snow_lady [41]

Answer:

Explanation:

Growing Peas

Planting depth should be roughly 2 inches with a spacing of about 2 inches apart. Water well at planting and provide at least 1 inch of water per week, particularly during the flowering and pod production stages. As the temperature rises, the vines may need to be deeply watered almost every day.

Make sure to moniter it and change the water depending on how dry or overwatered it looks like. :)
