Q: Can you explain exactly what fertilizers do and what I need to look for when buying one?A: It can be a little confusing when so many products are available. All fertilizers have three numbers on the bag, and they always mean the same thing. The first is the amount of nitrogen (produces green growth); the second indicates phosphorus (strengthens stems and produces flowers); the third number is for potassium (keeps root systems healthy).
Q: What types of annuals can I grow together in a container that will sit on my patio, which receives a lot of afternoon sun?
A: Afternoon sun will cook a lot of plants, so you want to make sure your plants have adequate water before the sun hits. And plant selection is important. I suggest salvia, marigold, vinca and petunias.
Q: I've heard the phrase "cutting to the crown" when referring to pruning perennials for the season. What does that mean?
A: The crown is the area on the plant just about the soil, where the stem comes up from the roots. When pruning in the summer for general maintenance, you should not cut to the crown. Instead, cut just under the spent foliage. When cutting perennials back for winter, you can cut close to the ground, but not all the way to the crown. Use a good pair of garden shears, but avoid damaging any growing points on the stems.
Q: Is there an organic method for eliminating Japanese beetles? They invade my roses every year!
A: The best way to kill them organically is in the grub stage. Do this with beneficial nematodes, which are biosafe. This should be done in spring and fall.
