I have two small flowering ornamental cherry trees. I have had them for a few years growing in large pots. This year, as always, they both flowered beautifully, but I noticed over the weekend they both have a clear jelly like substance on the branches. Their branches also have quite a bit of lichen on them. Please can you tell me what action I should take to clear this problem? I have never seen the jelly before. Thank you.

It might be bacterial wetwood, peach borers or canker, depending on how the sap looks (though I'm leaning on borers as you say it's clear and jelly like). These articles will describe the nature of the running sap for each problem and will suggest solutions:
