🌲 Rose

Roses thrive in fertile, humus-rich, well-drained soil that retains moisture without becoming soggy. Potting soil is ideal; incorporate plenty of compost or well-decomposed manure before planting, and maintain an organic mulch. pH should be slightly acidic or neutral (approx. 6.0-7.0). On heavy clay soils, improve drainage and structure with organic matter and consider raised beds; on very sandy soils, add organic matter to increase water and nutrient retention. Avoid poorly drained sites where roots remain in the damp in winter.

Roses (Rosa spp.) are not usually "sown" as garden plants; they are more reliably propagated vegetatively (cuttings, buds or grafts). Seedlings are mainly used for breeding, as they vary considerably and take longer to flower. Vegetative propagation (recommended): - Softwood cuttings (late spring to early summer): Take non-flowering 10-15 cm cuttings from healthy shoots. Remove flowers/ buds and lower leaves, keep 2 or 3 leaves at the top and make a clean cut just below a node. - Hardwood cuttings (late autumn to winter, dormant season): Take mature stems 15 to 25 cm thick. Remove leaves, cut just below a node at the base and above a node at the top. - Rooting: Soak the base in rooting hormone, insert in a free-draining medium (e.g. coarse sand/perlite with peat/clay) with at least one node below the surface, firm up and water. - Environment: Keep the medium evenly moist, but not soaking wet. For softwood cuttings, maintain high humidity (propagator/clear cover, ventilate to reduce fungal problems) and bright, indirect light; avoid hot sun. - Aftercare: Re-pot once roots have taken root and growth is strong; harden off before planting. Seed propagation (for breeding/experimentation): - Collect mature hips, extract seeds and clean pulp. - Cold stratification to break dormancy: keep seeds moist (not wet) in a sealed bag with humid medium in a refrigerator around 1-5°C for several weeks to a few months. - Sow shallowly in a sterile, non-draining seed mixture; store at cool to mild temperatures with constant humidity. Germination may be slow and irregular. Planting (grafted or clean-rooted plants): - Plant in full sun and fertile, well-drained soil. - Plant so that the graft union (bud union) is at or just below ground level in colder climates (to protect from frost) or around ground level in milder climates. - Keep well watered, mulched and deep-watered regularly during the establishment period.

Test the soil before fertilizing; roses perform best in moderately fertile, well-drained soil. Apply a balanced rose fertilizer or general-purpose fertilizer in early spring, when new growth begins. Repeat light applications during active growth (approximately every 4 to 6 weeks) until midsummer; in warm climates, application may continue a little longer if plants are still growing. Stop nitrogen-rich fertilization 6-8 weeks before the first average frost to avoid tender, late growth; a low-nitrogen, high-potassium product can be used at the end of the season only when necessary to promote ripening. Water abundantly before and after fertilization and avoid granular fertilizers touching the foliage; avoid over-fertilization to reduce salt damage and excessive soft growth. Use compost or well-decomposed manure as annual potting soil or mulch to improve soil organic matter; in containers, use a controlled-release fertilizer and supplement with occasional liquid feed according to label rates.

Mulch roses with 5 to 8 cm of organic matter (well-decomposed compost, leaf mold or shredded bark) to conserve moisture, moderate soil temperature and suppress weeds. Apply mulch in spring, after the soil has warmed up, and again in autumn/winter when winters are mild. Keep the mulch a few centimetres from the crown/cane (do not pile it up against the canes) to reduce the risk of rot and disease. Water the soil before mulching, top it up as it decomposes, and avoid fresh/unfinished manure or thick, compact layers that can prevent air circulation.

Roses (Rosa spp.) have a history of medicinal use, most often via the rose hips (fruit) and petals. Rose hips (particularly those of the dog rose, Rosa canina) are rich in vitamin C and polyphenols, and are used as antioxidant and anti-inflammatory preparations; standardized rose hip powders/extracts have been studied for the symptomatic treatment of osteoarthritis (modest reduction in pain and stiffness in some trials). Rosehip teas and syrups are also traditionally used for colds and general convalescence. Rose petals and rose water have mild astringent, soothing and anti-inflammatory properties and are used topically for minor skin irritation and as a gentle rinse for the mouth and throat; petal infusions are traditionally used for mild gastrointestinal disorders. Rose essential oil is used in aromatherapy for relaxation and can help reduce short-term anxiety in certain contexts.

Rose infusions (usually made from dried petals or rose hips) are traditionally used as a mild, caffeine-free tea. Rosehip tea is prized for its high content of vitamin C and antioxidant polyphenols, which support immune function and exert antioxidant activity; it is also used for its mild anti-inflammatory effects (including joint comfort). Rose petal infusions are mildly astringent and soothing. They are commonly consumed for minor irritation of the throat and mouth, for gentle digestive support and for their calming, aromatic effect.

Most garden roses are pruned in late winter or early spring (when buds swell) to shape the plant and stimulate the emergence of vigorous new flowering shoots. Start by eliminating all dead, diseased, damaged and weak wood, then remove shoots that cross or intertwine, as well as shoots below the graft (suckers). Open the center to allow air to circulate and keep 3 to 6 of the strongest stems. Shorten the remaining stems to the outward-facing buds, making clean, angled cuts about 6-8 mm above the bud; if a stem is old or unproductive, cut it back to the healthy white pith or remove it at the base to encourage new basal shoots. After main pruning, remove spent flowers during the season to encourage repeat flowering; single-flowering varieties are usually pruned just after flowering rather than at the end of winter. For roses that bloom several times a year, it may be advisable to prune lightly after each flowering.
