Cucumber planting guide:
To sow cucumber seeds in a container, plant three seeds from a seed packet per pot
Push them into the soil about a half inch down into the potting mix.
Water thoroughly and keep the garden soil perpetually moist until the seed
s germinate.
Depending on the cucumber variety, and the size of the container, you should consider repotting two out of the three plants in your container so that they have enough room to grow.
When to Plant Cucumbers?
When growing cucumbers, you want to be mindful not to plant them too soon; they are very sensitive plants, and they will not fare well in weather that drops below 70°F. Do not move them to your outdoor container garden any earlier than 2 weeks after the last spring frost.
If you are growing in a sunny and hot climate like Texas, you’ll want to make sure to plant just after the last spring frost and before the sunshine becomes too scalding. If you are growing in a cooler and less sunny climate, plant your cukes when you are certain that they will receive at least 5 hours of full sun every day.
