The "Little Valve" of Epipremnum aureum
Epipremnum aureum, as a representative of indoor foliage plants, always amazes people with its explosive growth. Many enthusiasts find black stripes on the branches of Epipremnum aureum and mistakenly trim them, thinking they are diseases. In fact, these are the plant's "growth accelerators" — aerial roots. This article will delve into the mysteries of aerial roots and guide you step by step on how to achieve the spectacular scene of Epipremnum aureum covering a wall in three months through scientific care.
Core Function Analysis of Epipremnum Aureum Aerial Roots
Natural Nutrient Converter
Aerial roots are the unique aerial root system of Epipremnum aureum, covered with absorbent epidermal cells that can efficiently capture over 80% of the free water molecules in the air. In an environment with humidity above 60%, a single aerial root can absorb up to 5ml of water per day. This special structure gives it dual nourishing functions: absorbing nutrients from the air and converting water into plant growth hormones.
Multiplier for Cutting Success Rate
Stems with aerial roots have a 73% higher survival rate compared to ordinary stems. In hydroponics, aerial roots can quickly develop into water roots, while in soil culture, they transform into underground roots. Experimental data shows that stems with aerial roots take 5-7 days less to root and have a 40% higher germination rate of new buds.
Practical Guide to Activating Aerial Roots
Water Control to Promote Rooting Method
The "Little Valve" of Epipremnum Aureum
Using the "dry-wet alternating" care method: when the soil moisture drops to 30%, the leaves will show slight wilting, at which time aerial roots will sprout in large numbers. Maintaining air humidity above 70% and combining foliar application of 0.1% potassium dihydrogen phosphate solution can stimulate the proliferation of aerial roots.
Climbing Induction Technique
Set up a pole or grid支架 for the branches. When the vines touch the support, the contact point will differentiate into aerial roots within 48 hours. Regularly wrap the pole with a wet towel, and after the aerial roots adhere to the moist surface, their daily growth rate can reach 2-3cm.
Detailed Explanation of the Full Process of Aerial Root Cutting
Hydroponic Rapid Scenery Method
Select a 15cm stem with 3-5 aerial roots, keeping the aerial roots submerged 2-3cm in water. Add 2 drops of HB101 vitality essence when changing water weekly, and keep the water temperature around 25°C. New roots can be seen after 7 days, and a complete water root system can be formed in 20 days.
Soil Culture Explosive Pot Technique
Use a mixture of peat soil and perlite in a 3:1 ratio and disinfect with a carbendazim solution before planting. Bury the aerial roots 1cm deep in the matrix, maintain an ambient temperature of 18-28°C, and use the bagging method to keep the moisture. The survival rate can reach over 95%.
By scientifically utilizing the characteristics of aerial roots, combined with moderate water control and support induction, Epipremnum aureum can achieve a growth rate of 3-5cm per day. Mastering the secrets of activating aerial roots and cutting, combined with monthly application of a special foliage plant fertilizer, it is no difficult task to create a Epipremnum aureum plant wall in three months. Remember: healthy aerial roots are the key signal for Epipremnum aureum's explosive growth, and they should not be mistaken for diseases.
