Growing Herbs in Containers
As a horticulturist, we have favorite endeavors such as growing plants especially herbs in colorful containers of all colors and shapes. Herbs make an excellent choice to decorate a sunny patio, deck, or balcony, and the flowers that are produced on herbs will provide twice the amount of fun to your growing area. The seeds and flowers will provide additional ingredients to recipes. Processing the seeds produced by herbs make additional ingredients to add to recipes. For example, when Cilantro goes to seed the seeds are called Coriander when crushed; and when Dill goes to seed the processed seeds are called Dill Weed. Most flowers produced by herbs are edible and are used in salads, garnishes, and cooking or can be used in dried floral arrangements. For example, add Mexican Marigold Mint flowers to salads and Lavender flowers can be dried and used in floral arrangements. Plants that are classified as Herbs are very diverse and have multiple uses around the home. Here are a few tips to get you started with growing Herbs in containers.
Deciding a Location: Choose an area that gets 5 - 6 hours of full sun; and if, you have an area that receives more than 6 hours of sunlight that’s all right, too.
Deciding a Container(s): Choose a container that is 6 inches or larger, some of the perennials can be grown in larger containers are Lemon Grass and Sweet Bay.
Deciding a Soil: There are several potting soils on the market and choosing one is a matter of your gardening preferences. Some of the choices are inorganic verses organic, with moisture control or without moisture control, with timed-release fertilizer or without fertilizer. Some potting soils are especially formulated for herbs and vegetables, which would make an excellent choice to use.
Deciding a Fertilizer: There are several fertilizers on the market and choosing one is a matter of your gardening preferences. Some of the choices are water soluble, granular, time-release, slow-release, organic, or inorganic. Choose a fertilizer that is formulated for herbs or vegetable plants. Most gardeners agree in using a combination of time-release fertilizer and a weekly or bi-weekly feeding of a water-soluble fertilizer of your choice.
Choosing an Insecticide: When growing herbs in containers, you may want to consider an IPM (Integrated Pest Management) approach method to control insects on your herbs and using an IPM approach involves a two-step method approach, inspection of the herbs, and what type of control method you are going to use. The first part would be scouting, observing, and inspecting your prized Herbs for insects or chew marks on the leaves. Constantly scouting and observing daily for any insect or worm that would start eating your prize Herbs, and when one was seen, you can simply dispose of the insect. However, sometimes these critters multiply overnight and when this happens it is advisable to spray with a Safer Soap or a Horticultural oil. Using Safer Soaps or Horticultural Oils on all the Herbs mentioned is an organic and an IPM approach to growing Herbs.
Watering: Of all the ingredients that have been mentioned for Herb Container gardening success, water, is the most important to a successful Herb Container garden. The soil for your Herbs will need to be consistently moist at all times, but not soggy wet and the water source should be city water or treated water. This is one of the reasons of last’s years Salmonella outbreaks on produce; the Herbs that were recalled received Salmonella during either the growing process or the production process. Due to all the current recalls of produce, more gardeners are starting to grow their own Herbs this year versus last year due to the recent outbreaks in store-bought produce. Just another reason to start growing your own Herbs, you supply the water, you supply the insecticide, and you know exactly what ingredients went into your Herbs. For states that are currently under water restrictions, you can water your food crops, personal food garden, or personal Herb garden without penalty. Wash all Herbs before eating or cooking, whether Home Grown or Store Bought.
Put on your gardening gloves and reap the rewards and benefits of an Herb Container garden. You will have tastier Herbs than store bought that you harvest on your own. As an Herb Container gardener you know the ingredients, and there is nothing more rewarding than tasting the “Herbs” of your labors.
