Conclusion
Houseplants such as peace lilies, pothos, and fiddle leaf figs can be fed an eco-friendly and cost-effective fertilizer made from wood ash. Reusing untreated hardwood ash from fireplaces or stoves can produce a potassium-rich fertilizer for gardens, which enhances stem strength, leaf health, and flowering. Sifting wood ash to remove pollutants and then storing it in an airtight, dry container are steps in the procedure that guarantee safety and potency. You can grow plants indoors without using pesticides by diluting ash into a wood ash solution or mixing it with compost or perlite.
