The revision which would make the sentence more precise is the following one:

We can say the sentence above works as a "translation" of the original one. That said, let's check it out:

I would like to give you my thoughts:  I would like to share my ideas and thoughts.

In the context, the verb to give means to share, and the noun thoughts, in plural form, means opinions, ideas ).

...on this organic gardening movement: on the latest news on organic gardening.

The movement mentioned can be described as the effort some people have been doing towards organic gardening, and since people in general are likely aware if it, it becomes "the latest news".
