Delicious personal-size kabocha.

Cute, sea-green squash sized perfectly for single servings, soup bowls, and more, with little to no wasted fruit. Great for small families and singles. With heavy yields and exceptional storage, Sweet Jade will be the next market grower and CSA favorite. Fruits are about twice the size of the Shokichi series, with very few culls. Bred by Dr. Lindsay Wyatt at Johnny’s. Avg. weight: 1–2 lb. AAS winner. USDA Certified Organic.

SCIENTIFIC NAME

Cucurbita Maxima

CULTURE

Fertile, well-drained soil with a pH of 6.0–6.8 is best. Plastic mulch and fabric row covers (AG-19 grade) can aide plant establishment and exclude insect pests during the seedling stage. Row covers should be removed when plants begin to flower. Poor fruit development may indicate insufficient pollination.

TRANSPLANTING

Sow 2-3 seeds per 2" container or plug flat about 3 weeks prior to transplanting. Thin to 1 plant/container or cell with scissors. Harden plants 4–7 days prior to transplanting. After danger of frost has passed, transplant out according to the spacing recommendations for each variety. Handle seedlings carefully; minimal root disturbance is best.

DIRECT SEEDING

Sow 2 seeds at the appropriate spacing interval for the variety's vine length, 1/2-1" deep. Thin to 1 plant per spacing interval after seedlings are established.

PLANT SPACING

Bush to short-vine habits generally require 6' between-row spacing, while long-vine habits require 12' between-row spacing. In-row spacing depends on fruit size and is generally: small, 18-24"; medium, 24-36"; large, 36-48".

DISEASES

Common cucurbit diseases include powdery mildew, downy mildew, bacterial wilt, and Phytophthora. Avoid problems with adequate soil drainage, good air flow, insect pest control, and crop rotation. If necessary, check with your local Cooperative Extension Service agent for specific control options.

INSECT PESTS

Cucumber beetles, squash bugs, and vine borers are all common pests for cucurbits. Protect young plants with floating row cover. Squash bug eggs found on the undersides of leaves may be crushed by hand. For vine borers, cut out of vines and hill soil over the wound. Keep field borders mowed and remove plant refuse in the fall; spring plow to bury pupae. Pyrethrin sprays may offer some control.

HARVEST

Fruits are typically ready about 50-55 days after fruit set, and should be harvested before any hard frosts. Cut fruits from vines and handle carefully. Sun cure by exposing fruits for 5-7 days or cure indoors by keeping squash at 80-85°F/27-29°C with good air ventilation.

STORAGE

Store at 50-60°F/10-15°C, 50-70% relative humidity and good ventilation. Repeated exposure to temperatures below 50°F/10°C may cause chilling damage. Kabochas get sweeter with a few weeks of storage. Green varieties will keep up to 4–5 months in storage; Winter Sweet will keep up to 6 months. Sunshine is the exception and is delicious right out of the field, but will only last a maximum of 3 months.

DAYS TO MATURITY

From direct seeding; subtract about 14 days if transplanting.
