Water

Of course, every plant grown indoors will have differing requirements in terms of watering.

However, one of the biggest common problems for indoor gardens is overwatering.

Many indoor plants die as a result of root rot.

Always research what the plant species you are growing needs.

Watering your plants with room temperature water is also a good idea.

Cold tap water can shock your plants.

Fertilizer

Ensuring your indoor garden plants receive enough nutrients is important for long-term success.

Although some potting soils have nutrient enhancements, the plants will use them up after a couple of months.

Slow-release fertilizers are popular as they can last several months before another program is required.

The ideal humidity level for many indoor plants ranges from around 40 to 60 percent humidity.

you’re free to also use indoor greenhouses or terrariums.

check that the pot is big enough for future growth.
