Gardening Question?

my mom has been watering her plants and they look like they are drying out, and the leaves are turning yellow. What Is Wrong with them why are they turning yellow? (oh yea they are hibiscus
Gardening Question?
Whereabouts in the world are you?

Hibiscus need lots of sunshine and humid conditions - although the roots should be kept on the dryer side. So water every 3-4 days but use a hand mister every day to just dampen the area around the plants.

Yellowing could just be due to natural die back but without knowing more it is a bit hard to tell you!

Have a look at this site for more info

Reply:If your mom likes tropical flowering plants, maybe she should try something easier to grow, like plumeria. They don't need to be watered in most climates, they tolerate lots of sunshine, and they have beautiful fragrant blooms. They can be grown from just cuttings, too. And they can also be grown as a potted plant or in the ground, depending on where you live.



If you think she might be interested in plumeria, this Yahoo group can give you some information on how to grow them and how to get them inexpensively.

Reply:it depends on whether they are in door or out doors. look for small spider web like on the plant, these are spider mites and that could be the problem use special soap and water to cure that or overwatering..dont let a hibiscus soak in water also fertilizer during their growth period March-October will help choose one with a low phosphoros. or it could be nothing all hibiscus get yellow leaves a few only mean it is a natural thing but more then a few can be caused by stress like replanting....
Reply:Too much or to little water can make the leaves turn yellow. Also clorosis will make the leaves turn a blochy yellow. Or needs muratic acid added to the soil. Aphids sucking out the plant juices will make the leaves turn yellow. Call your local county extension where they have master gardeners available to look at the samples you bring in for them to look at and they can make the proper diagnosis.
Reply:They could be over-watered, so the root is rotting. Have your mom cool it with the watering for a day or two. The best way to check moisture in the soil is to find a small, dry stick (like popsicle stick, or twig) and place one end in the soil, about halfway down. Let it sit for about 5 mins then remove it. If the soil on it is dark brown and the stick is a different color from the piece exposed to air then there is enough water. If the stick looks the way it did when inserted and the soil is dry and light gray/brown, it needs watering.

Is the plant getting too much sun? Perhaps it is meant for shade, or light sun instead of full exposure. Check this out as well and try moving it around instead of keeping it under the hot sun.

Also, get a cheap soil test from Home Depot, Lowes or any Garden Center. (They are like $3). Your soil may need nitrogen or PH. If needing nitrogen, mix used coffee grounds into the soil (Starbucks gives these out for free) and hopefully things will perk up, no pun intended!

Good luck!
Reply:Maybe they need to be fertilized? It could also be from too much watering, Or not giving them a big dose of water. You should water every couple of days, but a real good dose. Not a little each day.
Reply:over watering, let them dry out, buy a food especially for hibiscus and follow the directions on the packet, hope they recover.
Reply:Maybe they need feed you can buy Hibiscus feed at wal-mart.
Reply:They are lacking nutrients a good fertilizer such as
