I recently moved to Southern California and live ~8 blocks from the ocean.  I will be putting in the beginnings of my rose garden this winter.  I love 'Double Delight' and 'Betty Boop' and the 'Iceburgs'.  Will they do well in this climate?

Which HTs will do well?  Florabundas, Grandifloras?   Fragrance and disease resistance are at the top of my 'want' list.

Hi, Abbi, I'm Kim Rupert. While I live in the desert, I work two blocks from the beach and have five years experience with roses in this climate. What city do you live in? That can make a difference as some are hotter while others are colder. The two most common problems you'll experience in Coastal areas are Sawfly Larvae and mildew. If your micro climate gets sufficiently hot, you'll likely have rust and blackspot, too.

The Sawfly Larvae are the little green worms which skeletonize the rose (and other plants) foliage. They make the leaves look like Swiss Cheese. Mildew, you know. There ARE ways to successfully grow roses at the beach, though if you're used to more heat and less humidity, you have quite a bit to get used to.

You'll see MANY Iceberg roses all over. They are the most common, and one of the best roses ever created. Double Delight will grow there, and both it and Iceberg are best protected against the mildew you'll experience. Depending upon heat, both air temperature as well as reflected heat from walls, hardscape, etc., you may be able to control the mildew and most insects with horticultural oil. For hotter areas and times of the year, use Serenade. It's a bacterial, organic fungicide which has no ill effects with heat, and can be used on literally everything in your garden. For the Sawfly Larvae, Spinosad, or Monterey Garden Insect Spray is an organic, bacterial control. The chewing insects eat the bacteria, the bacteria eat the chewing insects. This is NOT the old BT, or Bacillus thurengenisis you may be used to. BT won't work on the Sawfly. Spinosad WILL.

As for other varieties which should perform well there, try to stay away from very fragrant red roses of any class. In general, they tend to require more heat and are less tolerant of higher humidity than many other types. Also, try to stay away from heavily petaled roses. The higher the petal count, the more heat required to form the bloom and make it open. Larger petals will tend to trap more of the water from the air (fog, humidity, sprinklers, etc.) and seal over, causing the blooms to rot, called "balling".

Do you have a preference as to what type of roses you grow? If you want Old Garden Roses, you'll probably have better luck with China, Tea, Noisette and Hybrd Musk types. In modern roses, Iceberg is tops, followed closely by several of the newer Hybrid Teas bred by Tom Carruth and introduced by Week's Roses. The lavender Neptune; pink Memorial Day; russet Hot Cocoa; violet Midnight Blue; and quite a few of his other roses are average to intensely fragrant and have very good health records over most of Southern California. I hope these pointers help you go in the right direction.

Hi Kim!!

Many thanks for you most informative answer.  I live in Encinitas and will be growing my roses in sandy loam next to a 6' fence for reflected heat.  I have never heard of the saw-fly.  I guess they don't live in northern California.  We did have mildews, rust, black spot and the nasty cucumber beetle.

Again, thank you!  Most helpful!

Hi, Abbi, you're welcome! You'll probably still have the cucumber beetle as well as Hoplea and Fuller Rose Beetles. You may want to make sure your roses are at least three feet from the walll. Even though it's "cool" there, the heat reflected and radiated from a wall can be extreme. Good luck! Kim

Hello Abbi, I garden 1 mile from sea in Hout Bay (Cape Town), S Africa. I am thinking of puting Cl Iceberg into my sheltered sunny courtyard, but have had difficulty with roses in this climate. I should be interested to know if you succeeded with your roses in your californian hideaway....Best wishes, Sholto.

Hi Sholto,
I have had excellent luck with the Icebergs, Betty Boop, Douple Delight, Rainbow Sorbet, Sunset Celebration, Hot Cocoa, and Silverado. My worst performing rose has been Mr. Lincoln (mildew and rust) and even though I love it dearly I'm going to get rid of it this winter. Good Luck with your roses. Abbi

Ive just moved from Norwich to Brockdish in the Waveney Valley on the Suffolk-Norfolk border. I too am wondering about the roses I have inherited, but am also trying to remind myself of your e mail address, Sholto - can you help?
