Field Notes
How Long Do Predatory Mites (and Other Beneficials) Work?
The lifespan on the label is not what decides how a release goes. What does is whether the beneficials leave, starve, dry out, get cold or get sprayed. Here are the lab lifespans we could find, and what nobody has measured yet.
What Makes a Leaf Blister?
Sometimes the bump is the leaf itself. The science of blisters and corky spots is more interesting than “you watered too much.”
Can Beneficials Help With Root Knot?
There are promising results—and inconvenient ones. Explore what the studies actually tested before turning biological control into a shopping list.
Protecting Your Collection From Root Knot
Fresh mix does not reset an infected root system. Trace the shared water, tools, and plant material before deciding what to save.
Inside a Root-Knot Gall
The bump is plant tissue. The parasite is inside. Start with what root-knot actually means before choosing a treatment.
Finding the Roots Worth Saving
Start with what is still firm and alive. A root-inspection and salvage guide before another bottle goes into the pot.
Spend a Day With a Curling Leaf
A leaf that folds at noon and a leaf that grows twisted are telling different stories. Watch the sequence before choosing a fix.
A Fresh Look at Brown Tips
An old brown tip cannot report on today’s care. Follow the water, check the salts, and learn what improvement actually looks like.
Moving Into the Light
The leaf was built for its previous address. Explore what changes when a plant gets more light—and why equal daily totals can hide very different peaks.
Follow the Yellow Leaf
Before the fertilizer comes out, find out which leaf changed first. A guided investigation of yellow leaves and the stories they can tell.
Californicus or Persimilis?
One of them clears a heavy infestation faster than anything else available. The other one is still there in a month.
Water by the Pot, Not the Calendar
Your plant has no idea what day it is. Here is how to read the pot, follow changing water demand, and make a watering decision that means something.
