🌿 Certified organic cultivation • 🍇 Sweet-tart mulberries from July to September • ☀️ Sun / Partial shade • ❄️ Hardy down to -15 °C • 🐾 Non-toxic • 📏 H45 cm | Pot Ø13 cm
Morus nigra 'Mulle', or Korean black mulberry, is a small organic fruit tree native to Korea, selected for its compact habit and abundant crop of juicy, sweet-tart mulberries. Its dark green deciduous foliage — turning golden yellow in autumn — and rounded silhouette make it a reliable choice in the fruit trees and herbs collection, perfect for balconies and terraces as well as small urban gardens.
Self-fertile and suited to pots as well as open ground, it is one of the most accessible fruit trees for combining good looks with a tasty harvest, even without a large garden.
Light & placement
The 'Mulle' mulberry thrives in full sun but tolerates bright partial shade — it grows well in a large deep container or well-drained open ground. A warm spot sheltered from cold winds extends the harvest season.
- Exposure: full sun or partial shade (minimum 4 to 6 hours per day).
- Location: balcony, terrace, patio, small garden — in a deep pot or open ground.
- Soil: rich, light, well-drained — tolerates most garden soils.
- In a pot: container at least 40 cm deep, well-drained.
Against a south-facing wall, the heat accumulated during the day intensifies the fruit flavor and can advance the harvest by two to three weeks.
Watering & care
Once established, the black mulberry requires little intervention. In pots, be careful not to leave the substrate waterlogged in winter — excess water during cold periods is the main cause of decline. An organic fertilizer application in spring is enough to support fruiting.
- Watering: regular in summer, very sparse in winter — let the substrate dry between waterings.
- Pruning: in November-December on bare wood — remove crossing branches, shorten the longest by one third.
- Fertilizer: organic in spring for pots — unnecessary in well-amended open ground.
- Mulching: 8 to 10 cm at the base in open ground to retain moisture and naturally nourish the soil.
Harvest by hand when the fruits come away easily — ripe mulberries leave lasting stains, so avoid light-colored surfaces under the tree.
Decor ideas & plant pairings
The contrast between the rough dark green foliage of the mulberry, its bright red-black fruits, and its rounded structure creates an atmosphere both rustic and graphic, ideal for a Mediterranean garden or an outdoor jungle.
- For an edible terrace with two harvests, pair it with the organic blueberry 'Reka' — similar size, shiny foliage contrasting with the mulberry's rough leaves, and two complementary harvest seasons.
- In a large container on a balcony, a terracotta ceramic decorative pot matches the red-black tones of the summer fruits and the golden yellow of the autumn foliage — a warm and coherent palette throughout the season.
- For a structured urban orchard in open ground, the 'Black Satin' thornless blackberry with its spreading, shrubby habit contrasts in silhouette with the more upright 'Mulle', while extending the harvest into autumn.
- To complete the composition with spring color, the organic raspberry 'Malling Promise' provides white blossoms and an early summer harvest before the mulberry reaches maturity.
The mulberry loses its leaves early in autumn, revealing some small decorative orange fruits that persist on the branches — place it in a spot visible from indoors to enjoy this display after the season.
Verdeia tips
- Keep the soil slightly moist throughout fruiting: water stress in July-August causes premature fruit drop before full maturity, significantly reducing the weight and flavor of the harvest.
- Prune on bare wood, ideally in November-December: pruning once all the leaves have dropped lets you see the tree's structure more clearly, identify the branches to remove and get cleaner healing before winter dormancy.
- Repot only when the roots grow out of the drainage holes: the mulberry fruits better when slightly root-bound — premature repotting stimulates vegetative growth at the expense of fruit.

FAQ – Everything to know before adopting your Verdeia plant
How are my plants prepared before shipping?
All our plants are selected from our European partner nurseries. Before shipping, they are watered, cleaned, and protected with breathable, secure packaging. Each package is designed to ensure your plant arrives in perfect health, without any transport-related stress.
Will the plant look exactly like the photo?
The photos accurately represent the variety and the stated size. Since each plant is unique, slight differences in shape, foliage, or color may occur — and that’s part of their charm.
What are the delivery times and conditions?
Orders ship within 48 working hours, with tracked delivery in 2 to 5 working days via DPD. Shipping costs and the free-shipping threshold depend on your country — see our delivery page. You receive a tracking link as soon as your parcel leaves.
What should I do when my plant arrives?
Open your package as soon as you receive it and carefully remove the plant from its packaging. Let it acclimate for 24 hours in its new environment before watering. If it has been slightly stressed during transport, it will recover its shape after one or two days in the light.
What should I do if my plant arrives damaged?
Contact us within 48 hours with a photo of the issue. Our team will assess the situation and offer you the best solution: replacement, partial refund, or recovery advice.
Can I return a plant?
Since plants are living beings, standard returns are not possible. However, we guarantee good health upon delivery: if the plant arrives damaged, it will be replaced free of charge. For any other cases (order error, decorative pot, accessory), returns are possible within 14 days.
