My mother-in-law spent 8 years growing a moss rose into an old stump, and she wouldn't sell it even when a neighbor offered 20,000 yuan!
Nowadays more and more people like growing flowers, but after growing them for a long time, quite a few people end up killing their plants; some flower enthusiasts are smarter and specifically grow flowers that need little care, which stay perfectly alive even without watering for a month. The editor has a pot of moss rose at home that my mother-in-law has grown for 8 years, and it usually gets hardly any care, yet unexpectedly she managed to grow it into an old stump. Our neighbor Aunt Wang is a bonsai enthusiast and wanted to pay 20,000 yuan to buy this pot of moss rose for a bonsai, but my mother-in-law refused. Let's take a look at how my mother-in-law did it!
Many flower enthusiasts will surely find this two-tiered moss rose incredible when they see it, because we all know that moss rose is sown in spring, blooms in summer, and dies in winter. It was only after seeing this pot of moss rose that I felt I had learned quite a lot, and realized that moss rose can actually be grown this way too!
My mother-in-law says moss rose likes plenty of light, and our balcony happens to meet this condition, with sunlight visible from morning to night. Normally there is no need to water it often; when the soil in the moss rose's pot looks dry, just give it a thorough watering until water flows out from the bottom of the pot.
Moss rose is famously easy to grow, and its other name is "the unkillable one"; it grows well even without care. My mother-in-law says that if you want your moss rose to grow vigorously and bloom abundantly, you should normally dig a small hole at the edge of the pot, bury 3-5 granules of compound fertilizer, and cover it with soil. It doesn't need much fertilizing during the growing period; fertilizing once every two weeks is enough.
If you want to grow a moss rose into an old stump, you must choose those perennial moss roses. Cut a few moss rose branches to serve as rootstock, and after trimming and drying them, graft them onto the mother plant. Use string to tie the moss rose scion and the rootstock together, then place the grafted moss rose directly in the sun for care. It takes only about 1 week for it to take, and afterwards, as long as it is cared for well, it can grow into an old stump!
