Selecting the appropriate-sized planter for your hydrangea is the first step in planting. Because their roots are vigorous and quickly fill smaller containers, hydrangeas do not grow well in smaller containers. Additionally, smaller containers dry out far too quickly for hydrangeas. Generally speaking, we advise purchasing a medium to big planter that is at least 2 feet wide.
Make sure there are drainage holes at the bottom of the planter once you’ve chosen it. It is necessary for hydrangeas to be grown in pots because they will decay if the soil lacks adequate drainage. To aid in drainage, we also like to add a layer of rocks at the bottom. The most important stage for healthy plants is proper drainage.
You must then purchase soil made especially for planters. In containers, topsoil can occasionally fail to drain properly. Compost can be applied to the soil to provide additional nutrients.
Plant the hydrangea at the same depth in the soil as it was in the pot it was previously growing in when putting it in the pot. To water the planter without the water washing out the top, leave at least 2 inches between the top of the soil and the top of the planter. To assist the plant stay firmly in the pot, gently press down on the dirt around it to remove any air pockets.
How is a potted hydrangea maintained?
If you’ve ever received a hydrangea in a foil-wrapped pot, you likely loved it for a few of weeks before seeing it sadly wilt. You might conclude from it that hydrangeas are poor container plants.
Most hydrangeas that are given in pots as gifts do poorly because they are kept indoors for too long. Others perish because they were grown in a greenhouse and are not cold hardy in your region of the country, even if they are planted outside.
However, hydrangeas can make wonderful potted plants if you choose wisely. What you should know is as follows.
Potted Hydrangea
You can utilize hydrangeas in containers in your garden on stands, decks, or patios. This plant looks classy perched atop an antique column.
- Choose a location for the hydrangeas first. You may move them around, which is one of the benefits of growing them in pots. This also makes it simpler to provide hydrangeas with the ideal growing circumstances because many of them like morning sun and afternoon shade. Additionally, you can arrange them to beautify a patio or other area for a celebration or special event.
- If your pots won’t stay in the same spot all the time, search for containers with wheels on the bottom or think about durable, rolling plant stands. Don’t forget that after adding dirt and plants, containers can become rather heavy, and soaking them can make them even heavier.
- For your hydrangea, pick a large container with a diameter of at least 18 to 20 inches. The plant commonly wilts in small pots like the one your gift hydrangea arrived in since they typically dry out too quickly. Drill drainage holes into the bottom of your container if there aren’t any already. Rotting can result from water that accumulates around the roots.
- Next, pick a variety that is advised for your area. (This is a general guideline for growing any plant well.) To choose the best types for your yard, read plant tags or conduct online study. Some hydrangea varieties can grow in USDA zones 3 and 9, while the majority are hardy in zones 4 to 8.
- Although using miniature hydrangeas in pots isn’t required, you might wish to if you have a small yard. Not only do hydrangeas grow tall, but they also become bushy. If not, prepare to prune your plants as they develop. Be careful when conducting your research; see if your variety blooms on new or old wood. You’ll lose the flowers for the following year if you prune at the incorrect time of year.
- Use high-quality potting soil that contains organic materials rather than regular garden soil. If you want the hydrangea to continue growing, don’t plant it higher or deeper than it was in the pot it came in. Make sure there is space below the pot’s rim so you can water.
- To get rid of air pockets, gently compact the dirt close to the roots.
- Water your hydrangea well whenever the top inch or so of the potting soil feels dry. But being underwater is preferable to being overwatered. When they are thirsty, hydrangeas may wilt to let you know. However, this can stress them out, so check them every other day or so. You’ll eventually get a sense for how frequently to water. In times of drought or extreme heat, you might need to increase your watering.
- Although hydrangeas don’t require a lot of fertilizer, you can feed your plants once or twice a year with a commercially available composted manure, a 10-10-10 granular fertilizer, or a slow-release balanced fertilizer. If you reside in a warm environment, wait until after July or August to fertilize. Gardeners in the north can get away with applying fertilizer just once, in June or July. Feeding hydrangeas later, when they should be starting to go dormant for the winter, promotes fragile, fresh growth.
- If your plant already appears to be ill or unhealthy, don’t fertilize it—you’ll just increase its stress. Try to solve the issue instead.
Can hydrangeas in containers endure the winter?
Hydrangeas in potsWinter Care Bring potted plants indoors before the first frost for the greatest hydrangea winter protection. They can stay outside and be protected by covering the entire pot and plant if they are too heavy to transport.
How long do hydrangeas in pots survive?
When hydrangeas outgrow their pot, they must be repotted in order to maintain their health. This often occurs every one to two years.
Once it has done flowering in the fall, carefully remove yours from the container it is now in. Make sure the new garden planter has drainage holes and is about an inch bigger in diameter than the old one. Plant it at the same depth as before.
Can I put my hydrangea plant in a pot outside?
Mophead hydrangeas can be cultivated outside wherever the wintertime temperature stays above -15oC because they are hardy (5oF). However, as they were grown in greenhouses and given fertilizer to induce early flowering, potted hydrangeas sold as houseplants may require some time to acclimate to life outside before being put out. Place them outside in their pots during the day and bring them inside at night to harden them off for one to two weeks before to planting. Hydrangeas that have been grown for outdoor planting can be planted immediately. Mid- to late April, when the soil has had time to warm up, is the ideal time to plant mophead hydrangeas outdoors.
The optimal conditions for hydrangeas are shade from the sweltering afternoon sun and moist, well-drained soil. They are therefore excellent alternatives for shady gardens, and in mid- and late-summer, their dramatic spherical flowerheads are absolutely gorgeous. Regularly water hydrangeas, especially during dry spells, and in the spring or fall, mulch with compost or other organic material.
Because of the soil’s pH (acidity or alkalinity), pink and blue mophead hydrangea blossoms have the unusual ability to change color. The blossoms will be a deeper shade of blue the more acidic the environment is. Flowers turn a gorgeous pink on alkaline soil. The color of white mophead hydrangeas doesn’t alter.
Will hydrangeas in pots return every year?
Hydrangeas produce beautiful, vividly colored blossoms on globe-shaped flower heads, and they are frequently presented as gifts during the spring holidays. The United States National Arboretum claims that Hydrangea macrophylla is the most widely cultivated species in the country. Hydrangeas make excellent indoor plants and may be grown outdoors in U.S. Department of Agriculture zones 6 through 8. If you received a potted hydrangea as a present, it was probably already in bloom. After the petals first fade, many people throw away their hydrangeas, but with the right care, the plant will bloom once more.
Why are the hydrangeas in my pots dying?
A hydrangea’s roots can be burned if too much fertilizer is used, which will likely result in the plant dying, turning brown, and drooping.
As such, hydrangeas are not heavy feeders and do not require annual feeding in the same manner as roses do, and doing so can actually be detrimental.
Hydrangeas frequently develop and flower to their full potential if they are planted in healthy soil or the soil has been modified with compost prior to planting.
The hydrangea should flourish if a 1-inch-thick layer of mulch is applied around it to assist retain moisture and supply nutrients to the soil (compost and leaf mould are ideal options).
Only in the following circumstances should fertilizer be used:
- Planting the hydrangea in sandy soil (which is nutrient poor).
- The hydrangea is in a pot or other container where the roots have used up all the nutrients in the soil.
In these two situations, it is recommended to use an all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) that is applied once in the spring and is generally well-balanced.
The roots of your hydrangea can be burned by well-rotted manure, especially if it is added to the soil after planting. However, if the manure is made from poultry manure, it may contain a lot of nitrogen.
To prevent issues, I advise putting compost to the soil as a soil amendment (fresh manure is particularly harmful, always allow it to rot for a year or so before using manure on your garden).
If your hydrangea is exhibiting indications of stress as a result of being recently planted in soil that has been altered with manure, move it to a location with soil and compost, and it should recover.
Reduce the amount of fertilizer used and remove any discolored leaves or blossoms. To assist the hydrangea recover, thoroughly water it in an effort to dilute the soil’s water-soluble nitrogen.
Key Takeaways:
- Most frequently, hydrangea deaths are caused by the soil’s lack of moisture. Because they need their soil to be continually moist, hydrangeas will droop or even die in a dry environment.
- Drought, transplant shock, frost damage, and too much sun can all cause hydrangeas to perish.
- If the pot base doesn’t have drainage holes, potted hydrangeas may succumb to root rot. Small containers may dry out too rapidly and limit root expansion.
- Water hydrangeas liberally, cover them with compost mulch, and keep them out of the sun and wind to help them recover. To encourage healthy growth, remove any growth that has been sunburned or damaged by frost.
What is the ideal location to plant hydrangeas?
Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.
When should I plant hydrangeas?
The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.
Locations to plant hydrangeas
The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.
hydrangea-friendly soil
The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.
Methods for planting hydrangeas
Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.
The best way to grow hydrangeas
Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:
- Close to your hydrangea plant, make a tiny trench.
- Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
- Where the branch meets the trench soil, make scuff marks on the bark.
- After the trench is filled, cover it with a paver, brick, or stone.
- The branch can be transplanted to a different area once it has established its own root system over time.
Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.
Are hydrangeas grown indoors and outside different from one another?
Remove any foil wrapping from the hydrangea if it was a gift. Remember that hydrangeas offered for sale around the holidays might not be hardy enough to endure indoors. If you’re serious about growing hydrangeas indoors, your chances of success may be higher if you buy them from a nursery or greenhouse.
Place the hydrangea in a sizable pot filled with superior potting soil. Put the plant in an area with lots of light. Hydrangeas planted outside can take some mild shadow, but interior plants require lots of light (but not intense, direct sunlight).
When the plant is blooming, give your potted hydrangea indoor plant periodic waterings, being cautious not to overwater. After blooming, reduce watering but never let the potting soil go completely dry. If at all feasible, use distilled water or rainwater to hydrate potted hydrangea houseplants because tap water frequently contains chlorine and other pollutants.
If the air inside is dry, use a humidifier or put the plant on a humidity tray. Particularly when flowering, hydrangea thrive in a cool environment with temperatures between 50 and 60 degrees F (10 and 16 degrees C). The environment is probably too warm if the leaves start to get brown and crunchy around the edges.
Keep heat sources and drafts away from the plant. While the plant is blooming, feed it once a week with a water-soluble fertilizer that has been diluted to half strength. After that, limit feedings to to one monthly.
It is advised to give hydrangeas a time of hibernation in the fall and winter when growing them as houseplants. Place the plant in a room that isn’t heated and is about 45 degrees Fahrenheit warmer (7 C.). To keep the plant from wilting, the potting mixture should be kept on the dry side but only lightly watered when necessary.
