Dead-Heading Knock-Out Roses – Is it Necessary?

                                                                              

TheGardenLady received this question from Tracey.
 
The Knock-Out rose company says that it is not necessary to dead head the roses.  See here.

Deadheading means to remove dying flowers from a flowering plant. The reason for deadheading is to trick a plant into producing more flowers. Plants make flowers to make the seeds for reproduction and when there are seeds, the plant will stop producing flowers. Plants that don’t set seed will continue to bloom longer.  Most plants benefit from having their old, dying flowers removed but it is not necessary for Knock-Out roses that have been created to continue to bloom for much of the summer without any deadheading

The other reason for deadheading the flowers is to make the plant look neater. Though the Knock-Out rose petals fall off cleanly, TheGardenLady finds that the rose bush looks nicer when she dead-heads.  TheGardenLady only dead heads when lots of the flowers have fallen, like after a heavy rain.

So to answer Tracey’s question, No it is not necessary to dead head Knock-Out roses. Easy care is another advantage to raising this type of rose.

Something Bugging Your Marigolds?

                                                                            

TheGardenLady received this question from Joyce.

I love marigolds but am unable to keep them healthy. I have had the same problem in the past and gave up on them for a while. Now several years later the problem still persists. The foliage looks fine but the flowers and buds (all stages) are full of worms. They are about 1/8-1/4 inch size, vary from brown to beige in color and leave behind a sawdust-like residue on the flower. They burrow into the seed pod and even flowers that look unaffected have the critters inside. None of my other annuals are affected. They are all grown in containers on a balcony. Any thoughts and any treatment suggested would be welcome.

Marigolds, Latin name Tagetes, are usually one of the easiest annual flowers to raise because they have so few pest problems. In fact, they are often used to prevent problems for other plants because they get rid of nematodes in the soil. They are used as companion plants.   See here.  

But like most plants, Marigolds like to have their environment just as it was in their place of origin. Marigolds, in spite of some of their names, originated in Mexico and Central America. There they had lots of sun and not too rich soil. Marigolds, if raised in an area where they do not get the conditions they want are more susceptible to problems.  See here.

Hosta Flowers

                                                                        

TheGardenLady received this question from Anne.

My row of hostas is at the edge of a wooded area and don’t seem to have many flowers.  We live in the Midwest and I am wondering when flowering should occur and how to promote flowers.

Though Hostas like to be in shade, just like most flowering plants, with more light and even some sun, hostas will bloom more. If you know the type of hosta you have, you might check on its flowering ability. It is a possibility that your hostas don’t flower very much. There are many hostas out there yet much work is being done on hybridizing newer and better hostas. One of the improvements being worked on is better flowering.  See here.

Mother-in-Law Plant

                                                                        

TheGardenLady received this question from Beverly.

I have a mother-in-law plant that has funny looking flowers that came up. It is sweet smelling. But it attracts wasps!! i have never heard or seen one bloom. Can you tell me where I can see a picture of the flower ?

Congratulations on your Sansevieria’s (mother-in-law’s tongue plant’s) blooming. You are treating your plant well to have it bloom.  A website that shows the flower is this.

The flower has so much nectar and sweetness, I would imagine that it would attract bees or wasps. I kept my plant indoors when it was in bloom so that my house benefited from the fragrance and no insect came near the flower.

Caring for Marigolds

                                                                          

TheGardenLady received this question from Sammy.

I am trying to grow marigolds on my balcony. They were already partially grown when I got them and were already flowering now they are starting to get lots of  flowers and the leaves are starting to fall off. I need some advice on pruning  them. Is there anything else I need to do to care for them? Also I kept one of the  dead flowers that fell off because I was told they hold the seeds of the plant that I can then replant.  Is there anything special I need to do before I plant  them.

Some people think that the marigold is the easiest flower to raise.  See here.   However, that being said, they do need lots of sunshine – the more the better. Marigolds like continuously warm or hot weather – not cold and hot weather – after all most of the marigolds we have in the US come from Mexico. They like to be watered but don’t like to be over watered – water twice a week in dry times. Too much rain can be bad for them so be sure the pots have good drainage. And though marigolds generally don’t seem to have many problems, they can have problems.  See here.  Your leaves falling off may be a sign that something is wrong.

Rhododendron Blues

                                                                     

TheGardenLady received this question from Abe:

I have this Rhododendron in my front yard that is not blooming, and seems sick, and I don’t know why.  My neighbor says that it has a fungus on it.  Do you have any ideas about how to cure an unhealthy rhododendron? 

There are many good sites on the web that talk about typical rhododendron problems.  Here’s one good site about  rhododendron problems that might be of help.

However the best way to find out what is happening to your rhododendron is to take in a good sized sample of your rhododendron WITH the dying parts of the plant to your local Master Gardener Extension office to have your specific problem identified. The MGs will tell you if your problem is a typical problem and if it is, how to handle it. They will recommend solutions. The MGs prefer a non chemical solution. Without seeing a sample, TheGardenLady can just guess what is wrong.

Romeo and Juliet Pansies

                                                                        

TheGardenLady received this queston from Samantha.

How do you grow (Romeo & Juliet mixed color) pansies? Are they a shade pansy?

Plant these fragrant pansies in the  Autumn/Winter.  They like cool weather to bloom. They hate hot weather.  In cool weather they will give you two seasons of bloom – first in the fall and then again in late winter.

They have high Frost tolerance- +++ (high)

Position them in full sun to part shade

Usage: Ideal for bedding, borders, rockeries and containers

Available as: seedlings

A good link that tells about planting Romeo and Juliet pansy seeds is this.

Window Gardens – Planting in Windowboxes and Containers

                                                                            

TheGardenLady received this question from Karen. 

I am planning on moving to Florida this year, and I would really love to grow a window garden in the warm weather.  Coming from Alaska and having no prior experience with gardens, I’m not really sure where to start.  What kind of window boxes are available that are low-cost?  Are window gardens really high maintainance?  What sort of flowers should I choose that will thrive in Florida’s enviroment?  

Welcome to the East Coast. After the short growing season of Alaska you may think you have arrived in flower heaven when you reach Florida. After all Spanish explorer Ponce de Leon who  first saw Florida on Palm Sunday, April 2, 1513 thought he had so he named the state “Pascua de Florida,” meaning “Feast of Flowers.”  The state has a nickname that is The Sunshine State.  Sunshine is great for growing flowers. However the state  has unique growing environments.

Caring for Daffodils

Fran asks TheGardenlady the following question:

My mother gave me a (small) pot of gorgeous and very leggy daffodils to take to my office. They have really brightened up my desk, but I am worried that I might have killed them. A few leaves are turning yellow/brown at the tip, and several new flower buds did not bloom, but turned brown and shriveled. I have been good about watering the plant and caring for it. Does it want more sunlight? Do office environments generally kill flowers like daffodils? Thank
you so much for any help you can give!                                                 

Not knowing about the culture of the bulbs before they were brought to you, nor seeing the plant’s condition, I cannot say much about the cause of their dying in your office.  Bulbs that were forced needed good, fertile soil as well as fertilizer in the soil when they were starting to send up shoots in order to have healthy flowers.

When the bulbs are in flower indoors they need a lot of  bright light, some say sunny spot or artificial lights to grow  properly and not leggy.  Office lights can be good for flowers if they are close enough to give light during the day and are shut off at night. Daffodils don’t want light 24 hours.

Growing Roses in the Garden

Joe asks TheGardenLady the following question:

I would like to try to grow roses in my garden. I’ve heard some varieties are very difficult to grow. Can you recommend a variety that is fairly easy and what suggestions you may have to make them look their best?                                                    

Many roses are high maintenance. They generally want a minimum of 6 hours of sunlight. They like nice loamy soil – use your compost for best results. Roses want water, but the soil should have good drainage. And to avoid diseases, try not to do overhead watering. Water the roots not the leaves.  Roses like to be fed nutrients that might be missing in the soil. Roses get diseases – they like good air circulation, need pruning and need spraying for diseases. They attract insects like the Japanese beetle. And deer love to eat roses in spite of their thorns.
