I read a few interesting things this weekend, that I thought I'd pass along.
If you want your lilacs to bloom like crazy next year, don't let them go to seed on the tree, cut off ALL the blooms before they go to seed and next year you will see more blooms than ever.
Problems with aphids? Put tin foil around the bottom of the plants insetad of mulch. It reflects light up to the bottom of the leaves and makes it all an undesirable place for the little critters.
Plants looking a little sad? Go to your local nursery and ask if they have bags of worm castings. Your plants will go nuts for this and perk right up.
