Gardening Tasks to Complete for UK Gardeners in June 

By  Enda

This is our June guide, that suggests which gardening tasks, you should consider doing in the month of June.

Well as you would know, Spring has sprung and summer is now on the way. June is of course usually a sunny month for weather, but one that is often also a rainy month.

As always the weather can vary a lot between the North and the South of the UK.

That said the garden usually comes into its own in the month of June. This is always a time of growth in the garden. 

If the month happens to be a dry one, then you need to keep regularly watering plants during this important growth stage.

Another task that will take up some of your time will be the controlling of weeds, which also grow quickly as the air heats up.

Sadly we are still prone to a lot of light to heavy rainfall and that can make gardening in June sometimes difficult. There is also the chance of strong drying winds, and indeed good amounts of sunshine. With all of these potential combinations, it is indeed a tricky month for gardeners.

What Gardening Tasks Should You Have in Your June Plan?

There are some good general guidelines that I would like to offer for all gardeners in the month of June. I have listed these below, and I do hope that you find them very useful.


Do not depend on the rain for watering your plants. Ideally you should not wait until you see the plants starting to wilt or flag. Do not be afraid at this time to soak the soil rather than just wet it.

Use a light spray when watering and if possible use a watering can rather than a hose, as that better replicates the impact of rain.

The best time to water plants is in the cooler mornings and/or the evenings.


June is a good month to make use of mulches. This really does help cut down moisture loss from the soil. Another big advantage of a good mulch is that it really does help control weeds.

Any type of mulch works well and most are made from various organic materials such as compost, moist peat, weathered sawdust, chopped straw, pulverised tree bark etc.

Spread it around the rooting area of your plants, under branches, stems etc and leave the area around the base of the plants or shrubs bare. It is best to spread your mulch when the soil is moist, ideally after a good rain shower.

The UK Flower Garden in March

Keep a close eye on annuals and as explained above water in the mornings and evenings for the best results. Hardy annuals will start to come into flower in this month of June, and these include anchusa, bartonia, iberis, Californian poppies, gypsophila, night scented stock, morning glory and others such as Virginia Stock.

You should also start to see some half hardy annuals like the marigolds, lobelia, nastrurtium, petunia, come into bloom

Even biennials like the canterbury bells and sweet william will now start to bloom. With all of the above remember to dead head regularly and these should keep flowering from June through to September.

Can You Sill Plant?

You can still plant gladioli, dahlias and begonias.

The Vegetable Garden in June

You can still sow French and runner beans and in the South of the UK, can continue sewing these until early July. You can also sew Savoy cabbage, carrots, lettuce and parsley.

This is also a good month to plant out celery and leeks. You can also plant out winter Brussels Sprouts and Autumn cauliflowers.

You should not cut asparagus much later than the end of June.

The Fruit Garden in June

If you haven't already done so, now is the time to get netting over your strawberries. 

This is also a great month to thin out gooseberry fruits, and they should be about the size of a marble. Gooseberries of this size are great for cooking, and if you allow them to grow out make a great dessert.

Thin out per tree fruits around the middle of this month to a cluster of around 3 fruits.

If you have apple trees you may notice the famous "June drop." When that happens then also thin these out to 2-3 apples per cluster.

June Garden Summary

As you can see there is plenty to be getting on with. This is the time, weather permitting, that I also like to do a general check for any plants being attacked by pests. 

If the weather gets bad, I do head into the shed or garage and do some basic maintenance on the lawnmower and my other gardening tools. I am not talking about spending hours here, but maybe an hour on a Sunday afternoon, you can certainly get a lot done.


I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
