Unfavorable weather is a strong enemy of healthy gardenias. Bouts of hot weather, coupled with insufficient watering, hinder gardenias from flowering. As plants transpire, they lose water through evapotranspiration -- a collaborative effort of soil evaporation and foliage transpiration. When gardenias are in bud, they require additional water to sustain plant health. A 2- to 3-inch layer of mulch not only conserves moisture but also protects sensitive gardenia roots.
Clemson Cooperative Extension recommends drip irrigation for gardenias and advises that plants should be watered even after flowering to strengthen them for winter weather.

I wouldn't water them more than once every two or three weeks. They grow in the deserts of our Southwest with infrequent rain. If you want them to get larger, water them every two or three weeks with 10 or 15 gallons of water. But cacti should never be irrigated frequently. I'm guessing the barrel cactus is rotting internally. Sometimes they will develop holes in their sides from rotting. They can take a lot of internal rot before they finally collapse and we see the damage.
Question: I have an almond tree. It was here when I bought the house last year. It didn't have any nuts last year. But this year it has tons although it has been dropping what seems like way more than it should.
Also the nuts have a weird sap discharge. Answer: The squiggly sap or discharge coming from your almonds is from insects that pierce the young nut with their hypodermic-like mouthpart.
These insects can insert it into leaves or fruit and suck out the juices for nourishment. Insects that cause this kind of damage can be can be leaffooted plant bug, stinkbugs or Western Boxelder bug to name three. If enough of them attack fruit or nuts, it can cause the nuts to drop from the tree due to the damage.
Look for them on your fruit trees and spray with an insecticide or soap and water sprays. Soap and water sprays need to be applied weekly or twice a week. Insecticides are sprayed less often because they leave a poisonous residue on the plant. Question: The leaves on my peach tree started looking a bit unhealthy. The newer growth looks a bit strange, distorted and yellow and little brown spots as well.
This new growth looks like maybe too much water. Keep the soil moist but not wet. Fertilize gardenias with a dilute solution of any flowering houseplant fertilizer. Use a product for acid loving plants if possible. Group your gardenia with other plants and place it on a gravel tray to increase humidity and improve bud retention.
Just fill the plant saucer with pebbles and water. The pot should sit on the pebbles above not in the water. As the water evaporates it increase the humidity around the plant.
