Cucumber Seeds

When to Plant Cucumber Seeds

Cucumbers should be directly sown three to four weeks after the last frost in the spring. They can be started indoors four to six weeks before your last frost using a grow light and seed starting soil mix.

Where to Plant Cucumber Seeds

Plant cucumbers in an area that receives full sun in rich, well-draining soil.

How to Plant Cucumber Seeds

You can amend your soil with compost or aged manure prior to planting, preferably in the fall so it will over-winter. Plant a half inch deep and about 12 inches apart. Alternatively, you can create hills four to six feet apart, with six to eight seeds per hill. Cut the three weakest plants once seedling emerge for this method. Make sure to keep soil moist, avoid letting the soil dry out completely. Germination generally takes around 10 days when temperatures are about 70 degrees. Cucumbers are vine plants, so setting up a trellis may be beneficial depending on your garden.

How to Harvest Cucumbers

Harvest cucumbers before they are fully mature, as cucumbers tend to get seedy once they’re at their largest. They grow very fast, so be sure to check often to see if it’s time to harvest. Make sure to cut them off the vine, as pulling them off can damage or break the vine and prevent further production.
