What fertilizer should be applied to Philodendron 'Golden Diamond' (Philodendron bipinnatifidum) to make it grow vigorously?
I. Types of fertilizer
The root system of Philodendron 'Golden Diamond' is sensitive. If a strong fertilizer is applied, it can easily burn the roots and cause health problems, so the fertilizer used for it should be a mild fertilizer, or animal manure can be used instead of fertilizer. When using fertilizer, a compound fertilizer can be chosen; compound fertilizers are easy to absorb and have diverse nutrients. Using these fertilizers will make the plant grow vigorously.
II. Fertilization time
The timing of fertilizing Philodendron 'Golden Diamond' depends on the specific situation. If fertilizing in summer, summer is the plant's growing season, when its demand for nutrients is relatively high, so it should be fertilized once a week. Winter is its dormant period, so you cannot fertilize according to the growing season; once every half a month is enough.
III. Precautions
1. Fertilizing distance: When fertilizing Philodendron 'Golden Diamond', the fertilizer must not be applied directly on the roots; it should be 5 to 10 cm away from the roots, to avoid the fertilizer being too irritating and burning the roots. Each time you water, pour the water onto the fertilizer, so that the water carries the nutrients down to the roots and makes it easier for the root system to absorb them.
2. Disinfection after fertilizing: If animal manure is applied, wash your hands and disinfect after applying it, because animal manure contains pathogens.
3. Fertilizing method when the plant is deficient in fertilizer: If Philodendron 'Golden Diamond' shows curled leaves or yellowing leaves, you should consider a fertilizer deficiency. At this time, do not fertilize heavily; you should fertilize little by little, and after its condition improves slightly, return to normal fertilization.
