Our favourite thing about shopping with Carbeth Plants is their no-quibble money-back guarantee that is available on any plant. We also enjoy their next-day delivery service that is free on large orders over £70.

They also make it easy to save with plenty of Carbeth Plants voucher codes that are often displayed on their homepage. I recently saved 5% when I bought two types of herbs for my allotment and got 20% off a new fuchsia hardy plant for my back garden! By adding a few more necessities to my basket, I was able to receive free delivery on my order, too, making the entire haul a bargain!

Another great thing about Carbeth Plants is their sustainability practices. They offer a plastic-free option on all of the plants they ship to help the environment. They also offer loads of helpful plant care advice to make your green space thrive and your outdoor plants last longer.

Carbeth makes it easy to save on outdoor plants for every season. Shop by plant type, season, space or by your garden type and find exactly what you’re looking for with up to 20% off. Their outdoor range starts at just £5 and includes everything from geraniums and roses to hydrangeas and marigolds in every colour and size. Most of their outdoor plants are included in their sale and can be made even cheaper when paired with a Carbeth Plants discount code. In the past, I’ve purchased a climbing plant that worked well in my cat-friendly garden and managed to save an extra 10% by subscribing to the newsletter.

I also love their range of low-maintenance outdoor plants, including blue grass, cordylines and begonia bedding plants. Carbeth also makes it easy to find exactly what you’re looking for, even if you’re a garden novice, with information on eventual plant heights, the pot size required for each and the season of interest. This makes it easy to find the right plants and saves you time and money.
