yellow and brown blueberry leaves (forum)

james starts with ...
i recently bought 5 blueberry plants - 3xmisty and 2xlegacy. One of the plants has started developing yellow leaves at the top with some brown edges and curling lower down. The other 4 are perfect and planted in identical pots with azalea potting mix. I live on the gold coast and up until yesterday they received full day sun and lots of sunset sun.

Any solutions?

They resent direct ,hot sun ; nor do they like saline water. The pH needs to be 4.5 to 5.5 or there is trouble with iron deficiency and other nutrients. All in all blueberries are prima donnas.

Could be that different varieties can take varying amounts of sun, as only one of them is having problems.

I'd take it back to the shop james :) Most places will refund or replace given that the other 4 are perfect - take a pic of them in too...

Only morning sun for blueberries is best - especially in warmer climates. I have 6 plants on the go and they are fantastic...I use sphagnum moss for mulch - as it is acidic and helps to maintain acidity. Mine get shade from a peppermint tree from about 11am - noon onwards, in summer.

They like lots of water too. The Low chill varieties are not quite as fussy about the soil as high chill ones - but check the pH also.

I keep mine in the same bed as my jaboticabas as I find they like the same conditions: lots of water, acidity and lots of organic matter...and no hot afternoon sun...

I have about 10 blueberry's growing that are 18 months old bought in 6" pots. They are sooks and like lots of water - in Brisbane with our dry spring we just had it's been a challenge to establish them properly. They are a mix of Sharpeblue and Misty.

I have mulched them with pine needles and added sulphur over time but keeping them moist I think is the key.

A few hot days in a row with wind can set them back dramatically and they are not a plant that recover well after a set back.

They were much happier sitting under the next doors neighbours gum tree until they cut it down - hence more water is required. I will also take on Amanda's sphagnum mulch tip.

I just bought some iron cheletes and further sulphur too add to the bed as I'm not convinced the soil is acid enough.

I'm hoping once that they start establishing themselves root-wise they will look after themselves without much fuss.

I also have been using a mix of diluted worm wee and seasol every 3 weeks or so. Hope this helps.

Here are some interesting comments about sphagnum moss and pH...Maybe as they are both bog plants it's no surprise they get along well..!? ;-)

Some great growers in Perth have quite a collection of b/berries in the ground - they put shadecloth, over trellis above their plants, in summer - from the pics I have seen their garden is quite established also - with mature trees which which cast shade at different times of the day.

Mine grew happily in the shade house in Geraldton..and fruited too...
