Dividing Dormant Dewthread Sundews (Drosera tracyi)

Jason from Arizona asks about dividing his Drosera tracyi (commonly called Dewthreads) after it formed a beautiful bush and entered dormancy with at least eight visible resting buds (hibernacula).

Expert Advice: Yes, Divide During Dormancy

Jeff Dallas of Sarracenia Northwest confirms that Dewthreads respond very well to division of their dormant hibernacula. During dormancy, these plants have minimal roots and will grow new ones upon emerging in spring. Historically, Dewthreads were propagated almost exclusively through hibernacula division, and this method works equally well for D. tracyi, D. filiformis 'Florida Giant', D. filiformis, and the hybrid D. × hybrida.

Timing Is Key

Just like with Sarracenia, it's best to wait until late winter to divide. In warmer climates like Arizona, "late winter" arrives much earlier than in the Pacific Northwest. Dividing at the right time ensures the plants have the best chance to establish new roots before the growing season begins.

Good Growing!
