These are caused by a bacterial ailment called leaf spot, which is frequent during the warm, rainy months. After removing damaged foliage, apply it with an Eco-fungicide or Liquid Copper fungicide.
Why are the leaves on my geraniums going brown?
A geranium plant’s brown leaves are frequently an indication of a fungus issue. A Pythium fungus assault at the roots, commonly known as water mold or root rot, is often the result of inadequate soil drainage. Additionally, this illness makes roots transform from white to gray or black. A Botrytis fungal infection causes browning on geranium leaves that first appears as a v-shaped portion of discolouration. As the disease worsens, fuzzy spores emerge and the leaves completely become brown.
What appearance do overwatered geraniums have?
Having too much moisture or overwatering is one of the most frequent reasons of yellowing leaves. Geraniums typically have yellow leaves at the bottom when they are overwatered. They could also get water patches that appear pale. If so, you should cease watering right away so that the plants can dry off. Remember that geraniums do not like excessive amounts of water and are drought-tolerant plants.
Geranium yellow leaves can also occur when the water or air are too cold. Since geraniums prefer warm climates, they struggle in cool climates. Geraniums with yellow leaves can be caused by prolonged cold weather, particularly cold, wet weather, or by cold snaps in the spring.
Additionally, a nutrient deficit could be the reason why the geranium leaves turn more yellow than green. Every third watering or once a month, geranium plants should be treated with a comprehensive, water-soluble fertilizer (ideally one with micronutrients). Geraniums’ yellow leaves can be avoided using fertilizer, and the plant will grow larger and produce more blooms as a result.
A geranium with yellow leaves sporadically indicates the presence of a disease. Verticillium, for instance, is a fungus that can result in stunted growth, withering, and brilliant yellow leaves.
What about the yellow-edged geranium leaves? Dehydration or a lack of water are frequently blamed for geranium leaves that have yellow margins or yellow tips. Geraniums require some water even though they can withstand drought. In these situations, you can use your fingers to feel the soil to gauge how dry the plants may be and water accordingly. Trimming the yellowing growth off might also be beneficial.
You can see that geraniums with yellow leaves often only require a little tender loving care in order to recover. If you provide a geranium with what it need, the leaves won’t turn yellow.
How can I bring back my geraniums?
Geraniums can live for the majority of the winter without soil, which sets them apart from most annual flowers. Due to their thick, succulent-like stems, geraniums may withstand prolonged periods of dryness if they are handled correctly to prevent illness.
How to Store Geraniums
- Before the first harsh cold of the season, remove the plant from its outdoor container and gently shake the soil from the roots.
- Reduce the plant by roughly 50%, taking care to remove any unhealthy-looking growths, flowers, or dead leaves.
- For the winter, pick a cool, dark spot, such as an unheated basement, garage, or shed. It is crucial that the temperature stay above 45 degrees F.
- The plant should be hung or put in paper bags. If you decide on using bags, don’t close them too tightly; you want some air to flow through them. When geraniums are overwintered, mold can grow on them. When hanging plants, The Spruce advises leaving enough space between them so that air can flow around them.
- Put tags (loosely) around the roots of your plants to identify them by color, or group them according to color while storing them.
Care for the Dormant Geraniums
- Take the plants out of the bags and give the roots a 1- to 2-hour soak in warm water. I’ve seen some professionals advise doing this once a month, while others advise doing it a few times during the winter. Before putting the plant back in the paper bag, give it time to completely dry. THIS IS ESSENTIAL.
- Even if the leaves are withering, check the geranium stems every two weeks to make sure they remain firm. You should discard any plants with withered stems right away. Anything with mold on it should be thrown away.
Reviving After Dormancy
- Trim any dead stem tips, and get rid of any roots that are too lengthy.
- Before potting, bare root plants can be given an extended soak in water to rehydrate the roots.
- Six weeks before the last frost, plant geraniums.
- When planting, bury the plant two leaf nodes deep in moist potting soil to encourage root development.
- Give them plenty of water.
- To reintroduce light and encourage fresh growth, place the newly planted geraniums in a sunny window. After inactive storage, it will probably take the plants 2-4 weeks before they begin to grow.
How are geranium leaves kept green?
The plants might not be getting enough nutrients. One or two times per month, apply a 20-20-20. Before adding water, sprinkle some Epsom salt around each pot. This may facilitate the plants’ uptake of nitrogen and promote the growth of chlorophyll.
Pale green or yellow leaves can be caused by both overwatering and underwatering. Make sure your containers have good drainage. Always keep the soil moist, but not drenched.
Eliminate the old, yellow foliage and faded blossoms. Give the plants some sun, but as the day grows hotter, give them some shade.
Must I remove the brown leaf tips?

We’ve experienced our fair share of brown, decaying leaves as we’ve learned how to properly care for various home plants over the years. We weren’t sure at first whether to take them out or leave them. Here is what we’ve discovered works the best.
Do you need to remove the dead leaves? Yes. Your indoor plants should have brown and withering leaves removed as quickly as possible, but only if they are more than 50% damaged. By removing these leaves, the plant looks better and the healthy foliage that is left can receive more nutrients.
Even though it might appear straightforward, there’s more to it than merely cutting those leaves off. To keep your plant healthy, you must assess how much of the leaf is dying and then carefully remove the damaged areas.
How frequently should geraniums be watered?
Generally speaking, water geraniums 12 times a week. However, geranium watering requirements can vary based on the environment, the weather, and other significant considerations. A zonal geranium will require more watering in the late summer than a perennial geranium will in the winter. Place your finger in the soil to determine when geraniums need watering. This method is the simplest and least expensive. It’s time to water if the top 2 inches (5 cm) of soil are dry.
- When the top 2 inches (5 cm) of soil feel dry to the touch, water geraniums.
- If you don’t want to get your hands dirty, you can measure the amount of moisture with a moisture meter.
Utilizing a soil moisture meter is another way to monitor soil moisture levels. To determine when your container geraniums require additional water, use this moisture meter. Before watering, wait until the needle is in the top end of the “dry region. Until the needle reaches the top of the “wet region,” add water. Keep it out of the “wet region.”
Do geraniums like shade or the sun?
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. Annual geraniums (Pelargonium species), which usually only last for a year, include zonal, fancy-leaf, ivy, scented, and Martha Washington (or regal) types. 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.
