Growing cucumbers in containers can be challenging, as their long vines can become hard to manage. Cucumbers love heat. Temperatures must be over 70 degrees F consistently for germination to occur. Avoid sowing seeds until the optimal temperature condition is achieved. According to Ohio State University, some cucumber varieties may do better in containers: these include Salad Bush Hybrid, Bush Champion, Picklebush, Spacemaster, Hybrid Bush Crop and Midget Bush Pickler.
Select a 12-inch or larger container to use for planting your cucumber seeds. Place 1 inch of gravel in the bottom to assist with drainage. Fill the rest of the container with potting soil.
Dig a small hole about a 1/2 inch deep in the middle of the soil. Place five to six seeds in the middle of the hole and lightly place soil back over the seeds.
Set the container in a sunny location.
Thin seedlings when there are two sets of leaves. Choose the two strongest seedlings and thin the rest. Use a pair of sharp scissors to cut the weaker seedlings at the soil line. After plants are 8 to 10 inches tall, cut off one plant to leave only one growing in the container.
Fertilize the plant daily with a 10-20-10 or 12-24-12 formula. Mix the fertilizer with water per the instructions until the fertilizer is dissolved. Water the plant daily with the fertilizer solution unless it rains. Water the soil until it appears evenly moist.
Place a 4-foot trellis behind the container for the plant to grow on. Trellising maximizes space and protects fruit from animals, disease and pests.
