Harvesting Potatoes
The potatoes that we planted in the fall were ready for harvesting this weekend. Fresh potatoes have a wonderful, snappy texture and flavor that I have never found in storebought potatoes. They are such an easy and rewarding crop to grow. Here in the south, we plant our seed potatoes in November in raised beds that are rich in compost and healthy organic matter. Check with your local extension office to determine the best time to plant in your zone. Once the vines grow a few inches, we give them a good 4-6 inches of mulch to keep them cool and protect them from the sun. Other than that, regular watering is about all that is needed to encourage potatoes to grow strong and healthy. An occasional, maybe monthly, feeding with compost tea or manure tea helps, too. We use Moo Poo tea, as it is natural, easy to use, and good for the soil.
How does one know when to harvest potatoes? Well, the plants tell you. As long as the potato vines look healthy and green, the potatoes are still growing deep in the soil. During this time, you may harvest baby “new” potatoes if you would like. This year, I left all of my potatoes in the ground for a main harvest. Potatoes take about 120 days to fully mature, depending upon the growing environment, weather, watering practices, and other elements. Once the vines begin to flower, the tubers underneath the soil begin to swell. Shortly thereafter, the vines will slow down, and begin to turn yellow and brown and fall over. They don’t look nearly so pretty. This is natural, and a sign that the taters are ready. Hallelujah!
Several days before you plan to harvest, discontinue watering the potato bed. This is a big help in harvesting, as it’s much easier to dig through light, dry soil than through heavy, muddy soil. To begin the harvest, remove any mulch, and pull up all the potato stalks. They are great to add to your compost pile. Then, the fun begins. Most people use a flat tined fork or pitchfork to harvest potatoes, but because I plant a small crop in raised beds, I start the treasure hunt for those beautiful tubers by putting some gloves on and searching through the soil by hand. This does take a little more time, but I enjoy the hunt, and it has a major advantage in that my gentle hands won’t damage the delicate skins of the tubers. If the skin is damaged, the potato will not store well.
Once I have worked my way methodically through the entire bed and found all the potatoes I can, I go back through it again with a pitchfork, slowly and methodically. I dig section by section, getting the pitchfork as deeply as possible into the soil, carefully turning it over, and piling it on the previous section. This process serves two functions. First, I find the rest of the potatoes that are deep within the bed, and second, I begin to prepare the soil for a new crop by removing any debris and weeds and turning over the soil. Once I have removed every last potato, I finish preparing the soil by adding compost and organic starter fertilizer, turning it into the soil, and smoothing out the bed. Now the bed is ready for a new crop.
Storing Potatoes
Once you have harvested all your gorgeous, fat tubers, you will probably want to celebrate and enjoy some of your harvest immediately. I always do, and last night I made a lovely leek and potato soup, rich with home-cured pancetta, cream and fresh thyme from the garden. I made enough to freeze a batch for later, too. The remainder of the crop should be cured for storage. Gently wipe off most of the remaining soil, and spread the taters out in a cool, dark and dry area that has good ventilation. Examine the tubers for any damage, as damaged ones will not store well. I don’t throw these away, but I do cut away any damage and use them immediately (I used these for my soup). Unblemished potatoes should be cured for a few weeks, and then stored in well, ventilated sacks in a cool, dark place. Properly cured, they will store well for months. It is not recommended to store potatoes in the refrigerator, as the cool temperature encourages the starch to turn into sugar. However, that’s where I store mine, as we don’t grow enough to store for longer than a few months.
Just-Harvested Potatoes and Leeks
Leek and Potato Soup with Pancetta
Ingredients
3 tablespoons butter
1/2 cup of diced pancetta or bacon
4-6 leeks (white and pale green parts only), halved lengthwise, thinly sliced (about 4 1/2 cups)
2-3 large potatoes peeled and diced
4 1/2 cups (or more) organic chicken stock
1-2 cups half and half
3-4 sprigs of fresh thyme
2 tablespoons chopped fresh chives (for garnish)
Preparation
Melt butter in heavy large saucepan over medium heat. Add pancetta and cook until beginning to crisp. Add leeks; stir to coat with butter. Cover saucepan; cook until leeks are tender, stirring often, about 10 minutes. Add diced potatoes. Cover and cook until potatoes begin to soften but do not brown, stirring often, about 10 minutes. Add chicken stock and bring to a boil. Turn the heat down to a simmer. Cover and simmer until vegetables are very tender, about 20 minutes. Add cream and thyme, and simmer for an additional 10 minutes. Remove thyme sprigs (the leaves will have fallen off ).
Using an immersion blender, puree the soup until smooth and silky in texture. Or transfer the soup in batches to a blender to puree. Thin with additional stock if soup is too thick. Season with salt and pepper. (Can be prepared 1 day ahead. Cover and refrigerate.) Bring soup to simmer. Ladle into bowls. Garnish with chives and serve.
Whoops we planted on mothers day. The potato plants look healthy but will we get potatoes? Obviously our first try at this.
Norma, it really depends upon where you live. If you are up north, you’re probably fine! I’m in north Florida, so we plant really early. Good luck with your potatoes!
I had bought potatoes that sprouted in my pantry. I cut them apart and planted them in my flower bed. The plants are huge and blooming. I grew up on a farm and used to love helping dig potatoes. Watching them grow is so much fun. Thanks!
Thank you, Carolyn, although my sister brought over a red bliss that has sprouts all over it, which she had forgotten she bought several months ago. We’re going to plant it anyway lol Will get seed potatoes also.
Plant away! Let me know if it works. It sounds like it will!
I’m so glad I found your blog via Twitter. That said, about 2 years agoo, my father planted a sprouted Yukon Gold potato, I think it was in the winter, and come summer or fall, he pulled at a few plants he thought were weeds, and discovered over a pound of big, beautiful Yukon Golds underneath. He kept digging and they kept popping up, Is it really this easy to get a crop of potatoes? I was thinking of doing it myself, but I’ve been using up my purchased potatoes too quickly for any to sprout enough to try it.
Welcome to Cowlick, Lisa! I’m glad you found us, too. Potatoes are pretty simple to grow, but I’d recommend that you get seed potatoes at your local nursery. Most potatoes sold in grocery stores today are treated to keep them from sprouting.
I love your description of digging the potatoes. I live not far from you and friends taught me to can potatoes from my crop. I will leave some fresh and store them, but have canned several quarts to use later in the year. Couldn’t wait to try a quart and they were delicious with cubed steak and carrots!
Look at those potatoes! Look at that soil too. I will be depending on you to remind me in November what I have to do again, to have great potatoes.
Great soup! Love it.

P.S. My garden is doing pretty good. I am hoping for at least a small harvest in late summer.
I’m glad to hear your garden is doing well, Velva. Don’t forget to feed it regularly with some organic tea. The garden loves it, especially when it’s hot. I’ll try to remind you when it’s potato planting time. Right now, it’s sweet potato planting time! Get some slips and slip them in!
I love the tips. We’re getting ready to move and will be able to plant a garden soon, but I’m totally inexperienced at gardening! I’m lucky enough to have a CSA near me, so my weekly farm box provides me with lots of fresh, organic vegetables to use in my recipes. While I’ll still be using a CSA when we move, I’m ready to try my hand at my own garden as well. I’ll be appreciating all the help I can get from other, more experienced gardeners!
oh yum-o. these are the things that make want to kill my brown thumb with kindness.
Thanks for sharing the recipe. We have been digging ours up and eating them for a few weeks now. Yesterday they were added to a roast and soaked up all that juice…FABULOUS!
I used to help out at my friend’s big veggie garden when I lived in England, my favorite was digging for potatoes! It’s like finding gold nuggets. You’re so right, no matter how you think you’ve got them all, there’s always more! This was a soup my friend used to make too. I hate cleaning out leeks, so sandy, do you have a trick?
Hello my Wokstar friend! I planted my leeks right along the front of my potato bed since I wanted to harvest them together. I mulched the leeks well, and they were not dirty at all. If you have sandy/gritty leeks, the best think to do is to trim them, slice them in half, and soak in a pot of cold water, then rinse and soak again. Repeat until you don’t see sand in the bottom of the pot. Then they’re ready to use! Fresh leeks have amazing flavor and texture, so they’re worth a few minutes of soaking and rinsing.
Wonderful harvest you have growing on, love the recipe you’ve shared. Most of all I am enjoying the comments from other gardeners when I posted your article to my fb pages. The information you have shared here is truly helping other growers in their gardens Thank you Annie
Thanks, Annie. Maybe I’m not linked to your FB page, because I don’t see the comments (which I really enjoy, too). I’ll go check and make sure we’re linked in on FB.
