I'm not quite sure how you'd end up laning against Ashe, but if you're up against her, you won't be able to harass her at all unless she messes up, as she outranges you. The same applies for most ranged champions, including/especially more "meta" top laners like Lissandra or Kennen. In those cases, try to get jungler help, and if you end up too far behind, play passively, farm until 6 and go help out other lanes.

Against Yi, though, if you get harassed purely by his Q, try to catch him as he exits Alpha Strike, and if you can't, just let him push to your tower without trying to harass him, where you'll be a lot safer. Jungler ganks will help a lot against him as well, and if not you can bait his abilities until he's low on mana, whereupon you can dunk him fairly easily.

More generally, harassing enemies as Darius is a matter of using the minion wave to your advantage: hover around the enemy cannon creep, and when your target moves in to last hit, time your Q so that they're forced to either take damage or lose CS. If they use ranged abilities, try to catch them within range of your E, which puts them in a bad spot. If they outrange you completely, you will not be able to harass and will have to either get jungler help or just abandon your lane to snowball the others. In matchups like these, I recommend you take Teleport, which will help you recover and gank other lanes much quicker.

With Darius, any opportunity to harass can lead to an all-in past level 3: if you're comfortable with your health level and your enemy's, you can follow your Q up with an E + autoattack + W combo and force an all in, or at least an advantageous trade. If you started with E, continue with the auto + W + auto combo and then follow up with Q, or cast Q immediately after W if you just want to deal a burst of damage and retreat.

As for landing your Q edge more often, it really just come down to practice. Anticipate where your enemy's going and move with them if they're in range. Don't be afraid to step outside of your minion wave, because your Q won't trigger enemy minions, but also be careful with creep block, as it can mess up your pathing.
