Handy hints for growing Succulents in Western Australia


It started with a couple of plants, then I saw a friend’s collection and thought I love these, I want more… and then the obsession began, because there are so many and they are so fascinating and beautiful.

But, then came the questions…how do I look after them?

Here are some handy hints that I have found in the last year of collecting that hopefully you will find the answers to your questions and more.

WATERING

I find that it is best to give them a good drenching, thoroughly water the whole pot. Try not to get water in the crests of the plants where it can puddle and cause rot. Let them then dry out completely before watering again. In winter this is around once every 2 weeks, depending on the rain. In the summer around twice a week.


SUN

Morning sun is the best, avoiding midday sun and early afternoon sun. Always sun harden gradually. Even late afternoon sun can be harsh. Burnt plants will show brown dry patches. Some plants can take more sun than others. When they close up and/or wrinkle up they are probably feeling the heat. Some plants can be grown in low light indoors like Sansevieria (Mother in law’s tongues) but most need good light to grow, I have some in a shaded area that are alive but aren’t growing as there is not enough light. A few plants that will tolerate low light are: Sansevieria, Haworthia, Gasteria, Gasteraloe, Aloe hybrids, some Craassula, some Kalanchoe, some Euphorbia. Some plants will just love the full sun like Crassula Campfire and Senecio Talinoides Mandraliscae (Blue Chalksicks)




POTTING MIX AND SOIL

Many of these plants love being planted in the ground and will reward you with beautiful growth. They still prefer morning or later afternoon sun only or a dappled/shaded area. Adding some soil improver helps, but many are tough enough to survive in the West Australian sand.
Potting Mix – everyone will tell you they have their own formula. It is a matter of trying out various options and deciding on what suits you and your budget. If you are starting out then a pre-made Succulent and Cacti mix is the best way to start, there are various brands including Debco and Osmocote. These mixes provide a more free draining mix than standard potting mix, you do not want the potting mix to stay damp or your plants will rot and die.
Making your own mix can involve many ingredients, most starting with a base premium potting mix and adding COARSE sand (fine will clog up and go solid), and perlite in a rough 3:2:1 ratio.
I have my own mix which involves using Square Foot Soil Mix (from Greenlife, Midvale WA 6056 http://www.greenlifesoil.com.au/soils-and-conditioners/square-foot-garden-mix-25l-pack-of-5 ), sand, perlite, gravel, charcoal, blood and bone, and slow release fertiliser.



FERTILISER

Feed with ¼ strength fertiliser during growing period only – some succulents are winter growers and some summer. They do not need high nitrogen as this makes them leggy and weak. So pick a lower nitrogen fertiliser, there is no succulent specific fertiliser in Australia, but an equal ratio of N:P:K would be ideal.


POTS

It appears that Terracotta pots are the succulent growers favourite as they dry out quickly.
You can pot in what ever you like as long as there is good drainage. In fact it also becomes an obsession finding what unusual items you can plant in.
Many household items can be used and the ceramic drill bit gets a lot of use in my home, and a good investment.






An important fact to note is that succulents grow better with not too much room around their roots. In other words they love shallow small pots, and they love multi planting, they will grow a lot faster this way.

Also I find it good to add some small pebbles as mulch, the roots are near the top of the pot and I find this helps with the Summer sun.


PESTS & DISEASES

You must inspect your plants regularly for unusual signs, rot and mealy bug are the most common killers of succulents in WA, but also scale, red spider mite and fungus gnats.
Keeping your plants healthy will help combat these problems. Also you must keep the ant population down as they spread mealy bug throughout your plants quickly. There are various methods once you have a problem and it depends if you want to use chemicals or not.

CHANGE IN SEASON

Bear in mind that the sun changes position so you may find that your plants are now getting too much or not enough sun. Their watering requirements will change also.
There is a good table here showing the dormancy/growing season of succulents, please bear in mind it is for America so the Seasons are opposite.

WHERE TO BUY AND HOW MUCH TO PAY

In WA we are limited on our selection of plants as import from the Eastern States and Internationally is severely limited and also expensive.
Places I have bought from are Bunnings and Masters (their stock depends on when their delivery comes in and the good stuff tends to disappear very quickly as word gets around). Other local nurseries including Bloomings, Waldecks, Mitre10, Zanthorrhea, Verdure, Fickle Prickles, All Palms Garden Centre, South Fremantle Garden Centre and many more (let your fingers do the walking

http://perthnurseries.com/ ). Also Gumtree, Sunday Markets, and other Fairs and Fetes, plus the various groups on Facebook and the Cactus and Succulent Society of WA have several sales throughout the year.

Expect to pay from $2 for common plants up to $20 and more for a large established plant, rarer ones are dearer, but just because they are labelled rare doesn't mean they are.

Some Facebook sellers that I can recommend are:
OR message me, I often have a few spare bits and pieces for sale, see end of this post for current plants available.

IDENTIFICATION and ID’s

Succulents can be extremely hard to identify because they look different under different conditions, there are many hybrids, and matching a plant to a photo online can be very deceiving in colour, size, thickness and texture.
Succulents vary depending on their age, the amount of sunlight, water, the season, the type of potting mix. Even the experts still argue about classifications and change the names quite often.
The shape and colour of the flowers and the stalk can be very important in identification, and without flowers identification may be impossible.
A lot of plants may be hybrids and just don't have names, even seeds can very hugely, also now plants are being produced by tissue culture and can vary as well.
Also over the years plants have been sold under various different names for the same plants so you may think you are buying one that you don’t have in your collection only to get home and find out that you already have it under a different name.
It is a frustrating business trying to find identifications for plants and can cause a lot of heartache, but it is something that I regard as a challenge and I like to try and ID plants as I learn so much about other plants while doing it.
I have started some pinterest boards to help identify various plants in WA, while generally you can never be 100% sure it is nice to have an idea.


CRESTS / CRISTATA

Cresting is quite common with succulents, it is where the plant suddenly grows in a fan type structure, explained in more detail here

Some examples here

(crested Aeonium Sunburst)

PROPAGATION

Once you have started growing succulents you need to learn about propagation as almost always you end up breaking a bit off as they are quite fragile. But, do not despair as you can now grow yourself a new plant! I normally chuck my leaves and bits in a tray or cardboard box in the shade. From 2-6 weeks you will see baby plants and roots begin to sprout. Then I take the leaves and lay them on some potting mix in a tray and the stalks I plant. Put into a bit more light and water when the potting mix is dry. Within not too long you will have new plants.

BOOKS

Succulents and Cacti are a huge subject, and you will not find any books that cover everything. Most are specialised in various species, but not many go into the hybrids as new ones are being grown all the time. eBay, and Abebooks are always good for finding books at a good price.
I can recommend anything by Debra Lee Baldwin and also anything by Attila Kapitany.


WEBSITES


This is the best source of information online.

Another good website is a Russian one

Be very aware that many photos of plants online are not ID’ed correctly, even the online stores selling them have incorrect ID’s, so don’t assume anything without verification.
