How to Grow…Roses?

Perfect to plant throughout the entire year, growing roses in your garden creates a colourful and delightful atmosphere. Selecting the ideal roses for your garden depends on what environment you can provide. Some roses can grow as tall as 30 feet (such as climbers) and some as short as 36 inches (such as miniature roses).

There are also rose pests to consider alongside blooming times. Some roses only bloom once a year, and the weather conditions can affect the quality of the flowers. A bloom booster will help your roses to have beautiful and healthy flowers, combined with a minimum of six hours of sunlight.    

 

The Basics of Growing Roses

Tip: If you’re planting bare root roses, soak the roots in water for approximately half an hour so they are properly hydrated before you plant them.

 

Location

When planting roses, make sure that you don’t have any competing plants nearby, as roses will compete for both sunlight and moisture. Leave approximately three feet between roses and other plants, and approximately two feet between other rose plants.

Make sure to avoid planting your roses in windy areas, which can cause the base of the plants to lift from the soil. Should this occur, the plant can grow at an angle and potentially die in extreme cases. Use vertical support for growth if needed to ensure the plants stay in place.

Soil

Well-drained soil rich in nutrients are perfect for roses. Make sure to prepare the soil first by digging it thoroughly so that there are no weeds or stones for roses’ roots to spread out freely. Dig a hole of approximately a foot and a half by two feet.

Break up the soil at the bottom of the hole so the roots can dig deeper and position the roses with their stems towards the wall and with the roots facing away from the wall. Fill in the space around the roots, making sure to cover them properly, and firm the soil on the surface do the roses are secure.

 

Water

One of the most important steps in growing roses, ensuring your plants have the right amount of water will give them happy and healthy lives. You should apply water directly to the soil and water frequently to keep a balanced level of moisture. Avoid watering over leaves and flowers, as the moisture can encourage diseases to develop.

Follow a guide on how many litres to water the different varieties of roses:

  • Potted roses: Five litres of water
  • Shrub roses: Five litres of water
  • Standard roses: 10 litres of water
  • Climbing roses: 10 litres of water
  • Rambling roses: 10 litres of water

When planting and growing roses in the UK, there is no need to water them during the months of October to February. The rainfall levels are enough to provide your roses with the amount of moisture they need.

From March to May, you should water already established roses once a week and newly-planted roses every two to three days. Between June and September, newly-planted roses should be watered every other day and already established roses around once a week.

Feeding

To have beautiful and healthy roses, make sure to feed them to provide all the nutrients they need. The less stressed a rose plant is, the less chance it will succumb to diseases. Repeat-flowering roses, in particular, appreciate being fed. For better results, you can feed your roses twice a year:

  • Feed your roses at the beginning of their growing season, from late-March to April
  • Once the bloom cycle has finished, around late-July, rose feed will promote stronger repeat flowering

 

Pruning

Roses need to be pruned regularly to remove dead leaves and encourage healthy growth. Leaving any dead or weak stems can promote diseases, so by pruning them you increase air circulation and decrease the risk of a fungus issue. You also help to stimulate new growth and encourage new blooming, easily done with a specialised pair of scissors for clean cuts.

 

Rose Pests and Diseases To Watch Out For

Within a wide variety of rose pests and diseases, there are a few more common and more serious to watch out for before it’s too late:

Pink Roses

Powdery Mildew

Also known as Podosphaera pannosa, powdery mildew is a fungus that causes white growth on roses. It affects all the aerial parts, spreading through microscopic spores. Moisture and poor air movement are conducive of this disease, which is why it’s important to not wet the leaves and the flowers of roses.

Some symptoms of this disease are:

  • The typical white growth caused by the fungus
  • Flower buds not opening appropriately
  • Distorted and discoloured leaves
  • Stems and flower stalks become thicker than healthy ones

 

Black Spot

This fungus, Diplocarpon rosae, is the worst disease that can affect your roses. The leaves are seriously infected from spring and onwards and will remain so until the leaves are removed. The plant’s vigour suffers, and the overall health of the roses deteriorates.

Some symptoms of this disease are:

  • Black and scabby lesions and patches on the upper leaves’ surfaces, with the possibility of the fungus strands being visible
  • Yellowing of the leaves’ tissues around the black spots, causing the leaves to fall
  • Severe infections can make roses lose all of their leaves

Rose Dieback

This disease can affect your plants at any time of the month. A light infection by either a fungus, weather conditions, or poor soil conditions can often occur. A severe condition, however, can both be very destructive and spread to other plants.

Additionally, roses affected by dieback can also be affected by canker. The fungus can infect the plant through damage already done and precedingly spread throughout the plant. Some symptoms of this disease are:

  • Small black spots
  • The young shoots are noticeably browning and with dieback (mainly in spring)
  • Main stems, twigs, and branches also affected but throughout the entire year
  • Risk of root decay due to dieback

 

Rose Leaf-rolling Sawfly

Alongside aphids, which are a common pest to affect roses, the rose leaf-rolling sawfly is an insect that is mostly active from late April until July. The female insects insert their eggs into the rose leaflets and secrete chemicals that proceed to induce the leaf to start rolling.

  • From the eggs emerge larvae similar to caterpillars who feed inside the rolled leaflets. Some symptoms of this pest are:
  • Rolled leaves with pale green larvae

The affected leaves eventually roll up into tubes, occurring within 24 hours of the egg being laid.
