We all have our favorite colors, and likely our favorite colors of containers. 🌈
A question from a client promoted this guide on better and worse colors for your container – from your plant’s point of view.🌿
Why from the plant’s viewpoint you ask? Because you want the most vibrant plants, and as low maintenance a container garden as you can get.
It is easy to choose a color because it is trendy. Yet, because of the nature of “trendy” as transient, when we are buying or painting a container that we will use for several years, we want to move past the simply trendy, to the sustainable.
Worst Colors for Container Your Container Garden
🪴Black
In most cases, the hands-down worst container color is black followed by red.
Here is why.
Black or dark-colored pots can be a double-edged sword. They absorb and retain heat, which might extend the growing season in cooler climates. However, in hot summer months, this extra heat can:
🔥Cause heat stress, leading to wilting and poor plant growth. The black color will heat up faster as it absorbs heat from the sun. In the summertime, it will get so hot that it will burn the soil, and plant roots in from the outer edge inward at least an inch.
🙁 Dry out soil faster, meaning you’ll need to water more frequently.
😢Damage roots if the soil temperature gets too high.
This means you have less growing areas, need to water more often and risk damaging your plants.
🪴Red
Red acts just like black, absorbing too much heat, so everything that applies to black colored containers, applies to red ones.
🪴Other Dark Colors
In general, dark colors are not the best, for the same reason as black container colors.
There are cases, in colder climates, or if you are using a container for cold season growing only, where darker colors could be useful because you want the container to absorb more heat from the lower sunlight.
If your container is in the shade without direct sun, that is the other time you could consider a dark color.
Black and red are still not recommended because even in cooler climates, summer sun can be intense, but you could go with a dark green for example.
🌱 Solution: If you’re in love with black pots, place them in partial shade, mulch the soil surface with light colored straw, or group them with lighter-colored containers to balance out the heat effect.
✅Best Pot Colors for Growing in Containers
🪴White
My go-to container color as it will not absorb the sun’s heat and burn the roots of my plants.
The while color adds a clean look that works with any color house, desk, garage, patio or yard.
🪴Other Light Container Colors
Any other light color container will also protect your soil and plant roots from being overheated.
This is where you can get creative if you would like a container garden that is not all white, or not white at all. You could choose a light grey, green, or even pink or blue. This allows you to have a variety of colors or create a color palate for your container garden.
🪴What if you want a container color you can’t find?
It is possible to paint containers to get the color you want, the only thing you’ll want to check is the type of paint.
Some paint will crack-off or fade. Be sure and check that your paint type is suited for the material of your containers.
🪴Bright Colors
🐝 How Bright Container Colors Can Attract Pollinators (And Which to Avoid!)
Color isn’t just about temperature—it also plays a role in attracting (or repelling) insects! Pollinators like bees and butterflies are drawn to certain colors, while some shades might keep pests away.
🌼 Best Colors to Attract Pollinators:
- Yellow, blue, and purple are favorites for bees and butterflies. These shades help create a buzzing, thriving garden. If you have not had enough pollinators, these good be good options.
- Bright red and orange attract hummingbirds, making them great choices for flowering plants that need bird pollination as long as they are not in full sun.
🚫 Colors That Repel Some Bugs:
- White and very pale colors can deter some insects, as they’re harder for pollinators to see.
- Bright blue or purple might repel certain pests like aphids, making them a strategic choice for planters near vulnerable plants.
💡 Tip: If you want a vibrant, pollinator-friendly garden, mix and match your container colors to create an inviting, dynamic space for beneficial insects!
So as you can see, you’ll need to assess your specific situation to determine what is going to be the best
When choosing a container color, think beyond style—consider how it affects soil temperature, plant health, and garden biodiversity. Whether you want to extend your growing season, conserve water, or invite pollinators, your choice of color can make a surprising difference!
May your container garden be bountiful!
