Answer 1

What you've just described certainly sounds like the work done by a very damaging insect called the "Rose Midge" (Dasineura rhodophaga). Rose midges are tiny flies that lay their eggs inside the sepals of flower buds or on plant terminals. Hatching larvae move into flower buds to feed, leaving the injured buds to wither, blacken, and die.

Pupation occurs in the soil and two to four generations can occur annually.They are known to attack the buds and young shoots of roses and they'll suddenly turn black and die.

Since the "Rose Midge" can devastate commercially grown roses as well as those grown in gardens in your town, it's advised that you cut the infected portions off and take it immediately to your county Agricultural Commissioner for identification. They can advise you on how to get rid of this pest.

Answer 2

get specific rose food , with sestimic pesticide, so that it is treated for bugs and fed at the same time, also , we had lots of leaf drop here in vegas, i was told that we need to put the hose on dribble and let each large bush have an hour of water, that helps wash out the soil salts that build up when you water for 15 min a day, and it really did make a difference.

do this very important
Rose Care Basics:

Planting roses is one of the first activities of the gardening year. Planting early is important as roses need to have their roots well established. Often the tops will begin to grow before the roots have grown into their new location. Be prepared to water and watch them carefully through their first spring.

Roses Need:

* At least six hours of sunlight a day
* Soil that drains well
* Good air circulation
* To avoid hard freezes

When to Plant:

* Bare-root roses: Late winter is the best time plant bare-root roses.
* Container-grown roses: Early spring is the best time to set out plants grown in nursery containers (vs. bare-root, packaged types). Avoid summer planting unless you are willing to water every 1 to 2 days in hot weather.

How to Handle a Rose Before Planting:

* Soak the roots of a bare-root rose in a bucket of water for at least an hour or two. Overnight is okay, but no longer.
* Make sure the soil and roots of a container-grown rose are moist. If the soil is dry, water and let drain an hour or two before planting. Never plant a dry root ball. It is hard to re-wet.
* If you can’t plant your rose right away because the soil is not workable (too wet or frozen), store the plant in a cool place away from the wind, and keep the roots moist. A basement or garage is ideal. Or you can dig a small trench in a shady spot of your garden, lay the rose down at a thirty-degree angle, cover the roots with moistened soil, and cover the top with a layer of hay.

Preparing the Soil for Roses:

* Thoroughly mix soil amendments such as compost, peat moss, or rose planting mix in the planting bed. If you can’t amend the entire bed, amend in a circle of 3 to 4 feet for each rose.
* In spring, protect newly planted roses from insects by applying Bayer Advanced™ 2-In-1 Systemic Rose and Flower Care Ready-To-Use Granules to the soil. This guards against aphids, mites, and certain other insects that like new growth.

Look For This Information on the Rose Package:

* Plant Spacing: A five-foot spacing works well for hybrid teas. Larger plants will need more room. Antique roses vary tremendously in size and form.
* Follow planting directions on the rose label. Avoid planting too deeply. In the South, the crown of grafted plants should be about 2 inches above the soil line, even if the package doesn’t say so. Buried crowns invite disease in the South. The first lateral roots should be just at the soil surface. Set the plant in the hole so that the first roots are just below the surface.
* When the hole is filled to about an inch from the top, water thoroughly. This will eliminate any air pockets that might be around the roots. Wait for the water to drain. Then, finish filling the hole. With any remaining soil, make a rim around the edge of the hole so that water will funnel towards the roots.

Watering Roses:

* Water new plants regularly at first, applying about 1 inch per week. Drip irrigation is best to water slowly, thoroughly, and deeply without wetting foliage. Water less in winter.

Protecting Roses Against Insects:

If you have a problem with pests such as Japanese beetles, mites, aphids, and other pests that often reappear, you may protect roses by applying Bayer Advanced™ 2-in-1 Systemic Rose and Flower Care Ready-To-Use Granules. The best time to apply is just before the pests normally appear. Bayer Advanced™ 2-in-1 Systemic Rose and Flower Care continues to protect for up to 6 weeks after applying. Use this preventative strategy to help prevent damage on roses and other flowers.

Mulch:

* Mulch well with bark, compost, or pine straw.


Not only are green and flowering plants a great enhancement to any home or office decor, they are also beneficial to your health. The results of a study by the National Aeronautics and Space Administration (NASA) show that common houseplants are powerful, natural air cleaners - all the more reason why you want to keep your plants healthy with the proper care.

Most plants come with care instructions specified for the type of plant. The Society of American Florists provides these additional general guidelines to keep most green houseplants thriving:

Keep plants in medium-light locations - out of direct sunlight
Natural light is best, but some plants can also thrive in office fluorescent light. Most flowering potted plants should be placed in areas with the most light in order to maintain good flower color and promote the maximum number of flowers to open. Foliage plants will do well under lower light levels and can be placed in areas providing reduced light.

Plant soil should be kept moist at all times
Plants should not be allowed to dry out or wilt. Be careful to avoid overwatering - do not allow plants to stand in water. Avoid wetting plant leaves.

Avoid excessive heat or cold
Plants should be kept in a cool spot (between 65 to 72 degrees Fahrenheit) for best performance. They should be kept away from direct sunlight, heating or cooling vents, directly under ceiling fans, or on top of televisions or radiators. (Appliances like televisions give off heat, which causes plants to dehydrate.)
