Blooming Problems With Knock Out Roses

Gotta love those knock-outs!!! by perennialpal
Gotta love those knock-outs!!! by perennialpal

TheGardenLady received these two questions about Knock Out roses from Mary and Diane respectively.

I planted eight knock out roses in the sun last year and they bloomed. After blooming the first year I put mulch on the base of the rose bush and the ground was not frozen. This spring I cut them back slightly the first bloom was great. We went on vacation and had a bad rain storm and the roses stopped. What am I doing wrong?

Last Spring (2008) I planted 9 knock-out roses. They grew and bloomed fairly uniformly. This Spring they looked very healthy, and all burst into bloom at the same time. After the first bloom, two of them turned a very light green.  I have checked them for over/under watering. Fertilizing is not an issue as I have fertilized them all uniformly. The other 7 are beginning to bloom for the second time, but these two do not have new buds. They do not look like they are ready to die.  I can find no evidence of insect damage either at the root or leaf level. They are all planted in the same bed in one grouping for concentrated color (i.e. within feet of each other).  I am stumped as to what to do. Any ideas?

TheGardenLady imagines that you must have a fantastic show of concentrated color with those beds Knock Out Roses. TheGardenLady has just two Knock Out Roses and the floral show is amazing.

Two questions that are similar but not the same; however the treatment of the roses should be the same.

The first lady had Knock Out roses that stopped blooming after heavy rains knocked off the flowers and haven’t started reblooming.

The second lady has some of her Knock Out roses in one bed that are not blooming.

One Sunday in May TheGardenLady was invited to lunch at Lacroix
Restaurant
in the Rittenhouse Hotel on Rittenhouse Square. The restaurant advertises itself as having one of the 10 best hotel brunches in the US. TheGardenLady will not talk about the wonderful ambiance of the restaurant or the fantastic service we had that day nor the marvelous food both in the presentation and taste. It was an amazing experience that
TheGardenLady was happy to have once in her life. Still as nice as all that was, that is not what made TheGardenLady want to write about the experience. TheGardenLady is interested in plants. And on the table were some unusual floral pieces that I think warrant a post.

First decorating the table was a cache pot filled with fraises du bois ( I have seen it also written fraises des bois). Fraises des Bois is translated as strawberries of the woods or wild strawberries. Growing up in the country, TheGardenLady couldn’t wait for spring and early summer to look for wild strawberries, the native American wild strawberry, Fragaria vesca var. americana, which grows in spring in the fields or in patches along the roadside or near the woods of the eastern states. These wild strawberries were tiny and delicate with an intense strawberry flavor. They were ambrosial.

TheGardenLady thinks her mind doesn’t deceive her when she recalls finding some in the Black Forest in Germany.

Then when TheGardenLady moved to the town where she presently lives,
she found there were patches where the wild strawberries grew. This was so wonderful and she delighted finding berries in these spots she kept secret. But then the street crews mowed the green along the sides of the road, mowed the areas where the strawberries grew. And they mowed so often that these wild patches gave up the ghost. The strawberry patches are no longer alive.

Several varieties of this wild berry have been growing in forests all over the world since prehistoric times, and though I once read that the French have domesticated them, I have never tasted the domesticated wild strawberry; but have been told that even the French have never succeeded in breeding a strawberry that compares to its wild cousin when it comes to taste.

Mojave Desert Wildflowers

In a departure from the man-made gardens that are often the subject of this blog, this past weekend’s adventure was spent exploring the wildflower displays at two unique spots within the Mojave Desert (see here). Covering southern Nevada, western Arizona, southwestern Utah, and southeastern California, this roughly 25,000 square-mile-large swatch of land is home to hundreds of species of plants; many of which produce springtime blossoms of white, yellow, orange, red, lavender, purple, and blue.

Separated by almost 200 miles, the two unique spots included the southernmost and westernmost tips of the Mojave Desert; respectively in Joshua Tree National Park and the Antelope Valley California Poppy Reserve-both in Southern California. While the blossoms on the two parks’ namesakes-the Joshua tree (Yucca brevifolia) and California poppy (Eschscholzia californica)-were an obvious motive behind picking the locations, numerous other blossoming species also inhabit these regions.

The first stop of the adventure, Joshua Tree National Park (see here), technically spans two deserts: above 3,000 feet and on the west side of the Park is the Mojave Desert, and below on the east side is the Colorado Desert, which is part of the larger Sonoran Desert. On the border, between the two deserts, lies the Lost Palms Oasis Trail; a favorite among hikers eager to see springtime wildflower blossoms. The 7.5 mile hike takes you from the Cottonwood Spring Oasis to the Lost Palms Oasis and back. With the right amount of fall and winter rains, and warm enough springtime temperatures, the typically parched, rocky, and sandy landscape between the two oases is transformed with patches of color.

This early-April weekend, at least 20 different blossoming species were on display along the Lost Palms Oasis Trail. Most prevalent were the yellows of the Creosote Bush (Larrea tridentata), Desert Dandelion (Malacothrix californica), and Brittlebush (Encelia farinosa). Moreover, on the way to the trailhead, when driving from the north end of the Park to the south end, a wonderful highlight was the fields full of Desert Dandelion on both sides of Pinto Basin Road.

Saving Potted Daffodils

TheGardenLady received this question from Cecilia.

I have some daffodils in pots and the flowers have already dried out. What do I need to do  to keep them healthy for next year? Or will theybe fine without my help?

When the flowers on your daffodils dry out, cut them off. This goes for daffodils growing outdoors, too. But NEVER cut off the leaves. After flowering the leaves continue to provide nutrients to the bulb. By cutting the flowers off you prevent the daffodil from setting seed. Unless you are a professional daffodil breeder or an avid amateur, daffodil seeds are more difficult to work with so you don’t want the plant to set seed. You want all the energy and growth to go into the bulb for next year’s bloom.

Now with potted daffodils, because the plant was forced- the bulb may no longer be any good. But you can try to save it and hope it is still ok. The daffodil you bought came in a small pot with limited soil which was depleted of nutrients when it was forced and bloomed. So even though the fall is the best time to plant daffodil bulbs, TheGardenLady would immediately plant the flowerless bulbs into the ground with the leaves still on. This way the bulbs may have a chance of living by getting some nutrients from the leaves as  well as from the outdoor soil. Mark where you planted the bulbs after the leaves die, so that you know where to look next spring to see if you saved those daffodils. Remember, plants want to live so that if you give them a good chance, they might comply. But, if they die, you know you tried.

Good luck.

Caring for Sick Peace Lilies

TheGardenLady received this question from Linda.

I have a peace lily indoor plant which has sentimental value to me and over the past winter it has contracted a leaf condition – the leaves die from the tip towards the stem.  It’s as though a critter is “sucking” the life from it. It still flowers, but I am afraid as more and more leaves are infected I will lose the battle. Any suggestions?

TheGardenLady has to assume from your brief email that you have not changed anything in your plant’s environment- you haven’t moved your plant or changed the lighting, temperature, humidity or care. Usually most brown tips are caused by low humidity. And I also have to assume that you had not re-potted your Peace Lily Spathiphyllum improperly or put it in poor soil.

Or your Peace Lily might have to be re-potted. Sometimes a plant that has been in the same pot for a long time has a build up of salts in the soil from fertilizers and alkaline tap water. When you re-pot your plant, be sure you do not re-pot it too high or too low and use good potting soil (see here).

Caring for Indoor Daffodils

TheGardenLady received this question about daffodils:

I have also recently received a small pot of daffodils for indoors [probably from the local grocery store. It has the colored foil around it]. They doubled in length in one day, look healthy, and have smaller buds about to come out. I keep them in my room which is fairly cool and can get sunny. I’m wondering if I need to move the bulbs to a bigger pot at any point as well as if I can share the bulbs with friends once they stop flowering.

Daffodils like coolish indoor temperatures, 50-75°F, 10-24°C, the cooler the temperature, the longer the blooms last: medium humidity- too wet and you might get bulb rot: and bright indirect sunlight coming from the South/East/West

Do not waste your time repotting the daffodil bulbs for this season’s indoor flowering. Repotting causes stress on the plant which may cause the flowers to die.

The daffodils in the pot may have been forced (see here) to bloom at a specific time. Forcing is done by using special lighting techniques, fertilizing techniques and temperature control (see here). Enjoy the flowers by putting the little pot in a cache pot (see here) and bringing the entire thing to the room where you are entertaining for all to enjoy.

Dividing Dicentra Spectabilis

TheGardenLady received this question.

I have a huge Bleeding heart plant the I would like to divide. I see buds coming out about the size of a pinky nail. Is it too late to divide? I am afraid of killing it.

The correct time to divide Bleeding Heart, Dicentra spectabilis is in September. At that time the plant is going dormant. Now in the spring, the plant wants to send forth flowers and is putting its energy into flowering. You may not kill the plant which is fairly hardy, but you may prevent the Bleeding Heart from flowering this year. The fringed-leaf varieties divide nicely early in spring while they are emerging.

Read this about the Bleeding Heart plant.

Underwater Flower Arrangements

TheGardenLady received this question from Sally.

How would you condition daffodils that will be used in an underwater arrangement for 24 hrs? Once underwater, is there anything that can be added to stabilize the flowers?

TheGardenLady has never tried to make underwater arrangements and
wonder if the writer of this question is planning an underwater wedding with daffodils :-).  Sounds interesting.

I do hope the person asking this question is willing to do some experimentation before she attempts the underwater bouquet. The one thought TheGardenLady has, but has never tried, is to put the daffodils in a vase with a little glycerin with water in the vase, let it sit for a while and then put the daffodils underwater. A second experiment is to put some glycerin in the water you will be putting the daffodils under. Other stabilizing substances to try can be found on this website to see what works best for daffodils.

Please let TheGardenLady and her readers know your results. A photo
would be appreciated.

arrangements are here, here and here.

Galanthus – Snowdrops

Galanthus ‘S.Arnott’

Still looking forward to spring? Besides daffodils and crocuses there is another bulb that blooms early and is a harbinger of spring. It is a bulb native to Europe and Turkey that has a common name of Fair Maid of February because that is when many of the species bloom. In the US they are more commonly known as snowdrops.

Snowdrops are in the Galanthus family, a small family of about 20 species. Galanthus nivalis is the best-known and most widespread representative of this genus. And Galanthus nivalis S. Arnott seems to be the finest, sweetly honey scented, long lasting variety. Galanthus may be celebrated as a sign of spring, but an area blanketed with the flowers can look like there is still a field of snow in places where they are native or have been naturalised.

Galanthus ‘S.Arnott’ enjoying the sunshine

Because this flower is so beloved, in 2007 Scotland held its first Snowdrop Festival. In the UK and Ireland there are many gardens that open early just to showcase their snowdrops. Gardens such as: Brandy Mount, New Alresford, Hampshire, England which has the (NCCPG) National Plant Collection of Snowdrops or Primrose Hill, Lucan, County Dublin, Ireland or Cambo Estate, Fife, and Finlaystone, Renfrewshire both in Scotland.  In the US, this GardenLady’s favorite garden to see Galanthus in bloom with other early spring bulbs, is Winterthur in Deleware.

Galanthus grow in zones 3 through 9 though they do better in the cooler, Northern climates. Plant bulbs in early fall 2 to 4 inches apart and covered with 2 to 3inches of soil. All snowdrops prefer cool, moist conditions in the spring and a surprisingly dry summer dormancy in the shade which makes them good to plant under deciduous trees. Do NOT fertilize. The bulbs can be left undisturbed for years. But when you want to divide them, dig and divide soon after flowering and replant IMMEDIATELY so roots do not dry out. If you want you can plant seedlings which take 3 to 4 years to flower.

A great place to buy Galanthus bulbs is from Brent and Becky’s bulbs. The reason that this is a great place is that Brent and Becky’s dig and ship bulbs earlier than most places so that you know the bulbs are freshly dug allowing you to plant the bulbs really early in the fall to give them a good head start.

If you want to order Galanthus plants, TheGardenLady was told that they don’t ship well and there are only 2 places in the US to buy Galanthus in the plant stage. One place to buy the plants is from Carolyn’s Shade Garden at 325 S.  Roberts Rd in Bryn Mawr, PA 19010. But you have to go to her garden to pick up the plants. (TheGardenLady will soon be writing about Carolyn and her wonderful plants.)

Seeds seem to be trickier to buy. Most seed distributors seem to be in the UK.

Getting Cracker Jack Marigolds to Bloom for the Hindu Fire Walking Festival

TheGardenLady received this comment from Priven:

Every year I try to grow tons of cracker jack marigolds but they never seem to bloom well and do their best. I need a huge volume of flowers for the Hindu Fire Walking Festival, but still get let down at the last minute. What am I doing wrong? The Festival is on Good Friday towards the end of the South African Summer. Please advise.

It is difficult to determine your problems without seeing your plants. In the United States we have places we can take diseased or problem plants for the problem to be identified and hopefully corrected. These places are often part of the state agricultural extension office.

So let me give you a list of suggestions of things that could prevent the plants from blooming plus a suggestion to add flowers if all else is OK.
