Hydrangea in a Pot
I'm digging out a mophead hydrangea which is about 2 feet tall/wide. It was
originally one of those indoor pot plants from B&Q, but it's growing well in the border. However, I don't have the space for it now. I'm wondering if it can be grown permanently in a large patio pot outdoors? Or are they just too big for pots? Thanks. |

Hi Gilly, Hydrangeas will happily grow in a large pot; however, don't put it in a huge pot straight away. It is still relatively small for a hydrangea, so put it in a pot that will just take its rootball plus about 1" of compost around the sides. Once it has filled this pot, transfer it to a bigger size so that you can, once again, put 1" of compost around the sides. Do this until it's in the ultimate size of pot. After this, you can 'top dress' the pot (scrape away old surface compost to 2" if poss., then top up with fresh compost). This should keep it happy for many years. If, after a few years, you feel all the compost is becoming sour, or too poor, you may tip the Hydrangea out of its pot, remove (and loosen) as much old compost as possible, trim away any dead or damaged roots, then repot with fresh compost. Above is the broad outline. You will, obviously, need to remember to feed and water the shrub and to prune it in spring. In winter, use pot feet or bricks to raise the pot off the frosty ground. Also wrap the pot well to protect it from frost ... Hydrangeas are very hardy, but they're not too good in ice cubes! The great advantage of growing Hydrangeas in pots is that you can plant in ericaceous soil for blue flowers, even if your garden soil is alkaline. If you're happy with pink flowers, then any 'Tree and Shrub' compost will do. Hope this helps. Spider |
