The editor introduces topics related to the Queen of Sweden rose, including its advantages and disadvantages and daily maintenance. Details are as follows:
Chinese Name: Queen of Sweden
English Name: Rosa "Queen of Sweden"
Cultivation: By UK's Austin
Year of Cultivation: 2004
Required Sunlight Duration: Over 4 hours
Characteristics: Upright and clustering growth; large shrub with vine-like traits; flower diameter 8cm, about 41 petals, light pink; fragranceless; few thorns, leaves round and inwardly curled; fewer flowers in the first year, more flowers in the second year with a group bloom; flowers become smaller in hot weather, short single flowering period at high temperatures; pruning is required after flowering to promote reblooming; suitable for cut flower production, garden landscaping, and large pot planting for ornamental purposes. Flowers become smaller in summer, and adequate watering is needed during flowering to prevent easy wilting; apart from top dressing after flowering, light fertilization is sufficient.
Large shrub variety, can grow up to 2 meters tall if left unattended; for potting, start with 3 gallons, transition to 5 gallons, and settle at 7 gallons; it is recommended to control the pot size to 5 or 7 gallons (the queen's root system is quite developed and 3 gallons is too small), pruning and controlling the plant while also dealing with the roots during winter dormancy (up to 1/4-1/3 of the root length can be pruned).
The queen's flowering branches are actually quite long, so don't just cut a little when pruning after flowering. Retaining branches of 40-60 cm in length is more conducive to reblooming. (Apply high-phosphorus and potassium fertilizer promptly after pruning, as the root system is robust and requires a lot of fertilizer)
In September, with high temperatures, the queen still has many flower buds at the branch tips;
There are several reasons that affect the queen's reblooming:
1. Insufficient sunlight (requires over 4 hours of light)
2. Improper pruning (refer to the figure below)
3. The queen's leaves are round and inwardly curled, which are prone to red spider mites. If not treated promptly after getting mites, it will affect flowering
4. Too small a pot, the roots have filled the pot with no room to grow, affecting flowering
5. Lack of fertilizer, the more developed the root system, the higher the demand for fertilizer
6. The queen is suitable for slightly dry conditions (except during the爆发 of suckers and buds), excessive water for a long time affects growth and flowering.
7. High-phosphorus and potassium fertilizer should be applied after pruning
