They do best in temperate climates, their preferred site is one that isn't too hot and they do well in light, dappled shade, with shelter from cold north and east winds or westerly gales, they prefer moist, acidic soil but do not like to sit in wet/soggy ground in winter, with regular watering in summer so they dont dry out, good drainage is a must. They are slow growers so should be ok in pots with some winter protection. Did you put them in acidic compost and water well all summer?

Hi thanks for the info. To be honest i am not really sure what type of compost i used and i am unsure how often to water then as i am a complete novice at gardening. I guess for your comment that they are not suited to the spanish climate as the summers are really hot and winters quite cold. I will buy some acidic compost and try potting them again but my guesses are that they are going to struggle with the heat.

I think you could try watering more and make sure the compost is moist. But the hot sun will burn the leaves so try to give it dappled shade in the cooler side of the house. Hopefully someone else might know more about your climate and growing Acers?

I will try again tomorrow. Thanks for your help. Fingers crossed.

I live in Spain, although in the north, and brought an Acer with me from Britain almost four years ago. It was about 6 years old then. I kept it in a large tub for two years, then transferred it to the garden and it now looks amazing. We too have very cold winters, occasional strong winds and blistering summer heat, but the Acer seems to like its semi-shaded position - so don't give up hope just yet. ;o)

The semi shade and acidic soil are the two most important issues followed by keeping well watered. Acers will not survive in your house. As Nariz says they can take the cold of winter it is the heat of summer you need to be careful of.

Thanks to all for the comments. I have some acidic soil now am am of to plant them. Wish me luck.

Good luck Lilz

Good luck too
