One hot day thought they were above some black plastic and I noticed they'd suffered from the heat a bit so I planted them in the garden and they seemed fine.
But today one has wilted very badly and looks like it is dying - do you reckon it's because of the heat or is something else wrong? The ground is a pretty average loam that I added some compost to and it is watered every night during this warm weather but not saturated. Pour the liquid into a spray bottle, and spray the leaves of your lupins in the evening when the weather is dry.
The slugs and snails will not like the garlic, and so will leave them alone. Do lupins multiply? Lupines reproduce in the wild from seed germination and from rhizomes, or shoots emerging from underground stems.
Wild lupine seeds may germinate the same season they appear, or they can remain dormant for at least three years. How long do lupins last? Lupins will live for at least five years or more and can continue for up to 10 years, dependant on the the conditions they are grown in.
Here's a little advice to help you keep these beautiful plants looking great each year. How do lupins spread? Individual lupines plants do not spread. As they get older the root gets bigger and sends up more flower stalks.
When dry, break the seeds out of the pods, and plant them in a nursery garden in late fall or early spring. How do you feed lupins? A high potash feed of tomato feed or Vitax will give good flower colour if in pots. Do not use farmyard manure, even well rotted, as it will rot the crowns.
Lupins do not need feeding once in the ground as they have nitrogen fixing nodules on their roots which capture all the nitrogen they require from the air. If your lupine is ailing, it's likely that its basic requirements are not being met.
Although lupines tolerate poor, dry and sandy soil, they suffer if the soil is wet. Well-drained, nonalkaline soil is mandatory for this native. A lupine planted in alkaline soil with a high clay content will not thrive. Soil that is too heavy, too wet or has too high a pH causes iron chlorosis, signaled by a yellowing of the lupine leaves, and root rot caused by fungi of the Rhizoctonia and Fusarium genera.
Root rot inhibits seed germination and causes a general decline of the plant. If water is pooling around the stems of your lupine or a testing reveals that the soil pH is over 7. Discolorations of the leaves as well as dying foliage are typical signs of such diseases. Fungicides can be quite handy, but we suggest looking into what your plant has before dealing with it.
Watching your plant on a daily basis can save you from problems later down the road. These plants are extremely sensitive to how much water you give them. Spotting yellow discoloration on the leaves can be a sign that the water content is too high, or that the pH levels are too much. Begin by adjusting your watering schedule. Allow the plant to dry out more before giving it more water.
Are you still curious about this phenomenon? Read our article on yellowing leaves. Typically, a droopy plant is never a happy one. This can indicate that your Lupinus is getting too much water, or that it has become rootbound. Scale back on the amount of water and then consider carefully transferring it to a new container that is larger. If you notice a white, dust-like substance on the leaves prior to them shifting to brown, then it could be a sign of powdery mildew.
For harder cases, invest in fungicide. The foliage of Lupinus is supposed to be standing tall, not curling to the side. Removal of such pests is top priority! This can be done through gently spraying the leaves with soapy water, hosing it down, or through the use of insecticide. Lupinus makes for a great addition to the home. Forget what you should focus on.
Read our little cheat sheet! Most perennial plants are known for coming back over and over. You can expect them to last anywhere from two to five years. You can either grow these plants in the safety of your home, or out in the backyard. Those in the home should be placed in a warm room with quite a bit of sunshine. This includes the blooms.
