Tribulus terrestris is an annual plant in the caltrop family (Zygophyllaceae) widely distributed around the world. It is adapted to grow in dry climate locations in which few other plants can survive. The stems radiate from the crown to a diameter of about 10 cm (3.9 in) to over 1 m (3 ft 3 in), often branching. They are usually prostrate, forming flat patches, though they may grow more upwards in shade or among taller plants.
Water every 1-2 weeks, allowing soil to dry out half way down between waterings. Expect to water more often in brighter light and less often in lower light.
Calathea do not need a lot of fertilizing, but they will flower and do well with standard houseplant fertilizer during spring, summer and fall. They especially need fertilization during periods of growth and flowering.
Calathea enjoy moist soil—but not wet soil. Try a mix of 50 percent potting soil, 20 percent orchid bark, 20 percent charcoal, and 10 percent perlite. They also dislike being dried out. Every few days, stick a finger in the soil to see if the medium feels dry.
Pruning or deadheading old or faded blooms improves your calathea's appearance and channels its energy into producing new foliage and blooms. Even though the calathea blooms are often indistinct and may be barely noticeable, regular deadheading gives your plant renewed vigor.
Temperature – Calathea plants do not like the cold very much. They are from tropical areas of the world and prefer temperatures between 65-80 degrees.
If you are looking for a pet-safe houseplant that may be a bit more green and leafy, then try our Calathea. Known as a prayer plant because its leaves fold together, this is a perfect non-toxic plant for your furry friend and easy to look after too. Like a lot of low light plants, Calathea tend to grow fairly slowly. They are considered to grow at a moderately fast rate, but they will not grow and spread out over their pots and become a problem. In fact, Calathea plants usually will only grow to about 2 feet in height and then stop.
