Frequently Asked Questions
How do I know if my tree needs fertilizer?
Look at the annual growth at the tips of the branches. If the tree is putting on 6 to 12 inches of new growth each year, it is likely doing fine without extra food. If the growth is stunted or the leaves look pale, a light dose of fertilizer might be helpful.
Can I use liquid fertilizer on my maple?
You can, but liquid formulas act very quickly and disappear just as fast. They are better suited for container-grown maples where the soil volume is limited. For trees planted in the ground, slow-release granules are much more reliable and require less work.
What happens if I accidentally use too much fertilizer?
Too much fertilizer leads to root burn, which shows up as scorched leaf edges or sudden leaf drop. If you suspect an overdose, flush the soil thoroughly with a garden hose to leach out the excess salts. Avoid adding any more fertilizer for at least a full year.
Should I fertilize a newly planted tree?
Avoid fertilizing a tree during its first year in the ground. The tree needs to focus its energy on root establishment rather than pushing out new foliage. Wait until the second spring after planting before you start a regular feeding schedule.
Do Japanese maples in pots need more fertilizer than ground trees?
Yes, potted trees lose nutrients every time you water them because the minerals wash out of the drainage holes. You should use a diluted, balanced fertilizer at half the strength recommended on the label during the growing season. This ensures the tree stays nourished without the risk of accumulating salts in the small container.
