have done it. the problem is not what type of soil is in the pot, the problem is you water the potted plants, over a very long time, the minerals and chemicals will deposit in the pot, that's the reason for the rings you can see on the ceramic or terra cotta pots. you won't see the mineral rings on plastic pots, but it does not mean it's not there. of course, you can repot and change out the soil every year, like many companies do with their indoor plants, or just throw out the bad looking one
【在 S*A 的大作中提到】 : 这个你是听说的还是知道实际情况是这样的? : 盆装的花土壤用的不是一般地里的土。你去买 pot soil 和 top soil : 是不一样的。 pot soil 里面基本上没有什么粘土。 : 我自己对种花不是很在行,但是我注意看过我们公司里维护那些 : 室内大盆的花的园丁干活。好多年了,重来没有把整盆泡到水里的。 : 浇水剪枝是有,还有用一种我不知道的液体化肥,装在自己的罐子 : 里,看不出来是什么。 : 事实上,这样泡我很担心会淹死。

I see, you have very hard water and the calcium build up in the pot. I can buy that. Do you know your CH level in your tap water? I know mine is about 180 or so, it is consider hard. Between my swimming pool and fish tank, I have many water test kits. I guess you can use water softer treat it before you give it to your plant.
minerals rings repot and change out the soil every year, like many companies do with their indoor plants, or just throw out the bad looking ones, and get the good looking
