Trees have small, absorbing roots that are close to the surface of the soil and extend out from the tree three to fives times the width of the tree canopy. Deep cultivation around trees can damage these roots. Keep mulch around trees to 4-6” depth; thicker mulch layers can suffocate roots.

Tomato seedlings with five to seven leaves are ready to transplant into the garden. Plant the tomatoes deeply with only a few leaves above ground. Lay the plant in a shallow trench, bending the stem so only the top is out of the ground. Remove any of the leaves below the soil level and fill in the trench. New roots will sprout along the stem

Post-emergent herbicides can control broadleaf weeds like dandelions, clover, thistle and bindweed but will not prevent weed seeds from germinating and re-infesting your lawn. Indiscriminant use of herbicides can cause problems for trees and other landscape plants and may actually reduce the vigor of the lawn.
