My garden in the heatwave

I planted my window boxes with trailing petunias, and they have just wilted in the heat.

The rest of my tubs are not so bad, but I have to do a lot more watering than usual.

I don't think our English bedding plants are compatible with heat waves. I shall have to think of plants that are more suited to a hot climate.

I agree, some of the blooms have just dried on the plants!
It’s worth making a note of the ones that survive the best. I’m finding that Sweet William, dianthus (SW family) and Armeria are doing well. Eryingum are about to bloom, but anything with delicate petals is just not coping. My Sweet Peas are quite sparse with short stems.

My salvias usually do well in the summer. This year they're all burnt.

In my troughs, daisies of various sorts are doing ok. If lavender wasn't so spindly I'd plant that in window boxes.

You would assume that bougainvillea would be happy with the heat we’ve had, wouldn’t you 🤷‍♀️ I had to move the pot to a shadier spot.

Busy lizzies are fine, as are a few violas still flowering from winter.

Marigolds, Californian Poppies, Geranium, Roses all doing well as well as my established shrubs. However my grass is struggling, I have a man cut it every fortnight trouble is its scalped and weak after last years weather. I think it should be left this week, there's only a few good patches that are greening up but nervous in case he won’t come back,

Just ask him to lift the blades on his mower so its not scalped. I'm going to lift the blades when i cut mine this week.

I’m not keen on marigolds in pots but geraniums and begonias thrive well in heat. I still water the pots once a day late evening.

The problem is the wet winters as well. Several of my plants didn’t survive as I suspect the roots were drowned. Plants are very expensive now so we really need ones that will survive the wet and the heat.

Dianthus are all doing well, and I have several jasmines that are flowering brilliantly. Honeysuckle is not happy and has produced lots of dried up blooms in spite of lots of watering from me.

I planted a window box with 3 small round lavenders in a row which look rather nice. They were Munstead I thijk which may stay chubby more than spindly. I will plant them up in bigger pots on in the ground in the autumn and then buy 3 more next spring.
I will make a list of suggested plants above and keep to them next year.
I have tubs of geranium, hardy fuschias, heuchera, sedum, lavender, rosemary, roses, hydrangeas.well watered and in the shade... dianthus. And they are all doing fine. Two more hydrangeas are in the ground and in full sun. The sun is bleaching the colour from their petals and burning the leaves. They get a good water each night. Hopefully they will survive.
Fuschia does well in the heat.

Luckygirl is your jasmine the one which scrambles over fences and smells wonderful especially at night?

Gin Thu 02-Jul-26 21:27:38

My jasmine is just. Smothered in blossom. I am sitting by the open French window at almost nine pm and the smell is so strong it is filling the whole house.

My beans are not doing at all well French and runner, flower wise the Shasta daises are giving a magnificent show as is the white escalonia. However petunias and sweet peas are struggling. I water them well but they are just getting burned up. All my effort!

HelterSkelter1 Thu 02-Jul-26 21:59:19

Gin I must plant one to scramble over my fence near the house. Can you tell me the name of your one please. Easy to grow? Do you cut them back?

I agree, my pelargoniums look great and so do begonias and busy lizzies, they all like the sun and the heat.
Strangely my tomatoes aren’t doing all that well.

This is one of mine. I planted clematis underneath to grow through it. You might be able to see that I’ve taken it to grow through a ragged Rosemary.
You do have to prune soon after the blooms have died.

I noticed this afternoon my son's hydrangea in a pot looked very stressed despite being watered. The side of its tub was too hot to touch so the roots inside were literally being poached.

As many of my plants are in containers I've been looking online for ways to insulate them against the heat. There are some suggestions, like using thin cork. However I mainly try to put a pot inside a larger one so there is a gap. Also, wooden half barrels are better than plastic or terracotta. More expensive, of course.

Helterskelter1 mine is a star jasmine ,trachelospermum, I am sure that is not the correct spelling but near enough! It is on the corner of the house and I only prune it when it starts invading the living room. I will try and take a photo later

Gin Fri 03-Jul-26 12:08:33

I am not well versed in adding photos I hope this has worked.

HelterSkelter1 Fri 03-Jul-26 13:46:55

Thank you That looks perfect. I shall aim for similar close to my patio windows

pably15 Fri 03-Jul-26 13:51:35

petunias not doing so well, hydrangea blooming ,but the leaves are turning brown...

Stillness Fri 03-Jul-26 13:52:23

I think we may all need to rethink gardens. I’ve abandoned the annuals I used to have and now have lavender in pots, geraniums and begonias. I dislike the latter but they survive neglect, especially if on holiday.
This year, a hydrangea only has two blooms and I don’t know why, and tomatoes are hopeless in the greenhouse. It’s a wonder we can grow anything in this climate now.

HelterSkelter1 Fri 03-Jul-26 14:40:05

This year my potted hyrdrangeas are full,of flower, but I have put them up the side of the house in the shade for the next heat spell so cant see and enjoy them
