Acidophilic plants

Types of acidophilic plants

Under the denomination of acidophilic plants, all the species that prefer an acid soil with a pH lower than 6.5 are placed. With acidophilic plants we can create beautiful borders or colorful flower beds. Bulbous acidophilic plants will be perfect in this case . We can divide acidophilic plants into 3 main macro categories: trees, shrubs, herbaceous. Among the trees, those that prefer an acid soil and therefore fall into this category, we find silver and red fir, birch, beech, chestnut. They are acidophilic shrubsazaleas, magnolias, hydrangeas, rhododendrons, mimosas, gardenias, heather, blueberries, strawberry trees. Among the herbaceous plants considered acidophilic there are lilies, lilacs, ferns, clivias, calla lilies. Some species of acidophilic plants are also climbers, for example jasmine, ivy and wisteria. We can also make a hedge of acidophilic plants using laurel, bougainvillea or hibiscus.

Soil acidification

A natural method to acidify and fertilize the soil at the same time is the use of recycled grounds from the coffee machine. You can also resort to the use of liquid substances such as the juice of leftover oranges, lemon or even that of tomatoes, trying to use spoiled ones to avoid unnecessary waste. Alternatively, we can purchase a specific product to be administered on the ground in the open field or in pots. For the home cultivation of acidophilic plants, a soil other than the universal one used for vegetables is recommended. The specific soil for acidophilic plants, with more suitable composition characteristics, is very easily found on the market. Fertilization must also respect the acidity parameters, gradually adding mature manure to the earth to make the soil absorb nutrients. Alternatively we can resort to an acid pcciamatura, with bark of trees of this species such as fir and oak.

Soil irrigation and drainage

The soil for the cultivation of acidophilic plants must be previously prepared. In pots we will use the specific soil, soft and light, which will also make the root system develop adequately. In the open field we will have to avoid the areas characterized by the presence of arid clods, working the earth in depth and trying to make it as friable as possible. Watering should be done regularly without overdoing it. We will also have to take into account the seasonality of the rains. Depending on the region we live in, during the wettest periods of the year, atmospheric precipitation may be sufficient. In the event that you have pots placed in sheltered areas, it is advisable to water regularly periodically to avoid water fluctuations. Stagnant water is very dangerous for acidophilic plants. The soil must therefore ensure excellent drainage.

Acidophilic plants: Exposure, climate, diseases

There are acidophilic plants of many varieties and it is therefore impossible to make a general reasoning valid for all of them. Acidophilic plants can be grown both in the plains and in the hills, practically in all regions of Italy. Growing inside pots is better because it allows you to move the plants indoors, in a sheltered place, during the frost season. They need sunlight to develop, but they don’t have to be exposed to full sun. Acidophilic plants should be placed in partial shade. The yellowing of the leaves could be caused both by too much exposure to direct radiation, and by a soil that is not acid enough. In the first case, the exposure should be changed by moving the vase,
