I have:
Crassula muscosa
Sedum morganianum
Crassula Ovato Gollum
Senecio Jacobsenii
Crassula Marginalis
Senecio radicans
Sedum rubrotinctum
Schlumbergera Bridgesii
Echeveria coccinea


Thank you!

I don't grow a lot of these, but my echeveria and crassula I wouldn't hesitate to repot again, given that situation.

Awesome! Having a specific list of plants is so helpful.

Completely agree with ez for the Echeveria and Crassula - you have a lot more to gain from a better soil like gritty mix than a bit of additional stress on the plants.

For the Sedums, just be careful when you repot. S. morganianum can be pretty fragile but will grow back. Any leaves that fall off your S. rubrotinctum can be easily propagated by laying them on top of gritty mix.

I'm going to assume that Senecio radicans is similar - people have mentioned using a bent paper clip to hold similar plants down, if they don't stay put in the gritty mix before the roots get re-established.

Schlumbergera bridgesii will not do well in gritty mix, it's an epiphyte / tropical cactus. Normally grows on other trees in the jungle. Some people are growing them very well in just fir bark fines (same stuff as for gritty mix). Bark is very expensive in Canada, so I'm growing my Schlumbergera truncata and buckleyi using a mix of large perlite and granite grit. Rina suggested this mix to me and it's working quite well!

Thank you so much!

Is it ok to repot, even though I recently repotted?

I'll keep the Schlumbergera bridgesii where it is for now since it doesn't seem to be having any problems and is growing nicely.

Love the bent paper clip idea! Thanks!

The Senecio radicans have taken off in cactus mix/perlite and were a pain to pot (I'm sure the paper clip will help, though), but I imagine they'll do so much better in the gritty!

We posted at the same time, hehe. Yes, do it! It's not a problem. Watering with gritty mix is really different, but I'm sure you'll get it. =)

Oh, forgot to answer your other questions:

1. Two weeks after repotting, fertilize with 1/4 strength weekly.

2. I have a digital water meter, it works quite well in gritty mix. It is much better used as an indicator of "maybe I should think about watering", rather than "yes I need to water now". There are many technologies for sensors, so your results may be different than mine.

Still need to look at each plant to evaluate if it needs water, how much, and when. Unglazed terra cotta pots are great, since when you can touch them you can tell how much moisture is in the pot. Of course, if it's SUPER hot where you live or you want to water less frequently, it may not be the best choice.

Here is my last week in gritty mix. Plants kept outside, I watered twice:

Which water meter do you use in gritty mix?

I'm using the Parrot Flower Power. The app and interface is very cheesy, but it's a well designed meter that measures the right things. Moisture is measured 0-50%, light in PAR DLI, temperature -5 to 55C, and fertilizer in ms/cm. Fertilizer measurements are totally useless in gritty mix, but works well in soil mixes.

It seems expensive for ~$70, but moisture meters are ~$30 and light meters are ~$100+. Data is logged every 15 minutes and its watering recommendations are surprisingly accurate (water in 2 days, water today, etc.).

Based on my experience, the usefulness of a moisture meter depends on what you are growing. For plants like Crassula, Echeveria, Gasteria, and Haworthia, it works very well. For very specific plants like Mesembs, it is not useful whatsoever.
