- prevents waterlogging
- including fertilizer depot and minerals

Mix rhododendron soil yourself - this is how it works
If you don't want to buy rhododendron soil, mix it yourself by making your own compost and mixing soil with flowers. Your new rhododendron or offshoot in the garden will feel right at home in it. Make sure that the pH value is never exceeded or fallen below. Dose the fertilizer for the rhododendron soil so that the pH value remains around 5.0.
Good to know: Substitutes added to peat-free soil bind nitrogen. Natural clay should therefore be added to the soil as a nutrient and moisture buffer. By adding sand, heavy garden soils such as clay soils are sustainably improved. Sand with a little charcoal or firewood ash avoids numerous Fungal diseases.
Tips & Tricks
Humus is one of the most nutritious garden soil. So fill the site with a 20 to 30 centimeter layer of humus before inserting the rhododendron. As excavated soil, you get humus particularly inexpensive for construction work or earth moving.
Throw excavated humus through a sieve before spreading it!
