Heat: A form of energy associated with the movement of atoms and molecules in a substance, often experienced as a sensation of warmth.
Heat plays a crucial role in many aspects of plant growth and development in gardening. It influences seed germination, photosynthesis, transpiration, and overall plant metabolism. Different plants have different heat requirements, with some thriving in warm climates and others prefer cooler conditions.
Understanding heat is essential for home gardeners to choose the right plants for their climate and provide them with optimal growing conditions. Factors like air temperature, soil temperature, and sunlight intensity all contribute to the heat environment in your garden. Monitoring these factors and taking steps to moderate heat stress, such as providing shade or using mulch, can help your plants thrive, especially during hot summer months. Heat can also affect the timing of planting and harvesting, as well as the prevalence of certain pests and diseases.
