The succulents that I bought many months back were finally placed in my empty planters.
Here's how I did the job with much help from our 'manang':
1. Fill the bottom of the planter with gravel until it's 2" deep.
2. Next, cut the cloth filter to size, covering almost the top of the gravel bedding.
3. Place another 2"-3" deep of soil mix.
4. Plant the succulents, preferably one of each variety, for a more natural arrangement.
After an hour or two, they are now all lined-up in our balcony.
