What Plants and Flowers Are Not Suitable for Ferrous Sulfate
For most women, the knowledge about what plants and flowers are not suitable for ferrous sulfate in terms of gardening is provided in the detailed introduction below.
What Plants and Flowers Are Not Suitable for Ferrous Sulfate
Plants that are not suitable for watering with ferrous sulfate include roses, lilacs, forsythias, crape myrtles, acacias, white waxwings, hibiscus, pomegranates, and more. Ferrous sulfate is particularly unsuitable for these alkaline-loving plants, as its use may result in delayed blooming, yellowing, and drying of leaves, which is detrimental to the normal growth of the plants.
Pros and Cons of Watering Flowers with Ferrous Sulfate
1. Benefits
Ferrous sulfate has two main functions in home gardening: it improves the soil's pH level, making it more suitable for flower growth, and it supplements iron, preventing the leaves from yellowing, falling off, or withering.
2. Hazards of Incorrect Use
Using an improper amount of ferrous sulfate can cause black spots on the plant's leaves and, in severe cases, accelerate the yellowing of the leaves, leading to more leaf fall.
Moreover, excessive application of ferrous sulfate can result in excessive iron nutrition, causing widespread leaf drop and withering due to excessive acidity in the root environment.
Which Flowers Are Not Suitable for Ferrous Sulfate
Roses
Roses are not suitable for ferrous sulfate because they prefer to grow in alkaline soil. Ferrous sulfate increases the soil's acidity, which is not conducive to the growth of roses.
Lilacs
Lilacs belong to the Myrtaceae family and also prefer alkaline soil, so they are not suitable for ferrous sulfate. Typically, we can dry the flowers of lilacs and then soak them in warm water for five minutes to drink, as they have high medicinal value.
Forsythias
Forsythias have high requirements for their growing environment and bloom from March to April, and bear fruit from July to September. If watered with ferrous sulfate, the flowers will quickly wither, and it may even cause the entire plant to die.
Crape Myrtles
Crape myrtles produce beautiful flowers and are known as "century reds." They bloom from June to September and bear fruit from September to December. Do not use ferrous sulfate when cultivating crape myrtles, as it will cause the leaves to yellow and repeated applications may even lead to the death of the plant.
Acaias
Acaias are strong-lived plants belonging to the Fabaceae family. They have unique flowers that are loved by many. However, acacias are also not suitable for ferrous sulfate, as it will reduce their ornamental value.
White Waxwings
White waxwings do not have high requirements for their growing environment and can be grown in pots with high ornamental value. However, if watered with ferrous sulfate, it will stimulate the roots of the white waxwings, affecting their normal growth and potentially preventing them from flowering, so do not use ferrous sulfate.
Hibiscus
Hibiscus belongs to the Malvaceae family. If grown in alkaline soil, it will grow quickly and produce bright and beautiful flowers. If watered with ferrous sulfate, it will grow slowly.
Pomegranates
Pomegranate flowers are very beautiful and typically bloom in May. If watered with ferrous sulfate, not only will the flowers of the pomegranate quickly wither, but the number of fruits produced will also decrease, affecting the growth of the plant.
