First, they only flower in late Spring (here, anyway, probably in your spring too). Second,when you say you fertilise regularly, what exactly does that mean, and what is the NPK of whatever it is you are using? This information should be on the box or packet somewhere, and will be a set of 3 figures with a dash inbetween each.

I do have a red rhodo flowering at the moment Bamboo, but I think it's confused. Sorry, I don't know the variety - it's a car boot sale rescue!

Mine usually flower in May but they are in bud again already which I think is strange. Must be climate change.

The buds will sit like that over winter Casso.

I suspect you are using a fertiliser that encourages leaf growth. We do not feed any of our rhodos. with anything and they flower away happily every year. Occasionally one takes a year off and only puts out a few blooms but generally they flower well. But we have just about ideal conditions for them!

Bamboo - I use stern's miracid(30.10.10) and start fertilizing April 15 - I got these directions from Woodland Nursery in Mississauga. the last two years I have got hardly any blooms - just leaves. Should they not be getting the buds for next years blooms now.

The fertiliser you are feeding them encourages a huge amount of leaf growth not flowers, being high in nitrogen. Stop using and instead mulch with good acidic organic humus/compost. Is your soil acidic or alkaline Gardenergirl?

Agree with Moongrower - that's why I asked for the NPK, and that measurement for the one you're using shows a high ratio of nitrogen to the other nutrients, so stop using that - it will make your plant produce leaves at the expense of flowers. Next year, try a balanced feed if you want to feed it - something with more or less even numbers for all three constituents of the NPK, so 6-6-6 for instance.

Personally we do not feed our rhododendrons or any other plants we feed the soil before planting he mulch as needed.
