Ipomoea. Start seeds 4-5 weeks before transplanting
outdoors. Soak seed for 48 hours in a wet paper
towel or nick seed coat with a knife to speed up
germination. Use 3″ or larger pots with a good soil
substitute like Berger BM-2. Place seed 1/4″ deep,
2-3 per pot. Germinate at 70°F. After emergence, insert
a small bamboo stake into pot to keep seedlings
from becoming entangled. Plant outdoors in early
summer. Seeds may also be sown outdoors after
soil has warmed up to about 70°F.
NOTE organic growers: Morning Glory, Moonflower or
sweet potato vines work as a squash bug deterrent.
Plant one of the 3 plants in between 2 or 3 squash or
pumpkin plants. Squash bugs hate this family of plants.
