops. Keep the flowers accessible to bees, direct the stems to a free area, and rotate with plants from other families. For a giant fruit, choose a well-positioned fruit, support it on a dry surface, and gradually remove competing fruits after good fruit set. Read the package directions before starting and keep the label to track the variety throughout the season.
05 When should we harvest?
Harvest after about 110 days and before a hard frost, when the color has developed and the stem becomes corky. Cut, leaving at least 10 cm of stem, and never lift the fruit by its stem. For very heavy pumpkins, prepare a clear path, use straps or a lifting tarp, and gather enough people or suitable equipment. Move the fruit slowly to avoid injury and cracks. If the pumpkin is intended for a competition, consult the weighing and transport rules before harvesting. Read the packet instructions before starting and keep the label to track the variety throughout the season.
