What Diseases Attack Liriope Plants?
This unpleasant sounding disease is a fungal infection, that can seriously damage the beauty and general health of your Liriope.
You should keep an eye out for the telltale reddish brown spots appearing on the leaves around late autumn, or after a period of prolonged rainfall.
This informative video will tell you everything you need to know about this problem, and what to do about it:
This little beast can cause small bumps on the underside of the leaves, which is not only unsightly but can attract other pests too.
Scale insects survive by sucking the sap from various different plants, and they excrete a sugary substance called Honeydew – it is this that can attract other pests.
If your plants are overrun by these little insects in can cause poor growth and even, in extreme cases, the death of the plant.
Slugs and Snails
These guys really are the bane of any gardener! There is a lot that you can do to get rid of them, and you really should consider the non-harmful ways of doing this.
Slug pellets can be harmful to the environment, so look for alternatives where you can – beer traps, crushed egg shells and fleece around your plants are all great options.
Although liriope is a very hardy plant, it won’t like certain weather conditions and it can go dormant, or even die, if it is damaged too much.
Excessive rain is the worst thing for liriope, as they don’t like having their roots soggy. If the weather is monsoon like, you may wish to consider rigging up a sort of umbrella for your liriope! The neighbours may laugh, but your plants will survive.
Although it is hardy to the cold, long periods of very cold weather will affect it adversely.
If you are the depths of a really cold winter, you should consider placing fleece or mulch around your plants to keep the roots warm and ensure that the whole plant survives.
Leaf and Crown Rot
This is a common ailment for this plant, as well as many others. It is a tricky one, because it’s hard to tell that it’s taken hold until it’s almost too late!
It is caused by Phytopthera Palmivora, a pathogen that finds it easier to take hold in places where the plants are crowded close together.
Late spring and early summer is the time to look out for this disease – check for leaves turning yellow and the base starting to rot.
If your liriope starts to show signs of this disease, you need to remove all of the affected parts, and even move the plant completely.
You should avoid planting liriope in the same place where P.P has taken hold for many years, as the pathogen can linger in the ground for a long time.
This is a problem for liriope, which really don’t like to sit in a bog. Most plants will object to being waterlogged for long periods, and this one is no exception!
Make sure you plant your liriope in some well draining soil, to ensure that its roots don’t sit in moisture and start to rot.
If you notice that the soil around your liriope is looking too damp,and the plant isn’t performing well, you may need to consider moving it, or adding some sand to its bed.
