The frequency of watering and fertilizing plants is dependent on a combination of factors including soil composition, water retention, and environmental conditions. Different soil types have varying capacities to hold water, impacting how often they need to be watered. For example, sandy soils drain quickly, requiring more frequent watering than clay soils, which retain water longer. Environmental factors like sunlight, temperature, and humidity also play a significant role, with plants in warmer, sunnier environments generally needing more water and potentially more frequent fertilization.
There is no one answer to that question.
The simplest and most effective fool proof way of understanding when to water and when to fertilize is to use a soil ec metre. Electrical Conductivity requires both water and salt.
Ec is the currency of life, if it's not happening in the soil nothing is going up.
Pop your stick in if it's low then you add water and take a new ec reading, if it's where you want it to be after watering you add more salts.
