Apply Osmocote / controlled-release fertilizer to the balcony planters, and do a light balcony-plant trim/prune in the same maintenance pass if needed. Osmocote: use 2 tablespoons per planter. Scatter/top-dress evenly around plants, keep a few cm away from stems/trunks, and lightly scratch/mix into the topsoil if easy. Do not dig deep or damage roots. Osmocote is fertilizer, separate from Confidor/pest treatment. Reapply about every 6 months; exact product label wins. Trim/prune: remove dead/dry growth and lightly shape overgrown plants. Keep it conservative; avoid heavy pruning unless a plant clearly needs it. Balcony watering is automatic, around 15:25 and around 06:00, so no separate one-off watering reminder is needed by default.
