How do I know if I can grow rhododendrons?
Hello all.
I'd love to be able to plant some rhododendrons, but I'm puzzled as to whether I have 'lime free' soil. Is this the same as acid? My soil is quite heavy clay, I try to work in compost and sand when I dig, so it's not too waterlogged, and I was once told by my local garden centre that our soil locally is 'slightly acid'. Can anyone help me out with the terminology of lime and acid? Will I need to buy ericaceous (sp?) compost to plant them? Or am I wasting my time and should I just get over it and plant something else? Thanks for all input, I'm a bit stuck here. Hopefully, Angel. |

Best advice is to look in gardens close to yours - can you spot healthy rhodos or other acid loving plants? pk |

Is this the same as acid? an acid soil will be low in lime - adding lime makes the soil more alkaline and thus less acidic My soil is quite heavy clay, I try to work in compost and sand when I dig, so it's not too waterlogged, and I was once told by my local garden centre that our soil locally is 'slightly acid'. Can anyone help me out with the terminology of lime and acid? you could buy a soil testing kit to discover the ph of the soil in your garden Will I need to buy ericaceous (sp?) compost to plant them? If you really needed to you could, but you would be wasting your money unless you were planning to create a raised bed. The ph of the surrounding soil would otherwise just re-establish itself in your planting area over time. Or am I wasting my time and should I just get over it and plant something else? Thanks for all input, I'm a bit stuck here. I would give it a go - if the leaves start to turn yellow then treat it with some sequestered iron (Miracid). -- dave @ stejonda Alternative Global News : http://commondreams.org// |

rhodos or other acid loving plants? pk No, my neighbour has the usual conifers, bulbs and pyracanthas, nothing interesting at all really. I just have a hankering for some flowering shrubs. I have a beautiful ceanothus in my front garden, but the blue flowers are so small. I think I'll take your advice and buy a soil testing kit and take the opportunity to defrost the freezer while I'm about it. I'll let you know what happens. Thanks. |

If you see pH mentioned in this context it's a standard measure of acidity/alkalinity- Logarithmic scale 7 is neutral, lower is acid, higher is alkaline (limey). Since it is logarithmic 5 is 10 x more acid than 6........ etc A clay will be better for Rhodos etc if you work in plenty of organic stuff - well composted chippings, garden compost, well rotted manure etcto improve soil structure. Ericaceous compost is gilding the lily a bit but if you can afford it mixing some in around the plants as you put them in will probably be helpful. Decent drainage and soil texture is probably more important than pH so long as you're below about 6.5. Rod |

We are over limestone here so we don't normally try to grow rhododendrons - or we didn't until a totally gardening sceptical neighbour gave us a sad looking specimen saying, " Here'y'are, this bloody thing doesn't like me, let's see what you geniuses can do with it" We bought a 40 litre bag of ericaceous compost, dug a big hole and set the plant in. It perked up immediately and flowered like mad the following year - last year. By now the roots must be getting near to our lime rich soil, so it will be interesting to see what it does this year. (Yes, I know they are considered to be weeds in some places, but not in this area.) -- Alan & Joan Gould - North Lincs. |

(Yes, I know they are considered to be weeds in some places, but not in this area.) Our soil isn't suitable either but I am a great fan of them. We dug down about 2 ft along the edge of a ditch . We then lined the trench with polythene and filled it with peat moss. (Please don't start on at me about peat moss, its used around here to make electricity so the little I used is utterly insignificant) The variety of different species we planted are all still doing well 10 years later.
