The Garden Academy Rhineland Palatinate, whose website gartenakademie.rlp.de published on behalf of the Ministry of Environment, Agriculture, Food, Viticulture and Forestry, has in its publication "The glossy medlar - a fashion shrub?" With the glossy medlar (botanical Photinia) employed. She has found that it is precisely the evergreen varieties of the loquat that are not "hardy" or "frost sensitive" - which is quite logical, because most evergreen plants develop in areas with a consistently warm climate, and the classical ones Photinia come from the warm part of Asia, India and Thailand.
Plants in cold winter regions, on the other hand, are more likely to reduce their nutrient requirements to zero by leaf-shedding (and other mechanisms) in the cold period. Although some of the Photinia species have also considered this, these species, too, naturally grow on the edge of the Himalayas or in eastern Japan, and thus in areas where little minus degrees are known.
- Most will be fine Photinia X fraseri (in many varieties with beautiful names like "Camilvy", "Curly Fantasy", "Cassini" and "Red Robin"), Photinia glabra, Photinia serratifolia and Photinia davidsoniae which the garden academy consistently classifies as very frost-sensitive or not hardy at all.
- Also the Photinia davidiana with names like "Palette" and "Prostrata" (honest, author can not help it) and the Photinia nussia are well-known sales stars, but are considered very fire risk, which is why their cultivation in Switzerland is prohibited and is not recommended in our country.
The gloss medlar in the tubAfter all just mentioned considerations, the ideal location of a gloss medlar is actually in the bucket on the terrace, where a deciduous variety may also overwinter with protection (the evergreen gets a bright and frost-free winter quarters).
As already mentioned, the usual cut of a Photinia is limited to clearing after flowering, as a rule, the plant has so much "stress" with us, that you should rather let her have any strength. However, if the delicate plantlet throws off its leaves due to waterlogging or dryness, it may only form new leaves on the branches that will re-grow and otherwise remain bare. Then only a radical cut will help - actually you would put such an unwilling plant "on the stick", so cut down to the ground, but since nowhere to find information about whether a Photinia tolerate that, you should this "new creation" For safety reasons, spread the plant over several years.
