To use hoarded garden materials needs a plan.

p.s. Remembered I have some small bungie straps. Have
got them ready this morning to tidy my canes so they are all in their respective sizes in the large tub, instead of leaning over over the place.

Diane your cacti will not need feeding for quite a long time and certainly never in winter. I have never fed mine as a routine, just perhaps once in the growing season and/or after flowering. When you pot them on again you might like to try a purpose mix for cacti - you can buy quite small bags of it in garden centres.
How often you water depends on room conditions more than the calendar. Once a month lightly in winter is OK but don't soak them or feed them and never let them stand on a tray with water in it for longer than it takes for the compost to become damp. In the summer you can up it to fortnightly if the weather is warm and dry. More cacti are killed by kindness than by neglect as they are designed for harsh conditions.
I hope they do well for you. Do you know their names?

This advice is in total contrast to what I have learned.
I shall soak them on the 14th of every month with tepid rain water including nutrients, during the summer, to see what happens.
One is looking jolly already. Its most interesting.
I have enough trouble remembering music without bothering with Cacti names !
If they want to flower they will.

Just thought your little plants might have labels...

The advice was just passing on what I have always done, which I first learned when I was a member of the National Cactus and Succulent Society 50 years ago. I still have my prize tickets. In essence its not very different from what you are doing, except that an experienced grower will water etc depending on the look of the plant and the compost rather than a date on the calender, which is meant as helpful guidance for beginners.

Soak and dry out in summer, water very sparingly in winter and don't feed during winter unless you have Christmas cacti which need different treatment.
