Aphid Mini-Experiment Update & Conclusion

2.5 weeks since last Neem Application

One week after application I squished 5 aphids.  Today I squished two.  Before the Neem application the aphids were in abundance up to 10 per leaf.  I declare this an effective solution!

The Purple Passion shed its three biggest leaves after the application.  Because of this I recommend using Neem on somewhat mature plants.  However it is growing and looking very happy.  It lives alone on the back of the toilet, a lively area of the house with a window.  I think the plant likes the attention, encouraging it to repel the aphids.  The only other plant in the room hangs above.  I purposefully secluded the Purple Passion so the aphids do not spread to any other house plants.

There was a true lady bug in the living room yesterday;  a beneficial insect who loves to eat aphids!   So the next time I see one she’s going right on the Purple Passion.


  • Keep an eye on water levels!  The Neem Oil was mixed with water so I didn’t think to give the Purple Passion a watering until I saw it drooping.  It doesn’t normally get watered every week.  The Neem could have played a part in this, but I honestly don’t know how.
  • I considered washing the Neem off of the plant at one point, but since its growing and happy there is no need.
  • My mother has observed aphid’s preference for wooly or fuzzy leaves.  Purple Passion is in that category and I would also admit to Sage’s adherence.


Neem Oil makes for an effective solution to Aphid infestations on house plants!

Use 100% sustainable and organic Neem Oil for your formula.

Mix 1/2 dropper in 6-12oz of room temperature water and pour over or spritz the affected plant, both on top and under each leaf.

—>You could do your own experiment, starting with less Neem Oil and seeing how much it takes to rid the Aphids on your particular plant.  A way to conserve your supply.

Shower your plant with encouragement and love during treatment!


ps – since beginning this post yesterday, I have found red spider mites and possibly their adult black counterparts on several of my houseplants, and they are in the sunniest room in the house!  Also, I have had several house-mouse sitings, and for every one you see…

Look for experiments to follow!!!  I suppose before the plants come out from hibernation I must tend to the critters who wake-up first.
