its such a shame that the good word of "stop using 5-7-5" has not been spread to most of the haiku posters of cohost.
See https://www.nahaiwrimo.com/why-no-5-7-5 for information about why your 5-7-5 haikus are actually too long for a haiku (and also it may be impeding your creativity)
It's a strong case.
A minor cavil: English limericks typically count beats but not, within certain tolerances, syllables. Wikipedia says they do, but you can 80%+ assume anything Wikipedia tells you about prosody is wrong. In this case the various examples on the page itself show variation in offbeats; the very first example has six syllables in its third line and five in its fourth line ('But the good ones I've seen | So seldom are clean'), even though the two lines are metrically equivalent.
As for things to do instead, this is my approach, trying to find something equivalent to some aspects of Japanese form in its constraints and its reliance on perceptible features of the language in question (here: English). I'm sure there are many other things we could be doing too.
I spent a few years writing a "haiku" daily and with a handful of serendipitous exceptions, never followed the 5 7 5 rule.
As the image above points out, to me, the most important part of a haiku is the seasonal image. Another extremely important part is the cutting word, which is of course much more difficult in English so I didn't always try that.
If you really want to explore haiku, the best resource I can think of is Kodansha's edition of Bashō's haiku (yes that Kodansha). I've taught from it before. The book includes lovely translations and then all the poems again in kanji, romanji, and literal translation. You can see what's actually going on in the original even if you aren't exceptional at Japanese (I am certainly not).
To end, regarding what @thaliarchus said about English language features, I largely have ended up using head rhyme in all my poems based on these years of writing haiku, as that's one of the more "natural" (a loaded description) features of the language.
