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.

January

Watering: Not needed if the winter rains are sufficient; prevent the soil from drying out completely.
Pruning: Not done. Pruning in winter causes the loss of the spring catkins.
Plant protection: Apply dormant mineral oil if needed.
General care: Cover the root zone with acidic mulch (pine needles).
Pests & diseases: Watch out for the risk of root rot.

February

Pruning: While dormant, remove dry, broken, crossing and inward-growing branches so that air and light reach the inside of the crown.
Plant protection: Avoid spraying during the flowering period.
General care: Catkins (flowers) open.
Frost risk: Flowers can be sensitive to frost.

March

Watering: If the soil begins to dry, water abundantly (30-40 L/week), use lime-free water; reduce if there is rain.
Fertilizing: Fertilizer or iron sulfate may be applied for acid-loving plants; do not overapply.
Pruning: Main pruning time. Prune immediately after the catkins have finished. To keep the plant young, you can cut hard back (coppicing).
General care: Pruned branches can be easily propagated from cuttings.
Pests & diseases: Check the new shoots for aphids.

April

Watering: If there is no rainfall, water 1-2 times a week.
Fertilizing: If there are signs of chlorosis (yellowing), give iron chelate; do not overdo it.
Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
