What kind of soil do flowers prefer? Understanding the different types of soil

Flowers are a beautiful addition to any garden, balcony, or room. They delight us with their fragrance, beauty, and variety. But for flowers to thrive and bloom, their soil preferences need to be considered. Not all plants respond equally to soil acidity, moisture, fertility, and structure. In this article, we'll discuss the soil preferences of different flower species and offer tips on choosing the right soil.

Which flowers like acidic soil?

Soil acidity is a measure of its reaction to an aqueous solution. The lower the value, the more acidic the soil. Acidic soil has a pH below 6.5. Crops that can absorb iron and other micronutrients from the soil thrive in such soil.

Rhododendron

This is an evergreen shrub with large, vibrant flowers that bloom in May and June. Rhododendrons prefer shade or partial shade, moderate watering, and organic fertilizer. They thrive in acidic, light, and well-drained soil.

Azalea

An ornamental shrub with small, abundant flowers in a variety of shades. These plants are suitable for both garden and indoor use. Garden azaleas are planted in shady areas in acidic, fertile soil with added peat or sawdust. Indoor azaleas require good light, away from direct sunlight, and regular watering and misting.
