Due to their different places of origin, potted plant green plants have great differences in their needs and adaptability to acidity and alkalinity. Most types of potted green plants are suitable for neutral to slightly acidic soil (pH value 5.5~7.0), within which the trace elements needed by potted plant green plants are in a digestible state. Outside this range, some trace elements become indigestible, causing some potted plants to become malnourished.

Potted plants can be divided into the following categories according to their adaptability to strongly acidic or alkaline soil:

(1) Acid-tolerant potted plants (pH value 4~5) include rhododendron, hydrangea, gardenia, coleus, purple ageratum, ferns, orchids, etc. (2) Acidic potted plants (pH value 5~6) include begonia, amaryllis, cyclamen, camellia, oleander, madrona, modest smile, pentas, pines, palm plants, primroses, daffodils, and hibiscus. (3) Neutral or slightly acidic potted plants (pH value 6~7) include chrysanthemum, lilyturf, asparagus, poinsettia, osmanthus,吊钟花, orchid, narcissus, chrysanthemum, begonia, etc. (4) Neutral or slightly alkaline potted plants (pH value 7~8) include rose, rose, German iris, geranium, forsythia, bupleurum, osmanthus, daphne, lily, begonia, crape myrtle, grape, wisteria, cacti, sweet peas, alkali flowers, and补血草.

Plants that prefer pine needle soil

In our daily life, there are many common plants that prefer pine needle soil. Below are several plants that many people keep at home.

Rhododendron

Rhododendron likes to grow in pine needle soil, so many people regard rhododendron as an indicator of pine needle soil. If there are rhododendron growing around your home, it indicates that the soil around is acidic.

Camellia

Camellia likes to grow in loose, fertile, thick, slightly acidic or alkaline soil layers, with a pH value of about 5~6 being enough. It should not be planted in alkaline soil layers.

Plants that prefer alkaline soil

In daily life, there are not many plants that prefer to grow in alkaline soil layers. Below, let’s talk about what plants prefer to grow in alkaline soil layers.

Pomegranate

Pomegranate prefers to grow in loose, fertile, organically rich, slightly alkaline soil layers, and it has a strong adaptability to the environment, with high tolerance to low temperatures, drought, and barrenness, making it a plant that is easy to maintain.

Lotus flower bud

Lotus flower bud is a kind of plant that can grow in soil layers with not too many green plants, and it can grow and develop in soil layers that are either sour or alkaline. In addition to sour or alkaline, it is most suitable to plant it in loose, fertile, well-drained, and thick soil layers.
