Containerised Roses

 

Most roses have deep root systems and because of this many varieties do not grow well in pots and containers,

However,this situation has been eased in recent years with breeders breeding cultivars to fill this niche in the market.


Here are a few suggestions to help you to select varieties / cultivars that are suited to containers.

  • For containers that are a minimum of 200-400mm (8”-16”) deep, consider using Patio or Miniature roses.

  • For containers that are are 300-600mm (12”-24”) deep or over,consider Compact groundcover or Climbing roses.

  • Half standards need pots of at least a similar depth, but with a base that has a larger surface area to increase the pot stability, particularly if they are situated in areas exposed to high winds.

For the best results grow plants in as large a pot or container as you can, this not only gives greater compost volume, but can also increases the stability of the container.


Type of Container:


Container may be made of wood, metal, concrete, stone, plastic or clay.


Locating the container:


After choosing the container and before filling it, decide on a position for the container as it may be too heavy to move once filled.

Also when positioning the container remember that roses love sunshine and should receive sun for at least half the day.


This can be done by sitting on bricks or purpose made feet.

As an alternative, rest it on a bed of gravel.


Filling / Planting up the container:


Do not use polystyrene as a drainage layer, as this will potentially lighten the weight of the pot making it more susceptible to being blown over.

In recent years good loam is becoming more difficult to get hold of, so as a substitute, use a mixture of home made compost and or farmyard manure mixed with a good quality potting compost.

The finished soil surface should be slightly below the bud union (where the rose is grafted onto the rootstock).

Top up the container with compost if the watering has caused settlement.


Aftercare:


If doing this, ensure that the finished surface is slightly below the bud union (where the rose is grafted onto the rootstock).


Feeding:


To do so will encourage soft growth that may be damaged in winter.
