Product Information
Ferti-lome Root Stimulator & Plant Starter Solution 4-10-3
Help new plantings establish faster with a concentrated starter solution designed to support early root development and reduce transplant stress.
Ideal for trees, shrubs, flowers, roses, and houseplants during planting or transplanting.
Why Use
Promotes early root growth for quicker establishment
Helps reduce transplant shock after planting or repotting
Supports healthier starts with a starter nutrient blend (4-10-3)
Great for landscape installs, garden beds, and container plants
When to Use
At planting time for new trees, shrubs, and flowers
When transplanting seedlings or moving plants to new locations
During repotting for houseplants and container plants
After weather stress or handling that may cause transplant shock
Retreatment
If plants are slow to rebound, reapply as a soil drench in 2–3 weeks (follow label directions).
For ongoing establishment support, repeat only as needed while plants are actively rooting.
Avoid excessive retreatments on stressed plants; consistent moisture and good planting depth matter most.
Once plants are established (about 4–6 weeks), transition to a balanced fertilizer program.
Pro Tips
Water the planting hole first, then apply the diluted solution to improve root-to-soil contact.
Keep soil evenly moist (not saturated) for the first few weeks to encourage strong rooting.
Mulch lightly around new plantings to stabilize moisture and temperature, keeping mulch off the stem or trunk.
Important Notes
Always read and follow the product label for exact mixing rates, application amounts, and use directions.
Do not apply to drought-stressed plants without correcting watering first.
Store tightly closed in a cool, dry area.
