Click on links below to jump to that question.
I have planted my first garden and am thinking about growing potatoes, but I don’t know how much to water them if I do plant. I live in South Carolina and it’s very hot here. I have mostly sand for soil. However, I have bought soil and mixed it in. Please let me know how much to water and any other tips you may have.
For the maximum crop, keep your potato vines well watered throughout the summer, but especially during the period when they are in flower, and immediately thereafter. Keep soil moist but not soggy. Water early in the day so that the foliage has time to dry completely before evening. When foliage turns yellow and dies back, discontinue watering.
I have a question about my potatoes. I planted a light skinned, I believe it was Yukon Gold, potato. I have graveled a few and the skin is red. I am puzzled. Can you give me an answer?
If it is a blotchy red, it could be blight on the potatoes, but you would likely also see some unhealthiness in the foliage as well.
Another possibility is that the seed potatoes were mislabeled. The fungicide that was used to treat them may have masked the red color and had given them a lighter colored cast.
If you cut them back, you will be removing their ability to collect energy to store. Since they store excess energy in their tubers (aka potatoes) this means there would be fewer and smaller potatoes. It is best not to cut them back. Some people do mound up dirt or straw around the vines and this forces the plant to grow more tubers.
If you have not already done so, reading this article should help: https://www.gardeningknowhow.com/edible/vegetables/potato/how-and-when-to-harvest-potatoes.htm
