Transplanting Seedlings

Transplanting involves moving seedlings from the seedbed to the ground as quickly as possible to promote faster growth. For successful transplantation, the seedlings must have a well-developed root system and at least two or three leaves. Otherwise, they will struggle to grow. The day before transplanting, both the soil and seedlings should be thoroughly watered. During the process, a transplanter is used to extract the seedlings along with the surrounding soil, minimizing root disturbance.

There are different methods for transplanting vegetables, each suited to specific plant types and depths. Regardless of the method, it is crucial to dig a hole wide and deep enough to allow the roots to spread naturally without bending. The main transplanting methods include:

  • At Ground Level: The seedlings are placed so that the soil does not cover the leaves. This method is suitable for vegetables like chard, beets, artichokes, celery, chicory, strawberries, lettuce, and thistles.
  • Slightly Deep: The seedlings are buried up to the first leaf. This method is used for leeks, onions, cucumbers, gherkins, cauliflower, pumpkins, melons, and watercress.
  • Deep Transplanting: The plant stems are positioned vertically in the soil for optimal growth.


Transplanting can be done periodically to ensure a continuous harvest. For example, carrots can be planted in early May and then every twenty days thereafter. This staggered planting schedule allows for a first harvest in early October and subsequent harvests every twenty days, ensuring a steady supply of fresh produce.

Methods of Plant Propagation

Some vegetables do not reproduce well from seeds and are better propagated through plant parts. Examples include artichokes, garlic, potatoes, sage, and rosemary. It is important to select healthy and vigorous "mother" plants to ensure successful propagation. Depending on the plant type, the following parts can be used for multiplication:

  • Bulbs: Swollen underground buds (e.g., garlic).
  • Tubers: Enlarged underground stems rich in nutrients (e.g., potatoes).
  • Stolons: Horizontal branches that develop roots and form new plants.
  • Rhizomes: Horizontal underground stems.
  • Shoots: Offshoots from the base of the plant, commonly used for artichokes.

Propagation Techniques

  • Cuttings: This method involves taking parts of branches, shoots, roots, or leaves, which can grow into a new plant under the right conditions.

    • Woody Cuttings: Taken during the dormant season from shoots, branches, or roots. These are mainly used for fruit plants.
    • Herbaceous Cuttings: Taken from leaves or soft stems, suitable for non-woody plants.

  • Grafting: In this method, a bud or twig from one plant is joined to the stem of another plant. Grafting is used to enhance fruit quality, strengthen branches, or propagate plants that cannot be grown from seeds or cuttings.

  • Layering: This involves wrapping a branch at the point where new roots are desired with soil or peat moss. A ring of bark is removed, or a longitudinal cut is made at the chosen spot. A small object is inserted to keep the wound open, promoting root growth. This technique is typically done in spring.

Seedling Management Techniques

  • Thinning: This practice controls the density of young seedlings to ensure they receive adequate light and space to grow. Seedlings that have reached a certain height are carefully removed from the seedbed and transplanted to a different location, allowing each plant enough room to develop.

  • Thinning in the Seedbed: This early transplanting occurs shortly after germination. Seedlings are lifted using a small stick with a U-shaped tip and replanted at 5 cm intervals. Using trays with compartments filled with compressed peat is recommended. These trays should be kept in the shade and watered sparingly. Once the stems appear, watering should be done with a fine spray, and the glass cover gradually removed to acclimate the seedlings before the final transplant.

  • Row Thinning: Involves removing excess seedlings planted in rows to prevent overcrowding. This is typically done alongside weeding and is beneficial for onions, spinach, carrots, turnips, and lettuce.

Pruning Techniques

Pruning is essential for directing plant growth, enhancing fruit production, and shaping ornamental plants. In horticulture, pruning includes:

  • Pinching: Removing the tips of branches or the main stem at specific heights to encourage lateral growth and increase fruit production.
  • Fruit Thinning: Eliminating shoots that do not bear fruit to promote the growth of productive branches.

Mounding

Mounding involves piling soil at the base of plants to:

  • Keep plants upright, preventing damage from wind or rain.
  • Protect roots from cold temperatures.
  • Aid in irrigation and drainage.
  • Encourage the blanching of certain vegetables (e.g., leeks, asparagus, and endives) by shielding them from sunlight.

This technique is particularly useful for crops like potatoes, beans, and cauliflower, as it enhances root stability and overall plant health.

The 12 Months of the Garden: From Seed to Harvest

Garden Time: Your Monthly Manual for Healthy Soil, Successful Growing, and Natural Pest Management Introduction   Since the dawn of time, humans have felt an innate pull toward the land. Legend tells us that Adam was the first gardener, and from that moment forward, the desire to cultivate has lived within us all. At least once in his life, every person has imagined the satisfaction of growing food with their own hands. This book is for those who have never taken the leap into gardening, as well as for those who, having tried and failed, have come to believe that only others possess the elusive "green thumb."   Modern life has distanced us from nature. The path to urbanization has led many to forget that our survival is intertwined with the earth’s rhythms. Yet, deep within, there remains a nostalgia for simpler times—a connection to the way our ancestors lived, growing their own food and depending on the land. Perhaps this is why so many of us instinctively crave fr...

Soil and Cultivation Techniques: The Foundation of Thriving Agriculture

Image
Analyzing, Preparing, and Cultivating Soil Before any successful cultivation can begin, the soil must be carefully prepared. This process starts with the removal of deep-rooted weeds, such as brambles, nettles, and other persistent vegetation that resist superficial clearing. A thorough soil assessment follows, ensuring that it is not only free from obstructions but also enriched for optimal plant growth. A scientific soil analysis, conducted in a laboratory, provides key insights into its composition. Factors such as climate, sun and wind exposure, geographical origin, and the availability of nearby irrigation sources play a crucial role in determining the soil's fertility. However, beyond lab results, nature itself offers valuable clues—observing the native wild plants and even the texture and color of the soil can reveal much about its quality and nutrient balance. The Role of Microorganisms and Soil Composition Beneath the surface, an entire ecosystem of microorganisms works ti...

Irigation and Crop Rotation

Image
Seeds can only germinate in a moist environment, and roots absorb essential nutrients when dissolved in water. Unless the season is particularly rainy, watering is the first and foremost task for any horticulturist who has sown or planted. This practice is especially crucial for transplanted vegetables or those that have suffered root damage, as they may struggle to adapt to their new environment. After planting or transplanting, water the soil at the base of the plant while keeping the aerial parts dry. This is particularly important when plants are not yet deep enough to access moisture naturally. Ideally, watering should be done in the morning and late afternoon. If using a hose, opt for a spray or "rain" setting to reduce water pressure, as a strong jet can compact the soil and make it less permeable to air. In the absence of proper irrigation tools, small seed containers can be watered using a bottle with several small holes punched in its cap. Avoid watering in direct ...
