How To Care For Lupins After Flowering

Lupins, also known as lupines, are a popular flower in the spring and summer. There are many varieties of these beautiful plants, which can grow anywhere from 6 inches to 4 feet tall, and come in colors like blue and yellow. In the fall, however, these flowers will begin to fade and die off. The good news is that the process is fairly easy to manage, especially if you get started at the beginning of autumn.

Lupins are a beautiful addition to any garden, but they do require pruning in order to grow optimally. The best time to prune your lupin plant is after it has flowered. This will allow you to keep the plant healthy without interfering with its ability to bloom. Once your lupins have finished flowering, cut the flower stems down to just above the first set of healthy leaves. This will encourage your lupins to grow more foliage and flowers, resulting in a fuller display next year.

You’ve probably wondered “How To Care For Lupins After Flowering” and aren’t sure where to start. Here are some tips:

Deadheading

When cutting back lupins after flowering, it is important to remember that they are delicate plants, and you should only do so if the flowers are still alive. It is best to cut the dead head of the plant when it has 70 percent of its blooms finished. Once the flowers have faded, you can then trim the side stems and main stem. Lupins do not appreciate hard pruning, and they will take several months to recover.

After flowering, deadheading lupins will prevent them from setting seeds. By removing the dead flowers, you will allow the plant to produce new spikes later in the season. You should give lupin plants about an inch of water per week, and you should be able to expect a second show of flowers a couple of weeks later. Also, deadheading lupines will extend their flowering season by at least one week.

The original blue lupine variety is the hardiest. If you’re growing lupins in a pot, it’s best to stake the plant in order to support its heavy branching growth. You can use individual stem stakes or a grow-through grid for easier support. Although lupines require little care, you should make sure that you regularly water them during dry weather, and remove spent flowers.

Lupins thrive in pots of varying sizes. Their preferred medium is loam-based compost or horticultural grit. After they’ve flowered, they should be planted about 15cm (6in) deep in a well-drained area. It’s best to space them 30cm (12in) apart. And be sure to keep them in a cool place away from each other.

Feeding

Once the flowers fade and the plant has been cut back, you do not need to feed the lupin again. However, you can feed it if you want to encourage the plant to flower again. The plant only needs an inch or two of water a week, but it does need some additional nutrients. For example, you can give it a dose of Vitax, a high-potash plant food.

The best way to deter snails and slugs is to spray the leaves with a solution of garlic and water. Spraying the leaves with garlic is an excellent way to keep the pest away, and it is far less harsh than poison. Especially young Lupin plants, the first few years are vulnerable to slugs and snails. You will need to be vigilant during these early years. Alternatively, you can spray garlic with water in the evening before the lupins flower.

For the first year of your lupin plant, you can start by sowing the seeds indoors or outside in pots. If you want to plant them outdoors, you can sow them indoors in early March and let them grow. Lupin seeds are best soaked in a saucer of water to ensure germination. After soaking, the seeds will germinate faster and have a greater chance of flowering.

Once the seeds germinate, thin the plants so they grow evenly. Lupines are easily grown from seeds. Make sure the soil is well moist but not soggy. You should mist the seeds every two to three days. Feeding them after flowering will encourage new blooms in late summer. Lupine seedlings should be pruned once they produce their first flowers. In the fall, clip back the stems and cut them to encourage further growth.

Protecting from slugs

You can protect your Lupins from slugs by putting up copper tape on the rims of your plant pots. Copper tape is a natural slug deterrent because it reacts with slug mucus to produce a small electric shock. You can purchase copper tape in DIY stores and apply it around the rims of your plant pots. You should remember to clean the tape regularly with vinegar to avoid attracting slugs.

Another option is copper mesh, which is 5″ high. It should be supported by small stakes and curved away from the plant. Egg shells are another option that works similarly to copper. Egg shells are soft and uncomfortable for slugs to slide over, but aren’t as effective as copper. Slugs may still fall over egg shells, but you can avoid their impact.

One way to protect your lupins from slugs is by using a bacterium-based spray. Garlic spray is highly effective in repelling slugs. It should be applied to lupin leaves at dusk or night. A few applications should be enough to protect your lupins from slugs. If you use any other method, make sure to read the directions carefully.

You can also use eggshells as a barrier in your borders. These have sharp edges and discourage slugs from sliding over them. You can also use gravel or sand to create an inhospitable area around the plant. Lastly, some plants may repel slugs. Try planting some plants that repel slugs. Some plants have natural repellent properties and are good alternatives to slug-resistant lupins.

Preservative sprays

Using preservative sprays for Lupins after blooming is a simple way to prolong the life of your flowering lupines. Depending on your specific needs, you can use these on individual plants or on entire patches. These sprays have several benefits. They prevent mildew and bacterial growth and they improve the plant’s appearance. To use these sprays, you should collect the blooms from your plant after they have finished flowering.

Before applying a preservative spray, make sure your lupine seedlings have adequate moisture and are not overly wet. Mist them every two to three days to keep the soil evenly moist. Apply fertilizer every four to six weeks, and again when the plant reaches eight weeks of age. When planting lupines, soak the seeds for 24 hours before planting. Sow one seed in each hole. If you plan to cut back the flower stems, do so carefully, as this will encourage new growth. When the fall foliage begins to drop, prune the plants back to encourage further growth.

Lupin plants are susceptible to snail and slug damage. Copper tape can also help to protect them from aphids, which can grow in large colonies. These pests can slowly weaken your lupin plants. Spraying them with a preservative spray may also be harmful to bees, which are essential for the healthy growth of your plants. You can also use copper tape to protect them.

While fungicides are not a reliable treatment for lupines after flowering, they can prevent a variety of diseases. Some fungicides can reduce the severity of infection, while others can eradicate it altogether. Nevertheless, you must follow a plant care guide for lupins. You should only use fungicides if you have a specific fungus that attacks lupins.

Pruning

To encourage blooms, prune lupins after flowering. When the plant’s foliage turns brown and the flower stalks are dry, remove them and allow new growth to grow. This will encourage a second flush of smaller flowers. Pruning lupins after flowering will encourage the plant to send up new growth in spring. However, don’t cut off the entire plant – leave only the stems that bear flowers.

While pruning lupins after flowering, make sure you don’t use a lopsided pruner. This can damage the plant’s stems and make them rot. Also, lupins don’t respond well to normal slug pellets, so make sure you don’t use them on them. If your lupins have been in the same location for several years, consider replanting them in a different location if they are already established.

Aside from flowering, Lupins require regular pruning to prevent aphid infestation. Aphids live on lupine foliage, resulting in distorted stems and a reduced yield. Aphids also transmit viruses, so be sure to check your plants for signs of infestation. If you find aphids, cut off infested leaves and spray with neem oil. This repellent does not harm beneficial insects – it just kills pesky aphids.

If you want to encourage the plant to reproduce by seed, prune lupins after flowering. Lupine seedlings are best planted in pots and should be planted no more than 18 inches apart. When seedlings are mature, lupines are highly attractive and make great cut flower arrangements. You can start pruning lupine seeds the second year if you’d like. However, remember to fertilize them every month.
