Fig trees are not heavy feeders. In reasonable soil, an established tree may need very little fertilizer, and too much can do more harm than good.
What to use
A balanced general-purpose fertilizer, such as 8-8-8 or 10-10-10, is usually suitable if your tree needs feeding. Compost or well-rotted organic matter is also a gentle way to improve soil. Follow the rate on the product label.
Does your tree need it?
- Look at growth: a healthy tree producing about a foot of new growth a year may not need any.
- Watch for signs: pale leaves or very weak growth can suggest a shortage of nutrients.
- Test your soil: a soil test takes out the guesswork. Your local extension service can help.
The risk of too much nitrogen
Excess nitrogen encourages lots of leafy growth at the expense of fruit, and it can lead to fruit dropping early or ripening poorly.
When to feed
Feed in early spring as growth begins. Avoid feeding in late summer, since soft new growth is easily damaged by cold.
Young and potted trees
- Young trees: small amounts split across the growing season can help them establish.
- Potted figs: nutrients wash out with watering, so they usually need more regular light feeding.
Water well after fertilizing, and add a layer of mulch to retain moisture. Keep track of feeding with our Seasonal Home & Garden Planner.
