When the first signs of greenery appear in the late winter or early spring, treat with granular bulb fertilizer. When bulbs bloom, liquid fertilizer can be applied to the leaves. A 4-12-12 that is sold in our gift shop is what we utilize.
Inspect foliage tips
Check for “fire heads on tulips” in late January and early February. This is seen as gray fuzz on the foliage’s tips. Actually, these are botrytis spores, which can spread to all of your tulips. To control the disease, remove the entire affected plant and bulb and discard them. Botrytis is known as “Fire Flight” because to its quick spread (do not mulch diseased plants; it will only create a bigger problem). Healthy Tulips Infected Tulips
Snap off Heads after bloom
Your tulips must blossom completely before the seed pods may be removed to prevent the flowers from going to seed. In order for the bulb to blossom the next year, all the nutrients and energy in the stem and leaves are able to flow there. The stems should not be bent or tied with a band. Let the stems expire on their own. You can plant annuals and perennials on top of your bulbs to add color for the remainder of spring and summer while the bulbs recover for the next year.
Dig Every 3-4 Years for Ground planting
Tulips don’t need to be dug up and divided every year, but if they were planted in the ground, they should be dug up at least every three to four years. Make sure they are not in a part of the yard where they will be watered all summer if you are not digging them up every year. Your bulbs will rot or die if you water them too much in the summer. Try to water the bulbs once a week or fewer if they are in an area where you must water them.
What occurs if tulip bulbs are not dug up?
Gardeners are not required by law to dig up tulip bulbs every year or even at all. The majority of bulbs actually prefer to remain in the ground, where they will bloom the next year if left alone. Tulip bulbs are only dug out by gardeners when the plants appear less robust and produce fewer flowers, which may be an indication of overcrowding.
Dig up your tulips if you think they aren’t doing as well as they did previous year. Discover the best time to dig up tulips before you proceed. It is better to avoid digging up bulbs altogether than to do it at the incorrect moment.
Can bulbs be left in the ground all year long?
Want to awaken to a garden full with flowers? Afterward, start digging and plant your bulbs. Once they are planted, the majority need little or no maintenance. Hardy bulbs can also be safely placed in the ground for multiple years.
Plant your bulbs in accordance with the planting instructions on the package for the best results. Daffodils and snowdrops, for example, are early-spring bulbs that should typically be planted by late summer or early fall. Tulips with a late bloom can be planted up until the ground freezes in November.
Can’t start gardening right away? To avoid mold or mildew, Rich Obal, a horticulture with the Rutgers Cooperative Extension Service in New Brunswick, New Jersey, advises taking new bulbs out of the bag and keeping them in a dry location (a tray filled with peat moss is a good temporary haven). Keep unplanted bulbs at 40 degrees Fahrenheit as well.
Ready, Set, Dig
Look for areas in your yard where the soil isn’t always wet while determining where to grow bulbs (excessive moisture can cause them to rot). Stay away from places close to your sprinkler or hose. Also, consider height. For example, small snowdrops work well in front borders, whereas huge tulips and allium go at the back of your garden.
Dig out the soil to the required planting depth and loosen the soil around it to increase drainage and promote root growth. Water the soil to make it workable if it is really dry. To fertilize sandy soil, combine peat moss or leaf compost. Add peat moss or sand to soil that resembles clay. Avoid using fresh manure or potent commercial fertilizers.
Following the spacing recommendations on the package, firmly put the bulbs with the pointed side facing up. (Leaving more space between your bulbs than is advised won’t harm them, but it won’t produce the best results.) Fill the soil around the bulbs with water. Add two or three inches of mulch on top in colder climates. Just make sure to get rid of the mulch as soon as the first foliage shoots appear in the early spring. Obal cautions that if the mulch isn’t removed, blooming will often be slowed down.
Dig out the entire space with a shovel if you’re preparing a flower bed. This will guarantee that all of your bulbs bloom at the same time. Dig one hole at a time with a trowel or a bulb planter to plant individual bulbs, especially ones with huge blossoms that stand out on their own or in areas where you don’t want to disrupt tree roots.
Where should I dig? Each type of bulb has a specific planting depth. Use this “green” rule of thumb or adhere to the instructions on the packaging for the bulbs: Place each bulb three times as deep as it is in the ground. Go a little deeper when planting bulbs in really cold climates, but make sure the subsurface is well-drained, advises Obal. Calculate the distance from the soil’s surface to the bulb’s shoulder.
Bulb After-Care
The majority of bulbs can be preserved indoors or left underground all year. Never pluck a bulb’s leaves while they are still green after it has flowered; always allow the foliage to die back naturally. The foliage on bulbs gives them strength, enabling them to expand and produce fresh blossoms the next year. This procedure is the most important phase of a bulb’s life cycle and it lasts for weeks after the petals fade. Try interplanting annuals to conceal wilting leaves. Obal advises tying up long iris stems, for instance, to make your annuals more visible.
When existing bulbs are growing new roots in the spring, it is the ideal time to fertilize them. Obal cautions, “but be very careful not to overfertilize.” Apply compost or a slow-release fertilizer made especially for bulbs to the soil’s surface.
Lift the larger bulbs and transplant them the following fall to maintain the hardiness of long-stem tulips and hyacinths. (They will likely get smaller every year if left in the ground.)
Before digging up your bulbs for storage, there’s no need to wait until the leaves have turned entirely yellow. Place the lifted bulbs with foliage still attached in a cool, airy location around 8 to 10 weeks after blooming. Your bulbs will be ready to plant again the following fall if you store them in a box or basket and keep them in the garage or basement after the leaves have died.
Planting Pointers by Variety
Allium. in the spring or summer blooms. The majority of bulbs tolerate some shade but prefer full sun (six hours or more of direct sunlight per day). Like the majority of bulbs, allium needs soil that drains well.
Anemones. well in either full sun or light shade. prefers enriched, well-drained soil.
Crocus. This spring-heralding bloom prefers full to partial sunlight. You can plant early-blooming crocuses directly in your grass. Before you have to mow, the flowers will bloom and fade. According to Obal, they can be planted under deciduous trees because the majority bloom before trees leaf and provide shade for the garden.
Daffodils. This resilient bulb does best in filtered shade or early to midspring sun. Tip: Use a fork to dig out, divide, and replant daffodils if they get overcrowding over time.
Eranthis. In the early fall, plant these early bloomers. Plant the bulbs with the “eyes” facing up after soaking them in water for a few hours. This bulb may not bloom the first year since it prefers partial shade.
Galanthus. This little flower, sometimes known as a snowdrop, is among the earliest to bloom in the spring, blooming even when there is snow on the ground. It works well for borders and is simple to cultivate in either full sun or moderate shade.
Hyacinths. fantastic for bedding. However, when planting, make sure to use gloves because the bulbs could irritate your skin. favors the full sun.
Iris. These can be cultivated in either full sun or partial shade depending on whether they are bulbous or tuberous iris. Plant in a soil that drains properly.
Muscari. These bulbs, often known as grape hyacinths, bloom in the early spring. They do nicely on well-drained soil with either full sun or light shade.
Scilla. The ideal conditions for these long-lasting bulbs to develop are moist, rich soil, full light, or partial shade.
Tulip. The early spring blooms of this adaptable bulb come in a variety of hues. Plant in at least five-person groupings for the most dramatic impact. Although they fare well in some shade, tulips prefer the sun. For the optimum bulb growth, “deadhead” the flowers by clipping them for indoor usage or as soon as they fade.

What happens to tulip bulbs once they have bloomed?
Once the blooms have faded, remove the seed heads to encourage your tulips to blossom once more the following year. After the foliage has naturally died down, dig up the bulbs around six weeks after they have bloomed. Any that are infected or damaged should be discarded after drying. Replant in them in the fall after keeping them in trays or nets in a dark, dry location over the summer.
How long are tulip bulbs good for?
Iowa’s AMES
Many gardeners wonder why their tulips and daffodils stop blooming. Horticulturists from Iowa State University Extension and Outreach provide advice on what to do if these popular spring plants don’t bloom.
Why are my tulips no longer blooming?
Most contemporary tulip varieties have a three- to five-year blooming period. Tulip bulbs lose their strength rather rapidly. Large, floppy leaves but no blooms are produced by weak bulbs.
Choose planting locations with well-drained soils and at least six hours of direct sunlight each day to extend the length of time tulips are in bloom. When the tulips have finished flowering, immediately take out the spent blossoms. The production of seedpods deprives the bulbs of a large portion of the food produced by the plant’s foliage. Last but not least, let the tulip foliage gradually wither away before removing it. Tulips that don’t have enough food stored in their bulbs can’t bloom.
Tulip bulbs that are no longer in bloom should be dug up and thrown away. (Weak, little tulip bulbs are probably doomed to never bloom again.) In the fall, plant new tulip bulbs.
Some tulip kinds (classes) bloom successfully over a longer length of time, although the majority of current tulip cultivars bloom effectively for three to five years. The longest-blooming hybrid tulip is typically the Darwin variety. Fosteriana tulips, commonly referred to as Emperor tulips, also bloom admirably and persistently.
My daffodils produce foliage in spring, but no longer bloom. Why?
The plants weren’t able to store enough food in their bulbs the previous year if the daffodils aren’t in bloom. After blooming, daffodil foliage normally lasts for four to six weeks. The daffodil leaf is producing food at this time. A large portion of the food is carried down to the bulbs. Daffodils need to store enough food in their bulbs for them to bloom.
It’s possible that trimming the leaves before it has naturally fallen back will hinder the plants from storing enough food in the bulbs. Before removing the daffodil leaf, let it totally wither.
Because of the lack of sunlight in May and June, plants in partial shadow might not be able to store enough food in their bulbs. When the foliage has withered back, dig up any daffodils that were growing in partial shade and plant the bulbs somewhere that gets at least six hours of direct sunlight every day.
Due to overcrowding, large clumps of daffodils may stop blooming. After the foliage has withered, large daffodil clumps can be excavated. Replant the bulbs as soon as you have separated them. Additionally, bulbs can be dried for a few days, put in mesh bags, kept in a cold, dry spot, and then planted in the fall. When given the proper care and growing conditions, weak (non-blooming) daffodils can bloom once again.
After they have flowered, should I pull up my tulips?
These likewise bloom in the spring, although the flowers are often smaller and shorter in height. They are either named cultivars that are closely related to them or wild species. They look delicate and frequently naturalize (grow in numbers) in gardens. Some plants do better in a more protected environment, such a greenhouse or cold frame.
Border tulips
In the fall, nurseries and garden centers sell a variety of border tulips as dry bulbs. They come in labeled bundles or are sold loose. Select bulbs that are sturdy and mold-free. Sometimes the papery brown skin peels off, although this has no impact on flowering. For each sq m (yd) of garden you wish to plant, you should buy between 25 to 50 bulbs to create a really good flowering display (using less than 25 is feasible, but you should underplant with forget-me-nots, pansies, wallflowers, or primroses so that it doesn’t seem gappy). A 45cm (18in) wide pot would need about 12 bulbs for a container, but you can raise this to 20 bulbs for a bigger display.
In the spring, gardening supply stores and supermarkets frequently have bulbs grown in containers available if you missed buying and planting bulbs in the fall. Purchase them ideally before they bloom fully.
Specialist tulips
These are occasionally offered at stores that sell gardening supplies, but you might need to mail order them from an online store or specialized nursery. Use the RHS Find a Plant feature here to locate a supplier.
These tulips, which are also known as English Florists’ tulips, contain petals with multicolored streaking or flaming patterns. The tulip shattering virus is to blame for their appearance (TBV). They can be grown by infecting ‘breeder’ tulips, though they are less usually offered for sale. Visit the Wakefield and North of England Tulip Society for further information. Flame variations like Tulipa ‘Olympic Flame’ have the appearance but are not virus-infected if you like the way these types look but don’t want to breed them.

When to plant tulips
When the plant is dormant in the fall (September to November), dry bulbs are planted. If planting bulbs right immediately is not an option, keep them in a cool, dry spot. Plants purchased in containers from garden merchants in the spring are planted immediately and will bloom in a few weeks.
These are used as bedding plants for spring color because they often only flower dependably the first year. It is not necessary to have proper soil for bedding because bulbs will bloom just fine in any condition as long as the land is not flooded. Once the bulbs have completed flowering, they are pulled up. Some tulip cultivars can, however, be left in the ground and will frequently continue to bloom for several years (see Tulips that last more than one year). In this case, well-drained soil in direct sunlight is more crucial because it will make the display last for longer.
For spring color, bulbs can be planted in containers to brighten up paved areas and serve as brilliant focal points, as well as in borders between perennial plants (which continue the seasonal display by blossoming later in the year). Alternately, use tulips into a bedding design together with other spring-flowering plants. For greater impact, plant low-growing flowers that bloom at the same time as tulips, such as pansies, primroses, and polyanthus, as well as forget-me-nots (Myosotis sylvatica), wallflowers (Erysimum cheiri), and primroses (Viola).
Cut tulips from the border are excellent. To make choosing easier, grow in rows. Cut flowers as soon as the bud begins to display color but before it fully opens.
These often need particular growing circumstances. Planting in gravel and rock gardens (where the soil is free-draining) and in pots in greenhouses can provide some of the conditions that some plants require, including very good drainage and full sun (in free-draining compost). Plant other tulips behind bushes and trees because they prefer part-shade and moist soil (for shade).
This list offers extra information about a number of commonly found specialized tulips:
- Although they can be cultivated in greenhouses, Tulipa ophanidea Whittallii Group, T. kolpakowskiana, and T. saxitilis Bakeri Group prefer good drainage and full sun. Due to their slightly bigger size, they would also do well in gravel or rock gardens.
- In pots of freely draining grit in your greenhouse, little alpine species like Tulipa turkestanica and T. hageri ‘Splendens’ are probably best grown. Their blossoms can be admired at eye level on the greenhouse bench while being protected from the elements here.
- The tulip species Tulipa sylvestris and T. sprengeri may both grow in partial shade on moist soil. Grow them in wet borders in the garden under some deciduous trees or bushes for shade (those that lose their leaves in winter). In grassy areas or meadows, where their population can grow, it is also worthwhile to try to naturalize them.
