How to Plant in Planter Boxes: Tips and Tricks

Welcome avid gardeners! If you are looking for a way to enjoy your green thumb even if you lack a sprawling lawn, planter boxes are a fantastic option. Not only do they save space, but they also allow you to create a visually appealing garden right on your patio. In this article, we will guide you through the necessary steps to turn your planter box dreams into a reality.


Step 1: Pick Your Planter Box

Your planter box choice will depend on personal preference, but you should keep some practical factors in mind. Consider how much space you have and the size of the plants you wish to grow. Also, decide on the kind of material you would like; plastic or terra cotta, or even repurposed materials such as crates work well.

Step 2: Drainage is Key

Drainage holes in your planter box can prevent water from pooling at the bottom, which causes root rot. Ensure your box has drainage holes by adding them to the bottom or sides of the box.

Step 3: Add a Layer of Gravel

The perfect foundation for a successful garden is a layer of gravel at the bottom of your planter box. This provides excellent drainage for excess water.

Step 4: Add Potting Soil

Fill your planter box with high-quality potting soil. Make sure it’s not too compact, allowing the roots to spread. Leave around one inch of space at the top to allow for watering.

Step 5: Choose Your Plants Carefully

When selecting plants, check the label to ensure they are suitable for your region and the size of your planter box. Also, be sure that the plants selected can grow to fruition in a planter box.

Step 6: Water Your Plants

After planting, make sure to water your plants adequately. Keep an eye on the soil’s dryness level and make sure to water the plants just enough to keep them healthy.

Step 7: Provide the Right Amount of Sunlight

Plants require sunlight to thrive. Determine if your plants are suited to sun or shade and make sure to place them accordingly. Check the label and research if necessary.

Step 8: Weeding and Mulching

Pull any weeds that appear in your planter box as soon as possible to prevent competition for resources. Mulching can decrease weed growth and retain moisture in the soil. Add mulch to the top layer of soil around your plants.

Step 9: Fertilization is Important

Plants can easily become nutrient depleted in a planter box. Add nutrient-rich fertilizer or compost to keep your plants healthy. Check the plant and its requirements to pick the appropriate fertilizer.

Step 10: Control Pest Problems

Check plants for pests, prevention is key. Many organic solutions are purchasable at garden stores or can easily be made with common household ingredients.

Step 11: Harvest Your Produce

Step 12: Refresh Your Soil

It’s essential to replace some of the soil in your planter box from time to time. As it’s used up by plants, beneficial nutrient-rich soil can diminish. When planting your next cycle of vegetables, refresh with the appropriate amount of soil.

Step 13: Adapt to the seasons

The seasons bring about different growing cycles that play an essential part in the success of your planter box. Research when your plants grow best to optimize your planter box for seasonal growth.

Step 14: Look for Compatible Plants

Companion planting can help plants growing together thrive by providing beneficial nutrients to others. Research and look for plants that harmonize together and plant them side-by-side.

Step 15: Enjoy The Fruits Of Your Labor

A well-cared-for and attended planter box garden can be incredibly fruitful, producing an abundance of healthy, home-grown crops. Enjoy the satisfaction of enjoying your produce, and share with friends and family.

Strengths and Weaknesses of Planting in Planter Boxes


1. Suitable for small spaces: Planter boxes are ideal for those who want to grow plants but have limited space. They can be used on balconies, patios, and even inside homes to bring a touch of nature indoors.

2. Easy to move around: Planter boxes are portable and can be moved as needed. This is particularly useful for those who like to rearrange their outdoor space frequently.

3. Better soil control: The soil in planter boxes can be precisely controlled, making it easier to create the ideal growing conditions for plants. This is especially helpful for crops that require specific pH levels or soil types.

4. Improved drainage: Proper drainage is essential for plant growth, and planter boxes usually have drainage holes to prevent water from accumulating at the root level.

5. Aesthetically pleasing: Planter boxes come in a variety of styles and colors, allowing you to match them with your outdoor decor. They can also be used to create beautiful container gardens.

4. Cost: depending on the construction material and size, planter boxes can be more expensive than traditional gardens, making it difficult to create a large garden area.

5. Dependence on fertilizers: Because the soil in planter boxes cannot be naturally revitalized, you may need to resort to fertilizers and nutrients to keep the soil healthy.
