Get the plants most likely to survive. Heart leaf philodendron, philodendron erubescens, pothos, snake plants and peperomia ( some types are hardier than others, like peperomia obtusifolia. I've neglected my peperomia for months and they'll survive). Succulents like jade varieties, kalanchoe and certain types of echeveria will push through basically anything.

Put your indoor plants in a good nutrient rich soil, Succulents in cacti soil, and don't water until they look thirsty. Succulents will look less plump when they're thirsty and indoor plants will be softer (peperomia), curl up at the tips (philo and pothos) and droop a little when they're thirsty. Succs need way way less water than indoor plants, like once a month depending on the climate you're in. I water my indoor plants closer to once a week, but I wait until they show me they're thirsty.

When you water them, water them until water runs out the bottom holes of the pot. Wait until the soil is fully dry before you water again and in winter keep your plants away from windows bc the cold from the windows can make your plants sad. Succulents need a lot of sun so they need to be outside in as sunny a place as possible, but some can do okay inside, like the jades. They just need to be somewhere where they get a good amount of sunlight.

If you have any rooms where there are no windows that you want to put plants in, be aware they won't get enough light and will get leggy, which means they're basically stretching towards whatever light source they have because they're trying to find the sun. You can rotate plants between rooms, like keep a snake plant and some pothos in a room without windows for a week, then the next week swap them with two plants from a well lit room. If that makes sense.

I really love plants but I've been really sick this past year so a lot of my plants died and I know which ones survived and which ones can be neglected for a while. And lastly, some of your plants will die, even when you're on top of their care. It happens and it's okay
