It is CRUCIAL to keep your potatoes well watered, especially during the flowering stage and right after. 1-2 inches of water a week! When foliage turns yellow and starts to die back, discontinue watering.
After taking two hours to put my toddler down for a nap, I’m finally able to get this post out! She’s in the beginning stages of switching from a crib to a bed, so it’s been all sorts of fun. But I’ve been thinking about how wonderful spring is. Children are outside more, stretching their legs and running full speed on the play ground. It seems Mother Nature is cleaning the earth of the dark cold layers of snow and ice, with heavy rain falls interspersed with warm sunny days. Worms are making there way towards the surface and the flowers are starting to bloom. It’s just hard to be sad when the earth is so alive!
This past week we’ve been working really hard to expand our garden and get things planted. We should be about doubling the space, which will be especially nice since I’v been wanting to grow corn, potatoes, Hubbard squash and cantaloupe this year, and those things take up so much space! We put down probably about an inch of compost over the entire area along with some peat moss and vermiculite. We got our lettuces, spinach, kale, cilantro starts, and soon our beets, peas and carrots planted.
I also just got my *very first* shipment of potatoes today. I decided to grow La Ratte and Yellow Finn. They look beautiful, if you’re into tubers 😉 I set them out to get a bit of heat and light, so hopefully they will be ready to go into the ground in about a week or two.
Seed Savers has some great tips on growing potatoes! This was taken straight from their Blog and the flyer they sent me with my shipment:
TIPS FOR GROWING POTATOES
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 respectable 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 of potatoes. If you are new at growing potatoes, ask around; chances are there are many older gardeners in your area who have years of gardening experience.
Potatoes may be planted as soon as the ground can be worked in the early spring, but keep soil temperatures in mind. 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. Plant smaller potatoes whole. A good rule of thumb is to plant potatoes whole if they are smaller in size than a golf ball. In a day or so your seed will form a thick callous over the cuts, which will help prevent rotting.
Planting in the Garden
We find that potatoes are best grown in rows. 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. 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.
Keep your potato vines well watered throughout the summer, especially during the period when the plants are flowering and immediately following the flowering stage. During this flowering period the plants are creating their tubers and a steady water supply is crucial to good crop outcome. Potatoes do well with 1-2 inches of water or rain per week. When the foliage turns yellow and begins to die back, discontinue watering. This will help start curing the potatoes for harvest time.
Harvesting Your Potatoes
Baby potatoes typically can be harvested 2-3 weeks after the plants have finished flowering. Gently dig around the plants to remove potatoes for fresh eating, being careful not to be too intrusive. Try to remove the biggest new potatoes and leave the smaller ones in place so they can continue to grow. Only take what you need for immediate eating. Homegrown new potatoes are a luxury and should be used the same day that they are dug. Potatoes that are going to be kept for storage should not be dug until 2-3 weeks after the foliage dies back. Carefully dig potatoes with a sturdy fork and if the weather is dry, allow the potatoes to lay in the field, unwashed, for 2-3 days. This curing step allows the skins to mature and is essential for good storage. If the weather during harvest is wet and rainy, allow the potatoes to cure in a dry protected area like a garage or covered porch.
At Heritage Farm we are able to store potatoes well into the spring in our underground root cellar. Try to find a storage area that is well ventilated, dark, and cool. The ideal temperature is between 35 and 40 degrees F. Keep in mind that some varieties are better keepers than others. Varieties like Red Gold and Rose Gold are best used in the fall, and others like Carola and Russets are exceptional keepers.
Saving Seed Stock
Home gardeners can save seed for several generations. Save the very best potatoes for planting. You may find that after several years the size begins to decrease; this is typical. Potatoes are very susceptible to viruses. If you are looking for maximum yields it is best to start with fresh, USDA Certified Seed Stock every year.
Is anyone else growing tubers this year? What varieties are you growing?
