Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
How are geraniums maintained indoors?
Once the roots have established, new top growth appears. Rooting might take one to four weeks, depending on the type of plant, light, and temperature. To keep the pots from drying out if you set them in a south window with direct sunlight, you might wish to loosely cover them in a clear plastic bag. Yellowing leaves typically result from overwatering or too cold of a climate.
The plants in their original containers or the ones you brought inside from your outside beds will be substantially smaller once you have taken cuttings from them. Take out any dead branches, brown or yellow leaves, flowers, or flower buds. Place them in a warm, well-lit area with modest water. You might want to take another round of cuttings in late winter or early spring depending on your needs and those of your friends.
For them to grow and bloom indoors, they require at least four hours of daily direct sunlight at regular room temperature. While they are actively growing, water them sparingly, making sure the potting mix is moist but never waterlogged. Between waterings, let the top half inch of the soil dry out. When there are signs of growth, apply a diluted 20-20-20 soluble fertilizer every three to four weeks.
For many years, I’ve kept ‘Shone Helena,’ a magnificent salmon-pink geranium, in my sunroom, where it blooms for most of the winter.
How long do indoor geraniums last?
One of the most dependable types of garden flowers is the geranium (Pelargonium spp.). Around the world, they are grown as indoor plants, as garden annuals in USDA plant hardiness zones 2 through 8, and as perennials in zones 9 through 11. If given the right care, a common geranium can live for 40 years or longer. The most frequent causes of geranium death are overwatering or underwatering, insects or illness, and cold snaps. They might eventually grow long and unsightly, at which point they should either be replaced or removed.
Can geraniums blossom inside during the winter?
I DON’T WANT TO BE BURDENED WITH TIRED, OLD, MONSTER-SIZE PLANTS WHEN IT COMES TO OVERWINTERING GERANIUMS. Fresh, young, eager-to-grow geraniums that are manageable in size for the window garden’s ornamental purposes are what I’m after. Do you share my desire? Then allow me to precisely demonstrate how to prepare these common summer plants for interior winter splendor.
A suitable time to restore and propagate zonal and scented-leaved geraniums is in the middle of August or at least six weeks before the first anticipated frost. This provides the plants plenty of time to heal from root stress and for cut stems to develop roots before the major shift from the outside to the inside.
I’ve never had a problem with the restoration and propagation techniques listed below:
Cut the plant back to within an inch of its life, or to the point where the lowest leaves may be discovered, when working with a zonal geranium that has grown all summer (like “Puritan White” above). Be harsh here.
Your plant should resemble this once virtually all of the top growth has been removed.
Pull the geranium out of its pot next. Place one hand over the plant’s top, where it may support the soil and top growth, to do this in a “professional manner”. Invert the pot next, and while keeping the base in place with your other hand, strike the rim of the pot against a hard surface.
It’s likely that you’ll find the plant to be extremely root-bound. We’ll take care of this.
Slice the roots in thirds using a sharp knife. You should cut away roots in direct proportion to the amount of foliage that has vanished.
After that, cut vertically to cut through the dirt and roots as shown above. The objective is to be able to center the plant in its previous pot with a one-half to one-inch space between the dirt now present and the pot’s walls.
Now carefully examine your geranium. Do you notice any rotten or dead stems? Cut off these. Only three or four stems that exhibit signs of vitality are required.
Then fill the pot with additional potting soil until it reaches about halfway up the edges.
Put the plant in the pot’s center now. If centering appears to be unattainable, then remove more soil and roots to produce a rounded form.
Afterwards, secure it with a paintbrush, a Popsicle stick, or a plant label (as above).
When planted correctly, there should be a one-inch space for watering between the soil’s surface and the pot’s top.
Thoroughly soak the plant until extra moisture drains out of the drainage hole. Remove any soil that is adhering to the leaves by rinsing them.
That’s all, then! You now possess a freshly restored geranium that will bring you joy during the rest of the winter.
What should we deal with all the stems that we cut now? All right, each of these can develop into a new plant.
The stems should then be left alone for a few hours (or perhaps a few days) to allow the cut end to “callus,” or dry out. It is unlikely that a callused cut will decay.
Stipules, or the little flaps along the stem, should also be removed. These could decay in soggy ground.
There isn’t a picture for the following three steps because I don’t believe you need it: Take a 4-inch clay pot, and cover the drainage hole with a piece of shattered pottery. Then add a new mixture to the saucepan.
To a depth that roughly corresponds to the length of your cutting, press a pencil into the earth in the center.
And then, use your thumbs to firmly press the earth down. Or “thumb,” if you are working while holding a camera.
Just add a little more mixture and adjust the stem if, after pressing down, the soil level lowers more than an inch below the top of the pot.
Give the plant plenty of water (until excess drips through the drainage hole). Simply spray the leaves once or twice daily until roots grow if wilting symptoms appear. When new growth is visible, your cuttings will have taken root.
Place the plant outside in a well-lit but dim area. After the young plants have developed roots, you can move them to a location that gets half-day sun (or full-day sun in a window garden).
By the way, perfumed leafed geraniums can be propagated and restored using the same techniques. Unfortunately, they are becoming rarer by the day, therefore the only way to ensure that you will have them from year to year is to propagate them. My rose-scented “Lady Plymouth” is shown above. This variety’s leaves can be crushed and added to your bathwater. You can also prepare scented icing for cakes and cupcakes by steeping the leaves in full-fat milk.
You can view images of the scented-leaved and large-flowered geraniums I’ve used in my many winter window gardens throughout the years by visiting the houseplants category on this website. The lavender-pink “Americana” made a lovely sight in my music room window in December 2011.
America appears beautiful in my herb garden as well. It recently drew a hummingbird moth here.
Indoor Culture: Give your geraniums as much direct sunlight as an east or south window will allow for indoor success. While plants grown from cuttings often don’t set buds until the days become longer in February or March, restored plants can bloom as early as December. In February 2008, I grew zonal, scented-leaved, and fancy-leaved geraniums in the window of my library/den.
You don’t have an east or south window? Put the plants in front of some fluorescent lights. I can tell you that zonal geraniums will bloom in January virtually as well as they do in summer if they are illuminated for 16 hours each day.
Once the plants are established, I use a high-phosphorus, low-nitrogen plant food to promote flowering. One and a quarter teaspoons of formula per gallon of water are fed to the window garden test subjects. Due to their prolonged exposure to light, I raise the food for the window garden plants to one and a half teaspoons.
Well. I sincerely hope that this tutorial was at least somewhat helpful to you. Maybe you’ll tell me by posting a remark. Your words are the light of my life as always.
How are geraniums maintained indoors during the winter?
Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mold.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shriveled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Can I keep my geraniums potted up all winter?
Geraniums can be overwintered inside in three different ways: as a houseplant, as a dormant bare root, or as cuttings. Your decision will be influenced by the amount of room you have indoors and the range of temperatures you can tolerate. Here is a closer examination of each method.
Overwintering geraniums as houseplants
If you want to keep the entire potted plant and have lots of room close to a window that gets bright, direct light, go with this option. A drafty west-facing window would be the ideal place for your potted geranium to spend the winter because geraniums prefer it chilly (55 to 65 F is optimum).
Wash the foliage well with your hose and repot the plant in new potting soil to prevent bringing unwanted pests from outside. You might also use insecticidal soap, which is sold in most garden centers and hardware stores as well as online. Avoid taking the plant indoors if it shows any signs of pests or illness. Only strong plants have a chance of successfully overwintering indoors.
During the winter, keep the soil wet but not damp. No more humidity is required. If the stems begin to sag, pinch them back to keep the plant compact throughout the winter. When springtime comes around, you may start fertilizing once more and transfer the plant back outside as soon as the temperature reliably rises above 50 F.
Overwintering geraniums as dormant bare root plants
This is the most typical way to overwinter geraniums, but it won’t work unless you have a dark, dry place that stays around 50 degrees throughout the winter.
First, dig up your geranium before it freezes and shake the dirt off the roots. To stop mold from forming, let the plant sit and dry for a few days before storage. Before moving onto the following phase, the roots must be completely dry.
The roots should be kept in a dark, dry place that doesn’t get colder than 45 degrees throughout the winter. Geranium roots should be kept at a temperature of 50 F. You can keep them by doing:
- It has been customary for generations to hang the plants upside-down from the rafters;
- placing them on a shelf after wrapping them in newspaper or a paper bag;
- they were put in a cardboard box.
Step 3: Every month or so, look for mold, black leaves, or limp stems at the roots. Remove any plant or root components that are harmful. Most of the stems should endure the winter in good shape. Before re-storing them if they become too wilted, give them a good bath in water and let them air dry.
Step 4: Reviving your geraniums involves cleaning them up, pruning the stems back to healthy green growth, and replanting them in new potting soil about six weeks before your final frost date. Where the new roots will grow, bury the stems two nodes deep. When you notice fresh growth in one to two weeks, keep the plants somewhat dry; after that, keep the soil moist until the plants are big enough to replant outside.
Overwintering geraniums as cuttings
If your light windowsill area is limited or you are concerned that bringing in your entire potted plant would also attract unwanted bugs, this is a nice technique to try. Additionally, it’s a fantastic way to multiply your existing geraniums.
To trim plants, you’ll need:
- a cutting edge.
- Most hardware stores and garden centers sell rooting hormone, which is sold online.
- Use little terracotta or plastic pots, or recycle a clear takeaway container for roasted chicken.
- If you don’t eat chicken, use clear plastic bags to cover the pans.
How long do geraniums in pots last?
My geraniums are no longer blooming. I fed them, but it was ineffective. What’s the issue?
You might be feeding them too much. Pelargoniums, a genus of geraniums native to the Mediterranean, flourish in full sunlight and relatively infertile soil. Overfeeding can be the issue if you have a lot of foliage growth and the plants appear healthy. For a while, stop giving them food. But if your plants are becoming older and their stems are getting lanky, it might be time to propagate. Although they can live much longer, geraniums typically only bloom for two years on average before becoming woody and losing their blooming ability. Thankfully, geranium propagation is simple. Simply cut stem tips with at least two pairs of healthy leaves from a four-inch stem. Cut the stem at the lowest point, dunk it in hormone rooting powder, and then plant it in a mixture of half sand and half peat moss. In around three weeks, repot in ordinary soil after providing adequate watering and covering with plastic to assist preserve moisture. Sticking the cutting in water and letting it grow roots before potting is a simpler method.
