Here's the scoop on p**p! We barely touched on this topic last week, so here's part doo! (ahem, part #2).
You may have noticed an accumulation of small piles of pellets on your garden leaves. Scout for the culprit. This is likely caterpillar p**p! Caterpillars p**p A LOT, especially when they're feeding so heavily this time of year.
Caterpillar frass is enormously beneficial for soil. It improves soil structure and quality and triggers plant immunity as well by protecting against pests and fungal diseases. Frass feeds good soil bacteria and microorganisms which increases its biological activity and helps strengthen root development. Frass also contains slow-release nutrition for plants through its natural mix of nitrogen, phosphorus and potassium.
The more caterpillar frass you see, the better. More caterpillars mean more butterflies and moths! More butterflies and moths mean more birds and bats in your yard! It's all about the frass...
Plant native for a diverse life cycle in your own backyard!
