A few things are important before your start. Determine what is the top and bottom side of the bulb, make sure you have the right pot size and potting medium ready and determine where you’ll place the bulbs.
Determine what the top and bottom side of the bulb is.
In most cases you’ll see one or more ‘eyes’ in the bulb. This is the top side of the bulb and should be planted upwards. The bottom is more smooth. If you can’t see any ‘eyes’ on your bulb, no worries. Just plant your bulb in any way. The bulb shouldn’t have a problem to grow out, it could only take a bit longer.
Pot size and potting medium for your Caladium bulb
The ‘Jumbo’ bulb we have for sale can best be potted up in a 17 to 19 cm pot. Plant one bulb per pot. If you do want to plant multiple bulbs in one pot it’s recommended to use a bigger pot so there is enough space between the different bulbs.
Caladium bulbs aren’t too difficult and will grow in most soil mediums. Preferably use a soil that can hold some water on one hand and with good drainage on the other hand. The soil must remain slightly damp, but always avoid too much water is held up in the pot to minimize the risk of rot. If you don’t want the fuss of making your own soil, you can use an all purpose soil for house plants, which is normally available in all garden centers.
Determine the best place in your urban jungle to grow out the bulb(s).
