Before You Follow a Plant Care Guide: What You Need to Know

I have spent my fair share of time studying plants from many different angles: from plant biology and physiology to plant pathology, soil science, plant nutrition, and pest management. And if there is one thing I have learned, it is this: plant care does not have to be complicated, but it is incredibly contextual.

At their most basic level, plants have relatively simple needs. They need light, water, nutrients, suitable temperatures, and an environment that allows their roots and shoots to function properly. Where things become more complicated is determining how much of each a particular plant needs under a particular set of growing conditions.

So why can two people follow the same care instructions for the same plant and end up with completely different results?

Because a plant care guide cannot account for every environment in which that plant will be grown.

Where you live matters. The direction of your window matters. The season matters. Whether your plant grows in the ground or in a container matters. The size and material of that container matter. Your potting medium, watering habits, temperature, humidity, fertilizer use, and even the amount of light reaching your plant can influence how it grows and how quickly it uses water and nutrients.

This doesn't mean plant care needs to become complicated. It means plant care instructions should be treated as a starting point rather than a rigid set of rules.

For example, you may have heard the common advice to "water less in winter." That can be useful advice, but it doesn't tell you why. Depending on where you live and the conditions inside your home, winter can bring changes in day length, light intensity, temperature, plant growth, and how quickly your potting medium dries. Those changes can affect how quickly a plant uses water.

That's why a watering schedule that works perfectly for one person may not work for another, even when they're growing the exact same species.

My goal with the plant care guides here at Emerald Houseplants is to give you practical recommendations while also explaining the plant science behind them. I don't just want to tell you what to do. I want to help you understand whyyou're doing it.

As this blog grows, we'll explore topics like how plants use light, how water moves through a plant, what roots actually need from their growing environment, how nutrients affect plant growth, why seasons can change plant care, and how the environments where plants evolved can help us understand the plants growing in our homes today.

Because once you understand the why, you don't have to memorize nearly as many rules.

You can learn to understand the plant instead.
