plants fail to germinate?

when i try to plant plants in the round pots (base game) i keep getting this notice that they fail to germinate. some plants will get planted and some won't but none of them are trees or carrots or things that wouldn't make sense to be in a planter, for example trying to plant strawberries and they won't germinate but onions will. wondering if anyone else has had this problem/if there is a fix? hoping to plant on planters on the porch instead of in the ground. thanks!
