Show #113 - Tree Planting Season: Why Fall Is the Best Time to Grow, Feed, and Strengthen Your Landscape

Fall Tree Planting Season: Nature’s Root Growth Celebration

It’s tree planting time!
As we move past October 22nd, all plant and tree energy shifts underground. This marks the beginning of the root growth season, when 80% of trees’ and lawns’ roots grow during the six coldest months of the year.

Now is the time to fertilize heavily, plant wisely, and prepare your landscape for long-term success.

The Power of November Feeding

  • November feeding boosts root growth by 200–300%.
  • Ideal fertilizers include:
    • Fertilome’s Start-n-Grow (19-6-12)
    • Anderson’s (18-6-12)
    • Plant trust on Turf Trust (excellent for lawns and trees)

Pro Feeding Tips

  • Apply fertilizer up to the trunk but keep it 1 inch away from contact.
  • Always place fertilizer under the mulch to stay moist on dry days.
  • Forget the “drip line” myth — feed close to the trunk for best results.

Supercharging Flower Bud Set

Many trees and shrubs are only performing at half their potential. Heavy food, water, and mulch dramatically increase productivity — especially for Dogwoods, Peonies, Lilacs, and Rhododendrons.

Pro Tip: Super Phosphate Magic

  • Use Super Phosphate (0-45-0) granules in the root zone, not on top.
  • Drill or stake small holes into the root ball, drop in 3 tablespoons, and water deeply.
  • One application lasts 15 years and transforms growth buds into flower buds.

Also, remember to pinch new growth tips (not trim!) once they reach ½” to encourage branching and even more blooms.

Feeding Rules by Tree Type

  • Evergreens maintain foliage all year, so their root balls are 60% larger and they need 60% more fertilizer than deciduous trees.
  • Lawns and trees get 1½ times a normal feeding rate; shrubs and perennials get a standard rate.
  • After feeding, mulch and apply Gallery to prevent 150+ types of winter weeds for 9 months.

Why Fall Is the Best Time to Plant Trees

Planting trees in fall means:

  • Cooler temperatures = less water stress.
  • Nature does the watering as roots grow all winter.
  • By spring, your trees are established and thriving.

Fun Fact: Plants Grow by Color Speed

  • Red grows the slowest.
  • Pink grows faster than red.
  • White, lavender, and purple grow the fastest.

This color-speed rule applies across many plant families — from azaleas to trees.

This Week’s Garden Checklist

  1. Bring in tropicals and annuals before frost. Spray Summit’s Green Armor ($9.88) to repel insects — one spray lasts up to 7 washings.
  2. Fertilize and lime your lawn: Heavy feeding and 40 lbs of lime per 1,000 sq ft correct pH and discourage weeds.
  3. Add iron boosters like Preferential Treatment for deep green color and improved root growth.
  4. Keep leaves off shady lawns: They block sunlight and smother grass. Try the Catchy Can ($54.44) for fast leaf cleanup.
  5. Plant fall color: Pansies, violas, cabbage, and kale add instant brightness.
  6. Add buried treasures: Plant bulbs — tulips, daffodils, crocus, and hyacinths — for spring blooms.
  7. Refresh containers: Add pansies or dwarf evergreens for winter interest.
  8. Control weeds: Use Fertilome’s Weed Free Zone down to 45°F with Wilt-Pruf. For tough weeds, Decimate works in cold weather when Round-Up won’t.

Final Thoughts

Fall isn’t the end of the gardening year — it’s the beginning of next year’s success.
Feed, plant, and protect now, and your trees will reward you with strong roots, vibrant growth, and incredible blooms all spring long.
