David Austin's English Roses (6)

Hybrid Tea Roses – up to 5′ tall

The most popular rose by far, providing a tremendous range of color, fragrance, form, and disease resistance. It is generally long stemmed with a single rose per stem.

Hybrid Teas are one of the most recognized and popular cut flowers. They are known for their long-stemmed elegance and high centered blooms. Their upright canes are more open than bushy and carry large flowers, hybrid tea roses boast a flower form that no other roses can touch! Born of a cross between the Tea Rose and Hybrid Perpetual rose, the Hybrid Tea Rose swiftly grew to prominence in the 20th century. This rose has an extensive colorful palette that allows for it’s vibrancy to be seen in the garden from a distance.

Pruning – Select the 5 to 7 most robust canes and remove all other to the point of origin. Prune the selected canes to 18-24” long.

English Roses

English Roses combine the delicate charm and fragrance of an Old Rose, with the wide color range and long flowering season of a Modern Rose.

English Rose, one of the newest races of roses, bred by David Austin. These combine the very large, densely petalled look and heavy scent of antique roses with modern virtues of smaller sized bushes and repeat bloom. Many grow as the Hybrid Teas, upright and shrubby, but a few, like ‘Graham Thomas’, grow to be very large. Sometimes growth is spindly the first couple of years, but eventually they form a strong plant.

Pruning – Most are thinned of crossing and weak growth. Then cut back the remaining canes by 1/3 of the total growth.

English Rose

Grandiflora Roses – up to 5′ tall

Grandiflora roses bear very large multiple roses at the ends of strong tall stems,  with clusters of hybrid-tea shaped blooms. Generally they have larger bloom and a much taller habit, with good disease resistance. Their long stems and classic rose form lend them well to cutting and using in arrangements.

Pruning – Prune like the hybrid teas, but leave selected canes at 24-36” long.

Climbing Roses – some reaching 20′ tall

Modern climbing roses are no more than very tall-growing versions of shrub roses. Most grow to about 6-12’ tall, and require tying and support. They will not twine around a post on their own. Climbing roses that are grown only vertically will produce flowers only on the tips of their growth, so for best flower production, train upward and then outward.

So how is a climber different from a rambler? Ramblers have smaller flowers that appear in larger clumps that bloom all at one time once a year. Climbers have larger flowers, but they appear in smaller groups and bloom repeatedly, as opposed to once a year.

Roses do best in full sun. While they tolerate some shade, they will bloom more and grow more dense and full when they receive at least 4-6 hours of direct sun each day. Also, pick a site that will accommodate the climber’s growth habit. Climbers can grow from 6-12 feet tall (even taller with some!) and spread almost as wide.

Climbers need little or no pruning the first two years. Many of the older climbing varieties tend to bloom on second-year canes. If it has been pruned back each year like hybrid teas and other shrub roses then bloom production will be minimal. Plan on pruning climbing roses every three or four years. At this time, remove small, twiggy canes and old, woody, less vigorous canes at the base of the plant in favor of the young, vigorous canes that are long and flexible. These can then be trained onto or through the structure provided.

Floribunda Roses – 2′ to 4′ tall

Floribunda rose is named for its production of large clusters of blooms on each branch. Easy to grow; provides continuous clusters of flowers on short stems, used for cutting and garden display. Often plants grow in a more shrubby round shape, these shrubs are ideal for rows and hedges. Disease resistance varies.

Pruning – Remove all twiggy and crossing growth. Shorten remaining canes to ½ the original length. Cut just above the nearest outward-facing bud.

Landscape Roses – 1′ to 3′ tall & 3′ to 5′ wide

These roses vary greatly in growth from ground cover roses to large shrub roses. Most require less maintenance than other types. Generally, they are marketed as disease resistant.

To be used as a summer flowering shrub in the landscape. There’s an easy solution for turning boring, underperforming areas in the garden or lawn into show areas. Spectacular, fast-growing roses and turn a spot into an area of beauty!

Miniature Roses – 1′ to 3′ tall

These are like smaller versions of Hybrid Tea Roses. They have mini flowers rather than a mini plant. Although, the plant size is generally in proportion to the flowers.

Miniature roses have been bred to stay under three feet tall while still putting out clusters of colorful blooms. This makes them ideal additions to rock gardens, tight border spots, the edges of rose gardens, and patio container gardens. The short bushes grow dense and bushy, vaunting packed trusses full of petite blooms! Maintenance-free nonstop summer-long color and hardy.

 The Blushing Knock Out Rose…

The Blushing Knock Out Rose produces an abundance of soft pink single flowers from April to frost on disease free plants. It is just as disease resistant as the famous original Knock Out Rose.

If you want truly disease-free and low maintenance roses, the Knock Out Roses are your rose!

The Knock Out Family of Roses are exceptionally easy to grow and do not require any special care. They are the most disease resistant roses on the market. They have stunning flower power with a generous bloom cycle (about every 5 weeks) that starts in spring and continues to beyond frost. All of the Knock Out roses are self cleaning so there’s no need to deadhead unless you want to.

All varieties of Knock Out Roses are winter hardy to USDA Zone 5 and heat tolerant throughout the entire U.S.. They thrive in almost every area of the country. In the coldest regions they will need winter protection.

Knock Out Roses can fit into any landscape. Plant them individual among other shrubs, in small to large groups, or as a low-maintenance hedge. Knock Out Roses hold up so well they are well-suited for use in foundation plantings as well.

Plant Knock Out Roses in locations that provide well-drained but moist soils and full sun to part shade. Morning sun is a must for all roses. Six or more hours of sun is best.

To keep your Knock Out Rose full and bushy from year to year prune the branches back to about 15-18 inches above the ground in late winter or early spring.

Growing Gorgeous Roses

Anyone can grow roses – all that’s needed is a spot with 6 hours of sun a day. Roses are even well suited to container growing, so you don’t have the excuse of no garden space!

step-1STEP 1

If planting bare root roses, first soak roots in lukewarm water for 12 to 24 hours. If you can’t plant your roses right away, you may leave them in their boxes for up to a week in a cool, dark place. Be sure to sprinkle roots with water every few days.

 

step-2STEP 2

Dig a hole about 12″ deep and 24″ wide. Make sure it’s large enough to give the plant’s root system plenty of room to develop after planting. Loosen the soil at the bottom and sides with your shovel.

step-3STEP 3

Fill the hole with water. It should drain in one hour. If the water remains longer, dig deeper to improve the drainage – or mound your soil and plant the rose in a raised bed.

 

 

step-4STEP 4

Build a mound in the center of the hole to support roots. Set rose on top, making sure the crown (the point where the canes join together at the shank) is at ground level, or a little lower in cold climates.

step-5STEP 5

Fill the hole with two thirds of the remaining soil mixed with peat moss or compost. Tamp down gently with your hands. Add water, let it soak in, then finish filling the hole with soil. Tamp down lightly and water well.

 

 

step-6STEP 6

Spread mulch, compost or bark chips around the plant to suppress weed growth and help retain moisture. Water 3 to 4 times a week until leaves begin to grow.

STEP 7

Your plants will leaf out faster if you mist the canes as often as possible while they’re getting started. Roses need plenty of moisture both above and below the soil to develop fully.

Rose Care Tips

Sun

At least 6 hours a day. Attempting roses with less sun is an uphill (and generally losing) battle.

Space

Good air circulation is essential to keeping disease at bay. Plant roses at least 3 feet from other plants. Prune out branches that grow toward the inside of the plant.

Food

Roses will perform best (lots of flowers & limited disease) if they are fertilized. Choose a fertilizer that is labeled for use on roses. Whether the food is organic or synthetic, liquid or granular, follow the directions on the package exactly.

Roses are greedy, hungry plants. The more you feed them, the more they’ll reward you with blossom. If you’re planting them in the ground, incorporate plenty of organic matter in to the soil and top them up regularly with rose food, rich garden compost and even mushroom compost or chicken manure.

Water

Water in the morning so leaves can dry (on sunny days) before night-time. Use enough water to soak the roots completely, but do it just once a week for established plants. If temperatures are very hot, water more often.

Black Spot

“With black splotching on the leaves. What to do?”

black-spotThis one is familiar to most experienced rose growers. It is one of several diseases that affect roses, and is usually called black spot (Diplocarpon rosae). As shown above, the leaves develop black blotches and the surrounding tissue turns yellow. The disease can cause significant defoliation and reduces the vigor of the plants, and can eventually kill them.

Cultural treatment is your best defense for this. This means picking infected leaves off the plant, removing fallen, infected matter under the plant, providing adequate air circulation and plenty of direct sunlight, and keeping the leaves dry when watering the plant. Overhead sprinklers are a big ‘no-no’ with roses.

Try spreading the frequency of watering out as far as possible between deep soakings. Also, be careful of companion plants requiring more water than roses like. Some roses are more susceptible to disease than others, with wild and shrub roses showing much better resistance than most floral hybrids (hybrid teas, grandifloras, etc.).

Fungicidal sprays can also be used to help control the spread of this disease, but do not kill it off entirely.

Rust

Another of those leaf diseases that rose growers are familiar with is popping up its head now. Commonly called rust, there are a number of diseases that all look similar and have similar consequences. Rose rust (Phragmidium sp.) is common and pictured below, and many perennials in the mallow family (especially hollyhock, but also Mallow and Lavatera) get the undersides of the leaves affected by their version of this disease (Puccinia malvacearum).

These diseases can cover leaves and drain the plant’s energy, and can cause leaf loss when heavily infected. Fungicides such as Immunox and  sulfur can lessen the damage, and it is a good cultural practice to remove heavily infested leaves and avoid wetting the leaves.

Hoa hồng được cho là loại hoa có sức sống bền bỉ, dẻo dai và mãnh liệt. Một cây hoa hồng có thể chịu được 5 ngày liên tục không tưới nước.

Những lưu ý cơ bản khi chăm sóc hoa hồng

Thứ nhất: Bạn cần cung cấp đủ nước cho những khóm hồng. Nếu trồng hoa hồng trong chậu, bạn nên tưới nước 2 lần/ngày sao cho chậu cây đủ độ ẩm. Còn nếu trồng hoa hồng trực tiếp xuống đất vườn, mỗi lần tưới, bạn cần đảm bảo lượng nước đủ nhiều và đủ ngấm sâu tới tận rễ cây.

Thứ hai: Hoa hồng sẽ không ra hoa nếu thiếu ánh sáng mặt trời, vì vậy, hãy chọn khu đất thường xuyên có nắng chiếu để trồng hoa hồng. Cây hoa hồng là loại cây ưa nắng, cây cần ánh sáng trực tiếp từ 3-6 tiếng mỗi ngày, nếu đủ ánh sáng cây mới sinh trưởng và phát triển tốt.

Thứ ba: Bón phân đúng cách sẽ giúp khóm hồng của bạn sinh trường, phát triển và ra hoa đạt màu sắc đẹp, hoa lâu tàn và hương thơm. Hoa hồng cần trồng trên đất thoát nước tốt, ví dụ đất cát pha, đất mùn, hạn chế trồng trong đất thịt, phù sa vì sau một thời gian trồng cây, đất sẽ bó chặt bộ rễ của cây làm cây chậm phát triển.

Phân bón: Bạn bón phân cho hoa hồng vào đầu mùa xuân vào trước hoặc sau thời điểm ra nụ và cho hoa, vì thời điểm đó cây cần rất nhiều chất dinh dưỡng để cung cấp cho hoa. Phân bón trước khi ra hoa thường là tỷ lệ NPK 10-20-20 (hoặc tỷ lệ tương đương) và phân bón sau khi cây ra hoa thường là tỷ lệ NPK 30-15-10 (hoặc tỷ lệ tương đương).

Tưới nước: Tưới nước hàng ngày vào buổi sáng hoặc chiều mát để giữ ẩm cho cây, cây dầy lá tươi tốt thì tưới nhiều nước và ngược lại để tránh úng rễ. Ngoài nước thông thường, thỉnh thoảng bạn có thể dùng nước vo gạo, nước chè, nước đậu nành để tưới thêm cho cây.

Cuối cùng: Bạn nên cắt tỉa hoa hồng vào lúc sáng sớm hoặc chiều mát vì thời gian này cây có nhiều nhựa, nhiều nước nên hoa sẽ lâu tàn. Trước khi cắt hoa nên tưới nhiều nước hơn bình thường. Sử dụng dao sắc hoặc kéo cắt cây để không làm dập nhánh cây.

Ðể hoa hồng liên tục ra hoa là bạn hãy thường xuyên bấm ngọn các cành đã ra hoa, đồng thời bấm 2 đốt lá tính từ hoa xuống dưới để kích thích cây ra chồi mới. Cây hoa hồng càng lâu năm tuổi, càng nhiều chồi và ngọn cây thì sẽ ra càng nhiều hoa.
