Yellow Of Paris Pumpkin Seeds | 5 Seeds | Giant DE PARIS | USA 

The Yellow of Paris Pumpkin is a large yellow to peach colored pumpkin that is an old French native that is still popular today. These large, flattened round beauties are very similar to Cinderella pumpkins and can weigh up to 50 pounds! This variety is mainly used for making pies, soup or baked.

Pumpkins can be grown for decorative and edible purposes, with different varieties grown to make pumpkin pie, carving for Halloween, to be used in canning and more. Pumpkins range in sizes from small, gourd-like varieties to large options and differ in color and outside texture as well.

Before Planting: Pumpkins like fertile, well-drained soil with a pH of 6-6.5. Row covers can protect seedlings for several weeks. Row covers should be removed when plants begin to flower. Time plantings so that varieties will mature for the fall market. Planting too early can lead to dead foliage and over exposure to sun.

Planting: Direct seeding is the easiest and most successful method of planting. Sow in late spring when soil is at least 70°F and danger of frost has passed. Sow 2 seeds at the appropriate spacing interval for the variety’s vine length, 1? deep. Thin to 1 plant per spacing interval after seedlings are established. For transplanting, sow 2-3 seeds per 2? container or plug flat about 3 weeks prior to transplanting. Transplant should be no older than 3 weeks as stunting and damage can happen.  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. Bush to short-vine habits generally require 6? between-row spacing, while long-vine habits generally require 10-12? between-row spacing. In-row spacing varies depending on fruit size and is generally: small, 18-24?; medium, 24-36? and large to extra-large, 36-72?. Spacing requirements may vary, so check under characteristics for each variety.
