I planted Box hedge cubes in 2021. I’ve never grown Box, none of our direct neighbours have Box. Within a year Box Moth caterpillars had decimated them.

Not wanting to embark on a lifetime of managing Pheromone traps to fight them, I dug them out, replacing with Yew.
Last few years it’s been a bigger problem in my experience

Without teaching you to suck eggs :lolol: . Did you take that lawn down to soil level and remove the cuttings away. You have to be brutal.

I find it takes a few cuts for the mower to cope with that.

For the final mow then seeding, I waited until October when forecast rain was a cert.

I’m confident I can tun the @LamieRobertson and @WATFORD zero patches into mini meadows :smile:.

I have bought plugs before to add biodiversity eg Primula vulgaris and Primula veris, otherwise Oxeye Daises can dominate.
I did all of what you said…now stick to your day job….you’re becoming too good at this gardening lark 😂

Climate change. Since 2000 many pest and microbe invaders, as well as the furnace like July’s are literally killing species of trees used to a temperate climate. A recent gardening programme mentioned in passing that all Birch will disappear from SE England in the coming decades due to unprecedented heat/summer drought.

There is no cure unfortunately. There's various chemicals that you could try, but I wouldn't waste the money. They'll never be the same again. If they've had it, dig out and replace with dwarf holly, dwarf Euonymus, Photinia "Little Red Robin", or other short growing evergreen.
Just seen a "Garden Rescue Visited", and all the Box hedging in one garden had to be replaced. I don't know why anyone would use it in the first place, knowing you're on a hiding to nothing.
I’ve a customer who thankfully I just cut her grass …..she’s replaced the box hedge she planted with…..yep u’ve guessed it more box 🤦‍♂️

You sure it wasn’t the T*****? 😉

Both of them I’d say, trimmed it right back today.

This time of year, that ain't no box blight, that's box hedge caterpillars, trust me I have experience

I have taken to using this, together with the pheromone traps show above

It seems more effective than what I've been using before. You will need to spray them immediately and get the pheromone traps out immediately. It's an annual battle for me, but I have a lot of metres of box.

Here's my post from a couple of years ago

I have a couple of these pheromone traps, front and back https://www.greengardener.co.uk/product/box-tree-moth-buxus-trap-lure/ which aren't cheap, but at least the lures last all season and get the moths.

However, in addition, for the caterpillars 2/3 times a year all the boxes get trimmed and sprayed with https://www.ebay.co.uk/itm/22462825...MIo5b_2a3B-AIVEoFQBh1w8wz0EAQYAyABEgLo-fD_BwE I use the concentrate as I have a lot of box hedging at the front and it takes a lot of spray (maybe 4-5 litres per spray). Over the last 3 seasons this has managed to keep them at bay, but despite using the traps all year, I've still had to spray.

There are nematodes that can be used and are far better for the environment, but it's already costing me a fortune just using the two products above. Quite frankly, unless you have a lot of Box, it's probably better just to dig it up and replace it with something else. I think long term that box trees and hedges may be a thing of the past in Britain unless they can somehow breed a species which can survive the caterpillars :shrug:

We had a bad outbreak of that about 2 years back and started spraying it with this stuff. I spray it 3 times a year and so far it’s holding its own and only one small area about size of a saucer that now affected. The rest has a glorious fresh green growth all over.

Thats all well but have to say if it were to get bad again and this not hold it off it will all come out sadly.

Current warm weather has encouraged a lot of growth in grass…hedging etc re my work and in my own garden as most of the roses are starting to bloom

Lovely time of the year, extra special after 7 months of rain.

In this border I planted two Hawthorn Paul’s Scarlet in 2022, lovely just now. With Rosa Ispahan that can take part shade, the buds are just opening.

Hi folks. My younger brother bough me a Rosa Tequila Sunrise ('Dicobey') for my birthday. The question is this.

I am pushed for space in the garden because I am planter and have been her 35 years. My choice is limited to a border space snug to a solid fence on the edge of my patio in a strip of soil only a foot wide, or a pot. I have a big pot that is quite narrow (1 foot square) but a metre deep.

Thoughts?

RHS seems to suggest that a pot may be OK, without saying so.

weeds are good for organised chaos

Some of my garden pics - some wild borders - nothing planted in top pic except purple Salvia in background- just self-seeded over the years. ( I’ll post some more in due course - I let grass grow long around the pond but it’s not fully flowered yet.)

Dig over the soil in your garden where you want the Rose to go, to a depth of about 40cm. Incorporate a good bucket or so of organic material, like compost, or similar bought from a Garden Centre, and water like buggery after it's been planted, and weekly thereafter until September. Watch it romp!
Plants in containers vary rarely out-perform those similar in the garden.
