Blueberry leaves not looking green

but does this apply to a plant thats in a pot ? im going to water it today maybe with some tea (might add lemon juice) but again im concerned about over watering . Come july i think there is going to be much less rain water

 

Even more so if in a pot.
What type/variety of blueberry are you trying to grow.
How hard is your water and what type of filter are you using?
It would be a help if you either added your location to your profile, or would indicate where are you in the UK.

 

This is not looking good. Ive attached today's picture. I think maybe I will leave it for a while as it's probably getting too much nutrition

It still looks like sun scorch to me, has it been moved to a sunnier position recently.

The leaves behind the front ones appear to still be green.

 

@hi2u_uk when were they planted?
If you only got them and planted them recently they could have been in a polytunnel before you got them; then assuming that where ever you are residing has had similar amounts of sunshine to most of the rest of the UK then it could be sunscorch. it's also been quite breezy which won't help them.

 

I think it's sun/wind scorch as well. It can be hard to keep them watered enough if in a pot and there is a lack of water. One of mine has done exactly the same thing because it was to dry.

 

Sometimes it's a no win situation. I understood that they should be in full sun so it is. I was told not to water too often as its in a pot so I'm watering weekly . I could quite happily increase the watering frequency

 

They were planted before winter last year

 

It hasn't been

It hasn't been moved recently but I guess it has become sunnier so there is more sunlight reaching it
Is it just a matter of increasing watering then . I can give it acidic natural lemon water twice a week instead of once

 

Im just using the Azaleas Rhododendrons plant food every week but i may reduce this to twice weekly

 

The sun scorch isn't because it's in to much sun but a reaction to not having enough water. If the soil was moist then the sun wouldn't be a problem. I have at least one plant a year that catches me out, as pots don't catch much rain and the wind can be really drying. It doesn't take long for it to happen.
My blueberries are in pots and they really need to be potted on, which doesn't help. I have to water every other day if it gets really warm but in an average year, perhaps twice a week from April to October.

 

How dry are you letting it get between waterings, you need to check every day from now on, I really dont think its an acidity problem.

I think you need to rethink the idea that you water it weekly, you should be watering it before it dries out, which will vary depending on the weather conditions.

 

I can increase the watering frequency no problem though I'm away on holiday until next Friday . I thought it was getting enough water but maybe I was wrong l. I recently put a layer of bark on the soil to avoid this

Is this reversible or us it the beginning of the end
