Any idea what's causing this?

Planted these in spring, yellowing tips on the leaves and the conifer one seems to be going yellow? Any idea why?

 

Hi Gaz, it looks like dryness or scorch, especially on the Box. How often do you give them a good drench ( perhaps a couple of watering cans each twice a week ). Are they in a hot sunny or windy position?

 

Wouldn't say windy. But can get a bit hot. I'll try give them more water see if that's helps.

 

I kind of get the feeling they are supposed to look like that.

 

I ain't much of a gardener tbh. But I do know leaf tips turning yellow usually means there is something up.

 

The box looks to me like a variegated variety, the yellowing is far too regular to be just a disease pest or physiological problem.
As to conifers, some varieties change colour at different times of the year, yellow is not uncommon, often some go a bronze colour in winter.

To me all you pics look pretty good.

 

Ahh ok. I've got a few box ones in the front garden. None of them got the yellow tips.

ahh right. I was just going off the ones I have in the front garden. And these being all green when I planted it. But if some do this that's probably it then. Thanks.

 

You stole my words pete
They all look ok to me.
However GardenGaz, when you planted them what compost did you use? I sense you may have used mpc....ordinary compost from the garden centre? If so this is not suitable and plants will dry out very quickly and nutrients drained fast.

 

Thanks all.

 

I can't remember. Probably was standard compost. If I remember correctly the root balls just fit in the tubs. So not much compost needed adding.

 

John innes (soil based compost) is needed GardenGaz.
"Rootballs just fit in the tubs"....a few alarm bells now!
Rootballs need to be soaked thoroughly before planting. Some of the roots need teasing out too. Pots need to be big enough for those plants to make growth in. If you simply squeezed plants in they will run short of water and prob be worse than they were when you bought them.
Bigger pots and john innes, number 3 Gaz.

 

Sorry when I put just fit what I mean is there wasn't much compost needed adding. I just checked the old pots and they are a lot smaller than where they are planted now. But I didn't soak the root balls. Would you remove them and change the compost at this stage? They've been in there since spring.

 

Yes I would GardenGaz....prob wait until mid September now but soak rootballs, tease out roots if they look congested or tight, use john innes compost and water well. Your plants will thank you for it
