Fall-planted bulbs produce hardy, easy to grow spring flowers that thrive in both sun or part shade. As an added bonus, bulbs multiply rapidly, and in just 2 to 3 years after planting, you’ll have at least double what you started with, making them reliable workhorses in the early spring garden.
There are two different methods for growing these cheerful spring bloomers, depending on whether you simply want to add color to your spring landscape or harvest them in abundance as cut flowers. No matter how you plant them, be sure to pick a spot that gets at least partial sun and doesn’t have standing water, since really wet soils will encourage bulbs to rot.
In the garden, narcissus make the most impact when planted en masse. For a dazzling display, I recommend ditching the bulb planter and instead planting clumps of at least 10-20 bulbs. Simply dig out a generous circle of soil, 6-8 inches deep, mix in a little bulb fertilizer, compost, and then plant your bulbs at a depth 3 to 4 times the bulb’s height, and as far apart as they are wide. Once your bulbs are securely in place, water deeply and then refill the hole with the soil you removed earlier. Add a few inches of well rotted compost on top to act as a mulch. Be sure to insert some type of stake so you remember where you planted them. If your intention is to grow narcissus solely for cutting then you can follow this same method but plant bulbs in long rows.
In the spring, harvest blooms that haven’t fully opened. If picked when the buds are fully colored, but still slightly nodding (also known as the “goose neck” stage) a solid week of vase life can be expected. Wear gloves when harvesting narcissus as they ooze a slimy sap that can cause skin irritation.
This slimy sap is also toxic to other flowers and will shorten their vase life significantly. To avoid affecting other blooms in an arrangement, you’ll need to “condition” the narcissus first. To do this, place freshly cut stems into cool water, on their own, for 2 to 3 hours; during that time, the stem ends will callus over and the toxic sap will stop flowing. After that, don’t recut the narcissus stems when adding them to arrangements because the sap will start leaking all over again. Of course, you can create an arrangement solely of narcissus, either just one variety or several, and the sap won’t be an issue.
