A bag of potting mix may already contain fertilizer. Adding a full planting dose of something else without reading the bag can give the roots more than you intended.
Start with the labels
Check the medium's stated nutrient charge and the plant's needs. Then read the fertilizer directions for container use, including dilution, frequency, and any seasonal guidance. Products differ; a spoonful is not a transferable dose from one brand to another.
Feeding generally belongs with appropriate active growth rather than being used as a rescue response to every wilt or yellow leaf. Root damage, poor drainage, and inadequate light can prevent a plant using nutrients effectively.
Measure and keep track
Use a dedicated measure and label any mixed solution. Do not use food containers for storage or leave products accessible to children or pets. Keep fertilizers in their original labeled packaging and follow storage instructions.
Record the application date and amount. If the plant later develops trouble, you can assess actual exposure rather than trying to remember whether you fed it twice. A consistent, measured routine suited to the plant is easier to adjust than alternating neglect with a strong dose intended to catch up.
