Planting Instructions:


Soil Preparation:

Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade the soil 8-12 inches deep and turn each shovel of soil over completely to cover the plant materials with soil. You may add fertilizer or organic matter at this point (see "Fertilizing" below). Make rows of soil beds 4-6 inches high and at least 3 feet apart. This formation of ridges will help with drainage, which is essential for cucumbers.


Since cucumbers cannot survive frost, plant only after all danger of frost has passed and the soil begins to warm. Choose an area with full sunlight, well-drained soil, and away from tree roots. To plant, make 1 inch deep holes spaced 12-14 inches apart in raised beds down the rows, then plant 3-4 cucumber seeds in each hole. Cover seeds with about 1 inch of fine soil and firm the soil with the flat side of a hoe, but do not pack it. By planting several seeds, you are more likely to get a stand. Remove extra plants after seedlings emerge.

Cucumber vines can reach 6-8 feet long or more and require lots of space. In large gardens, cucumbers can be spread on the ground. In small gardens, cucumbers can be trained on a fence, trellis, cage, or along a wire attached to a wall. If wire cages are used, plant along the cage or trellis. *Tip: You can plant fast maturing crops such as lettuce and radishes between cucumber hills to save space. These will be harvested before the cucumber vines get too large.

Planting Depth: 1 inch
Within-Row Spacing:
12-14 inches, thin
Between-Row Spacing:
3-5 feet


Care During the Season:

Watering: Water the plants well about once a week if it does not rain.

Weeding: Keep cucumbers plants as weed-free as possible. When plowing or hoeing do not dig deeper than 1 inch to prevent from cutting the feeder rooters which may slow the plant's growth.

Fertilizing: Cucumbers require plenty of fertilizer, scatter 1 cup of a complete fertilizer for each 10 feet of row. Work into the soil and leave the surface smooth. When vines are 10-12 inches long, you may optionally apply 1/2 cup of fertilizer for each 10 feet of row, or 1 tablespoon per plant. Water the plants after fertilizing.

Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options. Sulfur also has fungicidal properties and helps in controlling many diseases. Before using a pesticide, read the label and always follow cautions, warnings and directions.

Diseases: Diseases can show up as spots on the upper or lower sides of leaves or cucumbers. Check the plants daily and if these spots appear, treat the plant with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. Please always follow label directions.


Harvest Japanese Long cucumbers when reach the desired size and are deep green in color. These cucumbers are best picked when they are 12 inches long and mature. Try not to wait until cucumbers turn pale because they will be over-mature and have a strong flavor.
