POTATO GROWING GUIDE
      Potatoes always do best in full sun. They are aggressively rooting plants, and we find that they will produce the best crop when planted in a light, loose, well-drained soil. Potatoes prefer a slightly acid soil with a PH of 5.0 to 7.0. Fortunately potatoes are very adaptable and will almost always produce a decent crop, even when the soil conditions and growing seasons are less than perfect. Always keep your potato patch weed-free for best results. Potatoes should be rotated in the garden, never being grown in the same spot until there has been a 3-4 year absence.

Planting Times

Potatoes may be planted as soon as the ground can be worked in the early spring. Potato plants will not begin to grow until the soil temperature has reached 45 degrees F. The soil should be moist, but not water-logged. Potatoes can tolerate a light frost, but you should provide some frost protection for the plants if you know that a hard, late season freeze is coming. If you want to extend storage times, and have a long growing season, you can plant a second crop as late as June 15 and harvest the potatoes as late as possible.

Cutting Potatoes Before Planting

A week or two before your planting date, set your seed potatoes in an area where they will be exposed to light and temperatures between 60-70 degrees F. This will begin the sprouting process. A day or two before planting, use a sharp, clean knife to slice the larger seed potatoes into smaller pieces. Each piece should be approximately 2 inches square, and must contain at least 1 or 2 eyes or buds. Smaller potatoes planted whole, a good rule of thumb is to plant them whole if they are smaller in size than a golf ball. In the next day or so, your seed will form a thick callous over the cuts, which will help to prevent it from rotting once planted.

Planting in the Garden

We find that potatoes are best grown in rows, or even better, aeration pots like Smart Pots. To begin with, dig a trench that is 6-8 inches deep. Plant each piece of potato (cut side down, with the eyes pointing up) every 12-15 inches, with the rows spaced 3 feet apart or closer if in pots. If your space is limited or if you would like to grow only baby potatoes, you can decrease the spacing between plants. To begin with only fill the trench in with 4 inches of soil. Let the plants start to grow and then continue to fill in the trench and even mound the soil around the plants as they continue to grow. Prior to planting, always make sure to cultivate the soil one last time. This will remove any weeds and will loosen the soil and allow the plants to become established more quickly.
