Tree Heath Care

Erica arborea

An evergreen shrub native to the Mediterranean basin, with fragrant flowers. Its most important requirement is acidic (lime-free), well-drained soil; in Manisa's alkaline soils it can suffer chlorosis (yellowing), so it requires special soil preparation.

Half-hardy · -15 °C / 5 °F

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

General care: The plant is in dormancy; refresh the acidic mulch (pine needles) in the root zone.
Pests & diseases: Against the risk of root rot, make sure drainage is good.
Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -15 °C.

February

Pruning: Not done; flowering time is approaching.
General care: Flowering begins.
Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -15 °C.

March

Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
Fertilizing: Apply a balanced fertilizer or well-rotted organic fertilizer once when it wakes from dormancy. It loves acidic soil; if interveinal yellowing (chlorosis) appears on the leaves in limy soil, prefer an acidic fertilizer.
General care: Suitable period for planting and transplanting. Flowering continues.
Pests & diseases: If chlorosis (yellowing between the leaf veins) begins, apply iron chelate.

April

Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
Fertilizing: Not necessary (if done in March).
Pruning: After flowering ends, lightly cut the spent flowering branches to maintain the plant's form and keep it compact; do not cut into the woody parts.
General care: Suitable period for planting and transplanting. Flowering continues.

May

Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
Pruning: This is the last chance for pruning.
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: Suitable period for planting and transplanting. Flowering continues. Drainage is critical for this plant. In heavy, water-retaining soil, plant on a mound or bed raised 20-30 cm; the root collar should remain above the surrounding soil level.
Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.

June

Watering: In a long drought, water deeply once a month.
Pruning: Prune as soon as flowering ends. Next year's flower buds form over the summer; late pruning reduces flowering. After flowering is complete, do light shaping. Avoid heavy pruning; old wood does not renew thoroughly. On fine-branched forms, cutting with blunt shears is suitable.
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: Heat stress begins; a mulch layer keeps the roots cool.
Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.

July

Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. Water the area around the roots to a depth of 15-20 cm.
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: This is the hottest month; the plant may become stressed.
Pests & diseases: In hot and dry weather, look on the undersides of the leaves for fine webbing and speckled yellowing (spider mites). Washing the leaves during the cool hours reduces their numbers.

August

Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. Water the area around the roots to a depth of 15-20 cm.
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.
Pests & diseases: In hot and dry weather, look on the undersides of the leaves for fine webbing and speckled yellowing (spider mites). Washing the leaves during the cool hours reduces their numbers.

September

Watering: In a long drought, water deeply once a month. Water newly planted specimens more often than established plants during the first year; the root system is still shallow.
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: Good time for planting and transplanting.
Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.

October

Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
General care: Good time for planting and transplanting.
Pests & diseases: Pay attention to drainage against root rot.

November

Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
General care: Suitable period for planting and transplanting. Make sure water does not pool in the root zone during winter rains; for this plant, drainage is more critical than irrigation.

December

General care: Evergreen leaves continue to lose water in winter. Water thoroughly once before the soil freezes.
Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -15 °C.
