How to grow sweet potato in the home garden

Sweet potatoes are grown from slips and not seeds, slips are shoots that are grown from mature sweet potatoes or to put it another way slips are small pieces of tuber which are removed or sliced from the sweet potato plant.

1. Sweet potato is a warm season plant that can be planted from spring through summer. Wait until after the last frost when the soil has warmed up.

2. Look for an area that gets 5-6 hours of sunlight.

3. The soil should be a loamy, sandy soil. Adding organic matter can improve the soil structure. The soil ph should be slightly acid anywhere from 5.0-6.5 some person prefer to use neutral soils.

4. 6-7 weeks before planting sweet potato slips, place the potato slips in a container or box of moist sawdust or sand. Place your sweet potato in a warm area that has temperatures of 75-85 degrees.

5. When transplanting into the ground or garden area don’t plant too deeply ensuring that the entire roots are totally covered with the soil. Plant slips in rows of 12-18 inches apart.

6. Keep the soil well watered but not soaked or waterlogged because this will encourage fungal disease.

7. Fertilize your sweet potato slips with 5-10-10.

Slice sweet potato

  • Mites
  • Aphids
  • Wireworms
  • Crickets
  • White Grubs
  • Flea beetles

Word of caution: When using chemicals follow the direction on the label because the label is the law.

1. Mites are tiny insects that are hard to spot, place a piece of white paper under your plants’ leaf and gently shake the leaves. If the pest issue is spidermites you will see tiny specks moving around on the white sheet of paper also spider web will be attached to plant leaves which is another indication that mites are present.

Other signs include weakening of plants, stunted growth with coloured specks on plant leaves. The use of neem oil, insecticidal soaps or purchasing predatory mites will help with this issue.

2. Aphids are soft-bodied insects that are pared shape which cause injury by sucking the plant’s juice. Leaves will yellow and then turn brown, a strong spray of water will knock them off killing them.

Another solution is the use of insecticidal soap, horticultural and neem oil or a homemade mixture of soapy water in a 32oz spray bottle will help.

3. Wireworm lives in the soil and feeds on the roots of the sweet potato, damage roots are unable to take up water and fertilizer causing the plant to stress. Yellowing and browning of leaves are also an indication that plants are being stressed.

To control wireworm drench soil with pyrethrin, applying beneficial nematodes, crop rotation or treating with sns 203 will give good results.

4. White Grubs are insect pest that lives in the soil, white grubs feed on the roots of plants making it impossible for plants to take up water and nutrients. These insect pests are active in the spring and early summer.

White Grubs are white to brownish in colour and can be found curl in a form that resembles the letter c. This insect can be controlled with the use of beneficial nematodes which is a safe and effective approach.

5. Flea beetles are responsible for blight and wilt. These beetles are black and have the ability to jump like fleas when bother. The flea beetles also have large rare legs and their bodies are small and shiny. This insect pest eats parts of plant leaves spreading bacterial diseases.

Control flea beetles by using white sticky traps, 70% neem oil or diatomaceous earth have proven to give good results.

Disease of sweet potatoes

  • Fungal leaf spot
  • Stem rot
  • Sweet potato scurf
  • White blister

Keep an eye out for these diseases and try these methods for control.

1. Stem rot causes the older leaves to wilt and then drop, the younger leaves, at the tip of the vines turn yellow. The inner stem at or below the soil line has brown streaks and are discoloured. Planting resistant varieties have proven to give good results.

2. Sweet potato scurf is brought on by damp, wet conditions along with poorly drained soil. This disease appears as blotches on the outside of the roots that are light brown with irregular patches.

To avoid sweet potato scurf cut potato slips just above the soil line and treat seed potatoes with a fungicide before planting.

3. White blister is a disease that appears as a white crusty growth along the leaf veins that looks like grains of salt. This disease is brought on by poor cultural practices which involve overwatering where poor air circulation is an issue also high humidity during cloudy, cool conditions.

Control measures include providing proper air circulation by thinning out plants, sweet potato slips should only be watered when the top 2-3 inches of soil is dry to the touch.

If growing in containers ensure that saucers are not holding water also move the container to an area that gets plenty of air circulation.

4. Fungal leaf spot appears as black or brown water-soaked spots on the leaves in some cases with a yellow halo. Under wet conditions, those spots will become larger.

As spots numbers increase entire leaves may wither and drop. To control this disease plant resistant varieties, applying copper base fungicides or sulfur sprays at early detection will benefit your plant in a great way.
