Evergreen Fertilizer for Deep Green Growth

Evergreen Fertilizer

Evergreens hold their foliage year-round but make most of their new growth in one spring flush, and that is the window our liquid Evergreen Fertilizer is for. It supplies the nutrients pines, spruces, firs and broadleaf evergreens use for new needles and shoots, in the landscape or in large containers, by can or hose-end sprayer.

“I’ve used TPS Evergreen fertilizer for two seasons now. I have a wide verity of evergreens including: Cedars, Hemlocks, Spruces. Applying in the fall and spring keeps them healthy (pest free) and rich in color. Living in a highly clay soil area TPS is economic solution to ensure health growth.”

When your evergreens may benefit from feeding

When your younger evergreen enters its spring growth period and a soil test indicates available nutrients are low

If your evergreen has produced unusually short new needles or sparse shoots and you've ruled out drought, pests, and root injury

When your established evergreen grows in very sandy soil and testing confirms nutrients have been depleted

If a conifer hedge has adequate light and moisture but a soil analysis identifies a nutrient shortage during active growth

Healthy evergreens often need no extra fertilizer. Browning or needle drop isn't proof of deficiency, and pushing late tender growth can increase winter injury.

What's inside

The 3.6-3-5.1 ratio is built for plants that hold their foliage year-round and keep growing when others go dormant. Nitrogen at 3.6% fuels dense needle and leaf growth and deep green color, and potassium at 5.1% — the highest of the three — drives root strength and the cold-hardiness evergreens rely on to come through winter intact. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low.

Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what strengthens new growth and root structure — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Iron and magnesium matter most here: a shortfall shows as yellowing or bronzing needles, the first sign an evergreen is running hungry.

Frequently asked questions

How often should I feed my evergreens?

Every 1–2 weeks in spring and summer while they’re actively growing, and every 4 weeks in fall and winter. Evergreen Fertilizer mixes into your regular watering at 2 tablespoons per gallon, or a hose-end sprayer on the 1-ounce setting for hedges and larger trees. Evergreens hold their foliage and keep growing through more of the year than deciduous plants, so consistent light feeding suits them better than a single heavy application.

My evergreen's needles are yellowing — will this fix it?

If the yellowing is a nutrient shortage, yes. Yellowing or bronzing needles usually trace to low iron or magnesium, and Evergreen Fertilizer supplies both alongside nitrate nitrogen the roots take up directly, so new growth comes in dark and healthy within a few weeks. Evergreens don’t shed and replace foliage the way deciduous plants do, so badly discolored needles may not fully recover; the canopy fills back in as new growth comes on over the season. If the cause is drought, winter burn or root damage, water deeply and address that first.

Should I feed evergreens in winter?

Yes, on the reduced schedule of every 4 weeks. Evergreens keep their foliage and stay mildly active year-round, so a light winter feed with Evergreen Fertilizer supports them without pushing tender growth that cold would damage. Our formula leans on potassium, which supports the root strength and cold-hardiness evergreens rely on to come through winter intact. In very cold climates, ease off during hard freezes and resume as conditions moderate.

Will this burn my trees?

Evergreen Fertilizer is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water, or granules piled at the base of a trunk. Mixed at 2 tablespoons per gallon and applied every 1–2 weeks in the growing season, the nutrients arrive in solution at a strength the roots take up as they water. For newly planted or transplanted evergreens still establishing, start at half strength for the first two feedings.

Can I use it on hedges and potted evergreens?

Yes, at the same dilution. Evergreen Fertilizer is formulated for the whole group: pine, spruce, fir, juniper, arborvitae, cypress and yew, plus broadleaf evergreens like boxwood, holly and rhododendron. Hedges benefit from steady feeding to stay dense, and container evergreens need it most, since potting mix loses nutrients with every watering faster than ground soil does. Use the watering can rate of 2 tablespoons per gallon for pots and the hose-end sprayer for hedges and large trees.

When will I see results?

New growth typically comes in greener and fuller within the first few weeks of regular feeding. All of the nitrogen in Evergreen Fertilizer is nitrate, the form roots absorb directly, so the color response arrives first. Density takes longer: evergreens grow slowly, and filling in thin or bare interior branches takes a full season or more of consistent feeding. Expect the color to change first and the fullness to follow.
