Choose plants based on light in your space
Are the plants you love the ones you can have? The available light in your space will help you decide. Check the direction your windows are facing; south-facing windows give bright light, east/west-facing windows give moderate light and north-facing windows give low light. Most houseplants prefer bright, indirect sunlight.
If the sun is intense through your windows, add a lovely sheer curtain to diffuse the light. Cacti and some succulents like aloe can of course handle brighter, direct sunlight. You don’t want to overexpose or underexpose any plant. They need the right amount of light to live.
Raise the humidity levels
Staying true to your plants natural environment will help your plant thrive indoors. Most tropical plants, ferns and orchids prefer high humidity and bright to moderate, indirect light. Mist these plants in between waterings with filtered water. During the dry months of winter, grouping similar plants together helps to create a more humid microclimate. A humidifier can help too and it’s great for humans. On the other hand, most desert dwellers, like cacti, prefer dry air and bright, direct light with no shade at all. They definitely don’t need to be misted and don’t care for humidity all that much.
A note on stability
Keep your plant’s home environment as stable as possible. Extreme changes can stress plants out. Keep the temperature between 65 and 75 degrees F. Avoid placing your plants near radiators, A/C units and forced-air vents, which can create hot or cold drafts.
