Violas, stocks, calendulas, and primroses should be planted now for winter color. Buy plants with unopened flower buds in cell packs for best value.

After the leaves have all turned yellow or brown, remove the foliage, wash any remaining soil from the tubers, and dust with sulfur powder to prevent fungus damage. Store in paper bags in a cool, dry area until planting time rolls around again next May.

Put Carnivores to Bed

Well-fed carnivorous plants will go into their winter dormancy soon. Place plants outdoors where they will receive full sun, and frost (if possible). Venus flytraps and pitcher plants will retreat underground for the winter. Tropical nepenthe requires humid conditions so provide plenty of humidity and light throughout the winter months.

Plant Sweet Peas

Fall is the ideal time to plant spring annual and perennial sweet peas from seed. Plant in rich, well-drained soil in sunny locations. Provide support in the form of a fence, stakes, or trellis. Protect seedlings from hungry birds, then stand back! Let the sweet pea explosion begin ...
