Question about making crosses.
I have been looking at a lot of posts and videos regarding how to cross tomatoes. Some of the growers cover their emasculated blossoms while some don't. In fact, more don't cover them than do. Actually, they state that if when emasculating a blossom you remove the sepals, petals and anther that there will be nothing left to attract bees or other insects and so no need to cover. This makes sense to me and would make things a lot easier but I was wondering what some of you more experienced with this are doing?
