CONCRETE. Concrete planters are porous so water can evaporate quickly, making them the perfect pot material for cacti and succulents. It’s important that they have drainage holes as well. Concrete planters are durable and great at insulating plants against sudden temperature fluctuations.
One may also ask, can you use cement for plant pots?
Portland cement is considered the best choice for casting and making any type of cement containers. It’s a finely ground cement powder that mixes easily to create a smooth result for your DIY cement pots for plants. Portland cement is the base ingredient for making cement planters.
Then, is cement bad for plants?
Plants are affected by cement and concrete because the limestone (calcium carbonate) it contains can directly affect the pH of soil, increasing its pH to high alkaline levels. This increase in pH reduces the solubility of the minerals in the soil making it less available for plants to absorb.
Why are my cement pots cracking?
The first and most common reason your concrete planter pot cracked is because the mix contained too much water. … The more water that is in the mix, the better the chance that as it evaporates, the concrete will shrink. Concrete by nature will shrink, but the extra water can cause it to shrink too much or quickly.
The best plants for concrete planters are succulents. This is because succulents like soil that is more on the alkaline side and concrete leaches lime which is highly alkaline. However, you can plant any type of plant in a concrete planter, but you may want to soak it in water first.
Combine one part peat moss, one part perlite and one part cement in a plastic container. This is a simple hypertufa recipe. Exact quantities vary among recipes. Add water from a garden hose to the mixture until it’s as thick as cake batter.
Portland cement is another good cement mix for DIY planters. But you must add sand to it, otherwise, it won’t bind. Using a smooth cement mix to achieve smoothness in a planter is important. But also keep in mind that you must also make sure to mix the cement or concrete so that there are no lumps.
Concrete Raises Soil pH
Concrete is alkaline in nature, meaning it has a pH of 7.0 or above. … Concrete, or cement, can affect soil pH when acidic rain or irrigation water falls on a concrete sidewalk, driveway, or building foundation and sheds onto adjacent soil.
We recommend a mixing ratio of 1 to 1(same amounts of cement and sand). 2. For this mixture we went for a semi-textured look so used one part course sand to one part cement. The amount of water is an eyeball thing.
