Aphids can be a big problem for many baneful plant allies, and they are particularly problematic for henbanes and deadly nightshades here in Texas. Even what the plants are grown indoors, aphids are still prevalent.
A light dusting of diatomaceous earth (DE) on the plant is a good non-toxic way to get rid of these pesky pests. It is a bit messy because DE particles are super fine and can go everywhere. And you need to reapply after rain or if the plant gets wet.
I usually use a neem oil spray, especially for indoors applications because it’s a little less messy than DE. And the spray stays on the plant a little longer than DE. You can buy ready-to-use neem oil spray at most garden centers or nurseries. I make my own these days because it’s much cheaper. Neem oil can be purchased at health food/natural health product shops, and you can easily get it in bulk through Amazon.
To make your own neem oil spray, check out this recipe:
- 1 tsp of neem oilΒ
- 1/2 tsp of liquid dish soapΒ
- 1 quart of water
OR
- 4 tsp of neem oil
- 2 tsp of liquid dish soap
- 1 gallon of water.Β
Shake well before use. Spray the diluted solution generously on all leaf surfaces and base of the plant.
Neem oil mixes easier with warm water. I usually mix the neem oil and soap first before adding water. If the temperature is cooler than 76F, neem oil will solidify. Simply warm the spray (or the pure neem oil) in a double-boiler method and it should return to a liquid state.
