I have a 'Sunsplash Apricot' that I grew from seed. I am really liking it.
Question is: Is it ok to repot putting it several inches below its current soil level? That is bringing the soil level say 2-3 inches above the exposed stem. I know this is ok with begonias and impatiens. OK with vincas also or would it start rotting?
I want to be sure before I try it. Even though I have rooted cuttings from it I don't want to lose the original.

Kyle-- It is a tender perennial. You should be fine adding soil. I would water it first, then stick it in water (a couple of inches deep) for 2 to 3 hours to get a good thorough soaking of the roots. Finally add the new soil and water again.

Many blessings for a successful gardening season!

Hey, thanks. Yes, I know it is a tender perennial. And I have no watering issues. My question is will it be ok to plant in another pot with the growing point 2-3 inches deeper than it is thus bringing potting soil 2-3 inches above the exposed stem. Thanks.

Yes-- Go ahead. The point I was trying to make was to make sure the root ball is really wet, and evenly wet, and wet after planting. This will aid in the change of the soil adjustment. Another inexpensive aid would be to add a little hydrogen peroxide to the water and water with that.

May you be blessed with success!

As susceptible as Catharanthus is to crown rot/wilt diseases (like Phytophthora), I would be very hesitant to try this. If it were me, I'd prune it back and take a bunch of tip and softwood stem cuttings for insurance. Then I'd give the original plant some half-strength liquid fertilizer. I'd tip prune, if needed, to shape it as it regrows

If it still looked leggy, then I would plant something like Fan Flower (Scaevola) around it. Green Grin!

The apricot varieties of Catharanthus are always my favorite. So pretty! Lovey dubby

Thanks. I do have two other small plants from cuttings. I think I'll do as you suggested and then if the other two do well I'll experiment with the mother.
Thanks, everyone.
