How to Speed Up the Growth of Your Houseplants

Watering with club soda

Club soda is basically carbonated water, which is rich in various macronutrients that will boost the growth rate of your indoor plants. Different research studies have proven that houseplants that are regularly watered with club soda will outgrow those watered with tap water because of the same. As a precaution, however, ensure to let your fizzy club soda go flat before applying it on your houseplants.

Applying Old Coffee Grounds

If you have indoor plants that do well in acidic soil, such as miniature roses, pouring old coffee grounds on the potted soil on which the plants grow will help boost their growth rate. This is because coffee is rich in various minerals that are beneficial to plants, including phosphorus, calcium, and nitrogen. You can apply coffee grounds by either applying them directly to the base of your houseplants, or incorporating them into the compost mix.

Applying DIY fertilizers

If you’re working on a budget and are looking to save on the cos of commercial fertilizers, you can combine various household ingredients to make your own fertilizer. For instance, you can combine Epsom salt, household ammonia, and baking soda to create homemade fertilizer. Such homemade fertilizer is typically slow-release and will boost the growth rate of your houseplants without harming them due to excess salts building up in the soul.
