What is The Best Cactus For Outdoor Pots?

When it comes to choosing the best cactus for outdoor pots, there are a few things you need to take into account.

The first is the climate in your area. If you live in an area with very hot summers and mild winters, then you’ll want to choose a cactus that can handle both extremes.

The second thing to consider is the type of pot you’ll be using. Cacti come in all shapes and sizes, so it’s important to pick one that will fit well in the pot you have. Otherwise, your cactus may not get the proper drainage and could suffer from root rot.

Finally, take into account the amount of sun your outdoor area gets. Some cacti do better in full sun, while others prefer partial shade.

If you’re not sure which type of cactus would do best in your outdoor space, ask a nursery or garden center employee for help.

Once you’ve taken all of these factors into consideration, you should have no trouble choosing the best cactus for outdoor pots.

Just remember to give your cactus plenty of room to grow and to water it regularly so that it stays healthy and happy.

Can Potted Cactus Stay Outside In Winter?

Cactus in Winter

As winter approaches, you may be wondering if your potted cactus can stay outside. After all, cacti are desert plants and thrive in hot, dry conditions.

So, can potted cactus stay outside in winter? The answer is yes, but there are a few things to keep in mind. First, most cacti are not frost-tolerant and will need to be brought inside or protected from the cold if temperatures dip below freezing.

Second, even if your cactus is frost-tolerant, it may still suffer from the cold, windy weather often associated with winter.

Here are a few tips for keeping your potted cactus happy and healthy during the winter months:

Bring it inside: If the temperature in your area is forecast to dip below freezing, it’s best to bring your cactus inside.

Place it in a sunny spot, such as near a south-facing window, and water it as needed. However, be sure not to overwater it, cacti prefer to be on the dry side.

Protect it from the wind: Wind can damage cacti, causing them to lose water and become stressed. If you can’t bring your cactus inside, place it in a protected spot, such as against a south-facing wall or under a tree.

Water it less: Cacti don’t need much water to survive, so cut back on watering during the winter months. Once every two weeks should suffice.

Fertilize it sparingly: If you fertilize your cactus, do so sparingly during the winter months. Too much fertilizer can burn the roots and damage the plant.

By following these tips, you can keep your potted cactus healthy and happy all winter long.

Do You Water Cactus From The Top Or Bottom?

When it comes to watering cacti, there is no one-size-fits-all answer. The best method for watering your cactus will depend on the type of cactus you have, the size and shape of your pot, and the climate you live in.

If you’re not sure how often to water your cactus, start by checking the soil every few days. If the top inch or so of soil is dry, it’s time to water.

When watering your cactus, be sure to use room-temperature water. Cold water can shock your plant and cause root rot.

To water a cactus from the top, simply pour water onto the soil around the base of the plant. Allow the water to seep in and then drain off any excess.

To water a cactus from the bottom, place the pot in a sink or basin filled with room-temperature water. Allow the plant to soak for 10-15 minutes, then remove it from the water and allow any excess to drain off.

Whichever method you choose, be sure not to over-water your cactus. Too much water can lead to root rot, which can be deadly to your plant.

If you’re unsure whether or not you’re watering your cactus too much, it’s best to err on the side of caution and water less often.


Overall, cactus are a great option for outdoor pots. They are low maintenance, drought tolerant, and can add a unique touch to your garden or patio.

If you live in an area with hot summers, be sure to choose a cactus that is heat tolerant. With proper care, your cactus will thrive for years to come.
