Why do carnations dry from the bottom leaves?
For many girls, here are some small knowledge about why the leaves of carnations dry from the bottom, and the editor will explain it in detail for you next.
Why do carnations dry from the bottom leaves?
1. Improper watering: Excessive watering can cause severe积水 in the soil, leading to oxygen deficiency and root rot in carnation roots. 2. Insufficient light: If the plant is placed in a hidden or poorly lit area, it can affect the photosynthesis of the leaves. 3. Unsuitable soil: The soil is severely compacted, affecting the absorption of nutrients and water by the roots. 4. Over-fertilization: Fertilizing in high temperatures in summer can easily cause fertilizer damage.
1. -- Improper watering --
The root system of a carnation is a fibrous root system. Excessive watering can cause long-term waterlogging in the soil, leading to oxygen deficiency and root rot in the plant's roots, affecting the absorption of nutrients and water, which is not conducive to the normal growth and development of carnations, and thus results in the phenomenon of drying leaves from the bottom.
2. -- Insufficient light --
Carnation is a medium-daylight plant. If the plant is placed in a hidden or poorly lit area during maintenance, it can affect the photosynthesis of the leaves, resulting in insufficient nutrient accumulation, which can cause the leaves of the carnation to rot slowly from the bottom up. It is advisable to avoid intense sunlight.
3. -- Unsuitable soil --
When cultivating carnations, it is necessary to choose loose, breathable, and well-drained acidic soil, preferably heavy loam. If unsuitable soil is chosen or the potting soil is not changed for a long time, the soil can become severely compacted and salinized, affecting the growth of the plant's roots.
4. -- Over-fertilization --
Carnations are sensitive to concentrated fertilizers. Excessive fertilization can easily burn the roots. No fertilizer should be applied to the plants in high summer temperatures to avoid fertilizer damage that causes the leaves of the carnation to dry from the bottom. During the vigorous growth period, it is sufficient to apply a thin, decomposed fertilizer every ten days.
The above sharing is the complete introduction to why the leaves of carnations dry from the bottom, for everyone to learn and understand!
