Answer: Most cactus like several small feeding, better than one large feeding. I like a time release type in the spring and this will feed the plant for six or more months. The other way is to give the plants food three time a year (spring, summer, fall)with a dilute solution of plant food like (5-10-5). This should do them well for the year.
Yuccas are usually pruned in the spring, just as new growth begins. Simply cut away the old, dead foliage to make the plant more attractive.
Best wishes with your cactus garden.
