What fertilizer does Wei Zi bonsai use?

Wei Zi bonsai should pay attention to the coordinated application of nitrogen, phosphorus and potassium fertilizer. During the growth period, apply dilute water-soluble Bika fertilizer every 15 ~ 20 days, and apply nitrogen fertilizer after each pruning or leaf picking to promote the growth of budding new shoots and branches. Apply phosphorus-based fertilizer from flower bud differentiation stage to civilization stage, and provide nutrients needed for making flower buds and flowering in time.
