There was certainly no danger of me winning the 99 Pound Potato Challenge with this year’s ‘Rose Gold’ crop even though it is a new Personal Best for us here in the Dirt to Dinner garden. In 2010, we harvested 20 lbs of potatoes from a fifteen square foot raised bed and this year we managed the same weight of harvest in only nine square feet. That’s almost an extra pound of potatoes harvested per square foot in 2011. And this patch of potatoes also produced flowers and potato berries that were harvested so that we can experiment with growing from seed.
The ‘Rose Gold’ potatoes were planted March 29th and harvested July 19th, 112 days later. They were planted in new ground that started out as a compost pile and was covered in a layer of rice straw and top soil. Potatoes were hilled to just over 24″ with alternating layers of straw and potting mix. They could have been hilled much deeper. Vines were over four feet tall and some stolons grew at least two feet long. With their excellent taste and this respectable harvest, ‘Rose Gold’ potatoes will probably gain a spot in our deep hilling trials this fall or next spring.
Unfortunately, I was not the first one to harvest the ‘Rose Gold’ patch. Just the other day the dog was chasing something and digging along the edge of the patch. I shooed her away and went back to watering the tomatillos. But today in that corner, I found at least six potatoes that were very strangely shaped and clearly no longer at their full weight when it came time for the count. Do squirrels eat raw potatoes? Who eats raw potatoes, can climb the fence into the yard and is faster than a streaking Labradoodle? Those potatoes started fist-sized, if you have small hands like me, and a good chunk of them has definitely been chewed off!
The ‘Rose Gold’ potato vines were brown and fallen over and mostly dried up so I knew they were ready to harvest. I might have liked to allow the potatoes a few weeks undisturbed in the soil to harden their skins for storage but I pulled the patch before any more unauthorized feasting took place. I have two more patches and several potatoes in bags growing in that area. The patch shown here was planted April 6th and contains a broad mix of varieties for the Great Potato Grow Out Project. The bulk of the varieties still have lots of mostly upright, green vines. They wilt in hot weather but with water and evening cool they stand most of the way back up again. Except for the plant in the bottom right corner.
Potato varieties grow for a unique number of days before they finish setting tubers and the vines die back. Some early varieties are ready in as few as 75 days. The ‘Red Thumb’ potatoes have been the first in this trial to be ready for harvest at about 90 days. This vine is a ‘Caribe’ potato that is done growing and I plan to pull these potatoes very soon before anyone else starts to harvest them for me!
