Should I Prune My Cucumber Vine – Tips On Pruning Cucumbers In The Garden

By: Amy Grant

Healthy cucumber plants can get downright out of hand with their rampant vining growth. I’m not complaining, I get lots of fruit, but it made me wonder if I should prune my cucumber vines. Maybe you, too, are wondering if it’s okay to prune cucumbers. Here’s what I found out about trimming cucumber vines.

Should I Prune my Cucumber Vine?

The short answer is yes, it’s okay to prune cucumbers, but I guess that doesn’t really say much. Both cucumbers’ vegetative and reproductive growth need to be balanced. Anyone who’s ever looked at a cucumber plant can see that it is often the vegetative growth that’s left to run amok. So cucumber vine pruning is a way to check that growth and stimulate reproduction, or fruiting.

About Cucumber Vine Pruning

Cucumber vines generate from a single stem and produce multiple shoots. Pruning cucumbers helps maintain the balance between vine growth and fruit production. Prune outside branches, leaves, flowers and fruit as needed throughout the growing season.

Begin trimming cucumber vines by removing any dead or damaged portions. Remove older leaves to allow light to reach developing fruit and improve air circulation.

Trim off all shoots that branch from the main vine stem. Starting at the beginning of the shoot, make a cut as close to the main stem as possible.

Lateral shoots, flowers and fruit that develop on the lower 5-7 leaf nodes should be removed. This is especially important on seedless greenhouse-types of cucumbers, as they can support only one fruit per leaf node. If more than one fruit develops, remove it. Cultivars that produce smaller and seeded fruit can be allowed to have more than one fruit per node so additional fruit does not need to be removed. Otherwise, using sharp pruning shears, remove all fruit except one per leaf.

Also, remove the first 4-6 lateral runners that appear. Removing these lateral runners near the base of the plant will gain higher yields. Other runners above the base of the plant can be allowed to remain.

Crossvine Plant Propagation

If you’re thinking of growing crossvines from a mother plant, there are two ways to approach propagation — from seeds or cuttings.

Seeds are ready to harvest in late summer or fall when they turn light brown. Crossvine seeds have a woody texture. No treatment is required before planting.

Plant seeds in a well-draining planter, add peat, perlite or coarse sand to improve drainage. Plant 1-2 inches below the surface and keep the soil moist. In about 3 weeks the seeds should germinate.

If you go with the stem cutting method, choose a 6 to 8 inch section from a growing stem. Harvest cuttings in spring.

Remove any leaves from the bottom, wound the base of the stem (2 small incisions on opposite sides should do the trick). Treat the wounded area with rooting hormone to stimulate growth.

You can use the same type of growing medium you use for germinating seeds. Plant 2-3 inches deep. Keep the growing medium moist.
