Compost 101 and Potatoes 102

Spring 2019

Free hands on gardening classes
Sat 04/20/2019 at 10 a.m.
Composting 101 & Potatoes 102


Harvest and Create Compost 101

We will harvest last years compost and use it to enrich this years garden beds. We will create a new pile of compost. Please bring compostable materials if you have them, especially greens. An easy way to keep greens thru the winter is in a bag in the freezer.

The class is hands-on, bring gloves, materials to compost, and dress to get dirty!

Potatoes 102

The snow last weekend let us plant potatoes in containers. Weather permitting, we will plant them in the ground this Sat 4/20/19 at 10 am.

NOTE: Citrus 2019

We were unable to get citrus from the last grower mentioned. We have found a houseplant grower that does supply citrus and we will get you an up to date list. Thanks for your patience.

Weed Killer

Get a jump start on weeds as you are prepping your soil and planting your first crops. We carry both horticultural vinegar and citrus oil based herbicides.

Green Gobbler Omri-Listed 20% Horticulture Vinegar Weed Killer

Green Gobbler’s 20% OMRI-Listed Vinegar Herbicide/Weed Killer is a non-selective bio herbicide that packs a punch. Use it to kill all types of weeds, including dandelions, crabgrass and other annual and perennial weeds. Our vinegar is certified for organic use by OMRI, because it is derived directly from corn. It contains no harmful chemicals and degrades promptly in the soil.

Omri-Listed Avenger Weed Killer

Avenger Weed Killer is a non-selective, post-emergent organic herbicide that safely kills weeds, grasses and broadleaves. Unlike other organic herbicides that just burn foliage, the active ingredient in Avenger, d-limonene (citrus oil), naturally strips away the waxy plant cuticle causing dehydration and plant death. University and independent testing results prove that AvengerĀ® Weed Killer is as effective yet even faster acting when compared to the leading synthetic herbicides.

We are continuing to maintain our soil pH, add organic matter, and living organisms when planting and transplanting.

Back To Earth Acidified Composted Cotton Burrs

Back To Earth Acidified Composted Cotton Burrs is an ideal general-purpose mulch for amending clay or sandy soils. This product is available with elemental sulfur to help neutralize high pH soils. Soils low in organic matter and humus or with poor tilth and structure cannot be rejuvenated with chemical fertilizers. Back To Earth compost can quickly start improvement of such soils, since it begins to function immediately, restoring vital organic matter and humus to soils, regardless of soil conditions.

Black Gold Soil Conditioner

When it comes to buying a garden amendment, product quality is the name of the game. And the key to product quality is the choice of raw materials used to make the garden amendment. Take the popular Black GoldĀ® Soil Conditioner; it is manufactured using only the highest quality raw ingredients. The product may include a combination of these raw materials: aged/composted bark, Canadian sphagnum peat moss, compost, bat guano, earthworm castings and a proprietary blend of mycorrhizae.

Acidified Composted Cotton Burrs

Potatoes prefer to grow in acidic, light soil. We have found Acidified Cotton Burrs to be the perfect soil amendment for potatoes and the entire garden.

Soil Sulfur

pH has to be maintained throughout the growing season. We fight both alkaline soils and alkaline water, so this is a product that we use a lot in our own garden. We carry garden sulfur in 4# and 50# bags.

GrowHands Salt Scrub

Gardening can be rough on your hands and body. We carry an all natural hand scrub, made right here in Rifle, to use at the end of a long day gardening.

Mom’s Magic Balm

Speaking of a long day in the garden, I use Mom’s Magic Balms on my hands and feet every night. It has really helped with some problems I have with my hands. Not only is it effective, it is made right here in Glenwood Springs.
