Five Garden Jobs for June

June is often to be one of our sunniest months here in Hampshire and often with some of the lowest rainfall.  Of course, the longest day falls in June, too; on Tuesday 21st this year (weather depending) we can enjoy around sixteen and a half hours of sunshine before the sunrise and sunset times slowly start to creep in again for another year. All that sunshine means that our gardens really start to get into their stride. June doesn’t tend to be a month for big garden jobs but is more about keeping on top of the little, regular ones, like deadheading and watering.  Here’s our round-up of what to do this month.


As a general rule, removing dead flowers from any plant helps to encourage new flowers to form.  A regular potter around your garden in the cool of the evening with your secateurs can be a lovely way to help keep your garden blooming. (The only flowers this does not apply to are any that you hope will turn into a crop, of course!)

As spring flowering shrubs and perennials start to fade, now is a good time to cut them back and thin out older stems; it may even encourage a new flush of foliage.  This applies to species like Philadelphus, Pulmonaria and Choisya.  Now is also a good time to summer prune a Wisteria, reducing the long side shoots, to help encourage flowering next year.

As you prune, think about whether your prunings might make new plants.  Softwood cuttings taken from houseplants, shrubby herbs, Pelargoniums, Hydrangeas and more can all do well at this time of year.  Get them into moist but well-drained compost as quickly as you can and place in a bright spot, out of direct sunlight.

Plant & sow


If you haven’t already, now is the time you can safely plant out anything you have been bringing on indoors; the temperature here in June rarely falls below 12’C, even at night, so it’s unlikely there will be a frost. Tender exotics like bananas and cannas, to veggies like sweetcorn and courgettes, can now take their place in the garden. Don’t forget to water them in well.

It’s not too late to sow some seeds, either. Now is the time to sow biennials, plants that germinate in the first year and flower in the second. These include such familiar favourites as wallflowers, black-eyed Susans and foxgloves.  You could also sow small pots of herbs for your windowsill now to keep you in fresh leafage for the rest of the year.

Tie in

As plants get growing, they will often need a little extra support until they establish.  For example, sweet pea and clematis will ‘cling and climb’ with their wonderful tendrils but may need tying in when newly planted until they can get a grip.

Tying in the new stems of climbing and rambling roses horizontally will encourage more flowers.  Tying in the new stems of soft, cane fruits (raspberries, blackberries etc) helps prevent potential wind damage and makes the fruit picking easier later on!

Really tall plants, like those cottage-garden favourites delphiniums, hollyhocks and some tall-growing dahlias, would probably benefit from the support of a cane in case they get top-heavy or the wind picks up.  Theory has it, on the other hand, that sunflowers are better left unsupported to encourage their stems to grow more sturdy. Perhaps one to try and make up your own mind?

Feed and water


There is a simple rule of thumb to apply to everything in your garden about when to feed and when to water: if it’s been dry, water but don’t feed; if it’s been wet, it’s safe to feed.  The logic is that the last thing any parched plant needs is fertiliser, it doesn’t have the capacity to process it without water first.

We’d also suggest that – if there has been a particularly prolonged dry spell – prioritise your watering: crops first, pots and containers second, lawns third and flower beds last.  Again, it makes sense that the plants you want to work the hardest (fruit or veg crops) will need water most.  Pots, containers and particularly hanging baskets are more prone to drying out so they come in second.  Lawns can actually survive reasonably well without water: we’ve all seen a brown lawn but has that lawn ever failed to turn green again?  Unless it’s been newly laid, hardly ever; you just have to learn to live with the brown for a while in our changing climate. Finally, unless your flower beds contain plants that you have only just planted, the established ones will have root systems than can find moisture under most circumstances so hold off watering them until it gets really dry.

When watering, use rainwater or recycled household water (grey water) whenever you can. Not only does it save on your water bills, but it’s better for the planet too. (It might also be the excuse you need to switch to more environmentally friendly shampoos and washing-up liquids!). And water early in the morning or later in the evening when you can; the cooler temperatures at those times mean more of the water reaches the plant without evaporating.


In the winter months, we talk about protecting our plants from the weather; this time of year, it’s more about protecting them from pests!  Thinking about what you’re growing to produce a crop: what protection might they need from anything that could get to those crops before you do?  Soft fruit can be a feast for the birds so think about using netting to protect them; just ensure that what you do use is securely tied and taut so that nothing will get trapped in it. Fleece or solid cloches can be great at protecting vegetables from specific predators such as carrot fly or cabbage white caterpillars.  When you can, always go for a natural or biological solution rather than chemicals, especially on anything you are planning to eat yourself.

One job that fills some gardeners with satisfaction and others with dread is the late-night snail and slug hunt! Particularly on damp evenings, scouting around with a torch can help you keep your local population in check; what you do with them once you’ve found them is entirely up to you (and how squeamish you are!).

N. Haggard 20 September 2022

I just wanted to drop you a quick note to say how delighted I am with my new garden.

Jon, my designer, listened to my ideas and delivered on everything I asked for. I wanted something different to any garden I’d had before, no lawn, no landscaping but packed with plants. He designed such a lovely secret garden, around a statement tree. And I have to commend him for his unwavering patience! I changed my mind a hundred times but never did he give me the impression that he was losing patience with my endless indecision. And my confidence in him led me to place an order for over £10k.

My landscaping team, Blade and Tony, were exceptional, from their work ethic, skill and knowledge, to the way they dealt with me, the customer. My standards are very high and I couldn’t fault them.

All in all, a very professional team of people. And it showed that they all care. I’m over the moon with the finished result. I will send you a before and after photo. Thank you so much.

A delighted customer.

G. Gray. May 2022

My front garden has been transformed by Andy and Bradley who both worked incredibly hard and I am delighted with the result. Andy had the vision and skill to turn my idea into reality and I can't thank him enough.

C. Haig Sept 2021

We recently had our garden landscaped by Hambrooks and I just wanted to pass on my thanks, not just for the outcome - which is superb - but for the professionalism of all the staff involved on the job who are all a credit to you company. Mike, Dave, Les and Adam.

H. Sharp Sept 2021

I just wanted to let you know how delighted I am with my new garden. Melanie was a delight to work with and the ideas she had have worked perfectly. Also Sheldon laid the patio beautifully and him and Dave were a pleaseure to have at my house. Quiet workers and polite.

B. Rendell April 2021

I would like to say how delighted we are with the work carried out. Mel, Paul and Tony all worked very hard, they totally took on board the specific need relating to safety as well as the general garden issues. Paul and Tony were excellent at consulting and discussing with me what I felt best in terms of the brief and adjusting if and as necessary, constantly pleasant and polite to deal with. Mel had picked up on particular issues from the first consultation and offered valuable advice. The outcome means a great deal less worry for me going forward.
Altogether a very positive experience and outcome which I would not hesitate to recommend to others.

Stephen March 2021

Dom and Adam's work (garden maintenance) is greatly appreciated. Dom really listened to everything we discussed very carefully and went out of his way to understand and then act upon that discussion. We are extremely pleased with the work done - both to the pond and pyracantha.


We have been coming to Hambrooks for years and it's our favourite garden centre because of its friendly helpful staff and a great selection of plants and trees and the garden design ideas.

“We wanted to write and say how pleased we are with our low maintenance garden makeover. We are very impressed with the attitude of your staff who were prepared to listen to our requirements. Your team John and Rick brushed up and left everything tidy at the end of the day. We now have a garden we can manage and it looks great. THANK YOU HAMBROOKS.”
