How often should we water our plants?

daily

alternate day

water when top 1 to 2 inch is dry

study each plant water requirement before watering

depending on season, watering varies

Standard formula of daily and alternate day watering for all plants might not be an option as each plant has different watering requirements.
We need to study each plant’s requirements as some need water daily and some can do without water for months together!!
Plus water requirements for same plant can vary with change of season and when they r in dormancy, ie mostly in winter. So ideally study each plant’s water requirements before u invest in it. The thumb rule for watering is water a plant when top one to two inch soil is completely dry.
