As the days start getting longer and warmer, it’s clear (and relieving!) to see that summer’s on its way. That’s why May is the perfect time to start spending extra time outdoors, whether it’s sowing seeds and planting out the bedding plants, having a good tidy up or setting up the trampoline for the kids. And if you’re after garden inspiration, don’t miss Chelsea Flower Show at the end of the month too!

So, here’s what you should be focusing on in your garden throughout the month of May:

Get sowing

Now that the weather is picking up it seems like the perfect time to get growing. May is a fabulous opportunity to start getting the garden ready for summer. Hardy annuals can now be sowed direct, including marigolds, cornflowers, larkspur and poppies. And come summertime, you’ll be greeted with a riot of colour in your beds and borders.

Perennials can also be sown in May but this should be done indoors in seed trays to start with. Pansies, geraniums, chrysanthemums and echinacea are all perfect and, once sown, should be placed in a light, cool spot (your windowsill is ideal).

Bank Holidays ahoy!

With two bank holidays in May, it’s the perfect time to get outdoors and spruce up your garden ready to enjoy the glorious sunshine (hopefully!). Clear your patios of algae and general dirt that’s gathered over winter with a good quality patio cleaner. Give the garden shed a good clear out and clean garden tools to keep them working at their best for longer.

You can try organising your shed by placing the lesser-used items to the back – and don’t forget to check padlocks for rust and damage while you’re at it.

Now’s also a great time to give the shed itself a little TLC. Check for damage to the roof caused by the winter months and make any repairs with roofing felt. Finish with a lick of wood paint to prolong its life. And whilst you’ve got the fence paint out, your fence panels might be ready for a fresh coating, too!

Once all the hard work’s done, you’ll want something to relax on. This means the furniture cover can finally come off your long-forgotten patio set and you’ll be able to wash down metal garden furniture sets. Whatever your patio set is made of, why not take a look at our handy care guide here? This will have it looking its best in no time.
