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
- Pruning: This is the best time to remove dead, diseased, and weak branches (dormancy).
- Plant protection: Usually not needed. If absolutely necessary, a dormant mineral oil may be applied.
- General care: A planting hole can be prepared for new plantings.
- Pests & diseases: Do a general check of the trunk and branches.
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: Before the buds wake up, a copper-based preparation can be applied as a precaution.
- General care: This is a suitable month for planting.
- Pests & diseases: Check branches for oak eggar moth egg masses.
- Frost risk: Protect newly planted seedlings from severe frosts.
March
- Watering: Only for newly planted seedlings, 10 L/week if it stays dry; reduce if there is rain.
- Fertilizing: Absolutely not needed.
- 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.
- General care: Remove weeds around the base of young plants.
- Pests & diseases: Check the branches and trunk for brown, fixed bumps (scale insects).
- Frost risk: Late frosts can damage young shoots.
April
- Watering: For new seedlings, 10-15 L/week; not needed for mature trees; reduce if there is rain.
- Plant protection: If powdery mildew appears, sulfur can be applied.
- General care: Gall formations are normal, do not harm the plant and require no intervention.
- Pests & diseases: Observe insect activity on the leaves.
May
- Watering: For new seedlings, 15-20 L/week; no watering is needed for mature trees.
- 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.
