1 - Overview
‘Jack be Little’ is a miniature Cucurbita pepo pumpkin, also known as squash ‘Jack be Little’. It produces some of the smallest pumpkins: attractively ribbed, round, flattened and roughly palm-sized, with bright-orange skin. Their individual-portion scale makes them ideal for stuffing and baking whole, and they can also be made into miniature Halloween lanterns.
One plant can produce around ten fruits. When they are allowed to ripen fully and are harvested and cured without damage, the pumpkins may store for up to twelve months. The combination of high fruit count, unusually small size and exceptional storage potential clearly separates this cultivar from large carving and competition pumpkins.
2 - Size
- Ultimate height
- 0.1–0.5 metre
- Ultimate spread
- 1–1.5 metres
- Time to maturity
- one year
- Fruit size
- roughly palm-sized
- Typical yield
- around ten fruits per plant
- Habit
- trailing
The vine is compact by pumpkin standards but still needs room to trail. Its light fruits can be grown above ground on a sturdy teepee or trellis, saving bed space, or the stems can be directed in a circle. Check ties and supports as the crop develops even though each fruit remains small.
3 - Growing conditions
- Suitable soils
- Loam or sand
- Moisture
- Moist but well drained, or well drained
- Preferred pH
- Acid or neutral
Grow in fertile, moisture-retentive but freely drained soil enriched with organic matter. Consistent watering supports the relatively large number of developing pumpkins. Mulch after the ground has warmed, keeping the main stem clear, and apply a high-potassium fertiliser regularly once the first fruits begin to swell.
Its modest spread and light crop make ‘Jack be Little’ suitable for a large patio pot or grow bag, but container compost dries quickly. Use a container at least 45cm wide, water deeply and feed throughout fruit development.
4 - Position and hardiness
- Light
- Full sun
- Aspect
- South- or west-facing
- Exposure
- Sheltered
- Hardiness
- H2
Choose a warm, sunny site protected from cold winds. The cultivar tolerates low temperatures only above freezing and must not be exposed to frost. Raise seedlings under cover and plant outside after local frost risk has passed and the soil is warm.
5 - Colour and seasonal interest
Trailing stems carry green palmately lobed leaves and golden-yellow flowers before the miniature autumn crop develops. Each ripe pumpkin is bright orange, deeply and neatly ribbed, round but distinctly flattened from top to base, with a short intact stalk. A representative plate should show several whole palm-sized fruits clustered around restrained foliage, making their small scale and abundant yield unmistakable. One halved fruit may reveal orange flesh and a small seed cavity.

Genus
Cucurbita is a small genus of climbing and trailing annual plants native to Central and South America. Cultivated members have broad, prickly, palmately lobed leaves, separate golden-yellow flowers and fleshy fruits grown for food and decoration.
Safety
Do not eat or give pets any pumpkin that tastes unusually bitter. Bitterness may indicate harmful cucurbitacins. Discard the fruit and remove the plant, and use gloves if rough stems or leaves irritate the skin.
7 - How to grow
Cultivation
Sow indoors from March to May in good-quality seed compost. Place one seed on its side about 1cm deep and maintain a constant 18–21°C. Move seedlings into bright light, harden them off gradually and plant outside after the final frost into fertile, well-drained soil in full sun.
Water deeply at root level and feed regularly with a high-potassium fertiliser once fruits swell. Train the light-fruited vines around a bed or onto a strong support, keeping every pumpkin comfortably supported. If grown on the ground, place dry material beneath fruits so their skins remain sound.
Harvest before frost when the bright-orange skin is hard, cutting with at least 10cm of stalk. Cure in a dry sunny place for seven to ten days. Store unblemished fruits separately in a well-ventilated place at about 10–15°C and inspect regularly; fully ripe specimens may keep for as long as twelve months.
Propagation
Propagate by seed, retaining one strong seedling per final position.
Suggested locations
- Patio container or grow bag
- Small allotment or vegetable bed
- Sturdy teepee or trellis
- Productive wildlife garden
Pruning
No pruning is required. Remove damaged foliage or unwanted late fruits cleanly, while retaining enough healthy leaves to ripen the numerous miniature pumpkins.
Pests
The profile records the cultivar as generally pest-free. Protect seedlings from slugs and snails and inspect fruits where they touch supports or soil.
Diseases
May be susceptible to grey mould and powdery mildew. Water at soil level, maintain air movement and remove damaged or decaying growth promptly.
