For outdoor Bonsai we recommend using a relatively high Nitrogen content fertilizer like NPK 10:6:6. in spring, a more balanced fertilizer like NPK 6:6:6 is more optimal for summertime, and a low Nitrogen fertilizer like NPK 3:6:6 for autumn.
2. Can I use fertilizer on bonsai?
Bonsai plants and trees are grown in limited amounts of soil which means it requires regular feeding than most houseplants and ornamental plants. During the growing season, your bonsai trees should be fed weekly with bonsai fertilizer. Your bonsai may stop absorbing nutrients during late summer and early fall.
3. How do you fertilize a bonsai tree?
The nutrients are washed out of the soil through normal watering, so liquid bonsai fertilizers should be applied every three to six weeks in the off season. When applying, pour the liquid bonsai fertilizer directly over the leaves and allow it to drip into the soil.
4. Can I use all purpose plant food for bonsai?
Use a slow or continuous-release fertilizer on your bonsai tree. Generally, fertilizers rich in phosphate, nitrogen, and potassium will benefit bonsai and keep them strong and healthy. Formula-wise, we recommend either a pellet or liquid plant food option to use on your tree, so it gets as many nutrients as possible.
