Cucumbers can be transplanted into your garden between April 1 and August 15. They would like to be planted into a richly composted soil and given three cups of both our Landscape Mix fertilizer and of worm castings. Cucumbers will be happier and will produce more harvestable fruit if they are trellised or somehow are kept off of the ground. Anything from a chain-link fence, to a wooden pole, to a tomato cage can be used to prop up your cucumbers. Water deeply, every five days during the summer and allow the soil to dry out between waterings.
