Chitting is simply allowing and encouraging your seed potato to sprout before you plant it in the soil. It isn’t necessary, but it does give your crop a quicker start since you can chit the potato 4 to 6 weeks before it is time to plant them outside. Potatoes like cool weather but do best when planted either two weeks before or after the last frost of spring. They prefer full sun but will fall over in die if they get to hot.
It is important to buy seed potatoes and not use those from the grocery store. The potatoes you buy to eat have been sprayed with chemicals (another good reason to grow your own) that reduces/eliminates sprouting and they can harbor viruses that you do not want to introduce into your garden.
Chose the type of potato you wish to grow by harvest date and your taste preference. Yukon gold potatoes are ready to harvest by mid-season. Superior potatoes are ready to harvest by mid-season.Red Pontiac potatoes are ready to harvest later in the season. Kennebec potatoes are ready to harvest mid- season. Canela Russet are ready to harvest later in the season.

My Canela Russet before being placed upright in a tray.
Once you have chosen your variety you need to prepare them for planting.At the least a week before planting them into the soil set them out in a warm sunny place inside your home to encourage them to sprout (chit). Check the potato and place the part with the eyes upright and the stem area down in a tray or egg carton.
After about a week you will see growth from the potato eyes.

Two days before planting take any potato that is bigger then 3 inches and slice it into 1 1/2 inch pieces with each piece containing at least two eyes or chits. Be careful not to break the sprouts off when cutting. Potatoes less than 3 inches should be planted whole. Allow the cut potatoes to air dry on newspaper for two to four days so that a thick callous can form over the cuts to protect them once they have been planted.

Prepare your potato bags and plant the potatoes cut side down using one of the two methods described in the potato bags entry. I used the “hill – up” method. I filled the bottom of each tub until it was approximately 1/4 of the way filled. Than I added 4 to 10 seedling potatoes spread equally across the surface.

Cover the potatoes with more soil until the tub is half full.
When the potato plants are 8 to 10 ” tall I will fill the tub with more soil until it is 3/4 full. I will
finish filling the tub when the plants have grown another 6 to 8 “.

The potato bags are on the corners. They are covered with a piece of screen to prevent the cats from digging into them. Once the potatoes start to grow I will remove the screens and add more soil. The area is still a bit of a mess since it is a work in process.
Keep the potatoes well watered especially when they are flowering but do not soak them. It is best to water early in the morning so that the leaves can dry before nightfall.
Depending on which method you choice you may need to add more soil to “hill-up” the plant. After five weeks this needs to be done about every 2 to 3 weeks.
You can begin to harvest “new” potatoes which are very small about 2 to 3 weeks after the plant has started to flower. To harvest these potatoes carefully reach in and remove the largest potatoes leaving the very small ones along. Replace any soil that you displaced. You can do this all season long just remember that the mature harvest will not be as big.
The mature plant leaves will start to turn yellow or brown when the plant is ready to be harvested. Stop watering and allow the area to dry for about a week before dumping the bag ans collecting the potatoes.
Do not store the new potatoes immediately but allow them to dry onto top of the soil or on an airy porch if it is raining so that the skin can toughen up.Do not wash the potatoes before allowing them to dry.
Store in a cool dry place until you eat them!
