Japanese cucumbers (Cucumis sativus) create a long, delicious fruit that works well for cutting and eating fresh. The annual vine-producing plants grow vigorously and require plenty of distance from the garden to stop crowding since the vines can grow 8 feet tall. Understanding the size of the mature plants helps with garden organizing and making efficient use of space.
Japanese cucumbers are vine-growing varieties that need a trellis system for help. This type of cucumber includes a vigorous growth habit with varieties that could reach up to 8 feet tall. Assess the mature height of the plant to the seed container or package to allow for good distance in the lawn. Not all of cultivars will grow to the exact same height.
Japanese cucumbers make a very long, slender fruit that’s 1 to 2 inches in diameter. The cucumber span varies from a little 1 1/2 inches up to 18 inches long.
Space Japanese cucumbers 1 foot apart at planting when using a trellis for vertical growth. Plants left to grow naturally with no trellis demand a minimum distance of 4 feet to allow room for your vine spread.
