The Production of Oud Seedlings

Between the seed that germinates and the tree that is moved to its permanent land, there extends a quiet intermediate stage whose mention is often abridged: the stage of the seedling. In this stage the newborn plant is raised in the nursery until it strengthens and its stem grows firm. In this article we present a general educational overview of the production of oud seedlings — how the plant is moved from the stage of the seed to a seedling ready for transplanting — in descriptive, reserved language, in which we describe what is circulated in general, without claiming an agricultural expertise in the nurseries or the farms.

1. From the seed to the seedling

When the oud seed germinates and its first leaves appear, it has not yet become a tree; it is a tender newborn plant that needs a whole stage of care before it is moved to its land. This stage is what we call the production of seedlings: an intermediate stage that begins where the planting of oud seeds and their germination end, and extends until the plant becomes a strong seedling able to face the conditions of the open ground. The seed gave us a plant, and the nursery takes on the transforming of this plant into a seedling that is relied upon.

And the importance of this stage is that it is a link that cannot be skipped in the cultivation of oud trees. The newborn plant is too weak to be planted directly in an exposed land, where the strong sun, the fluctuation of conditions, and the competition of weeds and pests. Therefore it is raised first in a protected, managed environment resembling an incubator in which it grows at its leisure, until it reaches a measure of strength that allows its transplanting. And this gradation — from a seed to a plant to a seedling to a tree in the ground — is what makes cultivation a deliberate journey, not a single leap.

And we alert from the outset that what we present here is a general description of the nature of this stage, not a step-by-step technical guide. The precise details of raising the seedlings — of timing, conditions, and daily care — differ with the difference of the species, the location, and the nursery, and they are the affair of the people of specialization. As for us, we draw the greater picture that helps the reader to understand how the oud seedling is raised before it becomes a tree.

2. The environment of the nursery

Oud seedlings are usually raised in a nursery that provides them a protected, managed environment, away from the harshness of the exposed ground. And the general circulated picture is that these young seedlings are kept under a partial shade that protects them from the strong direct sun while they are tender, in a warm, humid atmosphere that imitates what oud trees grow in in the wild under the canopy of the forest. The small plant, like many of the plants of the forest, begins its life in the shade, not in the full sun.

And this partial shade is not a marginal detail, but is an extension of what we know about the climate suitable for cultivating oud, warm and humid, but on the level of the nursery and the single seedling this time. The nursery tries to reproduce the character of the environment of the forest in a managed space: a stable warmth, a preserved humidity, and a protection from the scorching sun, the winds, and the sudden aridity. And this early protection is what grants the seedling an opportunity to grow without being strained by harsh conditions before its time.

And we deliberately avoid here mentioning any shading percentages, or specific degrees of heat and humidity, because they are technical details that vary from one nursery to another and from one species to another, and describing them precisely is the affair of the agricultural specialist, not the supplier. We content ourselves with the qualitative principle: a protected, warm, humid environment, a partial shade in the first stage, and a protection from extremity. As for adjusting these elements with numbers, its reference is the people of the nurseries who balance between them according to the species and the location.

3. The containers and the growing medium

The seedlings are raised in the nurseries often in individual containers or bags containing a suitable growing medium, rather than being left in shared flats. And the advantage of this is that each seedling grows in its own space with its roots, so its care and its transplanting later become easy without a great strain on its roots. And the general picture is that the growing medium is chosen to be warm, preserving the humidity, well-drained at the same time, not trapping stagnant water that harms the young roots.

And we deliberately avoid here mentioning a recipe for the growing medium with its components and their proportions, or the size of the containers in dimensions, because these details differ from one nursery to another and from one species to another, and are not among what we assert as suppliers. The general principle suffices us: an individual container that grants the roots their space, and a growing medium that gathers between the preservation of humidity and the goodness of drainage. As for the precise composition, it is the affair of the agricultural specialist who knows what suits his seedlings in his environment.

And the essential idea is that the choice of the container and the medium is not a random matter, but a part of preparing a small environment that suits a sensitive seedling: a warmth that encourages growth, a humidity that prevents drying, and a drainage that protects the roots from rot. And this care for the micro-environment around each seedling is what prepares it to move later to the permanent ground with sound roots, which is what makes the nursery stage an investment in what follows it of stages.

4. The care of the seedlings

After the seedling settles in its container within the nursery, a stage of continuous care begins until it strengthens. And the general circulated picture is that this care revolves around three axes: an irrigation that preserves the humidity of the medium without a drowning that chokes the roots, a management of the light that begins with the partial shade then gradates with the growth of the seedling toward a more abundant light, and a protection from the pests, the competing weeds, and the harsh conditions. The seedling in this stage needs a regular monitoring more than it needs a great intervention.

And we abide here by the same reservation: we will not mention an irrigation schedule of amount or frequency, nor a specific intensity of light, nor a program for combating a particular pest, because these are matters that vary widely according to the species, the climate, the season, and the state of the seedling, and any number we cite may be understood as a guaranteed recipe when it is not so. The qualitative description suffices us: a preserved, not excessive humidity, a light managed by gradation, and a vigilant protection. As for the precise details, they are the affair of the specialized nursery that reads the state of its seedlings day by day.

And among what is observed in this stage is the protection of the young seedlings from the pests and diseases that may afflict them while they are tender. And this is a subject standing on its own with its details; we will devote to it an independent axis within this guide about the pests of oud trees and their diseases and link it here when it is completed. As for in this article, we content ourselves with pointing out that the protection is part of the care of the nursery, without entering into a diagnosis or a treatment that is not our specialization, leaving that to the people of agricultural experience.

5. When is the seedling ready?

A natural question recurs: when does the seedling become ready to be moved from the nursery to the ground? And the honest answer is that the readiness is usually measured by the strength of the seedling and its firmness, not by a specific age we assert. The ready seedling — as is described generally — is the one whose stem has grown firm, whose root has strengthened, and whose growth is cohesive, such that it is likely to tolerate the conditions of the open ground after it has spent in the nursery enough time to become cohesive.

And we deliberately avoid here mentioning a height for the seedling in centimeters, or an age for it in months, as a decisive sign of the readiness, because that varies widely according to the species, the conditions of raising, and the speed of growth, and any number we cite may be understood as a fixed criterion when it is not so. The truer criterion is qualitative, not numerical: a strong, cohesive seedling whose capacity to tolerate the transplanting is trusted, not a seedling that has reached a particular number.

And we put all this forward as a general principle, not a technical judgment we issue; for estimating the readiness of the seedling exactly is the affair of the specialized nursery that sees its seedlings and examines their state. What matters conceptually is that hastening to move a seedling that has not yet strengthened is a risk that may cost it, and that patience with it until it grows firm is part of the success of the whole journey. This is why the readiness is regarded as a state that is read, not a date that is calculated.

6. Hardening before transplanting

Before the seedling is moved from the warmth of the nursery and its protected humidity to the exposed ground, it is mentioned generally that it passes through a preparatory stage known as hardening or acclimatization. And the general idea is that the seedling be accustomed gradually to conditions closer to what it will face in the ground — a more abundant light, and a less protected atmosphere — rather than being moved suddenly from a protected environment to a harsh environment so it is stricken with a shock. The gradual transition is gentler on the seedling than the sudden transition.

This is a conceptual description of a practice circulated in the raising of many seedlings, not a numerical rule we set. And we avoid here mentioning a duration for the hardening in days or steps specified in detail, because that differs with the difference of the species, the conditions, and the nursery, and it is the affair of the agricultural specialist. The principle suffices us: a gradual accustoming that prepares the seedling psychologically — if the expression is correct — and physiologically for what is after the nursery, so that the transplanting is not a sudden shock.

And with this stage the task of the nursery ends practically, and a new stage begins, which is the transplanting of the seedling to its permanent place in the ground. And this stage — the transplanting of the seedlings — is a subject standing on its own with its care and its details that exceed the bounds of the nursery, and we will devote to it an independent axis within this guide about the transplanting of the seedlings to the permanent ground and link it here when it is completed. As for in this article, we pause at the bounds of the ready, hardened seedling, keen not to mix between one stage and another.

7. The conclusion

We can summarize what precedes in a single principle: the production of oud seedlings is a precise work that needs skill and patience, whose axis is that the newborn plant is raised in a nursery that provides it warmth, humidity, partial shade, and protection, until it strengthens and grows firm and becomes ready for transplanting. This is the essence of what can be said with honesty about this stage of the cultivation of oud trees, without entering into precise numbers that are not our specialization.

And we repeat what we began with: we are suppliers, not a nursery nor an agricultural center, and what we presented is a general educational picture. As for the precise details of raising the seedlings — of durations of stay in the nursery, shading percentages, irrigation schedules, and criteria of readiness — their reference is the agricultural specialists, the nurseries, and the extension services in each country, and they are the people of this affair to whom we refer whoever intends an actual production of seedlings.

As for if your interest in oud is as a product, not a cultivation, the conclusion is simpler and closer: the piece that reaches you was one day a small seedling raised in a nursery before it became a tree that produces oud. And for whoever wants to distinguish the authentic and choose well, we have set a practical guide in how to choose authentic Indonesian oud, and better than that is that you try for yourself, so you begin with a sample of oud in which you sense the fruit of that long journey in your hands.
