PLEASE SUBSCRIBE if you are wanting to know more on gardening in Canada & gardening in Colder Climates in general. My methods apply to the USDA Plant Hardiness Zone 1 - Zone 6. As a soil scientist I always try to incorporate science into my videos. Soil science can be over complicated so allow me to guide you.

Ashley is an agronomist who has had a passion for plants since she was a small child. In the long summers as a child, she would garden alongside her grandmother and it was then that she realized her love for greenery. With years of great studying, Ashley had begun her post-secondary education at the University of Saskatchewan.
At first, her second love, animals, was the career path she chose but while doing her undergrad she realized that her education would take her elsewhere. And with that, four years later she graduated from the University of Saskatchewan with a bachelor’s degree in science and a major in Soil Science.
Some of Ashley’s interests are KZread, in which she posts informative videos about plants and gardening. The focus of Ashley’s KZread channel is to bring science to gardening in a way that is informative but also helpful to others learning to garden. She also talks about the importance of having your own garden and the joys of gardening indoors. Ashley continues to study plants in her free time and hopes to expand her KZread channel as well as her reach to up and coming gardeners.

I always bought new potting soil mix every year. Been putting it in same pile for 20+ years. This year decided to reuse. Dug lots out of pile. Been under old oak tree and had lots of organic materials. Old decayed plants and tree roots, even some native soil for microbes. Ran through 3/4 inch mesh, then 1/2 inch mesh. Great consistency. Ended up with about twice your swimming pool. To this I added 4 bags composed cow manure, 30 pound bag of worm castings , blood meal, bone meal and azomite. This took some time to do but mixture looks great!

I'm definitely glad to be reusing potting soil, although I did put my Monstera Adansonii, the pot and the soil in the garbage on your advice because of what I was pretty sure was powdery mildew. Other than that, I've always mixed it in with new or at least put it outside in a garden area to let nature reclaim it.

I read from a soil bag that they advise soil to be replaced early in a greenhouse... That sounded very much like a marketing ploy💸 I have a container balcony garden and I had smelly soil in them. I emptied the soil of each smelly container to a bucket and mixed it many times a day to add air in let it dry in the sun. Then added dry peat and then it smelled like a normal soil. I added horse manure pellets, worm castings and organic slow release fertilizer. I actually even reused houseplant soil in the balcony containers and I think the soil mixes made for indoor plants aren't too bad for outdoor plants either... I always felt really dumb for throwing out "used" soil, and it turns out it was!
Great video- sooo helpful!

The best gardening tool I have ever bought is an insulated hot composter. I have a Juraform JK270. I dump everything organic into it, even leaves and plants with powdery mildew along with kitchen waste including meat and diary. I also throw any pots of soil which may have gone anaerobic from overwatering. Key to using the Juraform composters is to also add wood pellets which helps to aerate the compost as well as adding carbon. I buy bags of cat litter wood pellets from the pet store. The quality and speed of making home made compost is amazing. This was a huge game changer for me. Having your own supply of home made compost should be the first objective of being a gardener. Making compost becomes a hobby in itself.

I have my potting soil recipe for succulents over at gardeningincanada.net
Pure peat moss is also hydrophobic, but with regards to hydrophobicity there is a simple cure. You know when you open that fresh bag of Pro-Mix, and it soaks up water like a sponge? Only to have water go shooting through the pot when you're watering it 6-8 weeks later? That's because potting mixes have surfactants (wetting agents) added to them, and they only last about 6-8 weeks (your mileage may vary). I'm not going to name any companies, but you have several choices of organic (yucca extract) or inorganic (chemical soaps) surfactants that will refresh your soil's ability to absorb, and evenly distribute, water. With Yucca extract I use a pinch (1/16th tsp) in 20L of water, so a little goes a long way. People also use it for foliar feeding, but I don't foliar feed my plants so I stick to the root drench application. This is also really helpful to add to your fertilizer feeding if you use water soluble fertilizers to ensure an even distribution of fertilizer to reduce heavy concentrations of salts in hot spots.
I use the same Kidde pool to mix soil for my 5 gallon bucket garden. That size pool will hold about 20 buckets of soil. I make 10 buckets at a time in mine. I found a big yard cart and I put new wheels on it and I found a plastic bread rack/flat that fits on top of the cart. The bread rack has one inch holes in it. When a plant is done I dump the bucket on the rack and break up the soil ball and sift the soil and let the soil fall into the cart. The greenery and roots go in the compost pile or the trash can depending on what it is. I mix it up and add one bucket of pearlite and one bucket of rabbit manure to 10 buckets of soil. The soil is half chicken coop soil and half well rotted wood chips. Then I add fertilizer, blood and bone meal or fish meal depending on the plant. I don't really know what I doing just going by my gut. Any suggestions? John Davis

@@GardeningInCanada thank you! I won’t add a whole lot from the compost bin just enough to keep enough organic matter for the worms to feast on all while adding some microbes from the halfway composted material. It’ll be blended in and I will keep an eye out for temperature. So excited for your channel, Houston’s nextdoor gardening groups are very active and always bouncing information back and forth. Can’t wait to share your channel with them all.
Ok, another question... can you presoak your composted manure and add it to soil? If it will inhibit proper water penetration into the soil layers, does that mean top dressing garden beds with compost, or planting directly into compost is ineffective? Sorry, I should have curbed all my questions and comments until the end of the presentation 😥
@GardeningInCanada

Presoaking/wetting & rewetting is very important. Best practice is too wet the surface and then dig down to see what is going on water infiltration wise.
My cat insisted on doing a soil experiment with my planting soil, so I had two containers with the same mix, one that i kept away from the cat, and the other was used as a litterbox. The non-fertilized mix still have an amazing quality and a good color, and the cat-fertilized mix is just plain grey now. It definitely cooked the soil and looks like factory-farm dirt, and it hasn't even been planted in. Now to figure out what part of the yard to put it in, after scooping it out.

Hi Ashley, what do you think about people 'flushing' their potting soil? 'Flushing' is deliberately overwatering potting soil to supposedly wash away built up salts. Essentially, you just water the soil until a significant amount of water drains out through the bottom of the pot. Is this something that you think is necessary? If so, any tips on how to do this?... and how often to do this?...
