A slow release fertilizer made for junipers, applied lightly, is the best choice, and many junipers only need it when growing in nutrient poor urban or landscaped soil. Junipers are not heavy feeders, so the goal is steady support for their roots and year round foliage rather than a push of new growth.

Why don't junipers need heavy feeding?

Junipers are not heavy feeders and become drought tolerant once established, so a heavy dose of fertilizer isn't what they need. Excess nitrogen works against them, causing weak shoot growth and lowering tolerance to drought, cold, and disease.

When does a juniper benefit from fertilizer?

Mostly in nutrient poor urban settings, where soil is often compacted and poor. In a landscape like that, a light feeding matched to the species supports root development and disease resistance.

What should a juniper fertilizer contain?

Slow release nitrogen and a mix of macro and micronutrients that support root development and disease resistance, applied lightly below the grass roots near the drip line rather than against the trunk. In a nutrient poor yard, working TreeHelp Premium Fertilizer: Juniper into the soil at the drip line gives the roots a steady supply through the growing season without pushing soft new growth.

Frequently Asked Questions

Can fertilizer fix yellowing on a juniper?

Not always. Spider mites cause yellowing and stippling of the foliage, and phomopsis tip blight, a fungal disease, causes the growing tips to die back, so neither is a nutrient problem.

What soil does a juniper need?

Well drained soil above all. Junipers tolerate sandy, loamy, and rocky soils as long as water doesn't sit around the roots.

How should a juniper be watered after feeding?

Sparingly. Letting the soil dry between waterings suits a juniper, with regular watering needed during dry spells, especially for young plants.

Should a juniper be fertilized in summer?

Not with a fertilizer high in nitrogen. Applied in the middle or end of summer, it pushes weak new growth that can be damaged in winter.
