Creating a container herb garden is a very flexible way to grow fresh herbs in the home garden. Most herbs are well suited to growing in containers.
Growing herbs in pots also allows you to move them around as needed to new areas of your garden or bring them closer to your kitchen. You can change the arrangement according to the season and create focal points in your garden depending on which herbs are blooming.
Always review the growing requirements of the specific herb you decide to include in your potted herb garden before selecting pot.
Here are some great tips to choosing the right herb pot for your plants.
1. Select Herb Pots that have Good Drainage Holes.
Outdoor pots should good sized drainage holes to allow for easy draining. When it rains, the water will need to be able to drain thoroughly or your herbs will be swimming. Most herbs do not appreciate having “wet feet”.
2. Choose the Right Size Pot for your Herb Plants.
The size of the pot you choose will contribute to the overall size of the herb plant. If you want your potted herbs to reach their full potential, select a container for your herbs that will accommodate the mature size of the plants. See the chart below to check the mature size of the most common culinary herbs. Here are a few basic tips to keep in mind when planning your container herb garden.
- Herb Pots should be a minimum of 6 inches in diameter. Only the dwarf or creeping varieties of culinary herbs should be placed in a small pot, such as thyme or spicy globe basil.
- Herbs that are heavy spreaders can be contained by the size of the pot. A mint will fill either a 6 inch or 20 inch pot in time. You can control your potted herbs size by limiting the size of the pot.
- Some herbs do better in deeper pots, such as Parsley & Basil. Parsley has a long taproot & basil has an extensive root system. When selecting a pot for parsley or basil, make sure the pot is at least 18 inches deep.
- When you are purchase herb plants in nursery pots from a garden center, you will want to re-pot them into new pots which are at least double the size of the nursery container.
3. Choose the Right Materials For Your Herb Pots.
Herb Pots are made from several different types of materials. Choose the types of material used in your container herb garden based on the following factors:
- The durability for holding up to the outdoor elements.
- The weight of the pot and your ability to move it once it is filled with soil and your plants.
- The moisture retaining ability of the material.
Here are some common materials used for herb containers and the pros & cons of each.
Clay or Terracotta Pots. Clay pots are an affordable pot material which looks nice in many landscapes. They are also not terribly heavy. However, you may need to bring clay pots inside over the winter since they may crack when exposed to fluctuating outdoor temperatures. Their porous nature may also require more frequent watering since they tend to dry out quicker.
Cement or Stone Pots. Stone pots can be absolutely beautiful and there are many pretty treatments, such as glazing or hand painted pots. However, stone pots will be very heavy. These are good choices when the pot will become part of the landscape like large stone pots on either side of an entry way. But they will be very hard to lift once filled with soil and herbs. Don’t choose this type of herb pot when you know you will want to move them around your potted herb garden.
Plastic, Fiberglass and Resin Pots. These can be an attractive solution while remaining affordable. These are also much lighter & easier to move, so are good choices when you need to re-position them in your container herb garden. The downside is they are not as durable and the color may fade or chip over time.
4. Design a Container Herb Garden with Shapes, Sizes and Colors.
Give some thought to the overall impact you want to create with your container herb garden and its role in your landscape. Do you want to make a statement or do you prefer a more natural look? Ask yourself these questions when deciding on your choice of herb containers.
• How will you use color?
Do you want the pots to blend in with the rest of your garden? Then choose neutral colors and let the herbs be the focal point instead of the containers.
Do you have a formal landscape? Having too many colors could be distracting. In this case, you can stick to one or two complimentary colors.
Do you want a playful, eclectic garden? Then choosing a few bright colored pots may be just right.
• What Sizes do you need?
Always choose larger pots over smaller pots when given the choice. Fifteen small pots will end up looking very messy. You may consider a few large planters where you can combine several herbs that have similar growing requirements. Then place a few medium or small pots in front to create a small grouping. Spend some time in the garden center or planning it out on paper first, so you can consider the overall effect of your container herb garden before you make the purchase.
• What shapes do you prefer?
Herb pots come in a variety of shapes and sizes. We typically think of rounded pots, but square pots can fit into some areas much easier such as on either side of a doorway. A long rectangle trough or window box may look nice framing the sides of your patio or deck.
Designing your potted herb garden is a fun exercise and when done with some planning can be a beautiful addition to your home & garden’s appeal.
