Wish your life had a little more carefree beauty? Plant some geraniums, maybe. Geraniums are beautiful and low-maintenance plants that belong in planters, planting beds, and perennial borders.
Geraniums can be divided into two major groups. Zonal, fancy-leaf, ivy, perfumed, and Martha Washington (or regal) varieties of annual geraniums (Pelargonium species), which often only live for a year, are some examples. Perennial geraniums (Geranium species), which bloom continually from spring to summer, combine striking foliage with attractive blooms that emerge intermittently or continuously.
Where to Plant Geraniums
You must be aware of the type of geraniums you have in order to select the ideal planting location. With the exception of the ivy geranium, which thrives in mild shade, most annual geraniums require a location in full sun. On the other hand, depending on the variety, perennial geraniums can grow in either sunlight or shade. In the country’s southern and western regions, both types profit from shielding from the sun during the warmest time of the day.
What Kind of Soil to Use for Geraniums
Geraniums grow best in healthy, well-draining soil, which is ideal for both perennial and annual geraniums. Improve soil drainage and quality when growing geraniums in planting beds by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 to 8 inches of native soil. When growing geraniums in pots, Miracle-Gro Potting Mix should be used because it is light and fluffy. For the ideal planting medium, combine garden soil and potting soil in equal portions, or fill raised beds with Miracle-Gro Raised Bed Soil.
How to Plant Geraniums
Starting with young plants, such as the premium geraniums from the Miracle-Gro Brilliant Blooms collection*, is ideal (and simplest). Geraniums, both annual and perennial, benefit from warmth, so postpone planting in the spring until all risk of frost has passed. Once the summer heat subsides in the fall, you can also plant perennial geraniums. Try planting perennial geraniums from late fall to early spring in areas with mild winters.
Geraniums range in height from 4 to 48 inches tall and 6 to 36 inches wide, depending on the variety. For information on the recommended spacing for your type of geranium, consult plant tags. Use a pot that is at least 10 inches across for annual geraniums or at least 12 inches across for perennial geraniums when planting geraniums in pots.
Geraniums should be watered thoroughly after planting, giving the root ball and surrounding soil time to absorb the water.
How to Water Geraniums
Check the soil once a week for annual geraniums, and water when the top inch is dry. During their initial growth season, keep newly planted perennial geraniums in continuously moist soil. With the exception of periods of extreme drought, perennial geraniums can typically thrive on rainfall after they are established.
How to Mulch Geraniums
After planting geraniums, cover the area with a 2- to 3-inch layer of mulch to help keep the soil moist and to prevent weed growth and sun exposure. Use Scotts bagged mulch, chopped leaves, pine straw, or another material that is easily obtainable in your area.
How to Feed Geraniums
Your plants receive an excellent starting dosage of nutrients when you start with rich, nutrient-rich soil. However, you should also feed them frequently all season long for maximum results. Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food to your geraniums a month after planting to give them the extra boost of nutrition they require for magnificent blooms. Make sure you adhere to label directions.
How to Grow Perennial Geraniums
Even in the coldest climates, perennial geraniums don’t require particular care to survive the winter. After the initial flower flush, cutting perennial geraniums back by around one-third can encourage more blooms. Cut stems back as necessary if hardy geraniums like “Rozanne” or “Pink Penny” spread out too quickly and widely. These vining geraniums can have up to two-thirds of their length removed, and the plants will still grow back. To encourage new growth and prevent wilted leaves, prune cranesbill geraniums to 2 to 4 inches height after flowering.
How to Use Geraniums
Annual geraniums are excellent at stealing the show in planters and flowerbeds. Regal geraniums can resist cool weather and form lovely hanging basket plants, making them an obvious choice for planting in the early spring. Ivy geraniums are very stunning. Geraniums with aromatic leaves are strong in containers and form a lovely patio display where the leaves may be stroked and enjoyed.
In gardens with some shade, perennial geraniums add much-needed color and can thrive next to mature trees. While mid-size perennial geraniums go well with lanky shrubs, shorter perennial kinds create beautiful ground covers.

When may I plant geraniums in pots outside?
You should observe fresh growth in your geraniums 7 to 14 days after potting them up. Water sparingly and only when the soil dries out about an inch deep if you want this to succeed. The plants should resemble the one above after 4 to 6 weeks, at which point you can begin to harden them off for transplanting outside.
What degree of outside temperature can geraniums withstand?
Geranium plants cannot be subjected to frosts in order to be permanently evergreen, remaining alive with all of their leaves and stems. Frost on the leaves will kill them and make the leaves fall off. The stem will also die back if the frost gets into the tissues on it. Repeated frosts or extended exposure to below-freezing temperatures are not harmful, according to gardeners, unless the cold freezes the plant’s fleshy underground roots and its crown at the soil’s surface. When air temperatures dip and stay between 25 and 28 degrees Fahrenheit, plants can suffer significant damage or even die.
Can I plant geraniums outside yet?
Because they are not cold hardy below US Department of Agriculture plant hardiness zone 9 (San Diego Geranium Society), zonal, regal, and ivy geraniums (Pelargonium x hortorum, Iowa State University) are planted as annual garden flowers in many parts of the U.S. However, some gardeners in colder climates overwinter geraniums indoors and then replant them outside in the spring. When cared for in this manner, the common Pelargonium geranium varieties can live for many years.
where to grow geraniums
Geraniums don’t care too much about soil types, preferring it to be moist and well-drained like other plants, but once established, they may live in the rain shadow of buildings, shrubs, or trees.
when to plant geraniums
Geraniums can be planted in the spring, from March to May, to establish themselves before the heat of the summer and provide you with blooms all season. In order to give them time to create a strong root system and begin blooming for you in the spring, you may also plant in the autumn between September and October when the soil is still warm.
Geraniums can they withstand frost?
According to the University of Florida, one of my favorite container plants, geraniums, cannot withstand a cold. However, if they have had some time to acclimate to the chilly weather, they may endure a light frost.
I’m not sure if it switched from frost to freezing because I was away during that brutal cold snap in mid-December. It appears to have been below freezing, at least out here in the hinterlands west of State Road 7, based on what I heard about the temperatures.
But when I got home, my potted geraniums were the only thing in my yard that looked truly decent. The majority of them were covered in large, colorful flowers despite not being moved, covered, or even watered.
Another surprise was that the orchids, predominantly dendrobiums, that I have attached to trees received no particular care. When the weather went northerly, many spikes had buds, but now they are all in flower. Even though some of the flowers are not as spectacular as usual, they still seem good.
I suppose I’ll pay attention when I do my research in the future before planting a bunch of one kind of shrub and notice the warning “extremely cold sensitive.” When I positioned a dozen vibrant copper leaf shrubs across my back fence this past spring, I simply glossed over it. They went brown and crunchy after the first cold snap and quickly lost all of their leaves. I don’t really want a whole line of plants that will make me think of my Chicago yard in the winter every time the temperatures drop and then take the rest of the season to recover. However, after about a month there were a few tiny signs of life. They’ve left.
I intend to replace them with coco plum, a gorgeous native bush that creates a nice hedge, once I am confident that the worst of the bad weather is behind us. The coco plum has been described as “sensitive” in certain writings, but the majority of the study I did shows that once they are established, they are hardy. They appear to hold up reasonably well based on what I have seen so far this year. Definitely superior to both my copper leaf and my ficus, which was badly damaged.
How can I describe my ficus? They’re supposed to be recovering from the white fly infestations of the summer during this time of year, right? Sadly, it turns out that these plants, which were formerly thought to be indestructible, are also cold sensitive. They don’t seem to have ever looked this horrible to me. The weeds that snake through them and span the tops, which at least had the advantage of keeping them looking green most of the time, turned black from the cold, adding insult to injury. The 200 feet of ficus along the side of my property line was undoubtedly the worst gardening decision I made during my first year in South Florida.
Given that South Florida does not frequently experience this kind of weather, you might not anticipate native flora to handle it very well. But my geraniums are the only item that look better than mine because they have been such soldiers.
Is it too chilly to plant outdoors?
WBRC – BIRMINGHAM, Alabama Some of you may have already set your indoor houseplants outside, while others, like myself, haven’t done so.
After doing some research, I learned that houseplants need to be brought indoors as soon as the overnight low drops below 45 degrees. Temperatures below 40 degrees are harmful to the majority of tropical plants. Well, Thursday’s low 40s and Friday’s mid 40s are predicted as our temperatures. If we see a couple people in their upper 30s on Friday morning, I won’t be surprised.
If you place your indoor plants outside, you may wish to bring them inside or, like me, wait until May before thinking about doing so. While some are light, I have some large, heavy potted plants that I only want to move outside once until the late fall.
Most hanging or potted plants, such petunias, are safe as long as the temperature is above 39 degrees, and especially if it stays over the freezing point. I don’t anticipate any freezing temperatures over the next two weeks, but by Friday morning, some places north of I-20 may experience temps in the upper 30s. The majority of hardy annuals will be fine, so placing tropical plants outside would worry me more. For instance, peace lilies cannot endure chilly drafts or temperatures below 45 degrees.
Additionally, I would wait before planting tomato or pepper plants because they do not like temperatures below 55 degrees, or in some cases 50 degrees.
The average low temperature is 52 degrees, but during the next several weeks, we will occasionally dip below average, so I wouldn’t plant some crops, seeds, or delicate houseplants until May. Given that Boston Ferns can withstand sporadic blasts of cold air between 40 and 50 degrees, I did set them outside.
You can just Google it if you have any questions about your plants and if temperatures are too chilly for them.
How cold is 40 degrees for geraniums?
Can geranium plants be left outside all winter? If so, how should I handle them?
A: Tropical climates are where geraniums grow. If you lived in Los Angeles, you could leave them outside during the winter. Even though they can withstand temperatures as low as 40 degrees, they blacken and die right away when we experience hard freezes.
If you have space, you can bring the plant inside and preserve it as a houseplant to protect it from regrowth the next spring. Before we experience a harsh freeze, dig it up and cut the top back roughly in half. Put plants in a room that’s cool and well-lit. Winter is not the best time to expect any blossom.
or keep them: Trim the plant’s top growth by cutting back roughly half. Plant in a container that is just big enough for the roots. Place pots in boxes on their sides. The box used to store the pots should have a few inches of somewhat moist peat moss or sawdust in the bottom, followed by another layer of moist sawdust.
The goal is to keep the plants dormant rather than allowing them to flourish. The best location would be a garage that isn’t heated and doesn’t freeze. Don’t water; instead, simply check once a month to make sure the covering material hasn’t completely dried out.
Bring the plants outside into the light in the spring when the light is stronger, repot them, and remove any dead leaves. Your plants will sprout leaves and bloom once more.
Alternatively, you might take sturdy 4-inch cuttings, root them right away, and pot up the tiny plants, maintaining them as houseplants all winter. These options depend on how much space you have inside for geranium play.
In light of all their alternatives, many gardeners decide to buy new plants each spring and leave the growing to nurseries.
I have impatiens and daisies planted in planters on my deck. Which ones will endure the winter and do they require extra attention?
A: In regions of the country where the winters are not frosty, many of the plants that we grow as annuals in the Northwest are perennial. Depending on how resilient they are to the cold and the type of winter we have, certain species may thrive here.
Petunias, sweet Williams, Marguerite daisies, and other summer flowers frequently survive a moderate winter, especially if they receive some protection.
Place the containers next to the house so they can benefit from protection from the wind and potentially some heat radiation.
Compared to leaves and stems, plant roots are always more vulnerable to cold. Since the roots don’t have the insulation of a thick layer of soil, plants in pots are particularly at risk.
It will be beneficial if you can insulate your pots, boxes, and baskets in any way. In plastic trash bags, dry autumn leaves work wonderfully. Only partially fill the bags so you may shape them to fit your containers.
Apartment dwellers can accomplish the same task with newspaper or even styrofoam shipping “peanuts.”
You can choose to cover the tops of the container with some floating rowcover cloth as a final touch. It can be worn on all winter because it is light and “breathes.”
Use an old blanket, sheet, or piece of plastic. When temperatures are predicted to dip below 30 degrees Fahrenheit at night, any of these materials should be worn and taken off the following morning.
