By the time May comes around, spring is in full swing and with it, some superb & much needed warm weather! But don’t expect it to be warm all month, as the saying goes “don’t cast a clout until may is out”. The classic British weather can catch us out with low temperatures, chilly winds and very occasionally a little frost so don’t put those fleeces or cloches away just yet.
With longer and sometimes warmer days now here, this month is the perfect time to get your garden in order and ready for a season of enjoying your stunning outdoor space! Follow our guide and add the right pieces to your garden to create a beautiful area that works for you.
To help you manage your workload or bypass certain tasks which may not be relevant to your outdoor space, we have categorised this month’s jobs into the following four sections:
With Spring here and Summer quickly approaching, the warmer weather will allow you to spend even more time outside, getting your garden in the best condition possible for the rest of the year. As with April, in May there are fewer of the harder and more intensive maintenance tasks, meaning you can put more of your energy into growing!
There is a great variety of tasks to complete this month from furniture care to lawn care to hoeing and so much more. We have been sure to try and remove any form of repetitiveness and hopefully make this work in your garden as enjoyable as possible.
We recommend completing as many of these tasks as you possibly can before moving on to the other sections of our May gardening jobs.

As the weather continues to improve, as do your growing opportunities which means your greenhouse will soon be a busy hub for growing everything you wish from flowers & plants to fruit and vegetables. With temperatures seeming to be consistently warm, you can even start looking at moving plants that were sown inside, into your greenhouse.
Ensure the structure is well ventilated and there is enough shade in the required areas to prevent scorching but don’t keep the doors and vents open during evenings. There is still a chance of some colder evenings and even late frosts which you should be wary of, ensure you watch the forecasts to prevent being caught out.

Open your doors & vents on warmer days but keep them closed during the cold evenings
To reduce scorching and help to lower daytime temperatures, put up some shading

Spring is now in full flow and your garden should be looking much brighter than in previous months and with a little more work your outdoor space will soon begin looking as summery as it can! Planting, bedding and sowing is a constant feature this month with growing work getting serious.
May can feel pretty hectic and it can feel hard keeping on top of the sowing, seedlings, watering and more but that is all part of the fun of gardening! There is even work going in ahead of even warmer months when plants such as Sunflowers and California poppies will begin to bloom.
Browse the jobs below and complete the jobs that are relevant to your wants & needs and also the capabilities of your outdoor space.

May is the heart of spring and the ideal time for you to start planting seeds outside instead of having to start them off inside or in a greenhouse. The ones you did start indoors in previous months may now be moved outside too after a period of acclimatisation (hardening off) to the outside conditions. The warmer weather creates the perfect conditions for your crops to begin flourishing
