Gritty mix watering questions

snapksApril 4, 2013

I am slowly repotting my houseplants into gritty mix and trying to figure out when to water is challenging.

So far, I have repotted a...

1) ZZ Plant into a clay pot. It was repotted about a week ago. The color looks okay, but it is rather droopy.

2) Sansevieria in a plastic pot

3) Jade in clay pot(s) - actually started as one Jade plant, but when I went to repot, I found the pot actually held about 9 jade plants. So when repotting, I separated them into 4 different pots, some containing just one jade, while others have multiples. All of them had nearly non-existent roots when I took them out of the nursery pot, so I am hoping that they eventually thrive in the gritty mix. Right now they look okay. They were pretty floppy at first but seem to be firming up.

So - if you are familiar with these plants and caring for them in the gritty mix, can you tell me how often you water? Also, given that the jades hardly have roots, do I need to water them differently? It doesn't seem to make sense to wait until the bottom of the pot is dry, since the roots are in the top 1/4th of the mix.

Also, I have Foliage Pro but have not fertilized any of them yet. How long do I wait after each repot before fertilizing?

Thanks for any help you can offer. My next repot will be my Calamondin tree, which I am probably the most invested in keeping well. :)

I water most of my Jades once a week, and I lightly fertilize every month (if not more often). When plants are establishing, it is beneficial to keep the gritty mix slightly more moist than usual...this is because those roots are in the upper layers, which you mentioned. Wait two weeks after re-potting to begin a light fertilization. And remember, if all the plants are in gritty mix, you truly can water them on a schedule, i.e. all at once. Sure, some will still have moisture, but a watering won't cause them to rot if the drainage and aeration are good.

I have a Sansevieria in a small plastic pot of gritty mix, and I water frequently. With that one, I just heft the pot and water when it feels light.

So is it pretty much impossible to overwater in gritty mix?

Also - will a water-loving plant (one native to swampy regions) actually languish due to the well-drained nature of gritty mix?
