Introduction
Completing the first year of the RHS Level 2 course in the Principles of Horticulture marked a significant step in my personal and professional development in the field of horticulture. This course provided a comprehensive foundation in plant science, garden maintenance, and sustainable growing practices over the past year.
Course Structure and Content
The course was structured around core units designed to give a solid grounding in horticultural science and practice. Topics included:
Plant Classification and Structure: I learned how plants are scientifically classified using the binomial system, and how this informs identification and care. We explored plant structure in detail, examining the form and function of roots, stems, leaves, flowers, fruits, and seeds. Understanding the role of each structure helped me appreciate how plants grow, reproduce, and interact with their environment.
Hand out from the first lesson 
Information on stems Plant Nutrition and the Root Environment: This section covered the essential nutrients plants need, how they are absorbed, and the importance of soil structure, PH, and organic matter. I learned how to recognize nutrient deficiencies and how to improve soil health through appropriate amendments and management techniques.
Plant Health: Pests, Diseases, and Disorders: This was one of the most practical and eye-opening units. I learned to identify a wide range of common pests (such as Aphids, Vine Weevils, and Red Spider Mites), diseases (including Powdery Mildew, Botrytis, and Rusts), and physiological disorders. We studied both biological and chemical control methods, along with integrated pest management (IPM) strategies. This unit gave me the confidence to diagnose issues in my own garden and at work to make informed decisions about treatment options.
Identifying certain diseases Environmental Factors and Plant Growth: I gained a better understanding of how temperature, light, water, and air circulation impact plant development. The course also emphasized how to modify growing conditions to suit different species, whether through irrigation, shading, or greenhouse use.
Garden Planning and Establishment: This unit focused on designing functional and aesthetically pleasing gardens. It covered site assessment, plant selection, soil preparation, and planting techniques. I enjoyed applying this knowledge in my own space, experimenting with layout and companion planting.
Learning Experience
The delivery of the course was well-organized and engaging. The lessons were clear and supported by information sheets after each lesson, including diagrams, case studies, and quizzes. The tutor was knowledgeable, approachable, and passionate about horticulture, which greatly enriched the learning experience. We even went on a couple of field trips to Angelsey Abbey and to The Botanic Gardens in Cambridge, which I really enjoyed.
One of the highlights was understanding how theoretical concepts translate to real-life gardening practice. I particularly enjoyed learning about the internal structure of leaves and stems, and how processes like photosynthesis and transpiration affect plant health and productivity. These insights have given me a new lens through which I view plants in both professional and personal contexts.
Peer Support and Collaboration
A particularly positive aspect of my experience was being able to share the journey with my work colleague, Abi, who was also completing the course at the same time. We regularly discussed course content, compared notes, and supported each other through challenging topics. Being able to talk through complex material with someone facing the same challenges was incredibly valuable. For example, we often discussed difficult topics like pest identification or plant pathology over coffee breaks, which helped solidify our understanding and made revision more manageable.
I also created a Whatsapp group with our fellow students, which was very valuable when having difficulties understanding a subject, and on the flip side, being able to offer support for others who were in need.
Practical Application
Although Year One primarily focused on theoretical knowledge, I found numerous opportunities to apply what I learned in practical settings. Whether through my day to day work, at home, or even in friends and families gardens, I began to implement sustainable practices, and identify pest and disease problems with greater accuracy. Understanding plant structure also allowed me to make better pruning decisions.
Challenges and Achievements
One of the biggest challenges was adapting to the scientific terminology and level of detail, especially in the plant biology units. However, consistent study and support from my tutor and the ability to discuss difficult concepts with fellow students helped me overcome these hurdles. I was particularly proud of my progress in understanding sustainable practices and how they can be used effectively in different settings.
Conclusion
The RHS Level 2 Year One course has been a great experience. It has strengthened my confidence, equipped me with essential knowledge, and opened up new possibilities for further study or career development in horticulture. I look forward to continuing into year two, building on this strong foundation, and taking my horticultural skills to the next level.
