A: Your picture exhibits mushrooms rising on the trunk, that are the seen, exterior “fruiting our bodies” of fungi. Mushrooms usually reside on useless or decaying natural materials, and produce spores by which these fungi are unfold.
Apart from the seen mushrooms, these fungi have unseen rootlike buildings, referred to as mycelia, extending into the natural materials on which the fungi are hooked up. When these mushrooms seem on tree trunks, mycelia are working internally within the trunk, and are normally an indication of useless or decaying tissue contained in the tree.
Such fungi are usually secondary invaders, coming into a trunk that was beforehand wounded by cracks, winter harm, pruning or different wooden harm. I discover a number of cracks within the trunk and limbs, which could have led to injured tissue and moisture buildup — which was an invite for secondary invading fungi to enter and start the pure wood-rotting course of.
There is not a great way to cease the fungi after they begin their exercise, as a result of the underlying drawback of broken wooden stays. It could be smart to scrape off the mushrooms as finest you may, however the inside mycelium development will nonetheless be there, dwelling on the decaying or injured wooden, and extra mushrooms will finally seem. If any rotten wooden will be eliminated with a pointy knife, it would assist. Fungicides are usually preventative, reasonably than curing fungal issues already entrenched.
Wooden-rotting fungi are part of the cycle of nature, serving to to decompose useless wooden, and when a tree enters this stage, reversal is uncommon. Bushes can reside with this situation for a time, and we see mushrooms rising on bushes in forests. But it surely does sign a critical state of affairs by which such bushes probably received’t reside to a ripe outdated age. I want I had higher information.

Q: Ought to I rototill my vegetable backyard within the fall after it’s cleaned out? — Darwyn S.
A: I feel it’s a good suggestion to rototill the backyard within the fall, nevertheless it’s considerably of a private desire. Autumn is a good time so as to add natural materials like leaves, peat moss or compost, and turning the soil helps the fabric to decompose. Rototilling or spading the soil helps expose bugs and illness organisms that could be attempting to overwinter underground, and turning the soil exposes them to attainable winterkill.
Fall tilling tends to make the soil extra workable within the spring, particularly if the soil is heavy. Some gardens are profitable with a no-till kind of operation, and that’s an more and more profitable development. I nonetheless favor fall and spring tillage for my very own backyard, partly as a result of I get pleasure from rototilling and the aroma of freshly turned soil.
Q: We planted a purpleleaf sand cherry bush about 5 or 6 years in the past. I didn’t notice how briskly and the way a lot it grows yearly. I’ve been trimming it again a minimum of 12 to 18 inches each spring after it bloomed. It has all the new development on prime and only some new branches on the backside. Is there something I can do to drive it to fill out on the backside? I learn that I can reduce it again within the early spring, however can I do this because it’s been within the floor this lengthy? — Yvonne R.
A: Your purpleleaf sand cherry will rejuvenate properly, and will be accomplished periodically even when it will get a lot older and wishes occasional re-working. Though it was planted 5 or 6 years in the past, you may reduce all of it the best way right down to about 6 inches above floor stage round April 1 earlier than new development begins. That is the very best time for such rejuvenation pruning.
Rejuvenation pruning will encourage vigorous new branches to sprout from the decrease trunks, making the shrub fuller. As a result of these shrubs develop shortly, this rejuvenation will be accomplished each 4 or 5 years, or each time it seems to be “leggy.” Spring is the popular time for this, reasonably than fall.
