Fill the seed tray pots with potting soil using a hand spade. Gently press down on the soil so it is firmly but not tightly packed.
Place one Marketmore 76 seed in each seed pot. Sprinkle 1/4 inch of potting soil over the seeds.
Water the seed tray pots until the soil is damp but not soaking wet. Cover the seed tray pots with the seed tray cover and set in a sunny location. The seeds germinate and sprout within seven days.
Remove the seed tray cover when the seeds have sprouted. Water the seedlings on a regular basis until they are 2 to 4 inches high.
Place the seed tray outdoors in a sunny location during the day and return it indoors in the evening. Do this every day there is not inclement weather for one week. This process is called hardening.
Plot out the location for each seedling. Seedlings need a minimum of six inches between each plant.
Dig a 3-inch-deep hole for each seedling using the hand spade. Gently remove each cucumber seedling from its seed pot and transfer into the hole. Do not disturb the root structure. Brush the soil back into the hole around the seedling. Gently press down on the soil around the seedling so that the seedling is firmly in place.
Push in one vegetable cage around each cucumber seedling. The bottom of the cage should sit 6 inches underground and be sturdily supported so it does not tip over very easily. The cucumber seedling should be at the center of the cage. Water each seedling using the watering can after putting in the cage.
Cut pieces of nylon rope into 3-inch segments using scissors. Gently tie the cucumber vine to the side of the vegetable cage. Do not tie too tightly as this chokes the cucumber plant.
Wrap the cucumber vine around the vegetable cage as it grows. Use nylon rope to secure or provide additional support to the vine as the plant grows. Water the cucumber plant daily, either early in the morning or just before sunset.
