How to grow flowers and bonsai without soil? Detailed technical process

Soilless cultivation of flowers and bonsai can be carried out in any season. Soilless cultivation can make flowers grow rapidly and robustly, bloom more and earlier, larger and more fragrant, and resist cold and tolerate heat, with fewer pests and diseases. The specific operation steps for soilless cultivation of bonsai are introduced below:

1. Prepare the nutrient solution: Dilute the soilless cultivation nutrient solution sold on the market with water according to the specified multiple. You can also prepare the nutrient solution yourself with the following formula: ① Macroelements: potassium nitrate 3 grams, calcium nitrate 5 grams, magnesium sulfate 3 grams, ammonium phosphate 2 grams, potassium sulfate 1 gram, potassium dihydrogen phosphate 1 gram; ② Microelements: (use chemical reagents) disodium ethylenediaminetetraacetate 100 mg, ferrous sulfate 75 mg, boric acid 30 mg, manganese sulfate 20 mg, zinc sulfate 5 mg, copper sulfate 1 mg, ammonium molybdate 2 mg; ③ Tap water 5000 ml (that is, 5 kg). Prepare the macroelements and microelements into solutions separately, then mix them together to make the nutrient solution. The amount of microelements used is very small and not easy to weigh, so they can be prepared in an expanded multiple and then extracted in the same reduced multiple. For example, the microelements can be weighed out at 100 times the amount and made into a solution, then 1% of that solution is extracted, which is the required amount. The nutrient solution is non-toxic, odorless, clean and hygienic, and can be stored for a long time.

2. Remove from the pot: Use your fingers to push the root system together with the soil out through the hole at the bottom of the pot.

3. Wash the roots: Soak the soil-covered root system in water close to the ambient temperature, and wash the soil from around the roots.

4. Soak in solution: Place the washed roots in the prepared nutrient solution and soak for 10 minutes so they fully absorb nutrients.

5. Potting and pouring in the solution: Wash the flower pot, place a tile piece or plug plastic gauze in the hole at the bottom of the pot, then put a small amount of perlite and vermiculite into the pot, next place the plant into the pot and hold it upright, then fill lightweight minerals such as perlite and vermiculite around the root system, and gently shake the flower pot so the minerals and root system are in close contact. Immediately pour in the prepared nutrient solution until liquid flows out from the hole at the bottom of the pot.

6. Reinforce the root system: Place fragments such as fluorite and ax-split stone on top of the root system to reinforce the roots and prevent lodging. At the same time, spray some clean water on the leaves.

7. Daily management: For flowers and bonsai grown without soil, the requirements for light, temperature and other conditions are no different from those for soil cultivation. During the growing period, water the plants with nutrient solution once a week, with the amount depending on the size of the plant; for flowers whose leaves grow slowly, reduce the amount as appropriate; in winter or during the dormant period, apply once every half month to one month. Indoor foliage plants can survive under low-light conditions, so the amount of nutrient solution should be reduced. The nutrient solution can also be used for foliar spraying. Usually, pay attention to watering at the right time.

Generally, the easier-to-cultivate indoor and outdoor flowers and bonsai include Monstera deliciosa, Aglaia odorata, Clivia miniata, camellia, Chinese rose, jasmine, rhododendron, kumquat, lily-of-the-valley shrub, violet, Phalaenopsis, fuchsia, five-needle pine, banana shrub, rubber fig, Dracaena fragrans, begonia types, ferns, palm family plants, and so on.
