For anyone that has experience with ornamental sweet potato plants. 1) is this an ornamental sweet potato plant? 2)it’s growing rapidly/seems healthy but I’ve noticed that the bigger/oldest leaves now have tiny holes (pictured). I haven’t found any bugs - what could it be and is harmful? 3) it started out as a 6 inch plan, now it’s about 2 feet in a month. The roots are coming out of the bottom, is it time to repot and if so, what size pot should I use? I’ve already bought a trellis to kind of wrap it around. 4) will It actually produce sweet potatoes? 5) best way to propogate? Any other information that can be provided about the care of this plant would be greatly appreciated. It’s absolutely beautiful. I just want to know how to take care of it as I have no experience.

    Little holes on sweet potato leaves are likely caused by insect feeding, with possible culprits including flea beetles, tortoise beetles, or caterpillars. The holes can also be caused by snails or slugs. For sweet potato roots, wireworms and other soil insects can also create holes. Here's a more detailed breakdown: Leaf Damage: Flea beetles: These tiny, black or bronze beetles create small, shot-hole damage on leaves. Tortoise beetles: These beetles, sometimes with a tortoise-like appearance, also feed on leaves, causing holes or scraping. Caterpillars: Various caterpillars, like armyworms and hornworms, can defoliate sweet potato plants, leaving behind holes or consuming entire leaves. Snails and Slugs: These pests can also chew on leaves, leaving irregular holes. Root Damage: Wireworms: These larvae of click beetles bore holes into the potato roots, often with the hole lined with potato skin. Other Soil Insects: Rootworms, white grubs, and whitefringed beetles can also damage the surface of sweet potato roots. Remedies: Identify the Pest: Carefully inspect the leaves and roots for insects or signs of their presence. Look for droppings, larvae, or beetles. Control Methods: Insecticidal soap or horticultural oils: These can help control some insects, including aphids and flea beetles according to Melinda Myers. Neem oil: This natural insecticide can be used to control various pests. Spinosad: This insecticide can be effective against a range of chewing insects, including caterpillars, slugs, and snails. Sevin dust: This can be used to control caterpillars and other chewing insects. Handpicking: For small infestations, handpicking insects and dropping them into soapy water can be effective. Beer traps: These can attract and drown slugs and snails. Soil Treatment: For wireworms and other soil insects, consider soil treatments like pyrethrin-based insecticides or beneficial nematodes. Cultural Practices: Weed control: Keeping garden areas weeded can minimize pest habitats. Crop rotation: Rotating sweet potatoes with other crops can help disrupt pest cycles. Early planting: Planting early can help avoid peak pest populations.
