After Potato harvest, then what?

cbgardenJune 10, 2012

I live in LA, and just harvested (June 10, 2012) some fist size potatoes (my first - yea!). I also found some little seed potatoes which i left in the ground. The plant tops have completely died back. Do I continue to water the tiny seed potatoes and will they grow now ?

Potatoes are a cool weather crop. Warm soil temps will often just rot any small ones left in the ground before they can sprout. Most gardeners save them for planting in the cool fall or spring next year.

You can try of course and see what happens but I'm assuming that S. California weather wouldn't be at all potato planting friendly right now. :)

In your climate saving them may be a problem. In the mid-west folks use root cellars and cold basements - they need darkness and max air temps of 45-50 degrees to keep. If you have room in the veggie bin drawer of the fridge they will keep there. In the old days folks used to bury them in a covered bucket in the back yard if they didn't have a root cellar.

In warmer climates most start with fresh seed potatoes each spring because stored ones just don't last long enough.

If you monitor your soil temps as needed then you may be able to plant them this fall if your soil temps get down to 45-50 degrees and get a crop then.

Potatoes missed or left in the ground at harvest generally do not sprout for a couple months...built in sprouting resistance.

In old times in Virginia, we would dig the spring potatoes in late June early July. The little potatoes would be left in the sun for a week or so until they began to green up and then planted for a fall crop to be dug in late September - early October. We grew Irish Cobblers in those day which are a relatively quick maturing potato. The bottom line is that they will sprout readily if exposed to sun for a week or so.

farmerdill, thanks for the tip about getting little potatoes from early summer harvesting to sprout for replanting and harvest in fall.

I did a search to find the post again since I remembered reading it, but didn't recall details. Just the answer my daughter needed today.

Garden web is great for the practical tips shared from experienced gardeners!

Just harvested my spring crop of potatoes. Several good eaters, lots of good seed, and one classic "can't show this one polite company" potato.

When is the best time to start the fall crop? We're still hovering around/above 100 degrees here, so I'm assuming the answer is not "now".
