Plant sweet potatoes regarding 12 to 18 inches apart, and also enable 3 feet between rows so the vines will certainly have a lot of areas to expand.

When setting out sweet potatoes in really warm, sunny weather, cover the plants with upturned blossom pots for 3 days after growing to secure them from baking sunlight.

Sweet potato seedlings in containers tend to become root-bound. When the roots– which become the actual sweet potatoes– start to grow in the pot, they will frequently circle the inside of the pot. As soon as that takes place, there’s a possibility they will not complete correctly.

For functions of this short article, sweet potatoes and yams can be utilized interchangeably. Sweet potatoes are in the very same household as early morning glory flowers.

WHEN TO PLANT-Do Sweet Potatoes Grow Underground

Sweet potatoes/yams mature in 60 to 270 days, depending on the variety. They are incredibly frost sensitive and can not be exposed to any frost whatsoever. Northern ranges are normally grown in raised beds with black plastic “mulch” to keep the soil warm and promote more powerful growth. In the North, cover the raised rows with black plastic to keep the soil warm and promote strong growth. In warmer Southern environments, planting typically happens between mid-March to mid-May, once again, depending on the range chosen. It is suggested that you wait to plant sweet potatoes/yams a couple of weeks after the last frost.


More than anything, sweet potatoes and yams like warmth, and absolutely nothing offer that along with complete sunshine for as numerous hours in the day as they can get it, but a bare minimum of 6 hours daily. They can do well in warmer Southern climates in partial shade, however again, make certain they get their 6-hour day-to-day minimum. It is very important to note that sweet potatoes can be harmed by temperatures lower than 50F.

Yams do best in fertile, light, and deep sandy loam. Your soil requires to be well-drained but wet, and nutrient-laden. There are a couple of ranges such as Centennial that have been reproduced to be tolerant of heavy, clayish soils. Sweet Potatoes can be grown in all sorts of soil, but they do best in the soil explained 2 paragraphs previous. They don’t do well in rocky soil as the rocks misshape the roots.


Sweet Potatoes and Yams prefer a little acidic soil in the series of 5.0 to 6.0, however, will endure varieties as much as 6.5. The Sweet Potato/Yam doesn’t do too well in soil that’s too nitrogen-heavy as it will put out long vines and relatively couple of potatoes. Usually, an excellent compost will offer the majority of the Nitrogen, Phosphorus, and Potassium your yams will require. Sweet potatoes require a great supply of Zinc. Build raised ridges – ready to 12 to 18 inches – spaced 3 and a half feet apart. Mix in lots of garden compost to your soil, about 12 to 18 inches deep. Lots of compost equals about 4 to 6 inches deep down your rows. You must be able to anticipate about 1 lb. per foot of row planted.


As a member of the early morning magnificence household, it’s not a surprise that sweet potato vines can get up to 20 feet in length or more. As the vines touch down to the soil, they’ll root and produce more bulbs. If you have actually utilized a black plastic mulch or perhaps straw mulch, you can carefully keep the vines from rooting so that they put their energy into the yams under the primary plant which will be the bigger fruit.

If you’re growing simply a little spot of sweet potatoes, you can trellis the vines to keep them from re-rooting.

As the season nears harvest, ease up on watering and stop completely 2 or 3 weeks prior to you plan to collect your sweet potatoes. Over-watering late in the season might trigger the roots (potatoes) to break, grow, or rot.


Summer season Savory makes a good buddy to sweet potatoes as it reputedly puzzles and in some cases fends off the sweet potato weevil and is stated to include minerals to the soil.

The majority of crops succeed following vegetables such as peas and beans since these crops “repair” the nitrogen in the air into the soil, benefiting any crop that follows. Some garden enthusiasts radishesgrow these crops alongside beans, but you have to safeguard the beans as the sweet potato vines might choke them out.

Dill attracts hoverflies and predatory wasps and wards off aphids and spider mites to some degree.

Oregano drives away the cabbage butterfly as well as the cucumber beetle. Squash and Sugary food Potatoes complete because of their vine sprawls. You need to give both crops great deals of space.

Be very mindful not to nick or bruise the roots as it will impact their storage longevity. You can selectively harvest in mid-summer by getting rid of “outlier” potatoes but not harvesting too near to the primary plant stem.


The factor’s finest to harvest sweet potatoes or yams on a warm, dry day is that it’s a best practice to allow them to cure in the sun for a couple of hours. Even after that, they save best if they can begin in a warm, dry, and well-ventilated area for 10 to 15 days at 85 to 90F. After this preliminary drying duration, the yams and sweet potatoes keep best at around 55F at about 75% humidity.

If you rototill your garden in the fall, it helps to expose or eliminate larvae and pupae.

If you have just a couple of plants, you can make a cardboard or aluminum foil collar to dig in a few inches around the base of your sweet potatoes/yams; this makes a physical barrier to keep cutworms from feasting on the base of your plants.

Diatomaceous Earth is really effective versus cutworms, however, remember that it just works if it’s powdery and requires re-applied if your plants and soil end up being wet.

Root-knot nematodes burrow into roots and cause pimple-type growths on the roots.

Black rot is a fungal disease that causes dark circle-shaped depressions on your yams or sweet potatoes.

While black rot looks rather like “scurf” – small, black areas on sweet potatoes that don’t impact the consuming or storage quality – however, triggers yams and sweet potatoes to rot, unlike scurf. Black rot can be avoided by planting rot-resistant ranges, rotating your crops on the basic 4-year rotation, and not over-watering.

Dispose of contaminated bulbs upon discovery.

Stem rot or stem wilt get in plants that have actually been damaged by wind, careless handling, or bugs.

Stem rot will impact the quality and production of your garden’s sweet potato crop.
