Pearl Bush Care
Exochorda
A deciduous shrub known for its pearl-like buds and pure white flowers in spring. Manisa's chalky soils and hot summers are challenging for it; it needs well-drained, slightly acidic soil, afternoon shade and regular summer watering.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Pruning: While the plant is dormant, rejuvenation pruning can be done by cutting old, unproductive branches back to the base.
- General care: The plant is in dormancy.
- Fertilizing: At the end of the month, a slow-release fertilizer or compost may be applied for acid-loving plants (do not overfeed).
- Pruning: This is the final period for pruning.
- General care: It is getting ready to wake; clean the surroundings.
- Watering: If the rains are insufficient, start watering with lime-free water.
- Fertilizing: If it was not given in February, give it at the start of this month.
- General care: Leaves and pearl-like flower buds form.
- Pests & diseases: If chlorosis (leaf yellowing) begins, apply iron chelate.
- Watering: If there is no rainfall, water every 15 days.
- General care: Main flowering period.
- Pests & diseases: Check for aphids.
- Watering: If there is no rainfall, water once a week.
- Pruning: The most important care time is as soon as flowering ends; shorten the flowering branches by about one third and remove old branches at the base. Never prune in fall or winter.
- General care: Spread a 5-7 cm layer of mulch over the root zone; it retains soil moisture and suppresses weeds. Do not pile mulch against the trunk.
- Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water around the roots to a depth of 15-20 cm.
- Pruning: Not done; it is too late.
- Plant protection: Start checking for spider mites.
- General care: Heat stress begins; it is vital that it gets afternoon shade.
- Pests & diseases: The risk of leaf scorch is high.
- Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water around the roots to a depth of 15-20 cm.
- Fertilizing: Never given.
- Pruning: Prune as soon as flowering ends. Next year's flower buds form over the summer; late pruning reduces flowering.
- Plant protection: The spider mite population may increase.
- General care: This is the most challenging month.
- Pests & diseases: Heat stress and leaf scorch are the biggest threats.
- Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water around the roots to a depth of 15-20 cm.
- Plant protection: Do not stop checking for spider mites.
- General care: The plant is in survival mode.
- Pests & diseases: Stress-related leaf drop may be seen.
- Watering: If there is no rainfall, water once a week.
- Pruning: Remove only branches that dried out in summer.
- General care: The best time for planting new seedlings; acidify the soil with sulfur, peat or pine needles.
- Watering: If there is no rainfall, water every 15 days.
- General care: Tree and shrub planting can continue; leaves change color and begin to drop.
- Pests & diseases: Against the risk of root rot, pay attention to the drainage of newly planted plants.
- General care: Collect fallen leaves; many disease agents and pests overwinter under leaves.
- Pruning: If needed, shaping pruning may be carried out.
- General care: The plant is fully dormant.
