Step 2: Choose the Right Potato Variety for Container Cultivation
Selecting the suitable potato variety is crucial for successful container cultivation. In regions with shorter growing seasons, such as the low desert of Arizona, opt for “early” and “mid-season” determinate potato varieties. Determinate varieties grow rapidly and provide a smaller harvest in a shorter time frame (around 60-90 days). Some recommended determinate varieties include Yukon Gold, Purple Viking, and All Red.
For areas with longer cultivation seasons, go for indeterminate or “late season” potato varieties. These potatoes yield a larger harvest over a longer period, usually between 110 and 135 days to fully mature. Indeterminate varieties continue to produce new potatoes along the stem until they are harvested or stopped by frost. Consider trying varieties like Russian Blue, Canela Russet, and Ramona.
For the best results, always purchase certified disease-free seed potatoes from reputable online vendors or gardening centers.
Step 3: Prepare the Potatoes for Planting
To prepare the potatoes for planting, place them in an area with temperatures ranging from 60-70℉ and expose them to light. This process, known as ‘chitting,’ promotes potato sprouting. Once the potatoes have sprouted, if they are larger than an egg, slice them into pieces, making sure each piece has 2-3 eyes.
Step 4: Timing the Potato Planting
In cooler regions, plant your potatoes just after the final frost date. However, if you are in the low desert of Arizona, the ideal planting time is anytime from September through January.
Be cautious of frost, as potatoes are sensitive to it. If a hard frost kills your plants, harvest the potatoes, regardless of their size, within a week or two to prevent decay.
