Before you begin

Quick-start checklist.

Apply only where soil can absorb water.
Avoid saturated or frozen soil.
Place the spike along the tree’s drip line.

Keep the trunk and root flare clear.
Continue appropriate watering and mulch care.
Address severe compaction or drainage problems separately.

Do not assume Part C is compatible with the bucket-and-spike system. Confirm compatibility in the exact product’s approved directions.

Part A · Bucket & ground spike instructions

Liquid concentrate

Install the spike
Drive the ground spike into the soil along the tree’s drip line.
Position the bucket
Set the bucket securely on top of the spike.
Mix & fill
Add 2–4 fl oz of concentrate per gallon of water and fill the bucket. The diluted mixture slowly drips into the soil in the feeder-root zone.
Refill with water
After the bucket empties, remove it from the spike or leave it in place. Refill with water only 1–2 times per week. During drought, refill twice weekly.

Use only where soil can absorb water. Avoid saturated or frozen soil.

Part B · Separate root-zone soil amendment

Charged biochar add-on

Check the biochar
Use the approved biochar product and site-specific amount. Confirm soil suitability and charged status before application.
Prepare separately
If charging is needed, follow the approved charging protocol. Keep biochar separate from the liquid concentrate and bucket-and-spike system.
Place in the root zone
Follow the site plan for placement under mulch or approved soil incorporation. Keep away from the trunk and do not bury the root flare.
Cover & maintain
Cover with mulch as directed. Continue appropriate watering and soil care. Avoid heavy piles; address compaction separately when needed.

Follow the approved protocol for charging, amount, treated area and incorporation depth.

Part C · Fresh-added biological application

Dry biological packet

Check the product
Use the exact approved Part C product and rate. Confirm expiry and suitability for the tree. Keep dry until application.
Prepare for application
Follow the approved product directions. If liquid mixing is specified, dilute Part A first, then add Part C immediately before use. Do not add to the concentrate jug.
Place in the root zone
Use the product’s approved placement method to reach the active root zone. Confirm bucket-and-spike compatibility before using that system.
Use promptly
If liquid mixing is approved, stir gently but thoroughly and apply promptly. Keep shaded and out of extreme heat. Do not store hydrated biological mixture.

Follow the approved product directions for the exact rate and application method.
