Synonymous with "late planting" with seed trees, it is the biggest obstacle to investing in horticulture. Field data shows that gardens built with seed seedlings may not even have a salable product for the first 5 years; As a result, all the costs of irrigation, fertilizer and spraying remain without return of capital.

But in crown grafting of mature trees, you have a whole tree with a well-developed root system. The root immediately feeds the scion and the fruit production process begins in the second or third year. This speed in making money not only compensates for the higher initial cost of transplanted seedlings, but also saves the gardener from the risk of uncertainty for several years.

3) Risk management: predictability versus genetic lottery

Seed seedlings are the result of the genetic combination of a specific mother tree with an unknown father base. This "sexual diversity" is the commercial gardener's worst nightmare. It is possible that out of 1,000 seed seedlings, 500 will produce small and thick-skinned fruits, and the other 500 will be late-flowering and perish in spring frosts. This situation is unpredictable.

In grafting and crown replacement, you use cloned and tested cultivars. Cornell University emphasizes that the purpose of grafting is to replace a weak variety with a superior and well-known variety. This means that 100% of the trees in your garden will be homogeneous, uniform and predictable. The trees resulting from grafting are exact copies of the characteristics of the mother tree.

4) Modifying the crown structure without destroying the garden

· Crown density: maintaining the volume and structure of the existing crown, which starts photosynthesis from the first day.

· Height Management: Unlike new seedlings that require years of shaping, you can control the tree's growth by choosing a rootstock and grafting method. Massey University's research shows that transplanted rootstocks can improve the length of the branches and the architecture of the crown.

· Resistance to stress: the roots of old trees are the biggest asset of the garden. These roots are more resistant to drought and soil pests than the small roots of newly planted seedlings.

5) Quantitative and qualitative superiority at the same time

Comparative studies have shown that grafted plants often have better performance than seed plants. A research in Spain on papaya plant proved that grafted plants had 7% increase in total yield and 4% increase in commercial yield compared to seed samples. Also, the root system in grafted plants was more developed and had more root density.

Although some forestry research (such as a 10-year study on acacia) shows that in the long term, the seedbed may grow larger in diameter, but for the economic gardener who is looking for fruit quality and early yield, the equation changes in favor of grafting.

Conclusion: saving capital by preserving the roots

Crowning of old trees by grafting is not an alternative but a smart garden management strategy. By doing this, you protect the efforts of the past years to grow roots and trunks and add the latest achievements to your garden in the shortest possible time. In the modern agricultural world, time is equal to money, and crown grafting brings the most precious commodity, "time", to the gardener.
