Historically, flower bulbs have been associated with mysticism. The passage of time changes these ordinary objects into extraordinary displays of beauty from their initial rough and unclean state. We thought we’d address the most frequently asked questions about bulbs here because we get a lot of them.
The optimal time to plant spring flowering bulbs is in the fall. That refers to the months of September through November in Maine. However, if the soil or compost is manageable to cultivate, bulbs can still be planted after the first signs of winter frost.
There are various ways to plant flower bulbs, but the simplest is to just use a trowel to make a shallow hole. Gently disperse the bulbs across the planned planting area, letting them fall into any holes they “find,” to provide a more “natural” impression.
Depending on the size of the bulb you’re planting, you should plant it twice as deep as it is tall.
Larger bulbs should be planted with a distance of about five inches between them, while smaller bulbs should be put around four inches apart. You can plant them further closely, so that the bulbs are almost touching, to provide a bolder flash of color.
When grown naturally in well-drained soil, flower bulbs flourish. They also prefer some compost or organic material added to the planting soil. However, it’s crucial to keep in mind that you should constantly cultivate your garden soil before planting anything. It not only makes planting much simpler, but it also promotes a strong start for the bulbs’ new roots. As long as the pots are filled with compost or free-draining soil, bulbs can also be planted in them. They won’t require additional plant food during their first growth season if they are put in a container.
After planting your bulbs, thoroughly moisten the ground. Cover them with straw, fallen leaves, or compost if you live in a location that experiences severe frosts to provide them with additional protection.
Plants marked with a number sign (#) and a number are generally the same size as gallon pots; for example, #2 is equivalent to a 2 gallon pot, #3 to a 3 gallon pot, and so on. These plants are offered for sale in pots.
Plants with a height (such as 5-6′) give an estimate of the plant’s present height.
Plants that are measured in inches (such as 2.5″) are identified by their caliper, or trunk width.
Plants are typically larger when measured by caliper (inches) than when assessed by height (feet).
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.
How are daffodils grown in Maine?
Although the winters in Maine are long, the cool, damp spring season drags on longer due to our impatient need for new greenery, dry walkways, and more color in the surroundings. Additionally, it’s crucial to prepare ahead of time for bulb planting as farmers adjust to the growing issue of climate change. In a sea of mud and sloppy snow squalls, spring bulbs stand out as the colorful buoys of hope and bright spots. Snowdrops and ‘Yellow Winter’ aconite give way to pastel crocuses and purple dwarf irises. Then, the narcissus and early tulip display assures us that it is time to plant peas, lettuce, and fava beans, that we have survived, that tree leaves will unfold, that asparagus will turn to fern, and that strawberries will bloom once more. Here is all the information you require on planting fall bulbs in Maine.
Defining a bulb
A variety of plants having a big, bloated storage root or stem part from which a flowering plant grows every year are now included in the word “bulb.” True bulbs vary in type; others are corms or tubers. The majority of bulbs are planted in the fall in New England and other regions where the winters are chilly enough to freeze the ground, although certain delicate summer bulbs are planted in the spring and dug out in the fall to overwinter in cool storage.
It’s nearly as fun to plan a bulb show as it is to watch the multitude of bulbs light up. Light, soil drainage, fertility, bulb height, and blooming time must all be taken into account in your artistic vision.
Planning your fall bulb display
Your bulb garden can be designed for a continuous display of color. If you buy bulbs, the package and catalog will indicate whether they bloom in the early, middle, or late seasons (spring).
Height is another another factor. In between or in front of the mid-spring narcissus, I like to plant the shorter grape hyacinth. A low-growing plant should be positioned where it will be seen, such as next to a pathway or in a raised bed. Taller plants are more noticeable from a distance.
More people are affected by large plantings than by a few flowers. Plant a cluster of at least 10 of one kind of bulb. One or two bulbs are hardly noticeable. I enjoy mixing ten or more tulips with the same bloom time and a few different colors. Bulb catalogs frequently provide beautiful color combinations, often at a lesser cost than purchasing individual bulbs and creating your own custom color scheme. Additionally, you can purchase a pre-assembled collection with a layout guide, such as a low border classic collection.
Pay close attention to size and cost while purchasing bulbs. Smaller bulbs could be less expensive bulbs. Greater bulbs can produce several stems and larger blooms. Centimeters, the terms “exhibition size,” “top-size,” or the lesser “landscape size,” are used to describe bulb size. Bulbs can be purchased in-person, online, or through a catalog. While there is a huge selection in catalogs, you may feel the bulbs and choose sturdy, large ones in a garden center.
Climate and soil
Bulb prefers direct sunlight. Early spring bulbs planted beneath deciduous trees thrive because they receive light and can blossom before the tree fully unfolds its leaves. Mid- to late-spring flowers do better when planted in full sun. In comparison to north-facing land, southern slopes warm up quicker and encourage earlier bloom. Early blossoming is encouraged by a heat sink, such as a foundation. The crocuses I put in a raised bed in front of the sunroom’s foundation bloom 10 days earlier than the identical bulbs farther out in the yard. In order to extend their display, the same bulb kinds can be planted in several locations.
Bulb dislikes not to “get their feet wet, and in poorly drained soil they will develop badly or rot. Stay away from low-lying areas and beds where rain and snowmelt from the roof can collect. That sunroom bed collects too much rainwater from the glass, so I can’t put Narcissus in there. Narcissus bulbs are much less tolerant of water than crocus bulbs.
The planting of fall bulbs can be done in one of two ways. One is to set up a public space, and the other is to “In an existing garden or grassy area, naturalize or plant in individual holes.
When to plant
Planning is required for such salvation. Fall is the best time to plant bulbs. Bulbs can be planted well into November as long as the ground is not frozen, but October is the best month for planting because soil temperatures are in the 40 to 50 degree range. For bulbs to grow roots and get established before going dormant until spring, they need four to six weeks.
Ways to plant your bulbs and fertilizeer
To naturalize, arrange the bulbs in the appropriate arrangement, then use a trowel or bulb planter to dig each hole (a long-handled bulb planter is helpful here), fill the hole with 2 teaspoons of bulb fertilizer or bone meal and wood ashes, then set the bulb in position pointed side up, and then cover.
Turn the dirt in a garden well before planting. If your soil is predominantly clay, amend it by adding compost, peat moss, or well-rotted cow manure to the top 12 inches of the soil. This will bring the pH of the soil closer to the ideal range for 6 to 7-pH bulbs. Pull all the soil away to the proper depth for planting bulbs, then fertilize with bulb food, bone meal, wood ashes, or another source of phosphorus and potassium that bulbs require for healthy root development. After planting the bulbs at the designated distance, cover them with earth.
Dogs and skunks enjoy digging up bulbs to reach the bone meal buried beneath them. Consider using a bulb fertilizer without bone meal if these animals frequent your yard. Many animals may be scared off by blood meal, and most animals won’t be able to smell the bone meal if plants are dusted with ground cloves and black pepper after planting. Recur in the spring.
A combination of soybean or alfalfa meal, rock phosphate, K-mag (langbeinite), greensand, and kelp meal is an organic substitute for bone meal.
Mulching
Add 2 to 3 inches of loose mulch, such as shredded bark mulch, leaves, or other loose material, over the plant. Mulch reduces heaving and false starts while regulating soil temperature during the winter. Additionally, it aids in preserving a constant soil moisture level. Small bulbs should not be mulched severely since they may struggle to push up through a thick layer of mulch. Any bulbs can be covered with thicker mulch for further winter protection, which can be removed in the spring to allow the soil to reheat.
Pull back the mulch in the spring and top-dress the bed with compost for optimum growth. For ongoing weed control and moisture control, mulch may be reapplied.
Long-term care for fall bulbs
Your tulips may be too crowded, malnourished, or not receive enough light if they start to grow weak plants with no flowers. To prevent the generation of seeds, always pinch faded bulbs, especially on tulips. This keeps the bulb from deteriorating by forcing the energy back into it. It can be necessary to feed compost and bulb fertilizer to strengthen bulbs. They must be dug and split if they are crowded.
Fall bulbs
Perennials are fall bulbs. Many people have long lives. Some will branch out and form bigger clusters. Usually, species that naturally divide or multiply are noted in catalog descriptions. Every few years, some need to be dug out and divided or separated. To accomplish this, excavate the clump with a garden fork or shovel, then separate the bulbs and replant them in compost-rich soil with the proper spacing.
Summer bulbs
Some begonias, dahlias (tubers), ranunculus, and gladiolas are summer bulbs that are less hardy than others. Treat them as sensitive annuals in Maine. When the earth is warm and the risk of a frost has passed, plant them. Start them inside in pots to get a head start on the season and extend the blooming duration. Once the soil outside is warm enough, carefully move them outside. Both compost-rich soil and bulb fertilizer are necessary for them.
In the fall, before the ground freezes, dig summer bulbs. Spread them out to dry in a dry, shaded spot after digging. Once they have dried, you can store them in dry wood chips, peat moss, sand, perlite, or a mesh bag. Until the next spring, keep them in a cool (between 50 and 65 °F), dry, and low-humidity location. Never keep bulbs or tubers next to fruits that are emitting ethylene fumes (a naturally produced gas give off by apples and other crops in storage). Just before planting the next spring, divide bulbs as necessary.
A thoughtfully organized bulb display will pay off for years to come with very little work on your part. The evolution of color lifts the spirit and enlivens the surroundings.
Maybe it’s time to start cultivating winter crops in Maine now that you know how to sow bulbs in the fall.

Anytime between the first of September and the beginning of November, plant daffodil bulbs. In fact, your plants will do better the sooner you plant them. You may start planting your daffodil bulbs in August, according to Alan Titchmarsh. This is because your bulbs have the best chance to bed in and create a strong root system before putting on vigorous growth in the spring when they spend the entire autumn and winter in the ground.
What occurs if daffodil bulbs 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.
