SEVENTY-nine per cent of us are downsizing our Christmas trees this year to cut down on cost and needle-dropping, according to an online floristry company.

A survey for Bloom & Wild revealed 65 per cent of people in their 20s and 30s - the so-called "millennials" - will be buying a smaller and less expensive fir or spruce "without sacrificing the Instagram-worthy tradition of buying one completely".

Bloomandwild.com's charming, mini letterbox Christmas tree, from £32, is real and rooted, arrives with a golden star garland, baubles, fairy lights with batteries and a pop-up pot in a letterbox-fitting box. It can be planted in the garden once the festivities are over.

The 80cm high Nordic rope ladder hanging Christmas tree, £20 from notonthehighstreet.com, can be tucked neatly against a wall and draped with twinkling lights and baubles. Minimalist yet rustic, it is ideal for tight spaces and its wooden slats are crafted from the rounded twigs of the Asian bayur tree.

Marks and Spencer's mini Christmas tree trio, £25, makes sense if you only have space to spare on a windowsill. These little frosted trees in embossed tin containers ideally need a cool position with natural light and can be transferred outdoors after a few weeks into a patio container or garden.

Plant terrariums have become a must-have accessory for living spaces in 2018. These glass enclosures can be filled with indoor plants which should keep thriving into the new year, such as the sheet glass and antique bronze-finish terrarium from crocus.co.uk, £69.99.

Grouped arrangements of potted houseplants are a simple way to bring festive greenery into the home, from the classic scarlet poinsettia to white specimens such as orchids and lilies to create a wintry look.

Meanwhile, Wyevale Garden Centres has smaller versions of the traditional Christmas tree from £20. Perfect for eco-friendly gardeners, these diminutive varieties are pot-grown and can be planted in the garden afterwards, making them perfect for eco-friendly gardeners.
