Growth Stages

1

Dormancy/Planting

2-4 weeks

Bare-root or container rose is planted with canes cut back to 12-18 inches; new growth begins to emerge from buds

Plant in early spring or fall. Remove any broken canes. Mound soil 8-10 inches around base in cold climates. Water thoroughly after planting.

2

Vegetative Growth

4-8 weeks

New shoots and leaves rapidly emerge and expand; plant establishes root system and builds cane structure

Remove any dead wood. Apply balanced fertilizer every 2-3 weeks. Mulch around base with 2-3 inches of organic material. Monitor for pests.

3

Budbreak & Flowering

Continuous spring through fall (8+ weeks per flush)

Rose produces flower buds on cane tips and lateral shoots; buds develop into characteristic red-and-white splashed blooms

Deadhead spent blooms above first 5-leaflet leaf to encourage more flowers. Feed with rose fertilizer or bloom-boosting formula. Ensure consistent watering.

4

Mid-Summer Stress

4-8 weeks (varies by region)

Growth may slow during extreme heat; flowering can diminish; plant may appear less vigorous

Increase watering frequency. Apply 3-4 inches of mulch to cool soil. Avoid fertilizing during peak heat. Provide afternoon shade in zones 8-9.

5

Fall & Hardening Off

6-10 weeks until frost

Growth resumes as temperatures cool; final flush of blooms appears; plant prepares for dormancy with thickened canes

Reduce nitrogen fertilizer; apply potassium-rich fertilizer to harden canes. Stop deadheading 4-6 weeks before first frost. Reduce watering gradually.

Companion Planting

Plan your garden →

Plant with:

Catmint (Nepeta) Salvia Lavender Alliums (ornamental onions) Delphiniums Lady's mantle (Alchemilla) Gaura Russian sage (Perovskia)

Avoid planting near:

Fennel (allelopathic; inhibits rose growth) Walnut trees (juglone toxicity) Cabbage family plants (compete for nutrients and attract similar pests)

Common Pests

  • Ensure good air circulation. Spray with sulfur or neem oil weekly at first sign. Remove affected leaves. Water at soil level only.

  • Remove infected leaves immediately. Do not wet foliage. Spray with copper fungicide or sulfur. Apply preventatively in humid climates every 7-10 days.

  • Spray with strong water stream. Use insecticidal soap or neem oil. Encourage beneficial insects like ladybugs. Repeat every 5-7 days as needed.

  • Increase humidity by misting plants (early morning only). Spray with neem oil or miticide. Ensure adequate watering and mulching.

  • Remove and destroy infected plants immediately. Control eriophyid mites (vector) with acaricide. No cure; prevention is key.

  • Hand-pick early morning. Use pheromone traps away from roses. Apply spinosad or pyrethrin spray. Row covers on new plants.

Harvest Tips

Cut blooms in early morning when petals are fully firm but just opened. Use sharp shears and cut at 45° angle above outward-facing 5-leaflet leaf node, leaving 12+ inches of stem. Place immediately in cool water with floral preservative. Roses last 7-10 days in a vase. Deadhead spent flowers regularly (every 2-3 days) to promote continuous blooming through the season.

Fun Facts

  • 🌱 The variegated striping pattern in Rose Splash can be unpredictable; some blooms may appear more red while others show more white, depending on temperature, light, and nutrient availability. Cooler weather tends to intensify the cream/white markings.
  • 🌱 Modern hybrid tea and floribunda roses like Rose Splash are the result of over two centuries of deliberate cross-breeding, combining characteristics from wild rose species native to Asia, Europe, and the Middle East.
  • 🌱 Roses have been cultivated for over 5,000 years and are one of the oldest and most beloved ornamental flowers; they hold cultural significance in nearly every civilization and remain the world's most commercially valuable ornamental plant.
