Gardening Terms For Beginners
Friday, 13 May 2022 | SimplySeed
All professions, sports, crafts and hobbies have their own specific terminology, which to anyone on the outside, might sound a bit like technical jargon or gobble-de-gook. Gardening, or horticulture to give it its specific term, is no different. Below is a list of all the most common gardening terms you might come across, which for a beginner to gardening, could help you hold your own in a gardening conversation with those who are a little more knowledgeable. This does not take into account all the possible local and regional variations and the many thousands of specific plant names and their variations.
Glossary of Gardening Terms.
Acid soil is a type of soil that has a pH level of below 7.0. This type of soil is often found in areas with high levels of rainfall, as the water can leach out essential nutrients and minerals. As a result, acid soil can be very difficult to garden in, as plants may not be able to take up the necessary nutrients for growth.
In addition, acid soil can also be very corrosive, which can damage plant roots and make it difficult for new seedlings to take hold. However, there are some plants that thrive in acid soil, such as rhododendrons and azaleas. For gardeners who wish to grow plants in acid soil, it is important to choose the right plants and to take care not to damage the delicate ecosystem.
Aeration simply means adding oxygen to something.
In terms of gardening, aeration usually refers to loosening up or punching holes in compacted soil so that air, water and nutrients can reach the grassroots more easily. Aeration can be done manually with a garden fork or aerating tool, or mechanically with a gas-powered lawn Aerator.
Aeration is beneficial because it helps reduce water runoff, improves drainage, decreases compaction and thatch build up, and encourages a healthy root system. Aeration is especially important on high-traffic areas of your lawn, such as where kids play or where you typically walk to get to the garden. Aerating once or twice a year will help keep your lawn healthy and looking its best!
When composting, aeration helps to promote the growth of beneficial bacteria and fungi, which play an important role in decomposing organic matter. Aeration also helps to improve drainage and prevent compaction. There are several ways to aerate compost, including turning it with a pitchfork or using an Aerator. Aeration is an important part of the composting process, and it should be done on a regular basis to ensure that compost remains healthy and active.
Aerial roots are a type of root that grows above the ground. These roots are typically found in plants that live in tropical climates, where they help the plant to anchor itself to tree trunks or other structures. Aerial roots can also be found in some houseplants, such as philodendrons and ficus trees. While they are not required for these plants to thrive, aerial roots can help to support the plant and keep it healthy.
In order to encourage aerial roots to grow, gardeners should provide their plants with bright, indirect light and high humidity. With proper care, aerial roots can add an exotic touch to any indoor or outdoor garden.
alkaline soil is a type of soil that has a higher pH than 7. This means that it is more alkaline than neutral. Alkaline soil is often found in arid or desert climates. It can also be found in areas with high limestone or alkaline rock content. The alkalinity of the soil prevents plants from being able to uptake essential nutrients, which can stunt growth or even kill the plant.
In gardening, alkaline soil is often amended with organic matter to help reduce its alkalinity and make it more hospitable for plants. This can be done through the use of compost, mulch, or other amendments. By increasing the organic matter content of alkaline soil, gardeners can make it more fertile and better able to support plant growth.
Annual plants are plants that complete their life cycle in one growing season. This means that they sprout from seed, flower, and produce new seeds all within the span of a few months. annual plants are often used in gardens because they provide a burst of color and can be easily replaced the following year.
Many annual plants are annual flowers, such as petunias and impatiens. However, some vegetables, such as beans and squash, are also annuals. No matter what type of annual plant you are growing, it is important to keep an eye on the blooming schedule so that you can replant on time. With a little planning, annual plants can add beauty and variety to your garden for years to come.
Plants that are typically supplied during the dormant season from a nursery or garden centre, and which are not in a pot.
A flower, which has two distinctly different colours.
A plant that takes two years to reach maturity, after which it will flower and die.
Biological Pest Control
A natural method of controlling garden pests by introducing parasites. “Nemasys” is a typical example.
In gardening, bolting refers to the rapid and premature flowering of a plant. This usually occurs when the plant is exposed to extended periods of warm weather or stress. Bolting can be disastrous for gardeners because it significantly reduces the yield of fruits and vegetables. In some cases, bolting also causes the produce to be smaller and of lower quality. To avoid bolting, gardeners should carefully monitor the weather forecast and take steps to protect their plants from excessive heat or stress. Additionally, they can choose varieties of fruits and vegetables that are less likely to bolt. With a little care and attention, bolting can be prevented and a bountiful harvest can be enjoyed.
A bulbous, underground fleshy storage system, from which a plant will obtain its nutrients, grow and flower. A daffodil is a typical example.
