Random question regarding potatoes? Is it better to leave in the ground for as long as possible? as in In I could pull an i
entire bed this week but would it be better to pull half this week and then the rest in a few week?
I agree with Durgan...but it does depend on your climate. Here in East Texas we often have wet and humid conditions about the time the potatoes are maturing and hot weather is pending. In that circumstance, getting them out of the ground before rotting is paramount.
I usually begin robbing the new potatoes after the blooms fade. This allows utilization over a longer period of time and utilization at the peak of flavor. For example, we can add about 3 to 4 weeks to our potato utilization this way. It also has the side benefit of spreading out the harvesting work.
I always immediately follow the last of the potato harvest with a nitrogen fixing cover crop planted in that space. That cover crop will be replanted in the fall if necessary and allowed to soil build all the way through to next spring. Then, in spring, after turning it under and prepping the seed bed I like to follow up with a legume like beans or peas or whatever. Potatoes will not be grown in that space for another two years at least.
For example, next years potato crop will come from this space which currently has soybeans growing and fixing nitrogen. This fall, I will turn the soybeans under and plant in a mixture of Elbon rye and legumes there to carry through to next Feb. when that next years potato crop will be started.
As for this years potato ground, it is currently planted in alfalfa and will remain so through next spring when I will probably turn it under and plant corn in that location. Corn loves nitrogen and the alfalfa adds the most N2 I have found in the legumes.
With this approach, we consistently average at or well above 10 pounds of harvested new potatoes for every pound of seed potato. The potatoes will be disease free and mostly insect free following this regimen.
What you do to prepare for the next crop is often much more significant than what you do to actually grow it. At or above 10 to 1 ratios do not happen by accident.
