Dear Heloise >> In response to recent hints regarding credit card protection, I have my two cents to add: We have recently had our major credit card cancelled and replaced three times in three months! This is such an inconvenience. I asked the credit card company what we could do to prevent future problems related to fraud. The fraud seemed to be coming from in-person purchases. So, they suggested two things:

• Always tap the card on the credit card machines (instead of inserting or sliding the card in), if available.
• Cover your account number on the front of your card with a piece of tape (like blue painter’s tape or masking tape that can be easily removed, if needed). The reasoning behind this is to prevent anyone near you from snapping a photo of your card during the process of a transaction. There are cameras everywhere, as well as unscrupulous people.

Since we’ve started tapping the card during purchases and keeping the account number covered, we have not had fraud problems for the last few months. Hope this helps someone else!

Dear Readers >> When you water plants, soak the soil thoroughly when watering. A sprinkling of water can cause roots to come to the surface and get baked to death by the sun. The idea is to get the roots to go down deep where they won’t be subjected to summer heat. It’s best to water plants early in the morning so that their leaves will dry in the sun.

When leaves stay wet all night after an evening watering, spot diseases may occur.

Dear Heloise >> I am an 88-year-old man, and I have trouble opening jars. But I have found a paint can opener that works great! I just place the opener in the indented area of the lid and gently press down. The seal easily gets broken.

Dear Heloise >> I read your hint about having old photos digitized. There is an app called Photomyne, which works wonderfully and allows you to digitize your photos for free, minus the nominal cost of the app.

Also, if any of your readers are Amazon Prime members, they might have unlimited storage space for photos.

Dear Heloise >> Years ago, a good friend told me about a great aluminum foil idea. Whenever using a crockpot or roaster, place tinfoil between the lid and pot. Steam won’t evaporate. Just be very careful when removing the foil. The steam is hot!

Dear Heloise >> So many of my friends complain that they need to keep their kids busy during breaks from school.

When my neighbor had a new refrigerator delivered, I asked if I could have the box. They were glad to get rid of it, and I was thrilled to get it. I took it home and gave it to my kids, along with crayons, colored pencils and stickers. They had a blast coloring both the inside and outside. Now they lay claim to all the boxes we get and draw on them. It keeps them busy and encourages creativity.
