About Seeds and Other Products
What are the differences between treated, untreated, organic and other types of seed?Raw - Seed in its “raw” form, comes in from the parent plant, is clean and has not been treated using any chemical, biological, or physical method.
Treated - Seed has been treated in an appropriate manner to protect it from specific seed- or soil-borne pathogens and thus improve its performance. The treatment may be hot water, chemical, or biological, depending on the pathogen involved. Treatment is applied under controlled conditions, in a commonly recognized fashion, at the manufacturer’s recommended rate.
Standard treated seed is treated using one of several industry-standard methods, which may use chemical, biological, or hot water processes.
Insect Guard treated corn seed is treated with Cruiser to help reduce damage from flea beetles, wireworm, seed corn maggot, and secondary pests.
FarMore® treated pumpkin, squash, and melon seed provides broad-spectrum protection against soil-borne disease, as well as early season protection against striped cucumber beetles.
Untreated - Seed is clean and has not been treated using any chemical, biological, or physical method. Seed crop was not grown under Certified Organic Conditions. Certified Organic Growers: Untreated seed may be allowed in Certified Organic production, provided that a comparable variety is not available in Certified Organic seed. Check with your certifying agency for approval. Pellet ingredients for pelleted untreated seed (product numbers ending in 11-02) are not approved for use in Certified Organic production.
Organic - Seed is clean and untreated, and it was grown under Certified Organic conditions. Allowed for use in Certified Organic production. Pellet ingredients for pelleted organic seed (product numbers ending in 11-03) are NOP approved for use in Certified Organic production.
Filmcoat - Seed has been coated with an inert, food-grade material for easier handling and flowability. When treated seed is filmcoated, the filmcoat helps the treatment adhere to the seed. Certified Organic Growers: Filmcoat ingredients are not OMRI Listed.
Pelleted - Seed has been coated with an inert material in order to increase the seed size for easier planting. Certified Organic Growers: Pellet ingredients are not OMRI Listed. Pellet ingredients for pelleted untreated seed (product numbers ending in 11-02) are not approved for use in Certified Organic production. Pellet ingredients for pelleted organic seed (product numbers ending in 11-03) are NOP approved for use in Certified Organic production.
Primed - Seed has been primed for easier germination, through a physical processes like steam treatment or through chemical treatment. Certified Organic Growers: Priming processes vary by seed type and supplier. Contact us for more information, and check with your certifier for guidance on using primed seed.
Detailed - Fibrous “tails” have been removed from seeds for easier handling and flowability. This may be achieved through either a physical or chemical process. Certified Organic Growers: Detailing processes vary by seed type and supplier. Contact us for more information, and check with your certifier for guidance on using detailed seed.
Does Harris Seeds sell genetically modified (GMO) seeds?
All of our seed offerings have been developed through traditional breeding techniques.
How many seeds in a pound, for those seeds that are sold by weight?
This varies with different items. See each species page for weight to seed count conversion.
How many seeds does it take to plant an acre?
You can calculate your population per acre by taking 6,272,640 (number of square inches in an acre) and dividing by the number of inches between the rows (36), then dividing again by the number of inches within the row (9). 6,272,640 ÷ 36 = 174,240 and 174,240 ÷ 9 = 19,360 seeds per acre.
How should I store my seeds?
To store seeds properly, put the seeds in a plastic or metal container along with a silica gel pack to help absorb any moisture. Store the container in a cool, dry area of your home. Do not store in a refrigerator, due to the high moisture environment they create.
My seed package was left outside in freezing temperatures. Will my seed be damaged?
As long as the seed did not get wet, the freezing temperatures will not hurt the seed.
Can I start my seeds in a window?
Although some have been successful, it is risky to use this technique due to light and temperature issues. Seedlings on a window sill will stretch and grow unevenly. For best germination, it is important to provide even lighting directly above the seedling tray. The use of a light stand is recommended. Uneven and fluctuating air temperatures can also cause poor and uneven germination. Providing even warmth in the soil can be accomplished by using heat mats or cables for bottom heat.
The seed packet states either light (L) or dark (D) is needed. What does this mean?
If your packet specifies light (L) for germination, you can still cover your seed very lightly with some vermiculite to help with moisture retention, but make sure that enough light shows through to the seed to initiate germination. Other species of seed germinate better in a dark (D) environment, with little to no light. In those cases, using a coarse vermiculate or a good seed starting mix to cover your seedling trays not only helps to exclude light, it also helps retain moisture.
What does the number of days listed for a variety mean? (ex. Gladiator Pumpkin…115 Days)
For species that are normally direct seeded such as vine crops, sweet corn, peas and beans, the maturity is figured from the time the seed is planted in the garden or field. For species that are normally started as a seedling first and then transplanted such as tomatoes, peppers and eggplant, the maturity is figured from the time the seedlings are transplanted to the garden or field. Note: the number of days is figured for our growing conditions here in NY. The farther south you are, the quicker varieties will mature due to a higher number of heat units.
Why do some varieties become back ordered or out of stock?
Just as you have to work with nature in producing a crop of vegetables or flowers, our seed suppliers have to work with nature to produce a crop of viable seeds. Sometimes there's just not enough seed from a given crop to meet the demand. Harris sells only seeds that meet the highest criteria. We place multiple orders for seed throughout the growing year. At times you may have to wait for a fresh seed crop to be harvested before we can provide the seed to you. Sometimes there is an unprecedented demand for varieties that address disease or climactic conditions. In those cases, demand may simply exceed supply. Our suggestion for ensuring that you receive the varieties that you prefer: order as soon as possible after you receive our catalogs.
Why has Harris Seeds stopped carrying my favorite variety (vegetable or flower)?
Unfortunately, each year our suppliers discontinue producing varieties that have been staples with our customers for many years. Breeding programs are producing new products at an unbelievable rate now and many older varieties are being replaced by the newer ones. Please call anytime you no longer see a favorite variety listed. We will be happy to recommend a suitable substitute.
