Also, you have to consider your species — ornamental sweet potato vines will take these symptoms far better than fruit-producing vines.

– Leaves Turning Brown and Yellow

Leaves going brown or even yellow are one of the most obvious signs that you’ve overwatered your vines. If the soil is moist and spongy you should stave off your watering for a few days and check how the plant behaves.

Brown leaves may point to issues with fungi like fusarium wilt or root rot, so if the problems persist you may want to separate your plants to prevent the disease from spreading. Also, you’d probably need to resort to pulling out that fungicide sprinkler!

Leaves turning yellow, on the other hand, may indicate a nutrient deficiency — specifically, a lack of nitrogen! If yellow leaves persist after you’ve fixed your watering regime, you may want to add some nitrogen and magnesium-rich fertilizer to the soil!

– Leaf Wilt

Leaf wilt will most likely be directly connected to sweet potatoes’ water problems! Sweet potato vines can do well without water for more than a week and longer! So, if you’ve been overwatering them, they’ll first show it by wilting leaves.

Be mindful, however, as leaf wilt may point out fungi issues such as fusarium or verticillium wilt too! Wilts also cause your plants to droop to the ground and shed leaves, just like overwatering. So, if your wilting problems persist even after you’ve cut back on the water, you may want to cut off those wilting leaves and burn them to prevent the fungi from spreading!

These diseases will more readily attack your fruit-producing plants than ornamental sweet potato vines. In short, don’t worry about giving your vines a few days of breathing time, as cutting back on watering will lower the chances of disease spread.

– Leaf Curl

This symptom is another common overwatering result but may point to a more serious issue. Leaf curl is sometimes caused by a virus disease from the begomovirus group infecting the sweet potato family!

Also known as the sweeping virus this one is a relatively new and hybrid type of viral sweet potato disease that emerged as a result of progressive and aggressive vegetable and root crop production!

Plants often do not show any signs of disease or symptoms, but will at times begin to curl up and show stunted growth — most often in the summer, exactly when your overwatering issues may appear!

If you notice that your leaves began to curl for no reason, stop giving your sweet potato vine plant water for a few days. If the problem persists even after the first few inches of soil went dry, then you know you probably have a viral disease on your hands.

Seasonality in weather will have a major influence on how often you’ll need to water your vines. For example, summer is a season when you can expect extended drought periods, so you should watch out for these and be ready to step in.

Conversely, if it’s springtime, there’s a high probability of the rainy season where you should cut back on watering sweet tater plants. Nevertheless, both droughts and rainy seasons can interchange in both seasons.

These plants have strict light requirements — enjoying the full sun and plenty of it. But they won’t cope so well with extreme heat — not without the water, that is. That’s why you should consider a good sunlight position but also be responsible about your watering in such conditions. Don’t allow your vines to burn up by giving them plenty of water, and they will reward you.

– Schedule Watering

The growing season in general will determine the frequency of your watering too! Much like the weather, the spring season will require at least two to three waterings a week, summer almost on the daily, while you’d want to cut back on this frequency when fall begins and your plants are well established in the garden!
