You can place your ponytail palm plant outside when it's warm or when you live in a warm climate.
Although if it gets cold you need to move the ponytail palm back inside for it to thrive as the cold weather can kill the ponytail palm.
A ponytail palm is an indoor plant although if you live in a warmer climate then you can plant and grow the ponytail palm outdoors as well.
If you live in a very warm climate like that found in U.S.
Department of Agriculture plant hardiness zones 9 through 11, growing ponytail palm outdoors is entirely feasible.
They can grow to 30 feet (9 m.) tall, but rarely do as houseplants.
When caring for a ponytail palm the ponytail palm should be watered once every two weeks.
The bulb at the base of the ponytail palm stores water for the plant.
If your plant is hydrated, then the bulb looks filled and lively.
However, if the bulb looks wrinkled, deflated, or shrunken, the plant needs water.
Hence, if you notice a shrunken deflated bulb, your plant is thirsty!
Bottom watering a ponytail palm is a good way to water the ponytail palm.
You can also just simply water the ponytail palm from the top like you do other plants but just don't over water them.
The ponytail palms can go long periods without water.
Allow the top 2 to 3 inches of soil to dry out between waterings and then give the plant a good soak.
You should not water plants everyday as plants don't require a daily watering and it could cause over watering of the plants which can do more harm than good.
Instead do a deep watering every few days or 2 to 3 times per week.
Also only water the plants in the early morning hours or evening hours after the sun goes down during the summer.
You need to create different zones, so plants with similar needs go together.
Water deeply one or two times a week instead of short spurts every other day.
Watering every other day for 15 minutes at a time may be convenient for you, but it can be disastrous for your plants.
Frequent shallow watering causes a plant's roots to grow near the soil surface, where they quickly dry out.
If you have a potted plant, slowly pour water to the base of the stem; let the soil absorb it and wait for the excess water to exit through the drainage holes of the pot.
This is to make sure that every single root of the plant gets water.
If your plants have yellowing leaves and old leaves, as well as new leaves that are falling at the same accelerated rate, you are overwatering.
In most cases, your overwatered plant will recover in 7 – 14 days if you follow the steps above.
If there was extensive damage, it may take longer.
But if there were enough healthy roots, it usually only takes about two weeks to see improvement.
If you are unsure how long to water new plants, aim for 30-60 seconds for small plants – longer for larger plants while moving the hose to a few locations around the plant.
Avoid watering when the soil feels moist.
