Evergreen succulents overwintering experience
Let me tell you about the introduction of succulents, the overwintering experience of evergreen succulents, keep reading!
Evergreen plants generally have no problems overwintering, just avoid long-term low temperatures and high humidity. Basically, no one would let them endure sub-zero temperatures. If the climate is humid and warm, it's advisable to control water, provide shade, or even stop watering to force them into dormancy. Most varieties do better outdoors in summer than indoors, but be careful of sunburn. In summer, the sun is really scorching.
Stonecrop genus, relatively easy to survive summer, quite heat-resistant, mostly native to Mexico, so you can give them some water. Some friends say it's hard to determine the right amount of water, too mysterious to figure out. Actually, just follow your own feeling. When it feels cool, there's a breeze, and it's comfortable, give them some water at night, and make sure there's ventilation. By the time the sun comes out the next day, the soil is relatively dry, and it won't be too steamy even with the sun high in the sky. Also, you're still providing shade, right? In fact, there's not much sunlight in the balcony during summer.
Crassula genus, relatively easy, refer to the stonecrop genus.
Sedum genus, this is a bit troublesome, many die in summer. Mr. Yang's place loses a lot every year. For example, the most common variety, Sempervivum, loses old leaves after summer, and if it retains 10 cm of crown diameter out of 15 cm after summer, that's considered quite good. They also die in patches, but this stuff繁殖 quickly. It's said that once they reach 15 cm, they can繁殖 200 seedlings a year. You need to strictly control water in summer; they won't die from drought, but from suffocation, smothering, or flooding. Just stop watering in July.
Haworthia genus, strong varieties don't matter, like Sempervivum. They can survive outdoors in Jinan in summer. However, make sure there are no water droplets on the leaf surface before the sun comes out, as this can cause burns and infections, leading to black spots, leaf drop, or even death. Small ones need special attention, especially those with tightly packed leaves, like Haworthia limifolia. Control water strictly at 30 degrees and stop watering completely at 35 degrees. Don't worry about them dying from drought; I learned this the hard way last year.
Echeveria genus, this genus is interesting. During summer dormancy, the leaves become shorter and wider, and all old leaves fall off, leaving only bare stems. This genus has a deep dormancy, and it's best to stop watering in July.
Graptopetalum genus, refer to the stonecrop genus, pretty much the same.
Sedum genus, in Jinan, varieties like Sedum spectabile and Sedum nussbaumerianum all survive summer outdoors. During midsummer, use shade nets to prevent leaf tip burns.
Echeveria genus, like Echeveria '紫武藏', Echeveria '江户紫', and Echeveria '不死鸟', all survive summer outdoors, and they are quite robust.
Roofwort genus, specifically the variety Sedum '子持年华' needs mention. It has two growing seasons in Jinan, flowering twice a year. Of course, I can't say every plant does this. After flowering in April, it basically doesn't go into dormancy, then flowers again in September. The flowering period is quite long, and after flowering, it goes into dormancy, the old leaves dry up, and the new leaves clump together. This stuff also survives outdoors in Jinan in summer. Other well-known varieties, like '凤凰' and '富士', need strict water control in summer, stop watering in July, provide ventilation and shade, as they are really heat-sensitive.
The above information provides a comprehensive explanation of the overwintering experience of evergreen succulents, hoping it helps you.
