Cucumbers are a popular vegetable amongst home gardeners due to their clean, crisp and refreshing flavor. These vegetables can be grown throughout most of the United States, whether it be in the warm Southern states or the cooler climates of the North. Since the first step in growing cucumbers is seed germination, it's good to start the seeds indoors where you have more control over the environment, thus improving the germination rate.
Fill a planter with high-quality peat three to four weeks before the average date of the year's last frost. If you plant on growing more than one cucumber plant, use one planter for each plant you intend to grow.
Water the peat so it's thoroughly moist before you add the seeds.
Plant two or three evenly spaced seeds 1/2 inch deep in the peat per planter. It's best to plant a couple extra seeds as some may not germinate.
Put the planters in a sunny window. If the outside temperature is above freezing, you can put the planters outside in the sun during the day, but be sure to bring them back inside at night.
Keep the peat moist at all times. The seeds should germinate within seven to 14 days.
