How often should I fertilize my pot plants to ensure optimal growth and vitality? Is there a specific schedule I should follow, or does it depend on the type of plant I am nurturing? Are there signs that indicate my plants are in need of additional nutrients? For instance, should I consider factors such as the season, the age of the plant, or the type of soil in which they are potted? Given the myriad of fertilizers available, should I opt for organic options or synthetic ones, and how do their application frequencies differ? Furthermore, is it essential to adapt my fertilization regimen during different growth phases, like flowering or dormancy? What about the environmental conditions—do temperature, humidity, and light exposure affect the fertilizer requirements? Could over-fertilizing be as detrimental as under-fertilizing, and how can I strike the perfect balance for my indoor green companions?
