It’s time to
plant sweet potatoes!
a sweet potato with slips still growing on it |
Last week we
got sweet potato slips from Crystal, a Grow Appalachia participant at St.
Vincent Mission. Crystal was growing a bunch of starts for other gardeners this
spring and gave us a great price on them. We were really happy to be able to
support a Grow Appalachia participant by purchasing plants from Crystal, and
the plants we received were beautiful. We were even happier after hearing
multiple reports that the sweet potato slips in many local stores looked sad
and sickly, a great juxtaposition to ours!

A sweet
potato is a warm season, vining, perennial plant, that is usually grown as a
food producing annual. Sweet Potatoes are grown from starts that are taken off
mature tubers and are usually referred to as “slips”. Sweet Potato slips should
be planted several weeks after the last frost date once the ground has had a
little time to warm up. Slips should be planted 12-18 inches apart in a hill
about 8-10 inches tall, because sweet potatoes are a vining plant you will not
be able to hill them up after planting, so it is important to give them enough
room to grow underground when you plant them. You should also plant sweet
potato slips in a dry area of the garden with plenty of room (3-4 feet between
rows) so that the vines will have some room to grow. There are many different
sweet potato varieties available that have red, orange, or even purple skin, different
colors of flesh, and a range of flavor from very mild to super sweet. The 2
types that we received are Beauregard and an old fashioned red variety.
Some common Sweet Potato Varieties
Beauregard:
100 days to harvest, light purple skin, dark orange flesh, extremely high yield
Bush Porto
Rico: 110 days to harvest, copper skin, orange flesh, compact vines and heavy
yield

On the
subject of planting sweet potato slips, does anyone know anything about trellising
sweet potato vines? We have, against our better judgment, planted our slips in
a narrow bed where the vines will most likely grow out over the grass. I have
read very differing advice concerning trellising or staking sweet potato vines
and we are not quite sure whether we should try it and risk losing what could
be a beautiful, delicious crop. One side of the argument is in agreement that
you should not trellis sweet potato vines because as the vines spread they will
root into the ground at many different points and each of these roots will then
produce tubers. So, if you trellis your vines and do not allow them to root, you
will end up without any potatoes. The other side of the argument reasons that
allowing your vines to root will rob the main crop of potatoes of nutrients and
you will therefore have many small potatoes rather than fewer large potatoes,
so following this advice trellising is a fine way to save space and still
produce large potatoes. Have any readers experimented with trellising sweet
potatoes or have any advice to offer? Any suggestions would be greatly
appreciated!
And an added bonus to planting sweet
potatoes: They are really healthy!

Sweet
potatoes are high in Vitamin C, calcium, folate, potassium, and beta-carotene.
They also have a low glycemic index, which means that they will not cause great
spikes in blood sugar levels. Sweet potatoes have a glycemic load of 17
compared to a white potato which has a glycemic load of 29. And, sweet potatoes
are really delicious!
Thank you Crystal and St. Vincent Mission for the Beautiful slips!!
you're welcome. Thanks for buying local!!
