As you are working in the garden, don’t forget your eye protection.
It is a chore to keep plants in pots watered and looking nice during the hot summers as well as through the winter. I have found self-watering pots to be useful in helping me without a lot of work on my part. (I'm basically lazy.)
When we decided to replace the fountain in our sunroom, we thought of another use.
We travel during the summer and need a watering system to take care of our hanging plants and small potted plants in our sunroom.
When my indoor plants bloom, DH and I like to take photos of them. Sometimes it is difficult to obtain a good photograph of them without a proper backdrop.
We recycled our old wet/dry shop vac into a planter. There was a threaded drain at the bottom which we did not tighten fully so that water could drain out. The blue also adds color to the yard.
Grow a pineapple plant. Twist the top off a fresh pineapple and remove the lower leaves. Let the bottom part of the pineapple dry out for several weeks. then plant. Be warned that the leaves do have sharp thorns on the ends.
Dry your hydrangea blooms for a winter arrangement. Cut the blooms when they are fully mature, leaving a stem. Pull all the leaves off the stem and place stems in a vase -- no water, and the hydrangea bloom will soon dry and can be used in an arrangement.
Recycle plastic trays and gallon Ziploc bags to make a mini-greenhouse for rooting plants. These are especially good when using damp sphagnum moss for rooting as it tends to dry out quickly. I rinse the trays and and bags and keep a supply on hand. You can write the contents on the bag with magic marker so you won't have to guess what you're rooting. Monitoring your greenhouse is simple with the clear bags.
Instead of purchasing those pricey compost containers, I use plastic coffee cans. The lids fit tight so you don't attract fruit flies and you don't have to buy deodorizers either.
For those weeds that have tiny stems and are hard to grasp with regular gardening gloves, I use nitrile disposable exam gloves. Although I'm not allergic to latex I prefer the nitrile gloves.
