Preparation for watercress cultivation 

Preliminary preparation for watercress cultivation 

Soil selection for watercress

Watercress has higher requirements for soil selection, and semi-soft planting materials are preferred. For weak seedlings: the root system is still unstable, and for the purpose of root cultivation, it is best to choose plant materials with low fertility. For example, you can mix granular raw red soil, thorn millet leaves, burned soil and rotten pine needles in a ratio of 3:4:1: Mix at a ratio of 2.

For strong seedlings: the most important thing is growth and flowering, so the proportion of millet leaves can be appropriately increased to improve soil fertility. The ratio of granular red soil, millet leaves, burned soil and rotten pine needles is 2:61:1 mix in proportion.

Pot selection for watercress

It is better to choose a plastic basin with good air permeability, and a ceramic basin is also acceptable.

Pruning of watercress plants

Select watercress that grows vigorously and robustly, rinse the orchid roots with clean water, then use sterilized scissors to cut off the dry rotten roots and black roots, then soak the orchid plant in diluted potassium permanganate for half an hour and take it out. Place in a cool place to air dry.

Water supply of watercress

Watercress has average water resistance, so it should not be watered too much during the maintenance process, and water should not accumulate. When the soil surface is dry, just pour a small amount of water to moisten the pot surface. In summer, the pots are generally moistened every other day and watered thoroughly twice a month. In autumn, the pots are moistened twice a week and watered thoroughly once a month. Control the amount of water in winter and moisten the basin once a week.

Light management of watercress

The growth of watercress requires a long photoperiod, proper shading is required in summer and autumn, and no shading is required in winter and spring. Insufficient light may cause the watercress to bloom less easily, so you need to pull the watercress out and dry it in the sun more often.

Temperature and Humidity Control of Watercress

Douban Orchid likes warm winters and cool summers. The optimal growth temperature is 15-28°C. You don’t need to pay too much attention to the temperature in spring and autumn. In summer, the temperature exceeds 35°C and it grows slowly. It can be cooled by shading and spraying. In winter, the temperature is lower than 10°C. ℃ needs to be moved indoors to prevent frostbite. The suitable air humidity is 70-80%, and the suitable humidity in winter is 50-60%.

Fertilizing measures for watercress

The watercress cultivation medium is rich in nutrients, so there is no need to apply chemical fertilizers during the cultivation process. Mix an appropriate amount during the annual repotting or soil replacement process. Cake fertilizer or sheep manure can provide sufficient nutrition for watercress, and generally no fertilizer is applied in between.

Ventilation Management of Watercress

Watercress in In a well-ventilated environment, the respiration of orchid plants is promoted, metabolism is accelerated, and growth is promoted; if the ventilation conditions are poor, it is easy to cause bacteria and mold to multiply in large quantities, causing rot and mildew, which is not conducive to the growth of orchids. The choice of a well-ventilated place must be sufficient. Consider the wind force and avoid damaging the blades due to strong winds or cold winds.
