I get asked a lot how to make a succulent sphere for displaying in the garden. There is something about the shape that appeals to us. Whether they're made from metal, hypertufa or wire, garden spheres add definition, like a punctuation mark in the garden.
They certainly make us come to a complete stop to gaze at them!
I usually use the cheaper wire hanging baskets with the shaped coir liner, as these are easier to plant into than the better quality coco fiber type. Sometimes, cheaper is better.
I found these at a dollar store, but I've also seen them priced economically at larger box stores, in their seasonal department during the summer.
For this project, buy two wire hanging baskets the same size. The ones shown here are just under 30cm (12 inches) across - there are many sizes available, and many shapes.
Find the dome shaped ones - any other shape won't make a globe.
I have used bigger ones, but they are accordingly heavier to display and move, so they can only be placed on a sturdy frame or terracotta pot to show them off.
Hanging them requires extremely strong wire or chain, as well as a sturdy hook to hang them on, as well as a safe place to hang them.
As these get so heavy when wet I choose to display them in a large planter or pot so they look like a topiary.
The smaller sized ones can be hung from chains, or wired to support the weight of the filled sphere from underneath. I’ve also seen smaller ones yet with a pole stuck into the bottom of them which look like topiary trees.
Choose 2 identical
...fill with potting soil
...which will hold the soil when you join the two baskets together
So, you have your two wire baskets. I fill them with Sunshine mix #4, which has extra aggregate in it for drainage. Keep in mind that this will eventually break down, and hold too much water, but for a season or two, your succulent sphere will be gorgeous. Pack the soilless potting mix tightly, so it fills the space entirely - leaving pockets of air makes the liner sag eventually as the coir fiber softens.
Place a piece of plywood or a thin metal plate over top of one of the baskets, then flip it over onto the top of the other one. Carefully draw out the plywood or metal, so the soil stays in place.
Wire the two baskets together at their rims in at least four places.
Match up the pattern
...wire them together with a short piece of
Plant with Sempervivum chicks - voila!
Collect enough Sempervivum chicks with a short piece of stolon still attached to hold the chick in place until it roots. Make a small hole in the center between where the wire basket pieces cross over. Squeeze the Sempervivum chick stolon into the small hole.
Eventually, you will have to replace chicks or guide new chicks to take root in any blank spots. Use many different kinds of Sempervivum for a mosaic appearance, or only two or three for more impact.
If you have chicks with no roots or stolons, pin them in place with a toothpick or piece of wire bent in half like a hair pin.
Late July is the best time to make your Sempervivum sphere, as there are lots of chicks forming at that time of year; as well, there is time for the chicks to root before winter.
To over winter your succulent sphere, if you’ve used Sempervivum as I recommend, the winter care is easy.
Take the sphere down if it’s hanging and place it in a corner of the garden where it won’t get disturbed, and cover it with leaves; if you get some snow, even better.
This protects the plants from temperature swings - to prevent damage to the plants, it's important to eliminate the possibility of freezing and thawing.
Once the coldest part of the season is passed, inspect the succulents and replace as needed, fertilize with water soluble fertilizer or compost tea a couple of times per growing season.
Your three dimensional succulent sphere will only get better with age, and eventually you won’t be able to see the wire baskets as they become covered completely by the happy Sempervivum.
Please note: Sempervivum are a hardy perennial, and MUST have a dormant period. Therefore, they won't survive inside your house.
Other tender succulents that will work just as well are Echeveria, Graptopetalum, some of the smaller Crassula, Senecio rowleyanus and many more miscellaneous succulent plants.
The best types of succulents to use for crafts are low growing species and those that form clustering rosettes.
This way, they can cover the surface of the mosaic, sphere or topiary and hide the moss or coir that contains the soil.

Xeric gardens, due to the fact that at times the plants look a little tired of never being watered, benefit from really unique focal points to take the eye away from the bedraggled plants.
