Herbaceous Aftercare Advice
Herbaceous plants are non-woody perennials and biennials that live on for two years. Herbaceous plants die back in autumn but only to their roots. Herbaceous plants are hardy and will stay alive through winter, and will start growing in spring again. Plant bare-root herbaceous plants in the spring or in autumn, when the ground is moist. Container-grown plants can be planted at any time, as long as the ground isn't frozen.
Sun exposure: Full Sun to Semi-shade
Carefully choose the site for your herbaceous plants. This is determinative for the health of your plants. Herbaceous plants love a bed or border in full sun. Plant bare-root herbaceous plants in the spring or in autumn, when the ground is moist.
Herbaceous plants grow well in almost any type of soil. Enrich your soil with organic matter by adding nutrients. This will provide good fertility and improves the texture. Add a layer of mulch to conserve water, reduce the need to weed and keep soil temperature cool.
Water needs: Medium
Herbaceous plants prefer less frequent but deep watering to encourage the roots. Please beware that herbaceous plants only tolerate drought after they have become established.
How to take care of your Herbaceous
Herbaceous plants have endless variations in species. When you've chosen your favourite herbaceous plant, it's best to plant them on a cloudy, rainy day in spring or autumn. Avoid planting herbaceous plants on a hot summer day, or make sure you completely wet the root ball before planting.
The best location for herbaceous plants is a bed or border in a sunny position. Make sure the site is protected from strong winds. Herbaceous plants grow on new wood, so you must choose a location that doesn't catch too much wind.
The essential preparation for planting herbaceous plants is to remove all perennial weeds and their roots. Dig several times through the area to be sure that everything is removed. Also, remove stones and other unwanted material from the soil. Enrich the soil by adding organic matter—herbaceous plants like humus-rich, well-drained soil. Mix a good quantity of well-rotted garden compost or other organic matter into the ground to improve drainage.
You don't need a decent-sized border to fit a good range of herbaceous plants in. Herbaceous plants don't take too much space. Arrange your plants on the surface of the bed or border to help you consider spacing, format, colour and structure. We recommend using tall herbaceous plants at the back of the border and using smaller plants at the front of the border. Please check the label for the exact width and height. If plants are planted out too close to each other, they won't perform well if young plants receive competition from other plants for light, water and nutrients. On the other hand, if plants are too far apart, more mulch is needed to control weeds and keep the soil moist.
Watering is key to perform well. We recommend watering herbaceous plants in the morning, as this is when the sun comes up and plants will start to use water. If watering in the morning is no option for you, water in the evening. Watering in the heat of the day is no good idea because much water will be lost through evaporation from the surface. Right after planting, herbaceous plants need regular watering. Herbaceous plants can only stand a little drought when they're fully established.
All plants require primary nitrogen, phosphorus and potassium and secondary calcium, magnesium and sulfur. These nutrients are often depleted in the substrate and need to be frequently replenished. Select a fertilizer with the correct number of nutrients that's good for your soil. Add a slow-release fertilizer in spring and during the growing season. Topdressing a bed or border with compost provides season-long fertility for most herbaceous plants.
Herbaceous plants need to be cut back right after flowering in autumn. You can cut back old foliage back to the ground. The plant base (crown) will remain dormant over winter and produce fresh shoots the following spring. If you prefer to leave some herbaceous plants with attractive seedheads to add some interest during winter, you can cut them back in spring.
Pests and Diseases herbacous
Sometimes, it happens that pests and diseases cause harm to your beloves herbaceous plants. To minimize the risk of pests and diseases, plant on the well-cultivated ground and choose plants appropriate to the conditions. If you then ensure an adequate supply of nutrients and water and keep weeds under control, plants have the best possible chance of making sturdy, healthy growth.
Aphids are the most troublesome pests. They're also known as greenflies and blackflies, and they attack a wide range of plants in the summer months. To keep aphids under control, apply an insecticide such as 'Rapid'or 'Sybol' every ten days during the growing season.
Caterpillars cause damage to leaves and flowers. You can either remove them by hand or apply pest control using a general insecticide such as 'Sybol' applied as a spray or in dust form. You can also attract natural caterpillar predators, such as nematodes, birds and wasps.
