Initially, snail damage may not be obvious but it can spread quickly

Snails will take advantage of the cooler evening and nighttime hours to feed on your jade plants, kalanchoe or hedgehog aloe.
Once they become active in the warmth of spring they will be looking for any herbaceous material to tuck into.
Though they are unlightly to introduce disease to the succulent plant, snail damage can become extensive and look really bad leaving fibrous patchy edges and areas.
Signs of snail and slug damage to succulent plants
Snails eat around 10% of their body weight daily, increasing the amount of the opportunity arises, for your succulent, this will show up in the form of scalloped edges on the succulent leaves.

It’s not for the squeamish, but you can impact snail numbers by simply plucking them off your plants in the evenings while they feed.
If you want to find them, be patient and wait until it’s dark, heading out with a flashlight and a buck of soapy water to drop them in.

If the sails are determined to eat your succulents, you can make it hard for them by using physical deterrents that make it very uncomfortable to access the plant. Try these cheap, simple and effective solutions:
- Crushed eggshells are a nightmare to snails, who will be deterred by their jagged edges
- Coffee grounds are also effective for deterring snails when sprinkled liberally around the succulents.
- Copper is also an effective deterrent which sends a sharp electric current into the snail if it comes into contact with it.
- Diatomaceous earth will dehydrate and lacerate the soft bodies of snails, killing them. This powder can be sprinked arround the base of the plant.
Biological options for snail control

- Attract birds to your garden and they will make short work of any lurking snails.
- Nematodes are parasitic woms that can infect and kill snails quickly. They can be purchase online or form garden centers and introduced into the soil around the succulentes.
- Predatory snail species like the decollate snail can be purchased and released near your succulents to hunt and eat any nearby snails.
Chemicals can also protect your succulents
If snails are still breaking through the biological control, you may want to consider using chemicals. Ideally, limit the use of these chemicals to the vicinity of your succulents so they cannot harm other wildlife.
Sluggo is a well-known bait for snails and slugs that contains iron phosphate as its active ingredient. Put this bait down near your succulents and it will kill the gastropod without harming other garden visitors. The unused bait also degrades completely.
Because succulents are so low maintenance, it’s easy to forget that they can become the prey of a variety of pests.
If you are losing the battle against slugs and snails that are partial to your succulents, you may want to repot your favorite in pots and keep them out of harm’s way.
Unfortunately, snails aren’t the only succulent pests, so keep a close eye on your plants for sap-suckers like aphids, thrips, weevils, and mites, especially during the summer months!
