What is going on guys and girls out there in the world wherever you are?

Hopefully you are having a nice little walk,

0:08.0

sipping some coffee, whatever you're doing, welcome back to the Epic gardening show.

0:12.0

And today I'm going to cover a topic

0:13.8

that I think a lot of people would like to know about because I know that I

0:17.2

wanted to know about it when I first started gardening and that is how do we

0:21.9

take potting so that we've already used maybe last season

0:25.9

maybe we just want to switch it out grow a new plant but we don't want to waste that

0:30.4

1:21.0

And of course, all plants use most, most all 17 nutrients that they need, but they do use them in different

1:26.7

ratios.

1:27.7

Something like a lettuce is going to be a lot more heavy in nitrogen than something like a tomato

1:30.9

that's going to use a lot more phosphorus than a lettuce plant
