Analysis of the Causes of Dead Orchid Seedlings in Chinese Cymbidiums and Prevention Methods
Orchid seedlings develop scorched tips, yellow leaves, yellow leaf sheaths, rotten hearts, rotten roots, and rotten pseudobulbs, and eventually the entire plant dies, causing huge economic losses to investors in fine Chinese cymbidium varieties. Orchid enthusiasts have different opinions, and only when cultivation becomes difficult does one truly understand orchids. Investigation and analysis show the main causes: First, excessive fertilizer. Chinese cymbidium cultivation media should be lean rather than rich; when mixing, do not worry that fertility is insufficient and add too much fertilizer-heavy medium. If the growing soil is found to be too rich, it should be replaced promptly or technically treated. During Chinese cymbidium management, if the plants can grow normally relying on the medium, there is no need for extra

Reasonable flower and fruit thinning of bayberry (Chinese bayberry, Myrica rubra) promotes stable and high yields
Bayberry (Chinese bayberry, Myrica rubra) bears fruit mainly on short and medium fruit branches. Because on these two types of bearing branches only the terminal bud is a leaf bud, while the rest mostly differentiate into flower buds, if they are allowed to set fruit naturally, they often bear excessively, the fruits are small and of poor quality, and it easily causes alternate bearing. To achieve stable and high yields, fruit thinning should be carried out. (1) The thinning period is generally in mid-to-late April, after fruit set is determined and before the fruits rapidly swell. (2) Thinning method: out of every 6 bearing branches, keep 3 to bear fruit and thin out 3, and each fruit-bearing branch keeps 2 fruits. (3) Thinning principle: keep fewer on the upper part of the canopy and more on the lower

What is anthracnose in Chinese orchids? Let us learn about this disease
Anthracnose in Chinese orchids affects orchids of the genus Cymbidium such as Spring Orchid (Cymbidium goeringii), Faber's Cymbidium (Cymbidium faberi), Four-season Orchid (Cymbidium ensifolium), Chinese Cymbidium (Cymbidium sinense), and Cold Orchid (Cymbidium kanran), causing scorched black spots on leaves and fruits, and in severe cases the entire leaf dies.
