Plant Care
-
Once you’ve placed an order, we ensure your plants are true to name. Prior to being placed in cold storage our rootstocks are carefully hand sorted to the highest grading standards in the industry. The conditions under which TRECO® stores, handles and ships your rootstock order helps to eliminate the potential problems that may occur with root dryness and heat or freeze damage to the tender rootstock tissues.
-
Before our rootstocks reach you, you must first be ready for them. Preparing the soil is an important first step. After a site has been chosen, cover crops should be used to help build up the soil at least one year in preparation prior to planting. This should allow ample time to determine soil nutrient composition and also provide sufficient time for correcting deficiencies.
While proper nutrient levels are being established, steps should also be taken to eliminate all nematodes and other potentially destructive diseases and pests. Since soil and growing conditions vary widely, no one system can be considered best in all cases. Regardless of local conditions, fumigation and sterilization of soil are vitally important. Typically Methyl Bromide and Chloropicrin are the most common fumigants used. They are effective particularly when used in combination with other agents that may be warranted by your specific soil conditions. To determine your specific needs it is best to consult with local soil specialists.
When desired by customers, rootstocks are transported by refrigerated trucks in safe reinforced containers. Make sure soil is well aerated after fumigation and before planting!
-
Before planting your rootstocks it is highly recommended that you trim back the roots to within 1/2” to 3/4” of the rootstock shank. This will help promote new root growth.
Planting Your Rootstocks
After your soil has been worked up and you have planted the rootstocks, be sure to pack the soil around roots carefully avoiding gaps between soil and rootstock so the roots don’t dry out. Finally, keep a careful eye on moisture levels throughout the first growing year. Maintaining proper water levels is absolutely essential to ensure optimum tree growth and health.
A Word of Warning in Handling Rootstocks!
Ethylene gas concentration will cause extensive damage or kill your rootstock or trees if stored with apples or in a storage room that has not been completely ventilated. Cedar tow shavings normally packed around tree roots for shipping should not be used for prolonged packing or extended storing of rootstocks as they can cause damage to the root.
Virus Certified
It’s our comprehensive root care system that ensures the virus-tested quality of our rootstocks. Before 1930, few of the viruses that affect deciduous fruit trees were known. Since then, over 50 viruses and virus-like diseases caused by mycoplasms have been discovered and isolated. Some of these viruses and mycoplasms can infect and kill a mature tree in one or two years!...wiping out years of work and considerable expense.
To ensure a healthy orchard, it is important to choose healthy, virus certified rootstocks.
For more than forty years, TRECO® has utilized the most advanced scientific research, carefully controlled growing conditions and the most efficient cultivation techniques to produce virus certified rootstocks of the very highest quality. As a result, our rootstocks are produced according to the rules and qualify for the Oregon Certified Nursery Stock tag, and are sold as a product of this program.
Oregon State Department of agriculture: PRO-TECH Program
At TRECO®, our annual certification by the Oregon State Department of Agriculture, involving visual inspections and tests during the growing season, is part of our commitment to excellence. We register each rootstock variety with the state and periodically re-index to maintain virus-tested certification.
Our PRO-TECH system is a comprehensive root care program that guarantees our rootstocks meet the highest standards, supported by a 2% fee from each sale for ongoing research. We're at the forefront of combating orchard industry diseases, utilizing certification programs and new virus detection techniques to provide rootstock that is free of known viruses, ensuring our customers receive the best possible product.
How we monitor for viruses
Monitoring by visual inspection, together with specific field and laboratory testing, is another crucial step. Laboratory tests have improved tremendously in the past decade as new molecular diagnostic techniques have been developed. These new molecular techniques, including PCR and deep sequencing, are used to verify initial mother plants (or G1 material) are free of all known viruses. Cuttings from these mother plants, once established, become G2 plants within the nursery and become the basis for all certified plants produced within the nursery. G2 plants are tested for canary viruses, common viruses that can be pollen or otherwise carried into certified blocks.
The most cost-effective test for these canary viruses in a nursery’s certified blocks remains the enzyme-linked immunosorbent assay (ELISA) test. This test can quickly and accurately detect canary viruses in infected plants in as little as two days and meets the international phytosanitary certification standards of Canada and other states.

-
Avoid late planting or planting in very hot conditions which could induce sun-scalding. Plants should be conditioned when removed from cold storage at a milder temperature for at least two weeks prior to planting. In some extreme cases it may be necessary to whitewash the trunks in order to avoid sun-scald. Fumigated ground should be allowed sufficient time between fuming and planting. Make sure all fumigant is out of the soil.
