Annual baby's breath problems — and how to fix them
Annual baby's breath (Gypsophila elegans) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and stem rot in heavy or wet soil
Fusarium and Pythium root rots rapidly kill plants in poorly drained or compacted soil. This is the most common cause of failure with Gypsophila. Improve drainage before sowing; never sow into waterlogged ground. Succession sowings in light, gritty soil side-step the issue.
Short, single-flush blooming period
Individual sowings flower for only 4–6 weeks before going to seed and declining. This is a feature of the species, not a problem per se, but gardeners expecting prolonged summer colour are often surprised. Resolve by making succession sowings every 3–4 weeks from early spring to early summer.
Aphids on shoot tips
Soft colonies of green aphids colonise actively growing tips and reduce vigour. Knock off with water jets or apply insecticidal soap spray. Natural predators usually control populations within a week or two. Heavily infested tips should be pinched out.
