Fascination with Pro Mix... no more

Prompted by Kevin's Pro Mix price thread, I thought I'd start a new one to talk about a topic related to Pro Mix. A lot of fig growers love it and use it a lot. I don't anymore. If you feel the same, tell me why. If you like it, that's cool too. Let me know what you like about it compared to other substrates you tried.

Me, I stopped using it for the most part. My first year rooting fig cuttings was a 100% success. I simply stuck the cuttings in my garden potting mix that I use to grow vegetables and kept the soil lightly watered.

The next year, after reading and watching numerous instructional videos on rooting figs, I quickly learned that Pro Mix was the IT substrate to use for fig rooting. The best! There was none other like it. Man, have I been doing this all wrong? :unsure: So, I followed the trend. I had a pretty good success rate, about 85-90%, but found it to be a pain in the rear as far as maintenance. I had to water my Pro Mix very carefully every other day, sometimes daily. I had to weigh the pots to avoid over-watering. It worked!

Last fall, I decided to root a few cuttings, but I followed the newest, 'bestest' method preached by one of the well-known youtuber fig growing 'gurus' and vouched for by some fig growers on the forums. It's pretty much the same method, but I'd have to put the fig tree pots inside plastic bags. Finally, THE solution to make my rooting easy! ... How didn't I think about that myself? That turned out to be a freaking disaster for me. Zero success rate. Abysmal failure. No roots for a while, followed by root rot. Lost several very good cuttings I was so looking forward to trying this next growing season... alas, that's not gonna happen.

I am an experienced gardener with many years of growing plants from seeds, and I have a 4-season experience rooting fig cuttings. My verdict - I don't like Pro Mix. I can make it work, not in plastic bags, but it's a pain. Why use it, then? Why pay a premium price for it? I don't see a good reason.

I've had a much better success with good old garden potting mix that I buy in bulk from a local supplier. Success rate - 100%. I water them pots every few days. Sometimes, I forget to water and do it 1-3 days too late, but that's never a problem because the substrate is pretty water-retentive, and it takes a while for it to get bone dry and damage gentle roots. I find it quite forgiving. It works. It works very well for me. I don't need no Pro Mix. I grow all my figs in this mix, from rooting on. No, it doesn't get waterlogged. No, it doesn't cause root rot. No, it doesn't get too heavy. Yes, it works. It's natural. I have worms and all sorts of bugs and microscopic life in it. My figs love it.

I hope some new growers will find my experience helpful and insightful. IMHO, you don't need to follow trends, YouTubers, and those so-called fig 'gurus'. Find your own way. There are tons of ways to root a cutting. The simplest ways work best, IMHO. That's how nature works. Stick a cutting in real soil, give it a bit of water, and it will grow just fine. Works for me. This spring, I put down a thin layer of vermiculite in my rooting pots. That keeps moisture in, gnats out, and prevents green algae from growing on the surface.

Here are my cuttings that I started rooting on Jan 1, 2025. Tree pots, garden potting soil I brought into the garage in the fall to keep it from freezing, a thin layer of vermiculite on top of the soil, watering every 4-5 days, and lights from day one.

@TorontoJoe You might be excited about this one :) I didn't realize I was rooting one TP among other of my cuttings. Crazy vigor.

I have never understood the fascination with Pro-Mix. It’s just peat moss with perlite and other additives. You can easily get a comparable product locally or make your own for less money. When I first started with figs, I specially ordered a bale because PM isn’t sold locally to me and it’s recommended so much. I had the most fails with it. Other people have fails with it all the time too, but yet it continues to be the rooting mix of choice. Whatever… I give up trying to understand people anymore, lol.
 
When you say "I didn't realize I was rooting one"
You are truly a FigFanatic. :)
As far as the Promix. I have only bought there peat.
I can not bring myself to buy any of there mixes.
You maybe quite right. :) I had a bunch of cuttings left over in my fridge, so I rooted them all instead of seeing them deteriorate or throwing them out.

I wish my thumbs were as green as yours.🤣 I too used PM because I was told it was “The One” to use. This year I only bought 2 cuttings from OTBPN. And I put them directly into the ground in the back yard, covered the tops with mulch then a plastic pot with bricks on top to keep the pots from blowing off from the wind. I’ll find out come spring if they rooted.
 
Im not sponsored by Promix ( I wish ), but been using Promix HP for years, and its my go to, the easiest and most successful ( not just rooting, but healthy big growth )

I think you can improve your method, and you will be satisfied. The biggest challenge I see with using Promix, is that folks dont let the Promix set for enough time before rooting, where it seem moist but quickly absorb and lock all the moisture, in this case you want to make sure your mix is moist first time, then let it set overnight and then again add more water until it holds enough water where it feels heavy but will not drip when you squeeze it.

I started doing the method below in 2020, it was posted on Ourfigs back then, and later made its way to different youtube channels, very easy to do and almost maintenance free. Trees below are 8 weeks old and I have over %95 success rate ( young plants not just rooted)

Good luck! I hope they both root well. I'd be a little careful with 'outside' rooting as the weather can be quite unpredictable, but indoors I am quite comfortable with the 'stick it in soil and don't worry about it too much' approach.

Glad it works for you.
 
Most of the videos and all that you see instructing people on Figpops are directed specifically to new green beginners. And with that instruction the teacher needs to be able to list the materials used, so Promix products being a very widely distributed product that carries a great reputation for quality and consistency is generally the medium used. Promix markets 12 individual blends in their commercial application catalog, one of may carry the amount of moisture you are looking for verse what you have tried in the past.
You are also coming at the task of rooting figs from a lot of experience as you state. You have a good idea of what to do and you know the resources of your area. Not everyone has a supplier nearby blending good quality potting mix.
I second the remark on the need to mix your water in the day before use, in order to get the critical amount of moisture needed.
I'm also right there with you on the sentiment of finding what works for yourself and perfecting that magic of time.

A wise old man told me this a long time ago.
"I've done so much, for so long, with so little. I can do almost anything with nothing. But it's nice to have the fancy poop. "
 
Not everyone has magical garden soil. It usually holds too much moisture and is full of fungus gnat eggs and other things that once brought indoors proliferate in the ideal growing conditions. Here are some that were started beginning of December, they have been up potted into 5x12 pots

We have never used promix and it seems pretty over priced. But definitely convenient.
Ultimately straight coarse sand is the best it’s just very heavy. If you want to know about potting soil watch Gary matsuoka of Laguna hills nursery on potting soil. We have rooted cuttings in everything from straight peat to sawdust to age bark. It’s all about moisture control not the mix. We recently heard about a study of rooting media and rockwool ended up the winner.
 
The reason I like it is pretty straightforward... and I should say that I'm no more married to it than Promix BX or Sunshine #4. As far as I'm concerned the triple mix I get in bulk from my local peasano garden centre is excellent soil for growing most things. That includes fig trees. Every bit as good or maybe better given that it's a living soil.

So, why do I pay so much for one of the gritty mixes? I'm reminded every spring and fall when I need to move all the pots out of or into the garage. I use these because they're light. That's pretty much it. I can feel the difference in my back.

All my other container plants and raised beds get bulk triple mix. They don't move much.

Yes, I use it to root cuttings because I have it on hand... and it's pretty easy to regulate the moisture but even on a layer I have no issue using the triple mix

I also find that the promix (or similar) is easy to debug and comes for the most part free of gnats etc... I would never bring bulk triple mix into the house.... especially without baking it.

I guess I can say that I like it a lot, but it's not the only thing I like. I don't really like paying for it.

What I really wish is that I could buy yards of custom blends at a decent price. The triple mix I get for $50 depending on whether I bring some capo and a loaf of bread with me. :)
 
It is something that works well for me, not so much using it to follow a trend.
I have tried many things over the years.
It is what yields me the best results.
I do respect the fact that not everyone likes it.
I think it's cool you found something that works better for you and are sharing that information for others to see more options.

I'm still open to try other soils/substrates, but when I tried garden soil I just had rot and many many failures....and many many gnats.

Your little trees look great and healthy, nice work :)

I would be more than happy with a sand mix.... if someone would come over and move my pots. :)

Very interesting perspective. I appreciate it.

Why not? Been doing it for years and have yet to have any serious concerns.

That would be too much even for someone like me, who doesn't mind moving 15g-20g pots filled with garden potting soil. :D But sand with 3-4 inches of compost on top would be nearly perfect.

I brought in bugs twice. Once was an aphid infestation and the other time scale. It was very difficult for me to eradicate.
