What flowers and trees are suitable for planting in acidic soil?
Soil is the foundation for the growth of soil-grown plants. Every plant has different soil requirements; they don't just take any soil. You need to consider fertility and pH level, among other things. So what flowers and trees are suitable for planting in acidic soil?
What flowers are suitable for planting in acidic soil
Every time an important holiday comes around, someone always jokes about “shopping till you have to eat dirt”, and some simply say they can't even afford to eat dirt anymore. Joking aside, some elderly people really did have a history of surviving on dirt, and dirt isn't something you can just eat any way you like - you have to eat it scientifically. Plants eating soil also has its rules: only by finding soil that suits them can they grow healthily. The south is rainy and humid, and the soil is mostly acidic. Generally speaking, flowers native to the south are all suitable for planting in acidic soil, such as rhododendrons, gardenias, jasmine, camellias, southern magnolias, cyclamen, lilies, begonias and orange jasmine, among others.
1. Rhododendron
Only this flower follows the Yue bird; where it cries, the whole mountain turns red. The rhododendron that dyes the mountains red, also known as yingshanhong, is a typical indicator plant of acidic soil in China's central-south and southwest regions. In the south it is mainly planted in the ground, while in the north it is mainly grown in pots. It likes acidic sandy soil and also likes acidic water.
When watering rhododendrons, try to choose acidic soil; if the water quality does not meet the requirements, ferrous sulfate or vinegar can be added for acidification treatment.
2. Gardenia
Gardenias are planted in most parts of the country, concentrated in East China, Central-South China and Southwest China, which are exactly the areas where acidic soil is concentrated. Gardenias like fertile, loose sandy loam. If the soil and water contain high alkaline components, it will affect the plant's absorption of iron, causing the leaves to turn yellow or even die. Yellowing leaves are a common problem encountered with flowers, so you might as well drip a few drops of vinegar into the water when watering.
3. Camellia
Camellia is one of China's top ten traditional flowers. It originated in eastern China and likes slightly acidic mountain red (yellow) soil, with pH 5.5—6.5 being optimal.
4. Orange jasmine
Orange jasmine, also known as yuzilan or mizailan, originated in South China. Its flowering period is from May to December, and the flowers are yellow. Orange jasmine likes a warm and humid environment and has weak cold tolerance. When the temperature is below 16 degrees Celsius, growth slows down, and when the temperature approaches zero degrees, the whole plant will die; it is suitable for growing in slightly acidic sandy soil.
What trees are suitable for planting in acidic soil
Now that we've covered what flowers are suitable for planting in acidic soil, let's look at trees. Most flowers can be grown in pots, and through improving soil pH, they can also be grown in pots in the north. Trees, especially large trees, are mainly planted in the ground and are more dependent on the native soil. Trees suitable for planting and growing in acidic soil include tea trees, Elaeocarpus sylvestris, ginkgo, deodar cedar, Japanese white pine, fir trees and tung trees.
1. Tea tree
Anyone who has studied tea knows that tea trees are suitable for growing in soil with a pH of 4.5—6.5, and China's famous teas are mostly produced in the hilly areas of the southeast. The sap in tea tree roots contains some organic acid substances and has a strong buffering capacity against acidity, which is an important reason why tea trees like acidic soil.
2. Elaeocarpus sylvestris
Elaeocarpus sylvestris is a subtropical tree species and an evergreen tree. From autumn and winter to early spring, some of its leaves turn crimson, making it highly ornamental. Elaeocarpus sylvestris has strong adaptability and likes acidic soil. It grows vigorously in acidic yellow soil and red-yellow soil.
3. Ginkgo
At present, ginkgo is cultivated and planted in many places across the country, so much so that many people have forgotten its noble status. It is a rare relict tree species from the Mesozoic Era, even older than the “once upon a time” that appears in ordinary fairy tales. It grows slowly and has a long lifespan, making it the old longevity star among trees. This old longevity star has a relatively wide adaptability to soil and can grow in both acidic soil with a pH of 4.5 and calcareous soil with a pH of 8.
4. Fir tree
Fir tree is the collective name for plants in the Taxodiaceae family, with 15 species in total, such as those in the genera Cunninghamia and Metasequoia. Fir trees are common building materials and are suitable for growing in acidic yellow soil, red soil and yellow-brown soil.
It is not only humans who love soil deeply; plants are even more dependent on soil. When planting plants, everyone must clearly understand the soil properties and the growth habits of the plants - what is suitable for planting in acidic soil, what is suitable for planting in alkaline soil, which flowers like acidic soil, and which trees prefer alkaline soil.
