Every year around this time, people ask me why tulips that have been in the ground for two years look unkempt when they were so pretty and colorful the spring before, why they aren’t naturalizing and blooming like the daffodils, and why despite all the care they received, only a few weak, spindly leaves have emerged from the masses of bulbs. Tulips, however, are native to regions with cold winters.
For bulbs to store enough nutrients to nourish and repair the plant, it must be consistently cold. Here, it is a requirement that cannot be ensured. Therefore, you will be let down if you plant these recently bought winter-conditioned bulbs and count on them to come back every year. For those of us who have been gardening in the Bay Area for some time, providing tulips with the chilly temps they demand is the only way to treat them as the perennial perennials that they are.
Our work entails:
— Remove any spent flowers as they wilt to prevent the bulb from wasting energy on seed production. So that their nutrients can be returned to the bulb for the growth of the following season, allow the stalk and leaves alone to wither naturally.
— After that, take the bulbs in their containers to a storage area or dig up the bulbs (don’t worry too much about their roots). Remove and clean the bulbs after the leaves have become brown and dried, then let them air dry for about a week.
— It has always been difficult to store the dormant bulbs, but a reader provided this helpful advice: Put them in cardboard egg cartons with labels and a few holes poked in them. The bulbs will remain separate and receive enough air as a result of this. After that, store the cartons somewhere dim and dry.
— Start storing the bulbs in a cold place from the beginning of August for three to four months. 40 degrees or so in the refrigerator. Flowers will produce poorly or not at all at higher temps.
— Plant the bulbs with their noses up in rich, sandy soil in a place that receives full sun in the spring in late November or early December. Plant them 8 to 10 inches deep to achieve the coldest winter soil temperatures. When bulbs are planted deeply, they are surrounded by the chilly soil they need to grow strong roots. Additionally, it helps springtime plants produce big blooms. If there isn’t any rain, be sure to water.
In Northern California, when should you plant daffodil bulbs?
Why should we be thinking about spring and daffodils when it’s sweltering outside and October is rapidly approaching on the calendar?
For starters, it’s a good idea to consider daffodils. For another, you need to start working on it right away if you want to see those adorable yellow faces with their ruffled bonnets in spring.
You might even already be behind. While the current season is still in full swing, true bulb connoisseurs order their bulbs for the following season in the spring. But don’t worry. We’re here to provide you advice on what to do right away and later.
Getting started
Purchase your bulbs now and keep them chilled until you’re ready to plant them. Daffodils adore and require cold temperatures to grow, but we reside in the Bay Area, where winters are getting progressively milder. Your newly acquired bulbs need refrigeration to aid in their first year of growth because they are used to colder temperatures.
Bulb storage in the refrigerator is advised for four to eight weeks. To provide adequate airflow, they should be kept in an open plastic bag or a paper bag. Keep them away from food, such as apples, which can release ethylene gas and suffocate the flower inside the bulb.
Planting
The opportunity for planting your daffodil bulbs is available from late September to late November, depending on your microclimate. The majority of bulb growers advise delaying until November when the days, nights, and soil will all be significantly cooler.
Pick a location with good drainage and sunlight. Throughout the winter, bulbs left in wet ground will eventually decay. Although daffodils can grow in virtually any soil, they thrive best on slopes, on raised beds, or in containers.
Compost and soil additions should be worked into the bed before planting. If your soil tends to have a higher alkaline reading, add sulfur to the soil because daffodils like a slightly acidic environment.
For ordinary daffodil bulbs, dig a hole that is 6 inches deep; for miniature bulbs, dig a trench that is 2 inches deep. Put some Perlite at the bottom of the trench to help with drainage. Gypsum can also be used to break up clay soils. Add some fertilizer for bulbs, such as bone meal.
Put bulbs in the trench, pointed ends up, about six inches apart. If rain is not anticipated, softly moisten the area after covering and composting the top. Early in the spring, while the bulbs are actively growing, they will need water, but otherwise, nature should take care of the irrigation.
After the bloom
Enjoy your daffodils in your garden or as cut flowers, but hold off on trimming the leaves until the foliage has died back, often in May or June. The bulbs will be very busy producing flowers for the following year, and they require leaves for this to happen.
If you don’t intend to grow anything else in that area, experts advise leaving your daffodil bulbs alone. The latent bulbs may be harmed by the irrigation of the developing plants.
If you need to dig up your bulbs and store them until the fall, let them dry for a day or two, then store them in mesh bags or old pantyhose with lots of airflow in a cool environment.
Although some gardeners remove their bulbs each year, if you leave them in the bed, you should still remove and divide them every two to three years to avoid overcrowding.
Thinking ahead
While the displays are still gorgeous in April and May, start browsing seed and bulb catalogs and websites to choose a few new bulbs. Order now for delivery closer to planting season.
What month should daffodil bulbs be planted the latest?
But you can plant bulbs as long as the ground is usable! If you can dig a hole deep enough to plant, you can plant bulbs as late as January. Till the end of January, plant tulips and daffodils! They will grow roots this way throughout the spring and bloom later than usual.
Daffodils can be grown in California.
For the gardener, there is no instant gratification. Only the months that follow will allow us to enjoy what we plow, pull, or plant today. The gardener requires a lot of faith.
Consider bulbs as an example. The most lovely flowers bloom in the spring from an awkward brown glob. We plant and dream because we know they will arrive.
Daffodils are an example of a genuine bulb, but not all bulbs are. Some so-called bulbs are sold as corms, which are swollen stem bases; others are tubers; some are rhizomes, which are underground stems; and yet others are root fragments. But because they gather the vigor they require to bloom as a clan and store it in their deep machinery, they are treated like bulb plants and are not allowed to grow.
Additionally, bulbs are excellent for gardens that follow a Mediterranean or drought-tolerant style. We can thank the Dutch bulb industry for leading us to believe that bulbs desire lush environments. However, many bulbs come from regions with a Mediterranean climate, which features a dry summer followed by a wet but warm winter.
Anemone, iris, lily, daffodil, chionodoxa, tulip, hyacinth, cyclamen, and crocus are examples of bulbs and plants that resemble bulbs native to the Mediterranean and Middle East. Agapanthus, amaryllis, crinum, crocosmia, freesia, gladiolus, and ixia are examples of bulbs and plants that resemble bulbs native to South Africa.
While bulbs are still fresh, purchase them. Late bulb purchasers will encounter mushy, mildewed bulbs that seldom produce much in the spring, especially at big-box stores.
The largest, firmest, and freshest bulbs in the bin should be purchased. Find out if the bulbs you select need to be cold treated, which entails keeping them in your refrigerator’s vegetable section for six weeks. Some bulbs are offered for sale prepped, while others are not or don’t require it.
Better is more. My six tulips appear frail. Select about 50 gentle, yellow daffodils for maximum impact.
Late summer and early fall are too hot to plant in Southern California. Freesia, allium, ranunculus, crocus, and daffodils should be purchased in September, but they should be kept dry and dark until November.
Hyacinths and tulips require four to six weeks of chilling in your refrigerator’s vegetable drawer. Calculate, cool, and plant them before December.
Bulbs shouldn’t be kept in the same drawer as ripening fruit. Fruit gasses can make bulbs sprout.
The requirements vary slightly depending on the type. Find out the planting depth for each type of bulb before you buy it.
How are daffodil bulbs planted in California?
(1) View the numerous varieties of daffodils available by attending the Northern California Daffodil Society’s daffodil exhibits in March. Visit the exhibit gardens at Ironstone Vineyard in Murphys during March as well. Nothing compares to viewing the many blossoms. Choose the hues and shapes that you like the most.
(2) Request growers’ catalogs in late March or early April by writing, calling, or emailing them. In April or May, place your bulb order and make payment. The bulbs will be delivered to you by growers in September. Up until planting time, place them in a cool, airy location. when the soil temperature has lowered and nighttime temperatures have cooled.
(3) If you reside in a climate with warm summers and mild winters, you should place your new bulbs in the refrigerator for a few weeks after purchase in order to provide them with some of the winter chill they would otherwise lack. This will facilitate their climatic adjustment. In the middle to end of November, plant bulbs.
(4) Pick a sunny, well-drained location. Raised beds and hillsides work well. The secret is DRAINAGE. Dig your spade at least 12 inches deep. Raising the bed and adding well-rotted compost, soil amendment, or planting mix will help your clay. If your soil is alkaline, you might add sulfur to it since slightly acidic soil is ideal.
(5) Place your standard-sized daffodil bulb six to eight inches underground. Plant tiny bulbs 2 inches deep. It’s not necessary to be exact; they will adjust. In sandy soil, plant bulbs deeper than in clay. The bulb’s pointed end is at its top.
(6) Work some low-nitrogen fertilizer into the soil if they are to be left in place for several years. Top-dress your plants with a 5-10-10 sprinkle after planting. When the leaf-tips appear, top-dress once again with 5-10-10. Top-dress with 0-10-10 or 0-0-50 as they bloom. Avoid using fertilizer with a high nitrogen content.
(7) If you plant your bulbs before the start of the rainy season, don’t water them right away. Hold off until it rains, or at least until the time when it should rain. When bulbs sense dampness, they send out roots, which makes them more prone to fungus infection. Waiting is necessary because the basal-rot fungus, which is native to soil, goes dormant at cool soil temperatures.
(8) Daffodils require a lot of water to grow. After the blooming period, keep watering for about three weeks, then stop. After blooming, the bulbs create their bloom for the following year. (Your bulb’s first-year bloom is mostly the result of the bulb’s previous grower.)
(9) If your place is DRY in the summer, you can leave the daffodils up. You must excavate them if you plan to water them or grow other things there. MOISTURE + WARMTH = BULB ROT. The majority of tazetta plants for naturalizing will withstand summer water.
(10) Don’t trim the foliage until it turns yellow (usually late May or June). The time to dig the bulbs is then. The bulbs should be carefully cleaned and totally dried (at least a week, out of the sun). In the coolest location you can find, hang them in onion sacks (or pantyhose) until November. Rot in storage is minimized by good air circulation.

In how many groups should I plant daffodil bulbs?
The earliest point in early October, if you live in USDA zones 4 to 6, is the ideal time to grow daffodils.
Daffodils should be planted in bunches of 10 or more when being grown. All you have to do is arrange around seven bulbs in a loose circle, placing three in the center.
You shouldn’t combine various cultivars within each planting group for aesthetic reasons. If you plant just one variety together, the outcome will be better (such as a group of ten “Ice Follies, but not a group of “Ice Follies mixed with “Spellbinder, etc.). If you have enough room, you can use 25 or more bulbs to plant these in larger blocks.
In a formal garden with shapes like squares or circles, daffodils look lovely. Even plantings with a fish-like taper look fantastic.
When should daffodils be planted?
- After plants stop blooming, let daffodil leaves naturally fade back.
- If daffodils get too crowded and cease flowering, divide them.
Without daffodils, no spring garden is complete. Furthermore, they are frequently the only plants blooming in the garden in the early spring, so you really can’t have too many of them. Since daffodils are perennial plants, they return year after year and are among the easiest spring flowering bulbs to raise.
How to Choose Daffodils
The majority of daffodil cultivars grow best in milder climates because they need a period of cold weather each winter to encourage blooms for the following spring (zones 7 and lower). However, there are some types that thrive in warmer climates (zones 8 and higher), and bulb catalogs will always include them. There are numerous daffodil types available.
Daffodils come in all sizes, including some with enormous blossoms. Bulbs with peach, orange, yellow, pink, white, or bicolor flowers are available to purchase. There are season-specific early, mid, and late bloomers. You may enjoy three months of daffodil blossoms with careful planning! Even 100-day mixtures of bulbs are available in some stores, making it simple for you to take advantage of an extended daffodil season.
Where to Plant Daffodils
Daffodils should be planted in a sunny area that receives at least 6 hours of direct sunlight each day. The plants won’t blossom if they are planted in partial shade, but they will still produce green leaves. Daffodils, like the majority of bulbs, demand well-drained soil; otherwise, they are susceptible to rotting.
When to Plant Daffodils
Fall is the ideal season to plant daffodil bulbs (exact timing can range anywhere from September to late November, depending on where you live). When you plant, the earth must still be usable but the soil must have cooled. Daffodil planting requires soil that is 60 degrees Fahrenheit and 6 inches deep.
How to Prepare the Soil for Planting Daffodils
Mix 3 inches of Miracle-Gro Garden Soil for Flowers into the top 6 to 8 inches of the existing soil to prepare new planting sites. As a result, bulbs will receive the nutrition they require to develop a sturdy root system in time for spring blossoming.
How to Plant Daffodils
Daffodils can be planted singly, in groups (3 or 5 is a good number), or in rows. It is simpler to dig a trench or a large planting hole if you are planting many bulbs in a row along the edge of a flowerbed. You should plant them individually if you’re randomly putting them in a flowerbed or on the grass. The spacing between bulbs, regardless of how many you plant, should be 4 to 6 inches.
Each daffodil bulb should be planted with its pointed end (or tip) facing upward. When the bulb is inserted, dig the hole or trench so that the tip is 2 inches deeper than the bulb’s height. Therefore, a 2-inch long bulb should be planted 4 inches deep, while a 3-inch long bulb should be planted 5 inches deep (measured from the bottom of the bulb). After planting, give the soil plenty of water, and then add a layer of mulch to keep the area looking neat and to help the soil hold moisture longer.
How to Water Daffodils
Daffodils should be well watered at planting time and then once per week throughout the following three weeks. (Watering is essential at this period since the plants are developing their first roots.) After the first few weeks, don’t disturb the plants again until the spring, when they’ll start to grow.
When you notice daffodil leaves poking through the ground, it’s time to focus once again. While daffodils are growing and blooming, water the plants if your area doesn’t get any rain for two or three weeks. Spring storms typically supply enough of moisture. Once the blossoms have faded and the foliage starts to turn brown, stop watering because this signals the start of a time of dormancy and too much water might cause the bulbs to rot.
How to Feed Daffodils
A powerful combination of excellent soil and the ideal plant nourishment produces stunning garden outcomes. So, to aid the bulbs in storing nutrients for the following growing season, feed daffodils with Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food after they have blossomed in the spring. Feed as directed on the label every three months, and once the foliage turns brown, cease feeding.
What to Do with Daffodils After They Bloom
Daffodil plants will be prompted to focus energy back into the bulb rather than setting seed if wasted blooms are removed after blooming. (This method is known as deadheading.) After the plant has finished blooming, keep the leaves upright and unfolded so that the plants can use photosynthesis to produce and store food for the next spring’s blossoms. Before you do any trimming back, let the leaves naturally die down. If you want to create a screen around the daffodils if you don’t like how the foliage is beginning to turn brown, consider planting late-emerging perennials.
How to Divide Daffodils
Daffodils need to be divided in the fall if they are in full sun, have been allowed to naturally die back the previous spring, and are not flowering when they need to. Each spring clump that needs to be divided should have a golf tee placed next to it so that when they die back, you can easily locate them. Break separate the bulbs in each clump and excavate it. The biggest bulbs should be replanted at least two bulb widths apart. (When dividing, little bulbs might remain affixed to larger bulbs.) As if you were planting new bulbs, prepare the soil.
