Home Horticulture is a trial event run in Division B and Division C for the 2021 season. It is an event with both lab and exam portions that test knowledge about the practice of garden cultivation and management from home. Horticulture has also been a trial event in several states, taking the form of Horticulture Science (as run in Wisconsin) or simply Horticulture. Participants may bring one three-ring binder of any size, two calculators of any kind, and a soil test kit for the lab portion of the event. For all calculations, English units will be used as they are what is most commonly used in horticultural practices.

Plant propagation is the process of growing more of a plant from plant parts such as seeds and cuttings. Growing plants in this way is often used for purposes such as creating aesthetically pleasing plant decorations and food cultivation.
Soil tests can show the health and fertility of a plot of soil based upon the nutrients present. The wrong pH levels, nitrogen, phosphorus, or potassium content of the soil can often make it harder for plants to thrive. Some plants also grow better in different soil conditions, meaning that after doing a soil test one can make adjustments to the soil properties so that the plant that is being cultivated can grow in its best soil conditions. For most plants (there are some exceptions), the pH of soil should be around 6.0 to 7.0 for them to thrive. If the soil is too acidic (lower on the pH scale), it is more prone to minerals that can be toxic when too much is absorbed, such as manganese. If the soil is too basic/alkaline (higher on the pH scale), plants can't take in the nutrients they need.
