Potatoes Have Rolled In!!


Five Delicious Varieties

… that were all organically grown here in Colorado.  We have selected these varieties because they all grow very successfully here.  Eve hand-delivered the potatoes yesterday come in and check them out!


(Certified ‘seed’ potato) – (heirloom yellow)
German Butterball offers everything you could want in a potato: heirloom quality, deep golden flesh, and a delightfully mild flavor.  Versatile for every kind of preparation.  Best if harvested when small to medium sized. Superior storage.  Approximately 110 days to maturity.


(Certified ‘seed’ potato)
Kennebec is an excellent, widely adapted, medium to late, all-purpose, white potato, bred by the USDA in 1941. This fast-growing variety has high yields of round to oblong tubers with shallow eyes, buff skin and white flesh that maintain good quality in storage. Plants do best when planted at 8-10” spacing to avoid overly-large tubers. The ivory flesh is firm and starchy with minimal water content and offers a rich, earthy and nutty flavor. Excels as a frying potato (fries, hash browns, chips, etc.) and is well suited for baking, mashing or roasting. Kennebec potatoes keep their shape when cooked, perfect for potato salads, curries, soups, stews. Resistant to Potato Virus A and Potato Virus Y; moderate resistance to Potato Virus S, Potato Virus X, blackleg, and foliage late blight.


(Certified ‘seed’ potato)
Red inside and out! Bred in & for Colorado. Excellent as potato chips, French fries, oven fries, and also great for baking, mashing, and potato salads. High in antioxidants!  Early to Mid-season.


(Certified ‘seed’ potato)
Uniform, high-yield, deep purple skin and flesh, very high in anthocyanins (high-potency antioxidant).  Bred in and for Colorado.

RED THUMB Fingerling Potato – NEW!

(Certified ‘seed’ potato)  Early (65+ days)
One of the best tasting of the fingerlings, with unique ruby red skin and marbled deep pink and cream flesh that is waxy, firm, and has a buttery taste. A favorite with chefs for their flavor and beauty, their red coloring holds well when cooked.  Excellent for potato salad, soups, mashing, and for grilling or roasting. Red Thumb is easy to grow and produces high yields of medium-sized, well-clustered, finger-shaped potatoes. The tubers are long-keeping and the vines are very vigorous. Be careful not to overcrowd this variety. Harvest in late summer at 2-3” long. They can be grown in grow-bags or large containers. (Photo credit, right: White Flower Farm.)

Potato Growing Instructions

From our friend, Frank Hodge

Potatoes grow best in full sun.  Plant seed potatoes (pieces of potatoes or small whole potatoes – plant whole if they are smaller than a golf ball) with at least 2 eyes per piece. If you are cutting up the potatoes, do so ahead of time (couple hours to a day prior to planting) to give them a chance to form a protective layer for moisture retention and rot resistance.

Plant as soon as when soil can be easily worked.  Plants will begin to grow when the soil temperature reaches 45 degrees.  Plants can tolerate a light frost but be prepared to cover them if a hard frost is expected.

Spread and mix compost into the bottom of a 4-6” deep planting trench. Soil should be moist, but not water-logged.  Plant seed potatoes 4” deep, 1 foot apart, with the eye side up. Potatoes thrive in LOOSE, well drained soil with consistent moisture.

When plants reach about 6” tall, cover them with light compost or straw until just the top inch or two still shows. Continue to cover the plants (called hilling) as they grow. This will result in a fairly significantly sized mound.  Harvest potatoes on a dry day. Soil should NOT be compacted, so digging should be easy, but be gentle so as not to puncture the tubers.  “New” (small) potatoes may be ready in early July.  Mature potatoes should be harvested 2-3 weeks after the vines die (usually late July / early August). Brush off any soil, and store them in a cool, dry, dark place (but not in the refrigerator).  Do not store potatoes with apples as the ethylene gas produced by the apples can cause your potatoes to spoil. Do not wash potatoes until right before use.

Onions, Leeks, & Shallots, Oh My! 

Don’t worry if you haven’t gotten your onions in yet, we still have a nice stock of Walla Walla and Copra onion starts.

And, we have a wonderful selection of onion, leeks and for the first time, shallot seedlings!  These are specialty varieties for those that don’t want an entire bundle.  Come select your favorites from varieties including Cippolini Genova, Ailsa Craig, Walla Walla, Italian Red Bottle, and Purplette Onions.  Bleu de Solaize and King Richard Leeks.  And, Zebrune Shallots.

Weekend Classes

Our classroom will be overflowing this weekend with an amazing collection of THREE CLASSES!   Alison Peck kicks us off on Saturday at 10 AM with her much-loved Edible Landscaping class, showing you how to artfully incorporate food plants into your garden.  Then at 1 PM Katie McAllister (another Matrix Gardens’ guru!) shares What to do about the Japanese Beeltle Invasion.  (None of us want to think about those nasties this early in the season – but now is the best time get informed and prepared!)

On Sunday at 1 PM, Mikl wraps up the weekend sharing great info on Organic Lawn Care – you don’t have to use chemicals to attain a lush, green turf!

Veggies in the House!

In addition to tomato starts, we have a beautiful bounty of cool-season veggies, which can be planted after a few days of hardening-off or under row cover fabric. We have two weights of row cover. The lightest one is Seed Guard and it can be laid directly over seeds, giving 3 degrees additional protection, and shielding them from critters. Ensulate is the heavier weight product and it can last many years.
