I had a similar issue when I was redoing my garden. Most local shops don’t carry sizes big enough for larger plants, especially if you need something sturdy for windy conditions. I ended up ordering from extra large planters on Idealist’s website https://idealistplanters.co.uk/extra-large-planter-pots/ and it was a game-changer. Their planters are solid without being too heavy to move, and they have great drainage, which is crucial when dealing with big plants. I’ve got mine on a slightly elevated part of the garden that catches the wind, and they’ve stayed in place perfectly, even during some pretty rough storms. I’d definitely recommend them if you’re looking for something that combines durability and design. Plus, they come in a variety of sizes, so you can easily find what you need. The buying process was super smooth, and the quality is fantastic, so I’d say give them a go!
