There are some exceptions such as Golden Delicious apple and Stella sweet cherry that are self pollinating, and one tree is sufficient. Apricots, tart or pie cherry, European plum, peach, nectarine, blackberry, raspberry, currant, gooseberry, grape and strawberry plants are all self pollinating and only one tree or plant is adequate for pollination and fruit development. Place the bouquet in a container of water and hang it on the sunny side of your tree that needs to be pollinated. The bees will move from the flowers in the bouquet to the flowers in the tree and pollinate them. The trees must be blooming at the same time and the bouquet should be replaced every 2 or 3 days to keep the flowers fresh and the pollen viable.
Many gardeners have problems keeping grassy weeds out of iris.
This means that an applicator can spray over the top of an iris bed without hurting the iris. Poast and Fusilade II are relatively slow acting and it may take over a week for the grasses to start dying.
