How To Build A Planter Out Of Concrete Blocks

Concrete blocks are not just industrial building materials. These sturdy blocks can also make great planters. By mixing concrete and waterproofing it with a sealant, you can fashion a planter that is both virtually indestructible and very attractive. You can even sink it into the ground if you like, or place it on a patio or deck. It’s great for growing fruit trees or other large vegetable plants where you want a constant supply of food throughout the seasons. A concrete block planter is a great way to beautify your garden or yard. With their low cost and ease of assembly, concrete blocks can quickly turn any space into a garden filled with plants and flowers. With some basic tools and materials, you can build a concrete block planter that’s designed to withstand the elements and last for years.

Cinder blocks are commonly used in buildings and outdoor construction, but they’ve got a lot of other practical uses too. For example, with just a little bit of know-how and some elbow grease, you can make your own cinder block planter. A few cinder blocks can be transformed into a unique and stylish container for plants to liven up your porch or yard. Here’s an easy step-by-step guide to building your own cinder block planter.

Materials needed

You will need the following materials:

  • Cinder blocks
  • Planting soil or potting mix
  • Plants (ideally small succulents)
  • Watering can or hose with a spray nozzle, and a trowel for planting. You may also want to have some paint and paintbrushes around to make your planter look more colorful. If you’re painting on concrete blocks, it’s important that they are dry before you apply any kind of sealer or paint; otherwise, water can seep into the cracks and cause them to crack further.

Preparing the cinder blocks

To prepare the cinder blocks, you will need to wash them. First, use soapy water and a sponge to clean any dirt or debris from the cinder blocks. Next, rinse them thoroughly with clean water and allow them to dry completely before proceeding with additional steps.

Preparing the base

Before you start building your planter out of concrete blocks, you must prepare its base. The best way to do this is to lay down some paving slabs or bricks and make sure it’s level. It’s also important that the base is large enough for your chosen planter and strong enough to hold it. If you’re using a wooden base (which is ideal), make sure that it’s sealed with a waterproof sealant so no water will get into the wood and rot it over time.

Also, consider the size of your plants when choosing what type of planter to build. Taller plants will need taller containers because they won’t fit easily into smaller ones; likewise, shorter plants can be placed in smaller containers as well as larger ones since they don’t need as much soil depth as tall ones do.

Adding the plants

If you’ve followed the steps above, your planter is almost complete! Now it’s time to add some plants and make it look even better.

  • Planting: First thing’s first, you need to find out what kind of plants will work best in your planter and space. This depends on how much sun or shade they need, as well as their height and width (some get quite big). Keep in mind that plants may also have very different water needs depending on whether they’re indoor or outdoor varieties—you’ll want something that won’t dry out too quickly if you have limited access to water sources at home.
  • Watering: You’ll likely be watering these regularly throughout the week using an automatic watering system like a drip irrigation system installed under each plant; however, check your local garden center for what works best with your specific type of planter before setting one up yourself so that everything stays nice and moist throughout the year! Oftentimes this involves installing a few small holes near the bottom where moisture can seep through into each pot without getting stuck inside there; just make sure not too much water gets inside because then it could cause mold growth.

Extra tips and ideas

  • Make sure to use a mortar mix made for concrete blocks, and not just regular old concrete by itself.
  • If you’re going to be using any type of decorative accent with your planter, make sure it’s the same color as your mortar so it sticks out.
  • If you’re going to be planting flowers in your planter (like those pictured), make sure they match the color of whatever mortar you choose to use! This is particularly important if you want them to stand out against the background properly.

It’s also important that your mortar be rated for both indoor and outdoor use in order to protect against weathering over time – which can happen even if they’re stored indoors or under shelter during winter months.

building a planter with cinder blocks is relatively easy

Building a planter with cinder blocks is relatively easy. You will want to prep the cinder blocks first, so they are ready to be put into place when you start laying out your planter. The base of your planter should be level and sturdy enough to support all of the weight from your plants and soil.

Once you have prepared both the cinder blocks and base, it’s time for planting! Cinder blocks come in different shapes, sizes and colors—so make sure to choose ones that match your home décor if possible. You can also paint them if need be; however this process can get messy because paint will drip down between gaps in between each block.

When choosing flowers or other plants for this project make sure they won’t grow too tall as there isn’t much clearance between each layer of concrete blocks once everything is laid out flat against each other without any additional height added on top via pots or containers filled with soil mixture that surrounds each individual plant growing inside them.

Final words

While building a planter with cinder blocks may seem like an easy task, there are quite a few factors that need to be taken into consideration before you get started. However, once you have all of the necessary materials and tools, it is relatively easy to complete this project. You will need to prepare your work area by measuring out exactly where each block will go and then building the base. After that, it is just a matter of filling in the gaps with dirt and plants.
