Do you have a houseplant that seems unhappy? Trust your gut. If the plant looks like it’s struggling, it probably is. But don’t worry! There are only two causes for most indoor plant problems: light or water (or both). And I’m going to let you in on the top-secret two-step method for houseplant happiness.
All too often, houseplants don’t get enough light, or they drown in too much water, or they dry out because we forget to water them. It happens. It doesn’t make you a bad person.

Here’s the top-secret two-step:
1. Look at your plant. Does it look happy? Does it look strong and proud or weepy or saggy or sparse or shriveled? What color are the leaves? Look at the soil. Is the surface smooth, cracked, covered in white crumbs or green goop? Touch the soil, heck stick your finger in the soil at least to your first knuckle. Is the soil dry and brittle? Dense and soggy? Gather up your data and visit the links above.
2. Do something different immediately, but not too different. Yes, your struggling plant needs a change, but too much change at once could kill it. Change your watering frequency or move the plant to a new spot or repot the plant. Doing all three at once could be too much stress for an already struggling plant.
My houseplant care regimen looks like this:
1. Bring plants indoors when nighttime temps get to 50 degrees and below. Place them near windows that best approximate their light needs. Some of the plants overwinter under grow bulbs.
2. Water the plants every week unless they don’t need it (finger into the soil to test). Take the plants to the sink or the shower, water thoroughly, let them drain, take them back. I often rotate the plants so a different side faces the window every week, to keep the growth more consistent. I rarely fertilize houseplants in the winter.
3. Take most of the houseplants outdoors when nighttime temps get to 50 degrees and above. Keep them in the shade (I like to hang them in trees) or with at most a few hours of morning sunlight.
4. Water when they need it, paying attention to how often it rains or just use the aforementioned finger test. If it’s hot and it doesn’t rain they need water multiple times per week.
5. Fertilize once per month. I’m a big fan of Planet Natural‘s organic fertilizers.
All else equal:
Plants in bigger pots are more resilient than those in smaller pots.
Plants in pots with drainage holes are healthier than those in pots without holes.
Squishy-leaved plants (succulents) need less water than other plants.
Flowering plants need more water than other plants.
