Master the art of the perfect substrate: free guide to take care of your plants like a pro The substrate is the heart of any plant. Beyond light and watering, it is the base where roots develop, nutrients are stored and the balance between water and oxygen is maintained. Choosing or preparing a good substrate can make the difference between a plant that simply "survives" and a small ecosystem that thrives in a healthy way. Whether you grow houseplants, succulents, aromatic plants or an urban garden, knowing how to create the right substrate allows you to adapt the mix to the real needs of each species. That's why we at Domestika have prepared a free download: a PDF inspired by the course "Designing green spaces for your home". A practical guide to understand the soil, customize it and take care of your plants like a pro. What is a substrate and why is it so important. The substrate is the mixture where the roots grow. Its main function is to retain water and nutrients, but also to allow air to circulate freely. This balance is essential for plants to breathe, absorb minerals and grow strong. A poorly chosen substrate can cause: - Excess moisture → fungus and rot. - Lack of aeration → suffocated roots. - Nutrient imbalances → yellow leaves, poor growth or lack of resistance. Knowing the materials and proportions is key to healthy and sustainable growth. What you will find in this free download. The guide includes: - Types of substrates for indoor, succulent, aromatic, urban garden and tropical plants. - Essential components: peat, coconut fiber, perlite, vermiculite, compost, coarse sand, bark.... - Recommended proportions to balance humidity and aeration. - Tips for reusing used substrates and enriching them. - Recommendations to keep the mix fresh, light and free of fungi. An indispensable guide to creating and maintaining a sustainable green environment.
