Growing roses

Good afternoon @Greg C I am at present still updating this rose Thread but it should answer some of your questions

EVERYTHING APPERTAINING TO ROSES

GROWING ROSES IN CONTAINERS
Only a few roses are tolerant of being grown in containers, as roses generally have long shallow roots for anchoring the plant and searching out moisture and nutrients. As long as deep containers are chosen, a good show of blooms should be achieved.

The best roses for growing in containers are the patio and miniature types, which can be grown in fairly small but deep pots 23-35cm (9-14in) deep. You could also try growing less vigorous, more compact ground cover and climbing roses, but use larger containers with a minimum depth of 30-45cm (12-18in).

The best compost to use is a loam-based John Innes No 3 to which 10 to 20 percent multi-purpose compost or very well-rotted manure may be added for richness. Position the container before filling with compost as it may be too heavy to move once planted up.

Roses love sunshine and should receive sun for at least half the day. However it is important that container-grown plants do not dry out or they will become prone to powdery mildew. If possible position the container so that it is shaded for part of the day, leaving the plant itself in full sun.

Ideally pot up plants in November using bare-root plants, but container-grown plants will do as well, and can be potted up any time between October and April.

Drainage: Keep the pots raised on feet and add a drainage layer of gravel at the bottom to ensure good winter drainage
Feeding: Roses use up food reserves quickly and grow better if top-dressed each spring with a granular rose fertiliser. Additional feeding may be required as per the manufacturer's recommendations. Avoid feeding after August as soft growth may be damaged by cold winters
Mulching: Mulch with a 5cm (2in) top-dressing of well-rotted garden compost or manure to help retain moisture and enrich the compost
Top-dressing: Every second year, remove the top 5cm (2in) of compost and replace with a fresh layer

The Potted/Container Rose

Roses were first sold in pots, as were most plants, to fulfil the demands of the instant gardener but the traditional method of supply is as bare root plants in the winter months, often by mail order. There is little between them as far as the ultimate plant is concerned but there are advantages and disadvantages to both.


As already mentioned, a container rose can be purchased at any time of year (although there are more available in the summer months for various reasons). The advantage of buying a rose in a pot is that you can select the plant yourself during a visit to a nursery oo garden centre. Remember though that the range will be smaller than the range available in grower’s catalogues. A potted rose planted during the summer months will require much more watering than a bare root rose planted in the previous autumn. So tragic to go away on holiday leaving a beautiful new rose only to find it withered or even dead on return.

Bare root roses can be chosen and ordered at any time of the year, though early in the summer is best to ensure that your choice is secured (growers tally orders and the roses available as the orders arrive on a first come first served basis). However they will only ever arrive in their dormant season, usually between the months of October and March. Therefore the first flowers will not be seen until the following year. Obviously they are live plants so need fairly immediate treatment upon arrival. This can be difficult in times of heavy frost or snow. (It is prudent to prepare an area in which to heel in the roses -more on this later). Bare root plants do tend to transplant more easily and have a settling in period before they are required to grow or flower. I would never advise buying a pre-packed rose from a supermarket for you have no idea how long they have been packaged and may well have dried out

Advantages of Bare-root plants:

• You pay less for the same size plants.

• You can carry and plant them easily.

• You only plant them in winter, so they need less maintenance after planting. The ground is naturally wet for their first few months.

• You get the biggest selection: Many Roses are not sold pot-grown.

• They are "asleep" in winter - this is the best time to transplant any Rose
• 
  Advantages of Pot Grown plants
• Pot grown plants can be delivered & planted all year round

POTS

Terracotta is made from clay – which is just a kind of soil – that is turned on a wheel and fired in a kiln. The hotter the firing, the more frost-resistant it will be. This is important because terracotta can crack and flake in very cold weather because the pots absorb water which then expands as it freezes and something has to give.Opt for a pot that provides good drainage. Plastic and clay pots with holes at the bottom offer better drainage ,and I always use John Innes No3 to plant my Rose
Place a one-inch layer of medium-sized bark chips or gravel over the bottom of the container. The chips or stones should be larger than any holes in the bottom of the pot to prevent them from falling through. This layer provides your roses with additional drainage.
Loosely pack the soil into the pot. Do not pack too tightly, as your rose needs room to breathe.
Increase the nutrient level by mixing a cup of bonemeal into the soil. Roses need a lot of nutrients, and bonemeal can provide the fertile conditions your roses need to produce many blooms.Place the rose into the soil. If working with a bare-root rose, spread the roots out comfortably. Rose roots need ample room to spread out horizontally.
Fill in the area around the rose with more soil. Gently press the soil around the stems. The surface of the soil should match the place where the roots and rose plant meet.The container should be filled so that the soil almost comes to the top. If the rose is too deep in the container, pull it out of the soil and add more to the bottom of the pot.Water until well saturated. Even though root rot does pose a threat to roses, these flowers also need plenty of moist soil to survive.Position the container in a location that receives full sun. Roses need at least 6 hours of sun daily to thrive.

 

You are most welcome @Greg C my friend its an excellent choice,I have the Rose "Birthday Girl" in my collection
