Shade loving plants such as hostas, heucheras, and astilbes, as well as other moisture loving plants like ferns and begonias, will do well in a concrete planter with a little extra attention paid to their water and sunlight needs.
In cold climates, make sure to bring planters indoors during the winter or sink them into the ground during very cold stretches to protect the roots from frigid temperatures. By picking the right plants, and providing regular care, you can create an attractive and long-lasting display with plants in concrete planters.
Are concrete planters good?
Yes, concrete planters can be a great choice for those looking for an attractive and durable planter for their garden or outdoor space. They offer a classic, timeless look that can enhance any outdoor setting.
Concrete planters are strong and heavy, making them ideal for outdoor environments with high levels of wind, as they will not tip or blow over easily. They are also resistant to both extreme temperatures and moisture, so they will not deteriorate as quickly as other materials like wood would.
Finally, concrete planters are fairly inexpensive, making them a cost-effective option if you are trying to stick to a budget.
Does concrete leach chemicals into soil?
Yes, concrete can leach chemicals into soil, depending on the environmental conditions and the type of concrete used. Concrete is mainly composed of cement, water, amalgam, and various other materials such as sand, gravel and admixtures.
The chemical composition of the concrete itself may contribute to leaching, particularly if the ingredients are acidic or basic. For example, if the concrete is exposed to rain or water, the acidic reaction combined with leaching of the alkaline cement can contaminate the soil beneath the surface.
Additionally, if the concrete contains admixtures such as fly ash or sulfuric acid, these pollutants can leach into the soil as well. If there is an impermeable barrier between the concrete and the soil, the leaching of chemicals into the soil can be minimized.
The leaching can also be reduced by using protective coatings, or waterproofing adhesives, but this does not eliminate it completely. Depending on the environment, the age of the concrete, and the type of concrete used, it is advisable to research the potential of leaching chemicals into the soil before any construction projects are undertaken.
Can concrete planters be left out in winter?
Yes, concrete planters can be left out in winter, provided some basic precautions are taken. In cold climates, you should move them to a sheltered spot to protect them from extreme temperatures, where they won’t be exposed to direct wind, rain, or snow.
Additionally, it is important to keep the planter a few inches off the ground to reduce the risk of frost heave. To provide an extra layer of protection, wrap the planter in a waterproof tarp or blanket.
If you use a tarp, make sure it is tightly secured to keep it from blowing away. Take special care, if your planter has drainage holes, to make sure they are not blocked by the tarp.
Also keep in mind that concrete planters hold heat, so they should be monitored for thawing snow and ice. You should periodically check the planter and make sure water or snow is not pooling inside. This could create cracks or cause your planter to freeze and break apart.
If snow or ice accumulates, use a broom to move it away from the planter to avoid any damage.

If you take these basic precautions, your concrete planter should be able to withstand the winter months without any issues.
How long do concrete planters last?
Concrete planters are incredibly durable and can last for decades if well maintained. They are strong and resistant to wear and tear, as well as harsh weather conditions. However, the longevity of concrete planters depends on a variety of factors including the quality of the material used, the thickness of the planter, the proper use of sealers, and proper maintenance.
To help increase the longevity of a concrete planter, it is important to use a sealer or something to protect the concrete from moisture. Additionally, you may need to occasionally seal any cracks or crevices that may appear over time, as well as inspect the vessel for damage and make any necessary repairs.
With proper maintenance and care, a concrete planter can last for many years and remain looking fresh and new.
Do concrete pots need drainage holes?
Yes, concrete pots generally do need drainage holes because they can easily become waterlogged when watered excessively, resulting in root rot and other negative impacts to the plants. It is important to ensure every pot you use has drainage holes so that excess water is not given the chance to pool in the bottom of the container, which can keep the soil too wet and ultimately suffocate the plant’s roots.
To ensure optimal drainage for your pots, you may want to consider adding a layer of gravel to the base when filling the pot with soil. This layer of gravel helps the water drain out of the pot more quickly, making sure the plant has the optimal drainage roots need to thrive.
Why are my cement pots cracking?
If your cement pots are cracking, it may be due to a few different causes. Most likely, the cracking is from water seeping into the cement material which then expands and contracts due to changes in the heat and cold.
This can cause cracks to form in the cement pot material. Another possible cause of the cracking may be due to the material that was used in the pot not able to support the weight of the soil and plants.
This can often be a problem with thin-walled pots. Additionally, the pot could also take on too much weight when it’s filled with soil, causing it to break under the strain. Finally, if your pot is exposed to large amounts of direct sunlight, it can cause the cement material to weaken and crack overtime.
To prevent your pot from cracking, you should make sure to add a drainage hole to the bottom of the pot to allow excess water to escape and avoid water buildup. Additionally, check the thickness of the pot walls and make sure that it is thick enough to support the weight of the soil and plants.
You should also make sure to not expose your pot to large amounts of direct sunlight to avoid weakening the cement material and causing cracks to form.
How do you waterproof concrete planters?
To properly waterproof concrete planters, you must first clean the planter surface to remove any dirt, debris or efflorescence. Use a vacuum cleaner for this task if necessary. Next, make sure the surface is dry before you begin the waterproofing process.
If there is standing water in the planter, mop it up with a cloth.
Once the planter is dry, apply a liquid latex waterproofing product specifically designed for concrete. This product is typically sold in buckets and applied with a brush, roller or trowel. Start at one end of the planter and work your way to the other end, making sure to evenly spread the waterproofing material across the surface and filling any cracks, holes or indentations.
Wait a minimum of 24 hours before replanting. This will give the latex waterproofer plenty of time to fully dry and set. For added protection, and to ensure the most effective waterproofing, you can apply 2-3 coats of the latex waterproofer, depending on the product and planter size.
Once complete, your concrete planters will be waterproof, so your plants can thrive better for longer.
Will concrete planters crack in the winter?
It is possible for concrete planters to crack in the winter, though the risk of this happening depends on a variety of factors. Cold winter temperatures can cause the water inside concrete planters to freeze, expanding and putting pressure on the planter’s walls.

In addition, if the planter is not properly sealed, moisture can seep in and further expand when frozen. The weight of the planter can also be an issue, as extremely heavy planters may be more prone to cracking.
To reduce this risk, it is important to choose a planter that is high-quality and designed to withstand extremes in temperature and moisture. Additionally, it is recommended to regularly check on your planters during the winter months and to bring them indoors during extreme cold snaps.
Is concrete a good material for planters?
Yes, concrete can be a good material for planters. Concrete is strong, durable, and can withstand harsh weather conditions, making it a great choice for outdoor planters. It can last for decades without needing any major repairs or maintenance.
In addition, it is also generally quite affordable, which makes it ideal for large-scale gardening applications. Concrete also has a natural, earthy aesthetic that can add an interesting touch to outdoor landscaping.
Finally, due to its dense structure, concrete retains moisture well, meaning that your plants will stay hydrated for longer periods of time. Overall, concrete is a great material for planters and can be both cost-effective and aesthetically pleasing.
How do you keep concrete from cracking more?
To keep concrete from cracking more, there are several things you can do to strengthen and protect it. First, be sure to use a high-quality concrete mix with aggregate, and make sure to use reinforcing steel, such as rebars and meshes, to keep the concrete from shifting or weakening as it dries.
Additionally, you should use slow-curing, self-consolidating concrete that has increased flexural strength, allowing it to bend and flex instead of cracking. You can also seal your concrete with a liquid waterproofer or a sealant and make sure to regularly seal it over time to prevent cracking or weakening.
Finally, during curing, keep the concrete moist by misting it with water regularly and use a curing compound to keep it from drying out too quickly.
Why is my quikrete crumbling?
There can be several reasons why your Quikrete is crumbling. Firstly, it is possible that the material was mixed incorrectly, resulting in the dry components not being completely integrated. Secondly, if the quikrete was not mixed with enough water, the binding agents may not have been adequately mixed in to keep the product together which can lead to crumbling.
Additionally, the Quikrete may have been exposed to moisture or high humidity shortly after being applied, which puts too much stress on the curing process. Lastly, it is possible that too much material was applied at one time since Quikrete is a heavier material and may not be able to support its own weight if too thick.
To fix the issue, make sure to follow the instructions on the label when mixing – pay particular attention to the water/quikrete ratio and the timing of the mixing. Ensure proper drainage around the application area, and avoid exposure to moisture for 24 hours after installation.
What kind of concrete do you use to make planters?
The type of concrete used to make planters will depend on the size and shape of the planter, as well as the environment it will be in. For smaller planters, a lightweight concrete mix made with a 1:2 ratio of portland cement and sand is usually best.
This type of concrete is typically easier to work with and can be formed in smaller molds.
For larger projects, especially in exterior applications, a more durable concrete mix is likely necessary. For these projects, a standard mix with a 1:2:4 ratio of portland cement, sand, and gravel is typically used.
This provides good strength and durability for larger planters that may see a lot of wear-and-tear or are exposed to the elements.
No matter what type of concrete is used, you should consider adding admixtures to the mix. Admixtures are specialized chemicals and fibers used to modify the properties of the concrete. These can be used to increase strength, reduce shrinkage, or improve the overall durability of the concrete.
Adding admixtures can help ensure that your planter will stand the test of time.
