Which Pots Should Not Be Used for Planting Flowers
Beginners in flower cultivation are often enchanted by the dazzling flowerpots, not knowing that choosing the wrong container might lead to the slow death of their beloved plants! Pots made of different materials directly affect root respiration and moisture circulation. Today, we delve into the hidden dangers of five common types of flowerpots through comparative experiments and gardening cases.
One, Pots with Lethal Breathability
1. Plastic Pots: A Typical Example of a Beautiful Trap
The popular colored plastic pots on the market are light and cheap but are a hidden killer for succulents, orchids, and other fleshy-rooted plants. Experimental data shows that the condensation water retention time on the inner wall of plastic pots is three times longer than that of ceramic pots, easily causing root rot. It is recommended to use volcanic stone as a base and check the roots monthly.
2. Glazed Ceramic Pots: An Elegant Cage with Difficulty Breathing
The high-temperature firing glazed layer completely seals the pores, making it only suitable for water-cultivated plants like green pothos. A gardening blogger found that the mortality rate of Monstera deliciosa in glazed pots is 47% higher than in coarse ceramic pots, and the yellowing speed of the leaves is twice as fast.
Two, Special Material Pots Prone to Wear and Tear
3. Wooden Pots: A Culture Dish for Mold
Untreated pine pots expand and crack when in contact with water, with a 60% decrease in structural strength within two years. The humid environment is prone to wood-rotting fungi; one user reported that their mint plant suddenly withered in the wooden pot, and upon excavation, the roots were completely moldy.
4. Metal Pots: Temperature Regulation Disaster
After being exposed to the hot sun, the surface temperature of wrought-iron pots can reach 60°C, directly burning the fine roots close to the pot wall. In winter, they quickly lose heat, causing double damage from frostbite. The measured temperature fluctuation is more than four times more intense than that of ceramic pots.
Three, Flower Pot Taboos for Special Plants
Air plants must not use any sealed containers, as积水 will rot; Phalaenopsis orchids must use transparent pots to monitor the roots; carnivorous plants need special pots with an opening rate of over 70%. Experienced flower friends share: after switching to a red ceramic pot, the number of blooms of the desert rose increased by three times!
Selecting a pot is essentially creating a miniature ecosystem, where the number of breathing holes is more important than the material. When buying a pot next time, please first feel the inner wall to see if it is rough, estimate the weight of the pot, and check the drainage design, allowing each plant to breathe freely!
