My girls are doing well so far this year, probably thanks to our California like weather this year. All sunny days and little to no rain. These plants are watered by a drip irrigation system, although when I applied the granular fertilizer, I watered it in by hand. Each plant has its own dripper depositing at least one gallon of water per hour.
Watering systems by Drip Depot. I did also apply one shot this week of Bonide Thuricide which is a biological control for caterpillars (aka, BT).
