Lol. When it comes to keeping houseplants, I’m like that. Last year we managed to let a couple of succulents die. They needed to be watered like once every two weeks or so, but sometimes we completely forgot for 4 weeks, and sometimes we watered them twice a week. They didn’t survive very long - lol
Belgium is a ‘rainy’ country, so all plants that are outside only need watering during a heatwave, which we don’t get that often.
Maybe you should consider an ‘automated’ self-watering system... Then you just need make sure the main source of water doesn’t dry out
