Guava Tree Fertilizer for Flowering & Fruiting

When your guava tree may benefit from feeding

When a container guava produces new leaves during warm, bright weather
When an established guava begins a healthy seasonal growth flush and soil nutrients are low
When a flowering or fruiting guava has a diagnosed nutrient limitation rather than poor pollination
When frequently watered potted guavas require nutrient replenishment without excess nitrogen

Guava fruiting is affected by light, climate, pollination, and maturity; do not use fertilizer as a substitute for these conditions or feed a slow-growing cold-stressed tree.

How to care for guava trees

Light

Full sun, six to eight hours a day, for the best fruit set. In a pot indoors or in a greenhouse, use the brightest window you have and turn your tree occasionally.

Water

Water deeply through the growing season, letting the top two inches dry first. Even moisture while fruit is swelling keeps it from splitting or dropping early.

Soil

Well drained soil, pH 5.0 to 7.0, with compost worked in. Guavas take a range of soils but not standing water, so raise the planting spot in heavy clay.

Temperature

Happiest between 60 and 85F and damaged below about 28F. In cooler zones, growers keep guavas in large pots and move them under cover for the winter.

Feeding

Feed Guava Tree Fertilizer every two to four weeks through spring and summer while your tree is pushing new growth and fruit, then ease off through the winter months.

Pruning

Prune after harvest to hold your tree at a pickable height and open the center to light. Fruit forms on new growth, so a light yearly trim brings more of it.

Frequently asked questions

How often should I feed a guava tree?

Guava Tree Fertilizer is a liquid feed built to go into your regular watering, so your tree gets nutrition in small, steady amounts rather than a few heavy doses. Feed every one to two weeks in spring and summer, when the tree is growing and carrying fruit, and every four weeks in the cooler months when growth slows. Young trees respond especially well to this steady rhythm as they build the frame that will carry future crops. Once the schedule is part of watering, it stops being a separate chore.

How often should I feed my guava tree?

Every 1–2 weeks in spring and summer while your tree is actively growing and fruiting, then every 4 weeks in fall and winter. Guava Tree Fertilizer is formulated as a dilute liquid, so it mixes into the water you’re already giving the tree at the recommended dilution and the nutrients arrive in solution where the roots can take them up straight away. That steady supply of nitrogen, potassium and the micronutrients guavas run short on suits a tree that flowers and sets fruit over a long season.

Why are my guava leaves yellowing?

If the yellowing sits between green veins on the newer leaves, the usual cause is a shortage of iron, zinc or magnesium. Guavas run short on all three in alkaline or sandy soil, where those nutrients are present but locked up or washed away. Guava Tree Fertilizer includes iron, zinc and magnesium alongside the main nutrients, delivered in solution so the roots can take them up, and new growth comes in green. If the whole leaf yellows, or older leaves drop after heavy rain or drought, check watering and drainage first.

Can I use it on potted and in-ground plants?

Yes. Guava Tree Fertilizer is formulated at one dilution for both, so a potted guava on a patio and a tree in the ground feed from the same mix. Use a watering can for containers and small beds, and a hose-end sprayer set to the recommended rate for larger in-ground trees so the whole root zone is covered. Containers lose nutrients with every watering that drains through, so a potted guava relies on the schedule more than a tree with soil reserves around it.

Will this burn my plants?

Guava Tree 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 the recommended dilution and applied every 1–2 weeks in season, the nutrients arrive in solution across the whole root zone at a strength the roots take up as they water, rather than sitting in one hot spot. If you ever mix too strong, flush the soil with plain water and resume on schedule.

When will I see results?

Foliage answers first. Greener leaves and stronger new growth usually show within a few weeks of steady feeding, as the iron, zinc and magnesium in Guava Tree Fertilizer reach the newest leaves. Flowering and fruiting follow your tree's own season, so the benefit to fruit set and size builds over the months and shows most clearly at the next harvest. Leaves that are already yellow may not fully recolor, but the growth that comes in after feeding begins should be deep green.
