HI I was just wondering after i bareroot my lemon tree to my grit mix how often do i water, because it drains really well or do i feel the top of the pot 1 to 2 inches from top?
Intervals between waterings are going to vary according to weather conditions, soil ingredients, soil mass:root mass, whether you screened the ingredients in a way that allows you to get the most from the soil, how well the roots have colonized the pot ...... IOW, there's no way to tell. Fortunately, it's really difficult to over-water a properly made gritty mix, which greatly increases your margin for error.
Immediately after repotting, you'll want to make sure the top part of the soil remains moist, to promote fastest root reestablishment ..... especially if you chose a pot considerably deeper than the root mass. After a week or two, you can feel the soil at the drain hole to determine when it's appropriate to water. If the soil feels damp or wet at the drain hole, withhold water until it feels dry.
