When your trees and shrubs may benefit from feeding

  • When your actively growing landscape shrub has a confirmed nutrient deficiency that supplemental feeding can address
  • When your container-grown tree or shrub has used the limited nutrients in its potting mix over time
  • After your newly planted tree or shrub is established and growing, if a soil test shows nutrients are lacking
  • When your maintained hedge is producing new foliage and documented soil conditions support supplemental nutrition

Established landscape trees often need no fertilizer. Yellowing, browning, or thinning can signal water, root, light, or disease problems instead.

What's inside
The 3.6-3-5.1 ratio is built for woody plants that need both top growth and root strength. Nitrogen at 3.6% fuels canopy and new shoots, and potassium at 5.1% — the highest of the three — drives root development, drought tolerance, and the wood strength that keeps trees and shrubs standing through stress. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low, which matters most for newly planted stock still building roots.

Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what strengthens cell walls and new root growth — magnesium (0.75%), iron, manganese, zinc, boron, and copper. These are what keep foliage deep green and evenly colored rather than pale or yellowing between the veins, the first sign a tree or shrub is running short.

Frequently asked questions

How often should I feed my trees and shrubs?

Every 1–2 weeks during spring and summer while they’re actively growing, and every 4 weeks in fall and winter, at 2 tablespoons per gallon of water. Tree and Shrub Fertilizer is a liquid, so it goes into your regular watering and reaches the roots right away. Steady feeding matters most for newly planted stock, which establishes faster on consistent light feeding than on occasional heavy applications. A hose-end sprayer on the 1-ounce setting covers larger plantings in a pass.

Can I use this on newly planted trees and shrubs?

Yes. Tree and Shrub Fertilizer is built with new plantings in mind. All of the nitrogen is nitrate, which developing roots absorb directly, and the formula leads with potassium at 5.1%, the nutrient that drives the root development establishment depends on, backed by 2.1% calcium for new root growth and strong cell walls. For the first two feedings on fresh transplants, start at half strength, then move to the full rate as your plant settles.

Will this work on both deciduous and evergreen shrubs?

Yes. Tree and Shrub Fertilizer is a woody-plant formula that suits deciduous trees and shrubs, broadleaf evergreens like boxwood and azalea, and flowering shrubs like hydrangea and lilac. Its 3.6-3-5.1 ratio supports both canopy and roots, and the magnesium and iron keep foliage evenly green across the mix. TPS makes dedicated evergreen and acid-loving formulas that fine-tune for specific groups, but for a mixed landscape this one covers the whole planting on one schedule.

When should I stop feeding for winter?

Move to every 4 weeks through fall, then ease off before hard dormancy. Late-season nitrogen pushes tender growth that won’t harden before frost, so the last feedings of Tree and Shrub Fertilizer should come while your plant still has time to firm up. Resume in early spring as growth breaks. This matters most in cold-winter climates; in warmer zones, trees and shrubs keep growing longer and can stay on the lighter fall schedule further into the year.

When will I see results?

New growth typically comes in greener within the first few weeks of regular feeding, since Tree and Shrub Fertilizer is a liquid with nitrate nitrogen the roots absorb directly. Trees and shrubs grow slowly, though, so filling out a thin canopy or establishing a young plant takes a full season or more. Color and vigor respond first; size follows over time as the roots and wood build on the potassium and calcium in the formula.
