Ipomoea lobata problems — and how to fix them
Ipomoea lobata (Ipomoea lobata) 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.
Slow start in cool springs
It is heat-loving and resents cold; growth and flowering stall in cool weather. Start seed indoors and plant out only after soil warms.
Sparse flowering in shade
Inadequate sun reduces the colourful spikes. Site in full sun for the full red-to-cream colour show.
Hard-seed germination delay
Like its relatives, the seed coat is tough. Scarify and soak overnight before sowing for even germination.
Aphids on soft growth
Aphids cluster on tender shoots and buds. Hose them off or use insecticidal soap to protect new flower spikes.
