Frequently asked questions

Why are my tree's new leaves yellow with green veins?

Iron chlorosis. Pin oaks, river birch, red maple and sweetgum are especially prone in alkaline soil. Chelated iron delivers iron in a form roots can still absorb at high pH.

How long will one bottle last?

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

How do I apply it to a large tree?

Water it into the soil across the whole root zone under the canopy, or use a hose-end sprayer to reach the foliage. Results on new growth show within a few weeks; deep soil pH correction takes longer.

Do I still need a regular fertilizer?

Yes. This targets one shortfall; your regular feed supplies the nitrogen, phosphorus and potassium that drive growth. Use the two together.

How do I apply it?

Water it into moist soil at the labeled rate, or use it as a foliar spray in the morning or evening for a faster response on the leaves.

Which plants need it most?

Pin oak, river birch, red maple, sweetgum and magnolia are the most common cases, along with anything showing the deficiency signs above. It suits edible and ornamental plants alike.

When will I see results?

Deficiency symptoms ease on new growth within two to three weeks; leaves that are already damaged will not recolor, but the next ones will come in healthy.
