Ash Wed is Feb 14th, so Easter is March 31st. I really don't think we will be planting potatoes on Good Friday. Here is the reason why. Garden will not be ready.

      It sounds like another awesome day for us.  The temperature at 7:45AM is 27 degrees with a high today in the 50’s.  We have blue, clear skies so almost perfect, and it is Feb. in Iowa. We are having highs to take care of that cold we had in January to get the averages to come out.  Lows tonight of 33 while the average temperature is 17.  I worked in the greenhouse yesterday and I had the doors open.  It was pleasant to be in there just as I was cleaning not planting yet. I will do more cleaning and see what happens later this week.  All of you enjoy this weather and stay safe. 
Ash Wed is Feb 14 so Easter will be March 31st.  I hate to say, but don’t think we will be planting potatoes on Good Friday.  Here is what the soil, and the temperature needs to be to plant those potatoes. 
​
Potatoes aren’t fussy vegetables, which makes them a fabulous choice for first-time growers. They do well in most soils and almost always produce plenty to hunt for at harvest time. That said, you can do a few things to elevate your crop.
You’ll need a location with at least 6 hours of direct sunlight and fertile, loose, well-drained soil; hard or compacted soil leads to misshapen tubers. Ideally, the soil is slightly acidic (pH 5.8 to 6.5), and the soil temperature is at least 45º to 55ºF (7° to 13°C). In the fall, mix compost or organic matter into the soil. Learn more about compost, soil amendments, and preparing the soil for planting.)
When to Plant Potatoes
Garden potatoes can be planted 2 to 4 weeks before the average last frost date. The soil temperature should be at least 55°F during the day and 45°F at night. But pay more attention to the soil than the calendar to determine planting time. The soil should not be so wet that it sticks together and is hard to work. Let it dry out a bit first. If you have a late and wet spring, you can plant later—through April (depending on location) or even June, especially in containers.
In cooler regions, the early-maturing potatoes are usually planted early to mid-April. In warmer regions, planting times range from September to February; in central Florida, gardeners plant potatoes in January; in Georgia, they plant in February.
4 Methods of Plant Potatoes
There are different approaches to planting potatoes.
Dig Holes: For each seed potato, dig a hole about 6 inches deep (or 16 cm). Add in a little slow-release organic fertilizer (e.g., chicken manure pellets) and then pop in the potato with sprouts pointing up and cover with soil. Space potatoes about 16 inches (or 40 cm) apart in both directions for early types. Maincrop potatoes need a bit more space to stretch their legs, so space them at 18 inches (or 45 cm) apart.
Dig V-Shaped Trenches: Dig 2- to 2.5-foot trenches (60 to 75 inches). Lay a nourishing cushion of garden compost along the bottom and a few of those chicken manure pellets, then set your tubers into position about one foot or 30 cm apart. Then just fill back in. I don’t think it makes a huge difference which way you plant, so do whatever’s easiest in the space you have.
Plant in Straw: Nestle seed potatoes down into the soil surface, then cover them with straw. See our article on planting potatoes in straw.
Plant Potatoes in Pots: If you don’t have the garden space, plant in large containers, old compost sacks, or purpose-sold potato sacks. Fill the bottom of your pot or sack with about 4 inches (10 cm) of potting mix, then lay one or two potatoes on top and cover. Once the foliage is growing, add in more potting mix, a bit at a time, to hill or earth them up until the soil level reaches the top at which point the foliage almost seems to explode in size.
GROWING
Watering Potatoes: Firstly, water! This is really important because potatoes are lush and leafy plants, and those tubers take a lot of effort to swell. So if it’s dry, water thoroughly. Maintain even moisture, especially from the time after the flowers bloom. Potatoes need 1 to 2 inches of water a week. Too much water right after planting and not enough as the potatoes begin to form can cause them to become misshapen. Stop watering when the foliage begins to turn yellow and die off.
If you’re growing in containers, take extra care to keep your plants really well watered, especially in warmer weather, as this really will make all the difference in achieving a good crop.
 Hilling Potatoes: The potato flavor is improved by depth and darkness.   As the potato plants grow above the soil surface, you’ll need to periodically “hill up” or mound up soil and compost around the plant so that only the top leaves stick out of the ground.   Becky’s note ( a way to think of this, is the potatoes all form on top of that seed potato you put in the ground.) 
It’s vital not to allow potato spuds to be exposed to sunlight, as this also causes them to turn green and produce a chemical called solanine, which gives off a bitter taste and is toxic. Do the hilling in the morning, when plants are at their tallest. (During the heat of the day, plants start drooping.) Just draw up the soil with a hoe every time the stems get to around 6 to 8 inches (15 to 20 cm) tall so that just the very tops are left poking out. Continue doing this in stages until you can no longer draw up any more soil, or the foliage closes over in between the rows.
If you’re growing your potatoes in a smaller raised bed, it may be easier to simply top up with organic matter around the whole area.
Hilling keeps potatoes from getting sunburned, which can cause them to turn green and produce a bitter, toxic chemical.
Protect From Frost: Late frosts can damage the young foliage – something to watch out for with early starts. Frost-bitten plants usually have enough energy to shake off any damage, but it can set plants back nonetheless. So if a frost is forecast and potatoes stand to get clobbered, do whatever you can to protect them. Cover the area in a few layers of warming fleece or row cover fabric, cover clusters of shoots with pots, or draw up the soil to bury the young shoots.
