These are problems people actually ran into growing sweet potato greens at home, in their own words. Each answer starts with the answer. Everything here is organic — compost and homemade feeds instead of chemical fertiliser, and no synthetic pesticide — and assumes a pot on a balcony, patio or windowsill rather than a field.
Yes, spotted sweet potatoes can be safely cured as long as the spots are dry and the tuber feels firm — but cut away any soft, oozy or mouldy patches first. Spots often come from scuffing, insect nibbles or a surface fungus called scurf; curing helps the skin toughen and seals minor wounds. A rotting spot, though, will spread during curing and ruin the whole batch.
To cure safely, sort through your harvest and keep only the firm, dry ones. Trim off any damaged area with a clean knife, then wipe the cut surface dry. Place them in a warm, shady, humid spot with good airflow — a balcony corner out of direct sun works. Leave them spaced apart so air moves around each tuber. Check every few days: any that turn soft, weep or smell sour should be removed immediately.
Once the skins feel set and any cuts have dried into a firm scab, they’re cured. Store them somewhere cool, dry and dark, and keep checking for soft spots during storage. Spotted but sound potatoes are worth keeping — just watch them closely.
To grow sweet potato greens as a beginner, plant a slip or a rooted tuber in a pot with at least 3 litres of soil, keep it somewhere warm between 15 and 35°C, and give it 6 hours of sun each day. That combination is the whole secret — sweet potato is a warm-season leafy crop that simply refuses to grow in cold shade.
Start by placing a sweet potato in a jar of water with the bottom half submerged, or just bury it halfway in moist potting mix. Keep it warm, and roots and shoots should appear within about 10 days. Once the shoots are a few centimetres long, snap them off and plant those slips in your container. Use a quality organic potting mix mixed with a little compost. Water whenever the top inch of soil feels dry — not before, not after. The leaves will be ready to harvest in around 30 days. Cut the larger leaves and leave the smaller ones, and the plant will keep producing. Feed every couple of weeks with diluted compost tea or a liquid seaweed feed. No chemicals needed.
Night-feeders — caterpillars or slugs — are eating your sweet potato leaves, so go out after dark with a flashlight and check the plants. These pests hide under the pot rim, in the soil, or on leaf undersides during the day, which is why your traps and daytime sprays missed them. Pick off every caterpillar, worm, or slug you find and drop them into soapy water. Wipe away any clusters of eggs you spot on the backs of leaves.
For slugs and snails, lay a damp old board or folded leaf on the soil surface near the plant — they’ll shelter under it by morning, and you can collect and dispose of them. Scatter crushed eggshells around the stem as a scratchy barrier they won’t cross. For caterpillars, inspect every few days and remove them by hand. If damage continues, make a garlic spray: soak crushed garlic cloves in water overnight, strain, and spray the leaves in the early evening.
Keep the pot in a warm, sunny spot — sweet potato greens need at least 6 hours of direct sun — and water when the top inch of soil feels dry. Unstressed plants resist pests better. Remove badly torn leaves and keep the soil surface clear of fallen debris where pests hide.
Put a physical barrier around your sweet potato—a wire cage or mesh cover—because squirrels are best stopped by blocking access, and that also lets you give it the 6 hours of sun it needs without them digging. Squirrels dig up tubers for food and burying, so wrap the pot in chicken wire or hardware cloth, or lay a wire grid flat over the soil with holes big enough for the vine but too small for paws. You can also scatter dried chilli flakes or crushed garlic on the soil surface; reapply after rain. Keep the pot in a sunny spot, since sweet potato greens need full sun (at least 6 hours) to grow well, and they thrive in warm conditions between 15 and 35°C. Water when the top inch of soil feels dry, using about 3 liters for a typical container. Harvest young leaves after about 30 days, or cut vines sooner to encourage regrowth. If a squirrel has already eaten part of the tuber, leave the rest in place—it can resprout from the remaining piece.
