Monk's-hood (Aconitum napellus) Flower, Leaf, Care, Uses

Monk's-hood can be a thirsty plant that enjoys consistently moist soil that stays damp to the touch. Once established, this plant can be slightly drought tolerant for short periods of time. If your plant begins to wilt or has curling leaves, it needs more water. Be careful not to overwater to avoid root rot, and avoid the roots becoming waterlogged.

Fertilization

Monk's-hood does best in organically rich soils. Compost added in the spring will boost the soil. When fertilizing, choose a solution that contains phosphorus, which encourages healthy root development. A water-soluble, quick-release fertilizer that is organically rich, such as fish emulsion, is ideal. Apply at planting or during the first growing season.

What is the best way to water my Monk's-hood?

When watering the Monk's-hood, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Monk's-hood comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Monk's-hood too much or too little?

Both overwatering and underwatering will be detrimental to the health of your Monk's-hood, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Monk's-hood, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Monk's-hood have become brittle and brown.

It is crucial that you notice the signs of overwatering as soon as possible when caring for your Monk's-hood. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Monk's-hood grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Monk's-hood is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Monk's-hood?

If your plant is in a pot. The most precise way to decide whether your Monk's-hood needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water.

If you grow your Monk's-hood outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Monk's-hood can show an admirable ability to withstand drought.

How much water does my Monk's-hood need?

When it comes time to water your Monk's-hood, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Monk's-hood at different growth stages?

The water needs of the Monk's-hood can change depending on growth stages as well. For example, when your Monk's-hood is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Monk's-hood will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Monk's-hood will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Monk's-hood more water at this time.

How should I water my Monk's-hood through the seasons?

The Monk's-hood will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Monk's-hood will contract a disease.

What's the difference between watering my Monk's-hood indoors and outdoors?

It is most common to grow the Monk's-hood indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Monk's-hood to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Monk's-hood very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Do I need to prune my Monk's-hood?

Far from damaging the plant, regular pruning will actually encourage Monk's-hood to produce more blooms. There are two primary forms of pruning for Monk's-hood. The first is deadheading, which is the gardening term for removing spent flower heads once they start to wither. This concentrates the nutrients for the other flowers and allows the plant to flower better. The final process for pruning Monk's-hood is the removal of yellow and diseased leaves, which increases plant ventilation and light penetration and facilitates plant growth. When nature runs its course, Monk's-hood will bloom once, produce seed heads, and attempt to reproduce for the rest of the year. But, by consistently removing flower heads before they go to seed, you encourage the plant to continue producing more blooms for a longer flowering time. When the plant starts to wilt during the full, you should cut off the wilted part above the soil as well.

When is the best time to prune my Monk's-hood?

There are two primary forms of pruning for Monk's-hood. The first is deadheading, which is the gardening term for removing spent flower heads once they start to wither. This concentrates the nutrients for the other flowers and allows the plant to flower better. The final process for pruning Monk's-hood is the removal of yellow and diseased leaves, which increases plant ventilation and light penetration and facilitates plant growth. Since Monk's-hood requires two types of pruning, you’ll be trimming your plants throughout the growing season. Pinching is most effective in the early spring before the plant develops any flower buds. Removal of yellowing or diseased leaves can be done at any time during the growing season. When nature runs its course, Monk's-hood will bloom once, produce seed heads, and attempt to reproduce for the rest of the year. But, by consistently removing flower heads before they go to seed, you encourage the plant to continue producing more blooms for a longer flowering time. Finally, deadheading takes place as soon as the plants are producing full flower heads. Expect to take off spent blossoms from mid-summer through the first frosts of fall. When the plant starts to wilt during the full, you should cut off the wilted part above the soil as well.

What tools should I prepare for pruning my Monk's-hood?

Monk's-hood doesn’t take much special equipment for pruning. A basic pair of scissors or garden shears should do the trick. It’s a good idea to ensure they are clean before use—you can soak them for thirty minutes in a solution of one part bleach diluted in nine parts water. This reduces the risk of spreading disease lingering on contaminated equipment into your flower garden. Some gardeners avoid using tools altogether and merely pinch off the blossoms with their fingertips. That can be a faster technique, but you run a larger risk of bruising the plant stems or accidentally pulling them out of the ground completely.

Are there any instructions for pruning my Monk's-hood?

Here’s an overview of pruning instructions for Monk's-hood based on which of the two types you’re completing. By completing these two types of pruning over the lifespan of your Monk's-hood, you’ll encourage them to produce bigger, better flowers for far longer than the plants would otherwise. It only takes a few minutes to complete each step of the pruning process, and you’ll reap the rewards of your efforts for weeks to come. Deadheading Deadheading is a fast, easy way to refresh your garden by removing old flowers and providing space for new ones to take their place. You can use your fingers to pop off old flower heads as soon as they look tired, although you’re less likely to damage the plant if you use shears instead. When deadheading, make sure you cut well below the flower so that you aren’t left with a long, flowerless stem sticking out in your garden bed. Instead, cut the stem to just above the point where the side stem joins the main plant. Remove yellow and diseased leaves, this increases the ventilation and light penetration of the plant and facilitates its growth. When pruning, the leaves need to be trimmed off together with the petiole. It is best to use sterilised scissors to cut them off. Note: It’s a good idea to ensure scissors or garden shears are clean before use—you can soak them for thirty minutes in a solution of one part bleach diluted in nine parts water. This reduces the risk of spreading disease lingering on contaminated equipment into your flower garden.

What is the optimal temperature for Monk's-hood?

The best temperature for Monk's-hood depends on the time of year. There are two primary seasons to discuss for temperature: the growing season, and the dormancy season. During the growing season, once Monk's-hood has begun to sprout, the ideal temperature range should be anywhere from 65~80℉(18~27℃). Any colder than 15℉(-10℃), and the plant will suffer; its leaves may brown and wilt, but if this is a short cold snap, then Monk's-hood may be able to survive with some help.

During the warmer parts of the year, Monk's-hood will need to be similarly protected from temperatures that are too high. 95-105℉ (35-40℃) is the top of this plant’s temperature range, and anything above that will compromise the integrity of the foliage and blooms of Monk's-hood. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Monk's-hood to recover from. There are quite a few ways to combat this issue that are quick and easy!

Temperature requirements for first year or seedling Monk's-hood

If this is the first year of your Monk's-hood outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year Monk's-hood, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your Monk's-hood inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage.

It’s also a good idea to plant Monk's-hood in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year Monk's-hood should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.

How can I protect Monk's-hood from extreme temperatures?

If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Monk's-hood from frost or cold damage. If you’re growing Monk's-hood in a container, then the container can simply be brought inside in bright, indirect light until the temperatures rise up over the lower threshold again. Another option that’s better suited for ground-planted Monk's-hood is to use mulch or horticultural fabric to create an insulated barrier around the plant, which will protect the plant from frost and cold wind.

For temperatures that are hotter than 80℉(27℃) in the shade during the day, be careful to only expose Monk's-hood to six hours or less of sunlight per day, preferably in the morning hours. Putting up shade cloth, or a fine plastic mesh, can help reduce the amount of direct sunlight that hits the plant during the hottest parts of the day. You can also install a misting system that allows for a slow release of cooling mist around the base of the plant during the day to lower ground temperatures.

Dormant season temperature recommendations for Monk's-hood

During the cold winter months, Monk's-hood needs a certain measure of cold in order to stay in dormancy until it’s time to sprout. Sprouting too early, that is before the danger of the last frost has passed, can be fatal to Monk's-hood, especially if it’s already had a head start when the frost hits. Winter temperatures should ideally stay below 32℉(0℃), but if they get up to 40℉(5℃), everything will be just fine.

An unexpected warm spell during the cold months, which can happen in more temperate climates like woodland rainforests, can trigger a premature sprout from Monk's-hood. In this case, if there’s still imminent danger of frost, you may want to try covering it with clear plastic on stakes so that the cold has less of a chance of damaging the new sprout. This setup can be removed when the danger of frost has passed. Occasionally, Monk's-hood will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.

Why do I need to fertilize my Monk's-hood?

Fertilization is important to the Monk's-hood for several general reasons. Mainly, fertilization helps Monk's-hood and other plants by providing key nutrients that help the plant grow both above and below ground. However, the overall fertilization needs for a Monk's-hood are relatively low.

At times, a Monk's-hood may survive well without fertilization. However, annual fertilization is can be very beneficial to the Monk's-hood, as it will help keep the plant alive and may also encourage your Monk's-hood to create better flowers that last for longer. As such, those interested in helping their Monk's-hood look its best should keep up with annual fertilization.

When is the best time to fertilize my Monk's-hood?

The ideal time to fertilize a Monk's-hood is in the late winter to early spring. During that time, your Monk's-hood will be exiting its dormant phase and entering a phase of active growth. Fertilization at this time allows the plant to get off to a great start for the season by encouraging healthy growth.

While it is generally most advantageous to fertilize a Monk's-hood during the early spring, it is also permissible to fertilize a Monk's-hood during the fall too. However, summer and winter remain the seasons in which it is not a good idea to feed a Monk's-hood.

When should I avoid fertilizing my Monk's-hood?

You should not fertilize your Monk's-hood during any time of the year except during the late winter and early spring. The low fertilization needs of this plant allow a single annual feeding to suffice. Continuing to fertilize throughout spring, summer, and fall can easily lead to overfertilization and all of the complications that can come with it. The only exception is if you did not fertilize in spring, which means that it is permissible to feed this plant in fall.

Along with refraining from fertilizing for most of the growing season, there is also no reason to fertilize this plant during the winter. In winter, the Monk's-hood will be in a dormant growth phase, meaning that it does not put forth new growth. With that being the case, fertilization during most of the winter is not advisable.

What type of fertilizer does my Monk's-hood need?

Nearly any kind of general-purpose fertilizer with a balanced amount of the three main plant nutrients will work well for a Monk's-hood. However, there are a few specific nutrient blends that can be even more beneficial. For instance, many gardeners follow the belief that higher volumes of phosphorus make for stronger roots and better flowers. Since Monk's-hood is a flowering plant, applying a phosphorus-rich fertilizer may be the best approach.

You can use a fertilizer that comes in a granular form or a liquid form as long as there are plenty of nutrients present. Outside of manufactured fertilizers, you can also use more organic means to improve the soil for your Monk's-hood. Mainly, compost, manure, and similar materials can go a long way towards creating a healthy growing medium for your Monk's-hood.

How do I fertilize my Monk's-hood?

The most common way to fertilize a Monk's-hood is to apply a granular or pellet fertilizer to the soil around your plant. Remember that the ideal time to fertilize is as the plant is exiting its winter dormant growth phase and entering a phase of active growth. In early spring, wait until the plant begins to send shoots through the soil, and then apply your fertilizer.

Some people may choose to use a liquid fertilizer instead of a granular one. In that case, you should dilute the fertilizer with water before applying it. Regardless of whether you use granular or liquid fertilizer, it is always best to moisten the soil before, during, and after you apply fertilizer.

What happens if I fertilize my Monk's-hood too much?

As you care for your Monk's-hood, recall that this plant does not need a lot of fertilizer each year and will begin to suffer if it receives too much. Firstly, any overfertilized plant runs the risk of fertilizer burn, a condition in which excessive amounts of fertilizer draw nutrients and moisture out of the plant's roots, causing its decline.

Also, overfertilizing a Monk's-hood is also a way of weakening your plant and making disease far more likely. There is also a potential that overfertilization could cause your Monk's-hood to flower less or not at all, which is a significant detriment considering the blooms of this plant are what make it so valuable and sought after by so many gardeners.

Common Pests & Diseases

Common issues for Monk's-hood based on 10 million real cases

Wilting after blooming

Flowers may wither for a variety of reasons.

Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.

Leaf beetles

Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.

Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Yellow spot

Leaf spot can show up as yellow or white spots on the leaves.

Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.

Black spot

Infection by the black spot pathogen causes black spots or patches to appear on leaves.

Solutions: Some steps to take to address black spot include: Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves. Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash. Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil. Use a spreader in the fungicide spray to ensure better coverage.

Aphids

Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.

Solutions: Aphids can be controlled with physical, biological, and chemical methods. For less severe cases: Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants. Use a hose with a good stream of water to spray them off. Introduce beneficial insects such as ladybugs and lacewings. For severe cases: Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants. Remove and dispose of infected plants or plant parts. Surrounding plants should also be treated to fully control the problem.

Nutrient deficiencies

A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.

Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
