An overview of what horticulture is, its importance, branches of horticulture, and its impact on the environment and economy.
Introduction to Horticulture
Key concepts, main branches, and practical applications
| Aspect | Description |
|---|---|
| Definition | The science and art of growing, cultivating, and managing plants for food, medicine, aesthetics, and environmental benefit. |
| Scope | Includes fruits, vegetables, ornamental plants, herbs, nuts, and turf. |
| Goal | Improve plant quality, yield, and sustainability while meeting human needs. |
| Relation to Agriculture | Horticulture is a subset of agriculture focused on high‑value, often per‑plant crops rather than bulk field crops (e.g., wheat, corn). |
| Sub‑discipline | Primary Focus | Typical Crops/Plants |
|---|---|---|
| Pomology | Fruit production and post‑harvest handling | Apples, mangoes, berries |
| Olericulture | Vegetable cultivation | Lettuce, tomatoes, carrots |
| Floriculture | Flowers and ornamental foliage | Roses, chrysanthemums, cut‑greens |
| Landscape Horticulture | Design, installation, and maintenance of gardens, parks, and green spaces | Trees, shrubs, lawns |
| Viticulture | Grape growing for wine and fresh consumption | Vitis vinifera, hybrid grapes |
| Herbology | Culinary, medicinal, and aromatic plants | Basil, lavender, ginseng |
| Plant Propagation | Techniques to reproduce plants (seed, cutting, grafting, tissue culture) | All horticultural species |

Sustainable Practices
| Technique | When Used | Key Steps |
|---|---|---|
| Seed sowing | Most annuals, many perennials | Select viable seed → treat (stratify, scarify) → sow in suitable medium → maintain moisture & temperature |
| Stem cuttings | Woody and herbaceous plants | Cut healthy stem → remove lower leaves → dip in rooting hormone → plant in moist medium |
| Layering | Difficult‑to‑root woody species | Bend low branch to soil, wound, cover with soil → roots develop → sever and transplant |
| Grafting | Fruit trees, roses | Join scion (desired variety) to compatible rootstock → secure with tape → maintain humidity until union |
| Tissue culture (micropropagation) | Mass propagation of disease |
