Question 1

Can I use Epsom salt on my flowers?

Accepted Answer

Epsom salt (magnesium sulfate) benefits flowers by providing magnesium, which promotes chlorophyll production and flower development. Apply 1 tablespoon per gallon of water monthly during the growing season, especially for roses, tomatoes, and container plants that quickly deplete soil magnesium. However, most soils contain adequate magnesium, so test soil before applying or you may create nutrient imbalances.

Question 2

What flowers can I grow in shallow soil over ledge?

Accepted Answer

Shallow-rooted flowers for ledge or rocky areas include sedum, sempervivum, dianthus, creeping phlox, and many alpine species adapted to thin soil. These plants tolerate drought, require excellent drainage, and thrive in challenging conditions where deeper-rooted plants fail. Add pockets of quality soil mix where possible, mulch with gravel for moisture retention and aesthetics, and accept slower growth than plants in deeper, richer soil.

Question 3

How do I start flower seeds indoors?

Accepted Answer

Start seeds indoors 6-8 weeks before the last frost date using sterile seed-starting mix in cells or flats with drainage holes. Provide bottom heat (70-75°F) for faster germination, adequate light (12-16 hours daily using grow lights), and consistent moisture. Transplant seedlings to individual pots once they have 2-3 true leaves, and harden them off gradually before planting outdoors.

Question 4

What is the difference between direct seeding and transplanting?

Accepted Answer

Direct seeding involves planting seeds directly in the garden where plants will grow, working well for hardy flowers that dislike transplanting like poppies and larkspur. Transplanting uses seedlings started indoors or purchased from nurseries, allowing earlier blooms, better plant spacing, and protection during vulnerable seedling stage. Direct seeding is more economical but takes longer to flower and requires thinning and weed management.

Question 5

What flowers can help deter garden pests naturally?

Accepted Answer

Pest-deterrent flowers include marigolds (whiteflies, aphids), nasturtiums (aphid trap crop), lavender (moths, fleas), and alliums (various insects) that repel or confuse pests through strong scents or chemical compounds. Interplant these flowers among vegetables and susceptible ornamentals, and combine multiple strategies for best results. While these plants help, they don't eliminate pests entirely and work best as part of integrated pest management including proper sanitation and encouraging beneficial insects.
