Sharon Hull, This Week from the Garden
This column started out in 2003 as a brief bullet-type collection of exactly what garden jobs were appropriate to perform that the week the column was printed, so was known as This Week from the Garden. Though it evolved into something quite different (and more ), the title stuck. So with this guide, I’m returning to ancient days and talking some garden actions we ought to be focusing our attention on in late February.
Apply dormant oil spray to deciduous fruit trees and roses before they start to bloom or leaf out. Once the leaves or blossoms start to start (the shrub emerges out of the dormant state), it’s too late to use dormant oil. (Note which apricots should rather have a copper spray fungicide applied as the flower buds available. See homeguides.sfgate.com/apricot-tree-care-49820.html for information.)
If fungal infections have been a problem this past year and when your trees and shrubs currently have buds and leaves appearing, as is true within my garden, employ instead a biofungicide such as Revitalize. (It substituted the merchandise Serenade that you might have relied on previously, but functions essentially the exact same style, to activate the plant’s natural immune response to fight off infection organisms.) Follow the container’s instructions. If you initiate the program schedule today, it is going to be more powerful than if you delay.
Prune back perennials and split as needed. Those people along the shore will probably not undergo a frost by today so it’s very safe to remove the older expansion on tender plants.

Keep irrigating container crops ! With considerably lower rainfall than is deemed normal and not one in the immediate prediction as I write this, plants may dry out incredibly quickly. Add the rainy times we’ve been experiencing lately which pulls moisture from these leaves, and also our container crops particularly can endure – may also die – if we don’t provide them regular watering. Monitor plants from the ground also, particularly when they were implanted this season. Their root programs will continue to be small and not able to draw moisture from deeper into the soil.
While they’re in bloom, select deciduous flowering crops. Hardy woody trees and shrubs can offer the “bones” of a landscape layout, even following their spring blossoms fade. But to make sure you understand what you’re purchasing, pick them while they’re prospering. Plants like flowering quince, cherry, crabapple, lilac and witch hazel have been in blossom now or shortly will be.
Prune back summer flowering shrubs as suitable. Start using a comprehensive review to search for bird nests. If you discover a nest, wait to prune that specific tree until following the young birds have fledged. If no parts are located, proceed: first eliminate any dead, dying or damaged branches, then prune for mold and also to encourage strong new growth.
Be aware nevertheless: spring bloomers must be pruned just after their blossoms fade, to prevent cutting off the flower buds. This information is frequently expressed another way: plants which bloom on new wood are pruned in the spring, whereas plants which blossom on wood generated last year aren’t pruned until after they bloom. Have I totally confused you? Here’s one great website that explains the fundamentals: bhg.com/gardening/trees-shrubs-vines/care/what-to-prune-when/.
Install trickle irrigation methods until the backyard becomes too lush to readily work from the beds. Now, while crops are dormant or still quite modest, it is possible to lay a trickle method without damaging them. Once they fill out, it gets much more challenging to prevent stepping on them accidentally beating them since you put out the distribution lines of a trickle system.
