Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1 tbsp around the base of each plant and work lightly into the topsoilPruning
- Prune dead, damaged, or diseased branches in late winter before new growth emerges
- Thin crowded stems to improve air circulation and increase sunlight penetration for better fruiting
- Remove suckers growing from the base to maintain the desired shrub shape and prevent overcrowding
