Tree radish (the scientific name may include different species, such as some species of the Rhododendron family), especially when cultivated as a downhill pile, the following key cultivation methods and precautions need to be noted:
1. Select potting soil and potting:
Use loose, breathable, well-drained soil, mix granular soil, humus, pine needles and base fertilizer in a certain proportion.
Because tree radishes tend to have epiphytic habits, the soil should not be too clay and heavy, and should mimic the humus layer in the natural environment.
Before potting, the pot should choose a material with strong permeability, such as a purple sand pot or a tile pot, and make sure that there are drainage holes at the bottom of the pot
2. Moisture management
Tree radish has strict water requirements and can neither be too wet nor too dry.
Moderate and frequent watering in spring and summer can be replenished when the soil surface is slightly dry, but it is necessary to avoid root rot caused by stagnant water.
Reduce watering in autumn and winter, especially when the soil is completely dry in winter, so as to avoid diseases caused by low temperature and high humidity.
3. Light and temperature:
Tree radishes prefer bright scattered light, so avoid direct sunlight in summer to avoid sunburn on leaves or plants.
Provide a warm growing environment, generally the optimal growth temperature is between 20-28, and in winter it needs to be moved indoors and kept at a temperature of not less than 5.
4. Fertilizer application
Spring and autumn are the period when radish is vigorous, and you can apply well-rotted organic fertilizer water every 15 days or so, or use compound fertilizer containing nitrogen, phosphorus and potassium.
When growth slows down in winter, fertilization should be reduced or even stopped.
5. Pest control:
Regularly inspect the plants for signs of pests and diseases, and deal with any abnormalities in time.
Fungicides can be sprayed in the soil in advance to prevent diseases, and once diseases occur, carbendazim, methyl tobuzin and other agents can be sprayed alternately according to the specific situation**.
Tree radish. 6. Pruning and maintenance
For the downhill pile, it should be pruned in time according to its growth condition to maintain the beautiful plant shape, and at the same time remove the yellow, diseased branches and leaves, which is conducive to the overall healthy growth.
In conclusion, the cultivation of radish piles requires careful attention and proper management, especially in terms of soil, moisture, light, temperature and fertilizer supply, to ensure that the growing conditions are close to their natural ecological environment, so that the radish piles can thrive and form beautiful bonsai.
