What's Inside

The 3-3.6-5.1 ratio is weighted toward flowering and fruit rather than heavy leaf growth, which suits a tree grown for its crop and its form. Phosphorus at 3.6% and potassium at 5.1% both outweigh nitrogen at 3% — olives are naturally lean feeders, and too much nitrogen drives soft growth at the expense of flowers and fruit. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low in the well-draining soil olives need.

Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what strengthens wood and new growth — magnesium (0.75%), iron, boron, copper, manganese, and zinc. Boron matters especially for olives, where a shortfall is a common cause of poor fruit set, and the micronutrients keep the characteristic silver-green foliage healthy.

Made For

Every olive tree (Olea europaea): fruiting varieties like Arbequina, Manzanillo, and Mission, fruitless ornamental types grown for foliage and form, and dwarf and potted olives — young trees, established specimens, and indoor or patio containers in cooler climates.

Problems It Solves

  • Poor flowering or light fruit set
  • Yellowing or pale foliage instead of healthy silver-green
  • Slow growth on young or newly planted olives
  • Weak establishment after transplanting or potting

FAQs

How often should I feed my olive tree?

Every 1–2 weeks during spring and summer while it's actively growing, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) keeps feeding light and steady — olives are naturally lean feeders, so this gentle consistent approach suits them better than heavy applications.

Do olive trees need much fertilizer?

Less than most fruit trees. Olives evolved in poor Mediterranean soils and are adapted to lean conditions, so the goal is steady light feeding, not heavy nutrition. Over-feeding — especially with high nitrogen — pushes soft leafy growth at the expense of flowers and fruit, so this formula's gentle, bloom-weighted ratio is a better fit than a strong all-purpose feed.

Why isn't my olive tree fruiting?

Several reasons are common: young trees aren't yet mature enough, olives need a period of winter chill to flower, and many benefit from a second variety nearby for good pollination. Boron shortfall can also limit fruit set, and it's in the formula. Feeding supports the tree, but chill, maturity, and pollination are often the deciding factors.

Will this burn my tree?

No — at the directed dilution, the formula is designed for regular use. All-nitrate nitrogen and low salt concentration make burn very unlikely, even on young or potted trees. For newly planted olives still establishing, start at half strength for the first two feedings.

When will I see results?

New growth greens up within the first few weeks of feeding during the growing season. Olives grow slowly and steadily, so vigor and foliage color respond first; flowering and fruiting follow the tree's own cycle and maturity over seasons.
