Redwood is strong and easy to work with, making it an ideal choice for those with limited carpentry experience. Both are affordable, so you can build a beautiful planter box without breaking the bank.

What do you put at the bottom of a planter box?

When it comes to the bottom of a planter box, natural materials are the way to go. Pine cones, wood chips, leaves, and sticks can all provide drainage and aeration while also helping to keep the soil in the box. However, these materials will eventually break down over time, so they’re best suited for seasonal planters who repot regularly. If a longer-term solution is desired, gravel, rocks, and other man-made materials can be used that won’t decompose and will last for years. Additionally, potting soil can be used at the bottom of the planter box to help hold moisture, add nutrients, and improve drainage.

In order to ensure proper drainage and aeration for your planter box, below is a list of natural and man-made materials that can be used for the bottom:

  • Pine cones
  • Wood chips
  • Leaves
  • Sticks
  • Gravel
  • Rocks
  • Potting soil

Do you need to line the inside of a wooden planter?

It is important to consider the positioning of your wooden planter before deciding whether to line the inside of it or not. For example, if the planter is being placed in a spot where it will receive full sun, then it is beneficial to line the inside with pieces of old compost bag. This will help to keep the compost moist and reduce the need for regular watering. Additionally, it is essential to ensure that the planter has drainage holes, so that the plants do not become waterlogged. As such, it is important to consider the positioning of the planter before deciding if it requires lining.

Besides considering the positioning of your wooden planter, there are several other factors to consider before deciding to line the inside. For example, the type of plants you are planting and the amount of soil in the planter can both influence the decision. If planting shallow-rooted plants with a small amount of soil, then it is likely that lining the planter is not necessary. However, if planting deep-rooted plants with a large amount of soil, then it is recommended to line the inside of the planter to help retain moisture. Additionally, lining can help to reduce the risk of root rot and the spread of diseases. Therefore, it is important to carefully consider all factors before deciding whether to line the inside of your wooden planter.

Do planter boxes need drainage?

Planter boxes are essential for healthy and thriving plants, and proper drainage is key for this to occur. It is highly recommended that planter boxes have drain holes to ensure the roots get adequate air. Stagnant water can cause root rot, which can be fatal for plants, so it is important to ensure that water can easily drain away. Drain holes should be placed at the bottom of the planter box, however, consider the size of the hole and the type of soil you are using to ensure the soil does not wash away too quickly. Furthermore, the addition of a drainage layer such as gravel can help to ensure water is draining away efficiently. With these considerations in mind, your plants will be more likely to thrive and flourish in a properly drained planter box.

Building a planter box is a great way to add a unique touch to your outdoor space. With the right materials and tools, you can create a stunning DIY planter box that will last for years to come. Whether you choose to use wood, clay pots, straw bales, bamboo, or deck railings, the possibilities are endless.
