Why are my lobelia turning brown

Lobelia is a perennial plant that is often considered an annual because growing conditions must be perfect for it to survive to rebloom another year. More than species of lobelia are grown as annuals, perennials or shrubs. The foliage and flowers are delicate, but lobelia flowers in abundance, blooming all summer right until frost. In spring and fall lobelias grow well in full sun. However, in summer the sun may be too strong for this plant and some shade will help keep it in bloom. A general rule of thumb when planting a hanging basket is to use one plant per inch of basket diameter - so 12 plants per 30cm 12 " hanging basket.

Plant spacing. Plant Lobelia Eezee Hanging Basket 12 22cm 9" basket 8 30cm 12" basket 12 30cm 12" patio container For details see Perennial Lobelia. Foliage: Tender forms have simple, green, alternate leaves.

Perennial forms have longer leaves in shades of green or purple. Type: Half- hardy perennial, usually grown in the UK as a half- hardy annual. Use clean shears and prune lobelia when the foliage is dry to prevent the spread of disease-causing fungal spores. Trailing lobelia varieties, such as those in hanging baskets, also benefit from cutting back. Cut these back far enough to remove the spent flowers but don't remove the hanging stems completely.

Bedding lobelia Bedding plants should be planted out at the end of May or early June, after the fear of any frosts. If you have a greenhouse or other protected growing area, you can plant up containers and hanging baskets earlier for the plants to grow on and so flower earlier, before putting outside in early summer.

Cut only pieces of new growth that have not yet flowered. Fill the clay pot with potting soil. Push cuttings into the wet soil.

Place your pot of cuttings in a shady area protected from wind and animal pests. Mist your cuttings twice a day with water. I try to trim them. The ones in the beds are mostly gone by end of July or mid August, though I saw some blooming today.

The ones in hanging flower pots are good until September. They can take some heat but do like water. I tend to think wintersown ones are tougher, if you want to try that. They are crazy easy to grow from seed. Not to worry It doesn't like hot weather Linda C. Mine do fine all summer long since I learned not to wet the foliage. I have also been spritzing my container plants with Daconil - it makes a BIG difference in foliage appearance. Hated red background and now hate the white. Don't hate me 'cause my house is ugly!

Please help me.. I hate this room! Help me hate this tile less. I, too, have had this problem for years with the standard blue lobelia. It starts out fine but dies by mid-summer. It is absolutely my favorite annual! However, I found a different variety about 2 summers ago, called "Big Blue".

It is a slightly larger plant with more of a trailing habit, but, otherwise looks pretty much the same It lasts much longer and usually lasts the entire summer for me.

Here in Connecticut, I can usually find it at my favorite nurseries, though, never at places like Lowe's or Home Depot. If you have a good local nursery, maybe you can ask them about it Around here, the hanging baskets of them are fairly popular as well. I've been growing the blue lobelia the past several years.

I've done different kinds of blues. Mine bloom until it frosts. Even thru our usually hot summers. It gets about 5 hrs of sun, but only from early morning until around noon.

I mulch it with cocoa bean mulch. They hate drying out. I water once a week. Our summers are quite often in the mid 80's to mid 90's. A few have been wet, but mostly I have to water once a week.

I do have them in a raised bed that drains well. But the mulch keeps the soil damp and cool. I don't trim them, they just keep on blooming.

By mid July they are draping really nice over the edge of the bed. The only things I can think of is keep them out of the afternoon sun and mulch them to keep the soil cool. It really doesn't like me either I think they like it shaded. Mine is a dark blue flower on dark foliage.

Them seem to like a lot of water. I don't see much annual lobelia at garden centers any more. I think a lot of people got tired of ripping it out as soon as the heat set in. Once I plant my annuals, I want them to last the summer. I gave up on it, too. Mimulus, pansies and violas present the same problem, but I sure love those plants.

Boy am I glad to see this post! As these pests feed, they damage the transport of tissue, causing the stems and leaves to slowly turn brown and eventually collapse. These pests may spread from one stem to another, causing further damage. When you suspect that your plants have been affected by corn earworms, cut out the affected areas, as it is unfortunately not possible to treat the larvae once they are inside the stem, but you could use a preventative spray of acephate around the base of the healthy stalks to prevent them becoming affected.

Some of the species of Lobelia plants are described as being annual as they are unable to cope with the harsh winter in some areas. These can survival all year round in warmer areas when certain requirements are met. There is no way that you can combat this problem except to be aware of how your local climate could affect the plant. Although these plants can be kept outdoors, they are unable to survive extreme conditions, and even when moved inside, there is no guarantee that these plants will be able to survive.

It is a good idea to trim these plants back during the cooler months when they start to struggle and place a cover over them, as this can prevent the plant from permanently dying. Brown plant tissue can be a problem that can cause a plant to die. When plant tissues have turned brown, regardless of whether it is a small or big leave, it can result in the death of the plant. Damaged tissues will mean that the cells are no longer able to receive nutrients through tissue transport, and this results in the plant wilting and collapsing.

There are many problems that can affect the transportation mechanism of a plant, but most commonly, it is due to incorrect watering. When you notice plant tissue turning brown, then check the plant for excess water or overly dry soil and for any signs of pests or fungus.

If you notice the cause of the problem, then you will have a better idea what you need to do to try and save the plant. During warmer weather, the leaves of Lobelia plants can become dried out, and in situations where dehydration is severe, the plant may become brown and die. Annual lobelia will grow nearly anywhere. Lobelia seeds can be sown directly in the garden or indoors for later transplanting. These plants typically require an area with full sun but will tolerate partial shade.

They also prefer moist, rich soil. Why do my hanging baskets keep dying? Too much water leads to root rot, while too little will leave the plant dehydrated. In both these cases, the plant will wilt and die.

Plants in baskets need to be watered more frequently than gardens. Why are my petunia hanging baskets dying? Water a Wave petunia only when the soil feels dry to the touch. You may be over- or underwatering your plant, causing the leaves to die back.

Container and hanging basket plants dry out more quickly than garden plants, but how quickly varies depending on light, wind and air temperature. How do you revive a petunia hanging basket? Examine the foliage of your petunia plants. If the leaves are limp and wilted, but remain green and pliable, watering may be all that is needed to revive them. Water them thoroughly until water runs freely through the bottom of the pot or, in the ground, until the soil is well soaked.
