Buddleia
Hello People! Hope you are having a fantastic time in your gardens during this Spring!
I have a 2 meters Buddleia tree (shaped as) in the garden of my recently moved-in home. I don't know what type of buddleia is, but absolutely love the idea of attracting as many butterflies and all possible sorts of winged animals as possible. Although, the plant is full of dead brown flowers and I have been reading that deadheading shall be done as soon as flowers start to dry and pruning by early Spring. So, the question is: Shall I deadhead all dead flowers? Or shall I do not or maybe just some of them?
Good to have in mind that I am a beginner in gardening (basic tips would also help a lot) and have just started a veggies and fruits garden (which is actually my priority), so would deadheading now (consequently attracting or not butterflies and/or birds) influence positively or negatively on the growing?
Any help will be highly appreciated! Thx!!

Normally you would cut buddleia right back to knee height in March. As it's now mid May I would reduce half the branches to knee height and cut the rest back to a metre tall.
Give it a sprinkling of rose fertiliser or alternatively a watering with tomato feed and stand well back - it will put on lots of growth and soon be covered with blooms. If you remove each bloom as it turns brown you will encourage more flowers and prolong the blooming period.
In December cut the whole plant back to half it's height to prevent wind rock and consequent root damage.
Next March cut the whole plant back to knee height and feed.
Enjoy the butterflies

Buddleias, I think I'm right in saying, only grow flowers on the new season's growth, so when Dove says to cut them right back, what you're doing here is a) stimulating the new growth, b) making sure the flowers aren't 4 metres off the ground! If you don't cut it back, the plant will still grow new shoots but I think more slowly and certainly on the end of the existing growth, which may be already a metre or so high. I cut mine almost down to the ground (above a pair of leaves / buds) in March, but it's a bit late to do that now, so do as Dove says and enjoy.
It may be worth bearing in mind that Buddleia globosa flowers on last year's wood, so prune back straight after flower and never next Spring or you won't get any flowers,
If your dead flower heads are long an pointy you have the kind that can be cut back hard and will produce flowers this year Prune and feed as Dove has advised.
In my last garden I always cut to two lengths like this and ended up having a longer flowering season as the longer stems produced flowers ahead of the short ones. Dead heading the central flower as soon as it goes over encourages the 2 side shoot flowers to grow bigger and stimulates more lower down.
It wouldn't be unusual for the growth to become 'splayed' though, especially if there's been plenty of moisture and the soil's decent. Even the standard cultivated varieties grow out to a large size as well as growing upwards.
If you can provide a photo, that will help further
