I have a correction to a previous post though with both good and bad news. The good news is that whatever sprouted the first time was NOT the kaffir lime seed but a weed that just happened to find it's way in. The bad news is that it finally did sprout and quickly died as well as the blood orange... I think bugs got to them and, since I don't use pesticides, that can happen.
Below is a picture of the kaffir lime and lemon tree as they are just a few minutes ago.
The lemon tree is doing good even though the destroyer of plants continues to feast on the lower leaves and throw them up wherever he wants to. Hopefully one day he will stop this bad trend and figure out that his stomache just wasn't made to digest lemon leaves.
