RHS Level 3 Certificate in the Principles of Plant Growth, Garden Planning and Applied Propagation

Unit List

1. Horticultural Heritage

This unit provides learners with the opportunity to investigate the key periods of history with relation to garden design including the principle design features for each period and an awareness of the key influences on the development of gardens including politics, exploration and trade, colonialisation and development of empire, and the assimilation of gardening styles from different cultures.

Learners have opportunities to explore the value of horticultural heritage to society, including the economic benefits, the role of heritage gardens and designed landscapes in conservation, along with the models and techniques that are used to evaluate these concepts.

Learners will also be aware of the impact of horticultural heritage on the management of gardens and designed landscapes informs many of the decisions required in the care of these important spaces. This includes aspects such as statements of significance, prioritisation of works and spirit of place.

2. Plant knowledge

In this unit, learners will explore plant exploration and collecting in both historic gardens and landscapes, and current practice. They will develop skills in research to inform plant husbandry including assessing the reliability of information sources, along with a knowledge of international standards of plant nomenclature.

This unit covers areas of research that include; origin and natural habitat, folklore and use in medicine, biodiversity ratings and conservation status. From this research, learners will be able to apply this information to the selection of species, the management of living collections and horticultural interpretation.

3. Plant selection and cultivation

In this unit learners will explore the function and role that plants play within a garden, understanding how the specification of plant material is critical to the ultimate quality of plantings. Learners will understand how to use technical language and apply a range of criteria to inform the specification of plants for planting. Learners will explore how plant-based design principles support the selection of combinations of plants to create gardens and designed landscapes.

Learners will also understand how to select plant species to fulfil a function within a garden or designed landscape. This includes the specification of plant material and the combination of plants to create a garden.

4. Managing plant propagation

In this unit, learners will develop an understanding of the management of plant propagation operations, including propagation facilities, planning processes, propagation techniques, and the development of propagation protocols. Learners will explore the effective use of propagation facilities and examine how specialist techniques, research, and development can be applied to maximise the value of investment in plants for planting schemes, heritage landscapes, plant collections, and commercial stock production.

5. Garden styles and Specialist Areas

In this unit, learners will understand how to determine and work with a number of different design styles. They will explore how garden styles are created in part by the selection and style of plantings and how the gardens created can benefit the wildlife and biodiversity, along with the mental health and wellbeing of garden visitors.

Learners will also understand how hard landscaping materials, including paths, benches and plant supports contribute to the design style and planting to create ambience. Learners will explore how the use of trees influence garden style whilst providing a range of functions for both the environment and visitors.

6 Productive growing

In this unit, learners will explore the role of productive growing within a garden setting which involves the cultivation of fruit, vegetables and flowers for cutting. Learners will understand how productive growing involves careful planning and scheduling of crops for continuity of supply. It also involves the selection and implementation of cropping systems and approaches.

Learners will also understand how successful productive growing includes a number of key elements, for example, optimising soil fertility, the management of weeds and other unwanted plants, along with the application of best practice and sustainability. They will consider how to use the latest findings from horticultural research and development. This research informs the selection of crops, cultivars, and husbandry decisions.

7. Gardens management

In this unit, learners will explore the ways in which gardens are maintained and managed. They will understand how to ensure that maintenance is carried out in an appropriate and sustainable manner. This process includes the recruitment, induction and training of staff, the development of maintenance schedules and the management of health and safety.

They will also understand how to devise, implement and manage projects within gardens.

Learners will understand how to set standards, and use IT to develop and implement maintenance schedules and garden management plans.

8. Gardens, people and spaces

In this unit, learners will explore the role of gardens as visitor attractions. They will understand how gardens are judged on the quality of their pre-arrival information, the arrival experience, the experience of wandering through plantings and garden areas, the customer care offered by team members along with the quality, range and diversity of events and exhibitions.

Learners will understand that horticulturists who manage gardens will often work on a variety of projects to engage their communities within the garden under their care, including involving communities adopting areas of gardens, volunteering and the development of school gardens.

Learners will also explore how gardens and gardening impact on wellbeing and the role of gardens as places of nature-based therapy.

Learners will understand the importance of using feedback from a range of stakeholders to improve standards.
