Care & Guidance

Whilst you enjoy your perennials for their fantastic foliage or beautiful blooms, it's really the roots you're buying - because the roots allow the plants to come back every year. Use these tips to make sure your perennials get off to the right start.

Container grown perennials are easy to plant and commonly available. Start digging a hole that's a little wider but no deeper than the pot your new perennial came in. Loosen the roots, and spread them out if the plant has become rootbound* (*when roots start to grow in circles around the edge of the pot). Then firm the soil in around the roots and water well.

Planting Tips: water your perennials well after you plant them. Then lay a 2-3 inch deep layer of mulch over the soil around your new plants. The mulch will help the soil hold moisture and prevent weeds from growing. Give taller perennials such as delphiniums, holihocks and peonies support by staking them. Anchor single stems by inserting a rod or sturdy stick into the ground and tying the stem to it. Keep clump forming plants with multiple stems standing, by growing through a hoop. Regularly deadhead and divide your perennials to keep them healthy and looking beautiful.

Deadheading: simply means cutting the faded flowers off your plants. It makes your plants look better and it prevents them from setting seed so you don't have a mass of seedlings popping up in your garden.

Dividing: One of the best things about perennials is that they grow bigger and better each year. But many start to crowd themselves out if they get too big. Keep them performing well by digging them out of the ground and splitting them into smaller chunks every 3 or 4 years. Early spring and autumn are the best times to divide most perennials. A couple of exceptions include bearded iris and hosta: split these perennials in summer.

Watering: There's no one-size fits all rule for watering perennials. Some varieties stand up to drought and others need to be kept moist all the time. Keep your plants healthier and make watering a breeze by grouping plants in acccordance with their watering needs. No matter what perennials you're growing, be sure to keep them all well watered in the first year - that allows them to become well established.

Feeding: If you have rich soil or improve it with garden compost or other forms of organic matter on a regular basis, you probably won't need to feed your plants, But if you're burdened with poor soil, fertilising can be helpful. Take care not to over fertilise - this may make your plants flower less, suffer root injury, or even kill your perennials.

Winter Care: Perennials that are reliably cold hardy in your region shouldn't need any special winter care. But spreading a layer of mulch over them after the soil freezes can help prevent winter damage during an especially cold season. Many gardeners like to leave the dead stems of their perennials standing all winter, providing food for birds. Perennials can help to catch snow, which is one of the best winter mulches.
