Generally, it is recommended to plant hardy bulbs (especially daffodils) and tulips in October to give them enough time to root before winter. But it is certainly not too late to plant them now, as the temperatures have been warm, leading to a warm soil temperature. As long as the soil temperatures are above 40 degrees F, the bulbs should continue root development. Most garden centers still have a good selection, and they can be purchased on-line also. Try to select large, firm bulbs that have not begun to sprout. While many bulbs can adapt to a wide range of soil types, none can tolerate poorly drained soil. Prepare the planting bed by adding organic matter such as peat moss, well-rotted manure, or compost and mix into the soil.
Good fertility is essential. Use a fertilizer relatively high in nitrogen such as a 29-5-4, 27-3-3, or something similar. Apply these fertilizers at the rate of 2/3 pound per 100 square feet. Organic sources of fertilizers low in phosphorus include blood meal (12-0-0) applied at 5 to 10 pounds per 100 square feet, cottonseed meal (6-0.4-1.5) applied at the rate of 10 pounds per 100 square feet and soybean meal (7-2-1) applied at the rate of 8 pounds per 100 square feet. Mix all fertilizers and amendments thoroughly with the soil before planting the bulbs.
The size and species of the bulb determine how deep to plant. In general, the depth to the bottom of the bulb should be about 2 to 3 times the size of the bulb, but check the planting instructions specific to each particular flower. We recommend planting in bare or open areas in the landscape bed, to compliment shrubs and other plants growing there. Plant in
bunches, with at least 6 in each bunch. Don’t plant out in the lawn, as it not only looks weird, they will also be harmed when applying turf weed-control products during the spring.
