The temperature of the soil has decreased, and evenings are cool. November is generally the best month to plant. blooming; allow it to go away on its own. Daffodil leaves cutting very soon after flowering will cause serious bulb loss and less blooming the next year.
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.
Can bulbs still be planted in Northern California?
Winter bulb planting for later blooms You might think that your days of planting bulbs are finished after the first frost or snowfall. 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.
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.

What month is the ideal time to grow daffodils?
Daffodil bulbs should be planted in pots in the spring before they bloom in early autumn, ideally in September.
‘Forced’ bulbs, like the fragrant paper-white daffodil (Narcissus papyraceus), can also be planted indoors in September for Christmas or New Year’s Day blooming. See our article on planting bulbs for the holiday season.
How to plant
Planting bulbs is quick and simple. Just make sure you install them three times the height of the bulb below the surface of the ground. This will make sure they continue to bloom healthily for many years.
For the most impact, plant the bulbs more densely and less deeply for creating temporary spring displays in pots. But after the show is over, plant the bulbs deeper when you transplant them into the garden.
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.
Daffodils grow 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.
What occurs if daffodils are planted too late?
As of late January, if you are reading this post, the answer is “not yet,” at least for tulips. One of my most popular articles over the past eight years is “When is it too late to plant spring bulbs?,” which was first published in November 2016. I’m pinning it to the top of my site for the upcoming few weeks in the hopes that it will inspire a few more readers to find abandoned brown bags full of bulbs and give them the gift of life. If you move quickly, displays such to the one below are still conceivable.
The Watch House, November 17th 2016
This year, I am late with everything: I am late with planning my vacation, getting ready for Christmas, and planting my spring bulbs. This is an uncomfortable situation for someone who loves to always be prepared and early. However, am I now too late to care for my narcissi or plant my tulips? Definitely not.
The fear of being late is much worse than the reality, as it is with most things in life and gardening. Generally speaking, early blooming bulbs should be properly buried in the ground at least six weeks before there is any chance of the soil freezing (an increasingly unusual occurence in the South of England). However, even if planting is postponed until the New Year, the majority show an astonishing level of forbearance. Your bulbs have a decent chance of putting on a respectable performance as long as the ground can be dug through and is not saturated with water.
It is well known that narcissi love to be planted in the late summer or early fall. This is wise advice if you want to be sure of receiving premium flowers. To establish themselves while the earth is still warm, daffodil bulbs prefer time. Even when kept in their packages, they frequently grow roots and are therefore vulnerable to drying out. Before going to the trouble of planting, make sure the bulbs are full and sturdy to avoid wasting your time. If they have already begun to sprout, don’t worry, but be careful handling them to avoid damaging the growing tips. Daffodil bulbs planted later in the year will almost likely blossom later; some may even grow ‘blind,’ flowering the following year. Bulb clump-up will occur more slowly in small, weaker bulbs, but they should eventually recover.
On the other hand, warm, moist conditions can promote disease and fungus issues in early-planted bulbs. Tulips are particularly impacted by this. Tulips need to be planted once the weather gets chilly, whether they are in the ground or in containers. By doing this, harmful diseases like Tulip Fire, which results in ugly brown blotches on tulip foliage and blooms, will be slowed down or prevented from spreading. Other than in pots with narcissi, I never plant tulip bulbs before November. Planting in sterile, clean compost lowers the chance of disease development and is quite low risk. Tulips have a long planting window because cold weather typically doesn’t hit the UK until December, so waiting shouldn’t prevent flowers from blooming. On a recent episode of Gardeners’ Question Time, Bunny Guinness said that planting tulips as late as January or February can still provide a respectable display even though it isn’t “textbook.” Because bulbs have a cunning habit of catching up with one another as soon as spring begins, I have waited until as late as early March and still enjoyed blossoms a couple of months later.
Gardeners who are bold enough to wait until the last minute to buy their bulbs frequently benefit from excellent discounts. Even though it is totally feasible, most retailers are eager to offload surplus stock at reduced rates in November. In fact, the bulbs will likely be in better health than any that were bought in advance and kept at home. If you don’t care about buying particular varieties, you’d be wise to maintain your composure until the vendors lose theirs.
I would offer three bits of advice if, like me, you have ordered bulbs but haven’t had time to plant them.
Keep them dark, dry, and chilly. While necessary for kicking off growth, warmth and moisture are the enemies of dormant bulbs. Never put them in sealed containers or plastic bags where they may sweat; instead, properly store them in paper bags or well-ventilated cardboard boxes. Place the packages in a well-ventilated area, ideally not in a closed cabinet. I even went so far as to arrange my bulbs in a single layer on a tray and position it next to a dehumidifier. This ensures they won’t get wet. Every week, I examine the bulbs and take out any that are starting to become soft or moldy. The smell of festering fritillarias is something one should only experience once in a lifetime. These will soon contaminate the entire thing, and they can smell rather nasty in the process. Find a spot to hide that is pleasant and dark because intense light will also accelerate development, even in the absence of food and water (bulbs are preloaded with both).
It’s still worth a shot, even if you find a packet of tulips, daffodils, or hyacinths hidden at the back of the garden shed after the Christmas sherry and New Year’s fizz have worn off. By design, bulbs are resilient and full of energy to keep them going through good and terrible times. It will be a nice surprise if they blossom and grow, and if not, you can always start over the next year a little early.
