When we were at the mouth of the valley, we were too far away to see clearly. But as we got closer, we discovered that the area around the foot of the mountain to the east was covered with sweet potato vines. Roughly speaking, it should be about an acre in size. I wonder when these wild buffaloes discovered this sweet potato field. Now, only about half an acre of the land remains intact.

The bison seemed to prefer eating sweet potato vines rather than the sweet potatoes underground. In the half-acre sweet potato field they ate, many sweet potatoes remained shallowly buried in the soil and were not dug out.

She casually dug out four or five sweet potatoes, each one round and plump, similar in appearance to the one the bison had held in its mouth yesterday. They were all round sweet potatoes, about half the size of a child's fist, and weighed only one or two ounces in her hand.

Su Hua frowned. She studied traditional Chinese medicine and wasn't very familiar with the habits of non-medicinal plants. Based on the sweet potatoes she had seen in China before, each one weighed anywhere from seven or eight ounces to several kilograms, and there were even giant sweet potatoes weighing dozens of kilograms.

These sweet potatoes are so small now, I don't know if it's because of insufficient nutrition or because it's only early April. April and May are the season for planting sweet potatoes, and these small sweet potatoes in the field look like they were left over from last year.

Da Niu and Da Bai, standing to the side, paid no attention to any of this. Seeing that Su Hua had dug out four or five sweet potatoes, they began to dig the pit with their tiger claws. The shallow sweet potatoes were dug out with a single claw, while the sweet potatoes in the deeper soil could not be dug out by their claws, so they began to open their tiger mouths to bite them.

In just a few breaths, the two of them had already dug out a plot of land, with seventy or eighty round sweet potatoes scattered on the ground. Their once snow-white fur was now covered in a mixture of black and yellow mud and ash, just like glutinous rice balls that had burst open in the pot and were covered in sesame filling.

Su Hua burst out laughing, no longer worrying about whether it was due to insufficient nutrition or the season, and clapped her hands as she walked towards the sweet potato vines in front of her.

Sweet potato cultivation is divided into tuber cultivation and stem and vine cultivation. Tube cultivation involves burying the entire sweet potato in the soil and then transplanting the sprouts after they have taken root and sprouted. Stem and vine cultivation involves directly inserting sections of sweet potato stems and vines into the soil, which is essentially a type of cutting propagation. Compared to tuber cultivation, stem and vine cultivation is faster and has a higher survival rate.

Moreover, there are less than an acre of sweet potatoes left here, and she feels bad if even one is missing.

In April, the sweet potato vines were extremely tender and could be broken with a gentle pinch. She would put each handful she pinched directly into her spatial storage until she had pinched half of the remaining half-acre of sweet potato vines before she stopped.

She had enough cuttings, enough to even stir-fry a dish or two of sweet potato leaves. As for the rest, she would leave them to the bison herd. As long as they didn't uproot and overeat them, more sweet potatoes should grow in the valley after this summer.

Su Hua stopped what she was doing and quickly told Da Niu and Da Bai, who were panting heavily behind her, to stop too. She then brought out a large basin of spatial water droplets and about ten crabapple fruits and placed them in front of them.

Aside from being a bit greedy, these two are usually very well-behaved, and she's happy to spoil them.

Almost as soon as the spatial water droplet and the apple landed, the two panting figures stopped abruptly. Immediately, their clear yellow and azure eyes were filled with starlight, and their two long tails wagged rapidly behind them.

The big girl even stood on tiptoe with her chubby tiger paws, stretched out her tiger body, and brought her tiger mouth close to the girl's pink cheek, giving her a big kiss.
