Resources for RCF's Seed Garlic Growers

Submitting Lab Samples

All Rasa Growers are to be familiar with common diseases and pests of garlic. Please familiarize yourself with potential problems by carefully studying our Diseases and Pests of Garlic page.

We take disease prevention seriously and require all our growers to submit samples to plant health laboratories annually.
  • Date to Submit: The idea is to receive test results prior to harvest date. So, submissions should be prepared and mailed 3 to 4 weeks before expected harvest date.
  • Follow instructions below (Submission Guidelines) to prepare your samples.
  • Download the RCF Grower General Submission Form (below) and go to the website link (below) for further details about submissions.
  • The RCF Grower General Submission Form is partially filled out and directs the lab to send test results directly to RCF so that you won't need to remember to forward results. RCF will send all Growers their test results as soon as they are received.

Submission Guidelines
  • Send whole plants and leave whatever dirt is sticking to bulb when you pull it out, but no need to add extra dirt.
  • Send in at least one bulb from each of your cultivars.
  • Package the bulb ends together in a plastic bag and use a rubber-band to hold the bag on. This prevents the tops of the plants from making contact with the bulbs.
  • Bend the tops of the plants however you need to in order to fit the samples into a reasonably sized box.
  • Pay for "Routine," as opposed to "Urgent" or "Casual"
Samples are submitted (or hand delivered) to the following address:
Plant Health Laboratory,
B.C. Ministry of Agriculture
Abbotsford Agriculture Centre,
1767 Angus Campbell Road,
Abbotsford, BC V3G 2M3

Supplies & Equipment

We'll soon add information here about:
  • Dehumidifiers
  • Hand Tools
  • Undercutters (design)
  • Dimplers
In the meanwhile you can call us or contact us by email to ask about these items.

Soil Tests

It's always a good idea to test your soil so that you know precisely what you're starting with and what amendments you need to consider. Below is just one lab to which you can submit soil samples for testing. Be sure to mention that you are growing garlic and they will make recommendations as to how best to amend for that crop.

Cost: $53.50 for basic, $70 for detailed test.

Sorting Tool

Consistently sized bulbs is important at Rasa Creek. To insure uniform sizing across all of our growers we've devised a simple sorting tool for everyone to use.

The RCF Sorting Tool Download a description, with instructions to make your own, here: 

We've made some adjustments to the sorting tool since 2016 and will be supplying new tools for use in 2017. An unacceptable quantity of bulbs were undersized as we approached time to ship orders and we so hole sizes for M and L bulbs has increased slightly to compensate for shrinkage.

Correctly Processing Bulbs

  • Firm bulbs. No soft, dry, discolored, bruised, or exposed cloves.
  • Clean and free from mold, decay, damage, dirt, disease.
  • Roots trimmed to no less than 1/4" and to a maximum of 1/2".
  • Necks trimmed to no less than 1" and to a maximum of 1 1/2".
  • Stem cut should be clean, not ragged.
  • Remove all loose wrappers. Watch for dirt around basal plate.
  • Transport containers should be clean and washed free of dirt and debris.

Delivering Bulbs

We do not accept garlic delivered in onion sacks. You must pack your bulbs in bins. We cannot stack and handle bags as easily as bins. Either buy your own bins or call us to see if you can borrow some from us for delivery.

The best type of bins are 23" x 15" x 9" tulip bins perfect for garlic too. You can get them for instance from the Van Noort Bulb Company in Abbotsford, BC during the Spring only. Call them at 604-850-1688 and reserve your bins at the price of $3.50 each. Must pick up—no shipping available.

Another less preferred but acceptable size (19" x 12" x 8") produce bin can be obtained from Growers Supply Co. with locations across BC.

Label each bin with a tag that clearly states:
  • Your farm name or three-letter acronym assigned to you by us. For example, Rasa Creek Farm is "RCF."
  • Full cultivar name or three-letter acronym assigned to cultivars by us. For example, Creme de la Rasa is "CRM." Acronyms can be obtained from your sales tracker provided by us.
  • The size of the bulbs in the bin. For example, extra large bulbs are labeled "XL." The possible sizes are XXL, XL, L, M, S, XS.
For bonus points color-code your cultivars by attaching a ribbon of the same color to all bins containing a particular cultivar regardless of size.

NOTE: The number of bulbs per bin are not needed by us. We only need the total number of bulbs per cultivar that you're delivering to us. We then use an online spreadsheet to which you'll have access to to keep track of your inventory.

Beard too long Neck too long
These onion sacks do not stack well and
are hard to handle.

Labels do not conform to three-letter
acronyms. Farm name is missing.

Damaged clove
This system is almost acceptable. But
while "Tibetan" is a cultivar name, "Rasa"
is not. Should have been either
labeled "Creme de la Rasa" or "CRM."


RCF Timeline

As per signed agreement:
April 21st—Crop Report: Report of spring emergence with estimated percentage crop loss (if any) and rough count of each variety.

June 15th—Harvest Estimate: Revised rough count of how many plants of each variety will be harvested. Pre-harvest sales begin in early July and RCF will only rely on 50% of the estimated harvest for this purpose.

June 30th—Lab Testing: All growers should send random samples to a qualified lab for testing. Bulb & Stem Nematode and White Rot are the two primary diseases of concern. RCF has posted the procedure for submitting samples on this page (see above).

Aug 28th—Harvest & Sort: As soon as possible after harvest, a rough count of each variety broken down into sizes according to RCF sizing protocols. There are very quick methods for rough sizing during harvest that RCF staff will train growers in using.
Aug 15th—Final Count: RCF online shopping cart opens in mid-Aug and we need as accurate a count as possible in order to populate the inventory levels of our shopping cart items.
Aug 30th—Delivery: As per agreed upon protocols, all garlic to be delivered to facility at Your Local Farmacy in Lumby by this date.
Sept 30th—1st Payment: The bulk of our sales will happen from July thru September and RCF will issue payment to Growers for all garlic sold during this period on September 30th.
Oct 1st—Inv. Assessment: RCF & Your Local Farmacy will confirm remaining inventory for each Grower and make contact to discuss options going forward (e.g. continue with seed sales, explore culinary sales, resume possession of bulbs, etc.) Note: Historically, up to 20% of RCF's sales have taken place during the month of October.
Oct 30th—2nd Payment: This will likely be the final payment of the year and we will again review and discuss options if any stock remains in inventory.
