Cucumbers are very-tender vegetables that grow best in warm weather.
Plant seeds directly in the garden 2-4 weeks after the spring frost date.
To harvest sooner, start seeds indoors the week of the spring frost date, or purchase transplants. Transplants are ready when they have 2-3 true leaves. Harden off and transplant into the garden 2-4 weeks after the spring frost date.
Cucumbers take up a lot of space unless you use a trellis or vertical support, Remove misshapen fruit when it is small, since the shape will not improve as it gets bigger.
Cucumbers require high temperatures and many hours of sunlight. They cannot be grown in the winter.
Soil and Fertilizer
Cucumbers grow best in a rich soil; amend with lots of compost and fertilizer (chemical or organic) at planting and once during the season.
Fertilizer: Apply 16-16-8 at planting, 21-0-0 after 6 weeks.
Harvest slicing cucumbers as soon as they are large enough to be useful. Harvest pickling cucumbers when they are small and crisp. For both types, harvest every 3 days to encourage fruit production.
