Experts please chime in!
I planted Nasturtium as a "trap crop" for aphids in my city garden. They're already getting covered by these little black critters (assuming they're aphids), but the Nasturtium haven't even bloomed yet. I am sad to think that I should be pulling these plants already, so I have been researching what beneficial insects are higher on the food chain? What critter can I attract that will eat the aphids? Answer: LADYBUGS.
So... my question is: Other than providing a buffet of aphids, how do I attract ladybugs?
Has anyone ever used wheast? It's apparently a mixture of equal parts yeast and sugar added to water that is like potato chips for our speckled little friends.
