D. oleifera is a tropical foliage plant of the palm family originating in Madagascar. It is warm and humid and has low cold resistance. It requires loose, fertile, well-drained acidic and semi-acidic soils. The phenomenon of chlorotic chlorosis on the lower leaves of your dilltail plants can be used for the following reasons:
One is that the basin soil is too viscous, causing some roots to rot at the tip.
Second, the air humidity is too low, or potting and soil consolidation, resulting in some roots do not absorb enough water, causing the middle and lower old leaves first yellow aging.
Third, the soil acidity is not enough, affecting the absorption function of the root system. You can take the plants out of the pots and check carefully to see if there are any rotten roots. If rotted roots are found, cut off the rotted parts; then use rot-leaf and peat to add 1/5 of the sand. And a small amount of transparent cake fertilizer, formulated into a complex nutrient soil, to change the pot. In the conservation process, keep the room temperature not lower than 5°C in winter and have good light, and sprinkle water around the plants; when the weather is dry in summer and autumn, we should keep the basin soil moist and spray water on the leaves. Sprinkle water around the plants in order to increase the humidity of the air. In the summer, it must also be properly shaded to avoid direct sunlight. In addition, it is also possible to fertilize a thin cake fat every 30 days, add a small amount of ferrous sulfate, in order to provide nutrients for the plant, while adjusting the pH of the soil to meet the normal growth of the need for diffusa.
