Indoor potting mix for scented geranium

Asked September 6, 2016, 11:44 AM EDT

Hi, Would you kindly recommend an indoor potting mix (sterile) for house plants/ scented geraniums? I am familiar with the fertilization and watering and care. My problem has been that the soil I've been using gets bugs. I usually buy from a nursery- all purpose ABS and amend with fertilizer/ perlite/ vermiculite Etc based on the plants needs. Thank you so very much!

If you are noticing gnat like insects flying around your houseplants then you are most likely referring to fungus gnats. The larvae breed in moist soil rich in organic matter, primarily in potted plants. They feed on the fungi in the soil. Overwatering contributes to the growth of the fungi. Allow the top several inches of soil in your containers dry before watering again. Also, do not allow the pot to stand in water or for water to accumulate in pot saucers.

We recommend a soilless mixture for houseplants. This mixture is usually a mix of peat moss, perlite, and vermiculite. We do not have recommendations for specific brands. You can look for seed starting mixtures and some nurseries sell bales of commercial seed starting mixtures.
