Sunlight Requirements
-
Full sun (6–8+ hours per day) is essential for strong growth and abundant fruiting.
-
In hotter climates, a touch of afternoon shade can prevent leaf scorch.
-
For containers, choose the brightest location possible—south-facing patios or sunrooms are ideal.
Watering & Soil
-
Water deeply when the top 2 inches of soil are dry.
-
Young trees need consistent watering, especially in the first 1–2 years.
-
Reduce watering in winter when the tree is semi-dormant.
-
Soil: Well-draining is critical. Use sandy loam or a high-quality citrus potting mix for containers.
Pro tip: Mulch around the base with 2–3 inches of organic material (keeping it a few inches away from the trunk) to help conserve moisture.
Fertilizing
All Simply Trees citrus arrive with a slow-release organic fertilizer already mixed into the soil—so don’t fertilize upon arrival.
For ongoing care:
-
Fertilize in early spring and midsummer using an organic citrus fertilizer such as Espoma Citrus-tone.
-
Avoid fertilizing in late fall or winter, which can push tender growth that risks frost damage.
Pruning & Maintenance
-
Prune lightly in late winter to early spring before new growth begins.
-
Remove crossing branches, weak growth, or water sprouts.
-
Maintain an open canopy to encourage airflow and reduce disease pressure.
-
Satsumas naturally have a rounded, compact habit—heavy pruning isn’t required.
Container Growing Tips
Satsuma citrus trees thrive in pots, especially in colder climates.
-
Pot size: Start with a 16–20 inch container for smaller trees, or a “Jumbo 5–6 ft” tree in a 10–15 gallon pot.
-
Drainage: Choose containers with multiple drainage holes.
-
Soil: Use a high-quality, well-draining citrus potting mix.
-
Mobility: In Zones 7 and colder, grow in containers so you can bring them indoors during freezing temps.
Cold Hardiness & Overwintering
One of the biggest advantages of Satsumas is their cold tolerance.
-
Arctic Frost & Orange Frost: Hardy down to about 15°F once established.
-
Owari: Hardy to about 18–20°F, making it ideal for Southern gardens.
Overwintering tips:
-
In Zones 8–10, Satsumas can stay outdoors year-round.
-
In Zones 7 and colder, bring containers indoors before temperatures dip into the mid-20s.
-
Indoors, place near a sunny window or supplement with grow lights. Water sparingly.
For in-ground trees in borderline climates, use frost cloths or covers during cold snaps.
Pests & Diseases
Satsumas are generally low-maintenance, but watch for:
-
Aphids, spider mites, or scale — wash off with water or treat with insecticidal soap or neem oil.
-
Leaf spot or sooty mold — usually linked to pest activity. Address pests first, then clean foliage.
Keep trees healthy with good airflow, proper watering, and seasonal pruning.
Harvesting & Fruiting Timeline
-
Fruiting age: Expect fruit in 2–3 years after planting (sometimes sooner in larger “Jumbo” sizes).
-
Ripening:
-
Owari typically ripens in November–December.
-
Arctic Frost and Orange Frost ripen in early winter, extending the harvest season.
-
-
Fruit is ready when skin color deepens and fruit feels heavy for its size.
Satsumas are naturally easy-peel, seedless mandarins—perfect for fresh eating or juicing.
