How to Plant in Large Pots: A Gardener’s Guide

How to Plant in Large Pots?

To plant in large pots, start by covering the drainage holes to prevent compost from falling through.

Fill the pot with compost up to 5cm below the rim, considering the viewing angles when positioning plants.

Fill any gaps around the plants with peat-free compost, leaving a slight gap at the top to avoid spilling when watering.

Thoroughly water the plants using a watering can or hose with a fine spray.

Finally, wash off any compost on the leaves with a gentle spray of water.

Key Points:

  • Cover the drainage holes to prevent compost from falling through
  • Fill the pot with compost, leaving a 5cm gap below the rim
  • Fill gaps around plants with peat-free compost, leaving a slight gap at the top
  • Thoroughly water plants using a watering can or hose with a fine spray
  • Wash off any compost on the leaves with a gentle spray of water
  • Consider viewing angles when positioning plants


Did You Know?

1. Did you know that the largest pot ever used for planting was over 10 feet in diameter and weighed more than 15 tons? It was used for a Guinness World Record attempt for the largest flower arrangement display.
2. In ancient Rome, large pots were commonly used for planting small fruit trees, such as lemon and orange trees. These potted trees were often moved indoors during the winter to protect them from cold weather.
3. If you’re looking to plant herbs in large pots, consider adding a layer of gravel at the bottom. This will improve drainage and prevent water from pooling around the roots, keeping them healthy.
4. When planting in large pots, it’s advisable to choose lightweight potting soil that is specially formulated for container gardening. This type of soil is lighter and allows better aeration, promoting healthier plant growth.
5. For an interesting and low-maintenance planting idea, consider creating a “pot within a pot” arrangement. Place a smaller pot inside a larger one, leaving a gap between them. Fill the gap with soil and plant trailing vines or flowers, creating a unique and eye-catching display.

Prevent Compost From Falling Through Large Drainage Holes

When it comes to planting in large pots, one of the first things you need to consider is how to prevent compost from falling through the drainage holes. This can be quite a common problem, but thankfully, there is a simple solution.

Start by covering the large drainage holes with stones or broken terracotta. This will create a barrier that prevents the compost from escaping through the holes. The stones or broken terracotta should be placed at the bottom of the pot before adding the compost. This will ensure that the drainage holes remain unobstructed, allowing excess water to flow out while keeping the compost inside the pot.

  • Use stones or broken terracotta to cover the large drainage holes.
  • Place the stones or broken terracotta at the bottom of the pot before adding the compost.

Properly Fill The Pot With Compost

Once you have taken care of the drainage holes, the next step is to properly fill the pot with compost. You should fill the pot up to the level where the rootballs of the plants will sit, which is usually about 5cm (2in) below the rim of the pot. This will provide enough space for the plants to establish their root systems and ensure that they have enough room to grow. Use a good quality compost that is well-draining and nutrient-rich. It is important to choose a peat-free compost to reduce the impact on the environment. Fill the pot gradually, adding layers of compost and firming it down gently as you go. This will help create a stable foundation for your plants.

  • Choose a peat-free compost
  • Add layers of compost gradually
  • Firm the compost down gently to create a stable foundation for the plants

Consider The Viewing Angles For Plant Positioning

When planting in large pots, it is important to consider the viewing angles of the container. This means taking into account the placement of the pot and the perspective from which it will be viewed.

If the pot will be placed against a wall or a similar structure, taller plants should be positioned at the back. This will create a pleasing visual effect with the taller plants acting as a backdrop for the smaller ones.

On the other hand, if the pot is a free-standing container that will be viewed from all sides, taller plants should be positioned in the center. This will help create a balanced and visually appealing display.

Fill Gaps With Peat-Free Compost

After positioning the plants in the pot, filling any gaps around them with peat-free compost is essential. This not only helps anchor the plants securely but also provides them with the necessary nutrients for growth. To ensure a stable environment for the plants to thrive, gradually fill the gaps and firmly press down the compost to eliminate any air pockets.

Leave A Gap To Avoid Spilling When Watering

To prevent compost from spilling out of the pot during watering, it is crucial to leave a slight gap between the top of the compost and the container. This ensures that the water can be absorbed without causing overflow. Ideally, a gap of approximately 2-3cm (1-1.5in) is sufficient, depending on the pot’s size. This practice not only maintains a neat and tidy look but also promotes appropriate watering techniques.

Thoroughly Watering Plants With Care

Once the planting process is complete, thoroughly water your plants. Use a watering can with a rose attachment or a hose with a fine spray to water the plants slowly and evenly. This will ensure that the water reaches the root system of the plants and promotes healthy growth. Take care not to overwater or create waterlogged conditions, as this can lead to root rot and other issues. After watering, check for any compost that may have gotten on the leaves and gently wash it off with a spray of water. This will help keep the leaves clean and prevent any potential harm to the plants.

Tip: It is important to water your plants properly to promote healthy growth and prevent issues like root rot.

planting in large pots can be a rewarding experience, and by following these guidelines, you can ensure that your plants have the best possible start. By preventing compost from falling through drainage holes, properly filling the pots with compost, considering the viewing angles for plant positioning, filling gaps with peat-free compost, leaving a gap to avoid spilling when watering, and thoroughly watering the plants with care, you can create a beautiful and thriving garden display in your large pots.

Frequently Asked Questions

What can I use to fill the bottom of a large planter?

To fill the bottom of a large planter, you can repurpose various items to promote drainage and prevent soil compaction. One option is to use plastic water and soda bottles filled with sand or gravel. These bottles provide a lightweight and cost-effective solution while allowing for proper water drainage. Another option is to utilize unused nursery pots, which can be stacked upside down to create a base that discourages soil from clogging drainage holes. This not only helps with drainage but also makes it easier to move the planter if needed.

How do you plant in a large container?

To plant in a large container, begin by placing the plant in the center of the container, ensuring it is positioned firmly. Next, press the potting medium securely around the plant’s base, making sure no roots are exposed. Lastly, thoroughly water the plant until drainage occurs from the container’s bottom. This method allows for proper planting and helps establish a healthy environment for the plant’s growth.

Should I put anything in the bottom of my planter?

Yes, it is recommended to place broken pieces of pot at the bottom of your planter for improved drainage. This technique helps prevent compost from escaping through the drainage holes. By breaking unwanted plant pots or chipped crockery into small to medium-sized pieces and adding them as a layer at the bottom, you can ensure better moisture management for your plants.

Do plants grow better in bigger pots?

When it comes to plant growth, bigger pots seem to hold the key to success. Numerous studies have consistently shown that plants thrive better in larger containers. The increased space allows for improved root development, leading to healthier plants, increased leaf area, and greater overall growth. With more room to spread their roots and access essential nutrients, it’s no wonder that plants flourish in larger pots.
