Cause Various Fungi, Penicillium spp. In Washington, penicillium hirsutum has been discovered on iris. In Denmark, P. tulipae and P. hirsutum both exhibited more severe symptoms than other species. These fungi typically target weak or damaged bulbs caused by various reasons, particularly damaged bulbs kept in damp environments. Additionally, reports of these fungi on other bulbous plants, such as crocus, gladioli, iris, and onions, have been made.
Symptoms Bulb storage causes brown stains to appear. On the bulb, the basal root plate, or in the spaces between the scales, a blue moldy growth may appear. Leaf initials and surrounding tissues may become internally discolored. The entire bulb could be impacted, becoming dry and hard. The foliage on sprouted blubs may be reddish-stunted.
- Dig bulbs at the appropriate time and handle them gently to prevent harm, such as bruises or sunburn.
- Store with gentle air circulation and moderate humidity.
- Dispose of damaged and unhealthy bulbs.
- Before replanting tulips on the same ground, give the area long rotations. Take out stray plants from earlier bulb crops.
Chemical regulation Sorted bulbs are soaked after harvest and promptly and thoroughly dried before storage. There have been reports of resistant fungus, which could make these treatments useless.

Can rotten tulip bulbs still sprout?
Q: I recently purchased some bulbs, but when I opened the bag, I saw that they had mold on them. They still grow, right?
A—Bulbs that are a little bit moldy may still bloom if they are still firm and haven’t started to rot, but you should definitely avoid purchasing any bulbs that exhibit these symptoms. If you decide to take a chance on them, consider employing an impromptu planting strategy to lessen any springtime disappointment.
I frequently like to plant bulbs in naturalistic, seemingly random patterns rather than in regular rows, with the exception of my cutting garden. This prevents me from having unattractive gaps if some of the bulbs fail. A little trick: Dig holes where the bulbs land on a lawn or planting bed after scattering a couple handfuls of them there (providing all the bulbs are at least their own width apart).
Plant bulbs in nutrient-rich, well-drained soil that has been improved with well-rotted compost and a fertilizer designed specifically for bulbs (available at garden centers).
It is recommended to plant tulip bulbs at a depth that is at least three times their height, if not four. If you’re planting a lot of bulbs, I advise utilizing a step-on bulb planter because it makes the digging much simpler.
Find huge, sturdy, weighty bulbs that are devoid of bad places the next time you go shopping. The papery, onion-like skin should be present, but it’s okay if it’s torn.
Spring-blooming bulbs should be planted as soon as possible after purchase. If planting the bulbs right immediately is not an option, keep them in a cool, dry area in a vented container like a box filled with wood shavings or a mesh bag hung from a peg.
What distinguishes sour cream from heavy cream, light cream, clotted cream, and creme fraiche?
A—Cream is typically just milk with more fat in it. Fresh milk was initially allowed to sit until the cream layer, or fat layer, collected on top; after that, it was skimmed off. Today, unhomogenized milk is typically spun in a centrifuge until it separates into two layers to create cream.
You can buy cream with different fat contents. Only heavy cream can be whipped, and it has a fat content of between 20% and 30% compared to light cream’s 40% to 60%.
Sour cream and creme fraiche are both milk products that have been thickened (and, in the case of sour cream, soured) by a fermenting agent, either an acidic chemical or a colony of non-harmful bacteria. Since creme fraiche can be boiled without curdling, it makes a good sour cream alternative in hot sauces and has a tangy flavor. Additionally, it tastes great as a fruit and berry topping and in salad dressings.
2 tablespoons of buttermilk or sour cream can be added to 2 cups of heavy cream to make crème fraiche at home. Combine, and let stand for 6 to 8 hours at room temperature. Before serving, cover and place in the refrigerator for at least 24 hours.
The traditional teatime topping for scones, clotted cream is a delicacy of Devonshire, England, and has a whopping 55% fat content. It is also great over fresh fruit. Unpasteurized milk is heated until a thick layer of cream forms on the surface to make clotted cream. The cream is skimmed once the milk has cooled.
Since all milk in the United States must be pasteurized, buying your milk directly from a farm is the only way to create clotted cream at home. Instead, search for it in supermarkets and specialty food shops.
How can I induce a verdigris finish on a copper pipe-made garden arch?
Verdigris is the lovely green finish copper develops as it ages and weathers outside. Thankfully, you won’t have to wait a long time for it to show up: You can create a verdigris patina on copper by simply misting it with vinegar. (A word of caution: Cooking acidic items in an unlined copper pan will instantly cause verdigris.)
How can mold on plant bulbs be removed?
Mold can range from a little annoyance that leaves patches on your daffodil bulbs to an aggressive problem that has led to rot. Before planting or storing, a little amount of mold can be removed by wiping or washing. To avoid failed bulbs and the propagation of the mold spores, more serious mold infestations that have softened the tissues of the bulb tissues must be disposed of.
Black or blue-gray mold stains should be removed using a new, slightly damp paper towel. Before storing or planting the bulb, let its surface dry.
Spray bulbs with a plant-safe fungicide if they have a little amount of white mold but are still firm to the touch. Then, let the bulbs dry for about a week on a pile of newspaper or on top of dry, clean sand.
Because they cannot be saved with fungicide and may harm other bulbs if they are stored or planted together, bulbs with white mold that have softened with rot at any point on the bulb should be thrown away.
- Mold can range from a little annoyance that leaves patches on your daffodil bulbs to an aggressive problem that has led to rot.
Can you still use a rotten bulb?
Daffodils (Narcissus spp.) are cheerful and resilient plants with vivid yellow, orange, or white flowers that usher in spring. However, you must plant healthy bulbs if you want the best and brightest flowers. Daffodil bulbs can occasionally grow mold while being stored. Depending on the type of mold and how far it has gone, the mold may be superficial and easily cured or it may be a significant issue. Before deciding whether and how to treat a bulb, each one must first be properly assessed.
Take a look at the mold’s color. Blue mold, which is brought on by the Penicillium fungus, is most likely present if it is bluish-green and fuzzy (Penicillium spp.). It is most likely narcissus basal rot if it is pink or white on the scales and brown, reddish, or purplish around the base (Fusarium oxysporum f.sp. narcissi). Crown rot can be identified by patches of white fungus and the development of tiny, firm brown dots (Sclerotium rolfsii). Although the second and third are more significant, the first is not a cause for concern.
Take note of the mold’s placement and the bulb’s texture. Blue mold can be seen anywhere on the bulb, however it typically only affects the outer scales. The scales and the bottom of the bulb, where the roots emerge, are the sites of narcissus basal rot. Additionally, rather than feeling firm, the bulb’s base will feel mushy to the touch. Crown rot can affect a single area of the bulb or the entire thing. Crown rot causes bulbs to feel damp and mushy at first, then dry and woody as the illness develops.
If there is blue mold, plant the bulb. Purdue Extension advises not treating it because it typically has no negative effects on the plants. However, soil bacteria will prevent the fungi from hurting the daffodils or other plants from spreading through the soil and causing damage to them.
Bulbs with narcissus base rot or crown rot should be thrown away. Penn State Extension advises against planting them. The bulb will eventually deteriorate to the point of being totally destroyed. Crown rot should never be planted since it spreads to the surrounding soil and can survive there for up to 10 years.
By keeping your daffodil bulbs dry and cool and planting only healthy bulbs, you can avoid mold in the future. Daffodil bulbs can also be sterilized by submerging them in hot water heated to 112 degrees Fahrenheit for three hours.
Why are the mold on my tulips growing?
Mold can sometimes grow on bulbs depending on the conditions. This is typically caused by early air exposure to the moist bottom of the bulb.
We advise carefully cleaning the bulbs with tap water if there is mold. Be careful not to hurt the roots. The next day, refill the vase with fresh water and repeat. Avoid overwatering the bulbs at all costs. When changing the vase, try to avoid dipping (splashing) the bulbs in water. Instead, keep the roots submerged in water. Keep the vase in a place that is dry and well aired, such as the majority of living rooms.
Please take a picture of any further issues you think may exist, such as broken bulbs, so that our grower can look at them and determine what else might be going on.
How to Save Tulip Bulbs For A More Colorful Garden Next Spring
One of the most popular flower bulbs is the tulip. They are the center of attention in the spring garden because of their brilliant colors and graceful shapes. Discover tulip bulb preservation techniques to enjoy a second season of beauty.
How to Save Tulip Bulbs
While most tulips won’t rebloom if the bulbs are left in the ground, certain small tulips naturalize well, multiply, and bloom for several years. Digging them up and storing them over the summer is the best option if you want to keep them.
- Dig the tulips up after the foliage has finished withering and dying back after flowering.
- After removing the soil, let the bulbs dry. Throw away those that are broken.
- The bulbs should be kept in paper bags or nets. Before transplanting them in the fall, label them and store them in a cold, dark spot.
How to Save Tulip Bulbs: Propagation
Tulips can be multiplied by propagation, increasing your stock. It’s possible that some of your tulip bulbs have sprung offsets or tiny new bulbs. Split these off from their parent bulbs, and then plant them in pots in a cold frame or in a protected area of the garden, at least 8″ deep. Make sure the soil is wet but not drenched. Be patient; they might bloom in the spring after that or they might need two seasons to mature before they bloom.
How to Save Tulip Bulbs Grown in Pots
Tulips cultivated in pots are less likely to blossom again because flower bulbs are more stressed when grown in pots and containers than when grown in the outdoors. It is preferable to throw them away once they have bloomed and plant new bulbs in the fall.

What’s causing the rot in my tulip bulbs?
Q. Last spring, my tulips performed terribly, so I bought some new bulbs and dug the old bulbs up last week. Many of them were rotting as I was extracting them. Can I replant bulbs here in the same location?
A. If you plant in the same spot, you’ll probably encounter the same issue. Several fungi that are soil-borne and persistent in the soil produce the illness known as tulip bulb rot. In damp, improperly drained soils, the disease is most severe.
I would prepare a fresh spot with loamy, well-drained soil for your bulbs. This will encourage disease-free tulip growth instead of unhealthy development. You might try planting daffodils or other spring bulbs in the old spot again. However, I would make sure to enhance drainage before planting by putting a ton of organic matter in the ground.
Q. We want to start using more organic gardening techniques in our garden and ultimately have an entirely organic garden. Do you have any ideas for a possible starting point?
A. I would start by thoroughly researching the organic farming approach. Natural and basic principles govern organic farming. However, organic farming success necessitates thorough preparation. You will benefit if you put effort into preparing and researching. If you don’t, you’ll probably fall short.
A. We want to lay down some landscaping fabric to keep the weeds out of our shrub beds, but we are worried about what it might do to the shrubs. Does the fabric pose a risk to the shrubs?
A. Landscape textiles should cause your shrubs little to no harm, but in my experience, they are considerably more bother than they are worth. The only exception would be if they were positioned beneath gravel pathways. In the majority of other situations, the mulch on top of the fabric will soon start to develop weeds. Additionally, it is quite difficult to dig through the fabric once it has been put. This makes adding new plants in subsequent years challenging.
1. Is your lawn equipment finished for the year? Make sure the fuel systems are gassed down. Gas that is still in the system can clog the carburetor and cause issues the following spring.
2. You don’t have to discard your fallen pine needles. They can be incorporated into ground cover beds or used as mulch to safeguard delicate plants.
3. Be sure to remove the burlap from the top of the root ball before planting a balled and burlapped tree. The burlap can all be carefully removed if the ball is solid.
