Flower Fertilizer - Ferrous Sulfate
The editor will talk about some common knowledge of flower cultivation, focusing on flower fertilizer - ferrous sulfate. Here is a comprehensive introduction to follow.
Ferrous Sulfate Fertilizer
1. Performance Features: Adjusts soil pH, promotes the formation of chlorophyll (also known as iron fertilizer), can prevent and treat yellowing disease caused by iron deficiency in flowering plants, and is an essential element for acid-loving plants, especially for iron trees.
2. Usage, Dosage, and Control Objects
(1) Usage: ①. Mix 10 grams with 4-5 pounds of water, and spray on the foliage. ②. Apply once or twice a month during the normal growing period. ③. During the disease prevention period, apply once every 10-15 days, for 2-3 consecutive times.
(2) Dosage: Mix 10 grams with 7-9 pounds of water, and water the potting soil, about once every 20 days.
(3) Disease Control and Principle: Mainly treats yellowing disease. Symptoms include: initially, the leaf flesh turns yellow on young leaves, followed by browning spots appearing on the sides, center, or tips of the leaves; over time, the leaves fall off. Principle: Adjusts soil pH, conducive to the normal growth of acid-loving plants.
3. Suitable Plants: Various acid-loving flowering plants, such as: iron trees, azaleas, camellias, michelias, hanging orchids, bamboo, white orchids, poinsettias, five-needle pine cypresses, jasmines, ferns, palm trees, and various potted plants and盆景. Due to the fact that most soils are "south acidic and north alkaline," garden plants originally from the south often use ferrous sulfate for adjustment when transplanted to the north.
4. Precautions: Do not use in excess. If burning of the seedlings occurs due to excessive use, please use the following methods:
①. If sprayed: Sprinkle clean water repeatedly on both sides of the leaves. ②. If watered: Water the potting soil multiple times.
