Can I use Roundup to clear before planting?

Looks like the answer is yes! Allow 3 to 7 days after application depending on the product and the plant.

Roundup Weed and Grass Killer Concentrate Plus can be used to prepare an entire vegetable garden plot or remove a lawn, while Roundup Ready-To-Use Weed and Grass Killer III works well on smaller jobs. You should wait a minimum of three days, from the time of the last treatment, with either of the products, to plant edible plants like vegetables and herbs or fruit-bearing plants.

At planting: Trifluralin (Preen Garden Weed Preventer, Miracle-Gro Garden Weed Preventer, or other labeled formulation). Apply at seeding of broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, collards, black-eyed peas, field peas, garden peas, lima beans, mustard greens, snap beans, and turnip greens. Apply before transplanting celery, broccoli, Brussels sprouts, cabbage, cauliflower, eggplant, peppers, onions, and tomatoes. Apply to established cantaloupe, cucumber, and watermelon that have at least four true leaves. Apply to established asparagus prior to spear emergence. Apply after planting potatoes. Trifluralin will not control existing weeds. It does provide pre-emergence control of annual grasses like crabgrass, foxtail, and goosegrass, and small-seeded broadleaf weeds like purslane and pigweed.

Mac OS "Open with..." "Fetching..."

Aberrant behavior in Yosemite: Right-clicking on a file and choosing “Open with...” from the popup incurs a long delay while Mac OS is “Fetching...” the list of apps for that file type.

Fix: Run the following terminal command:

Plant Germination Supplies

A quick survey of the supply shelf shows I have

68 3-inch starter cups
70 5-inch starter cups
216 peat pellets

and more trays and lids than I shake a stick at.

Last year, I tried to get the timing just right - last frost date for my zip code, subtract the number of days for germination, add a week for growth/hardening off, and germinate accordingly. It didn’t work very well, as the seedlings were still just wisps and the punishing rain that came along right after transplanting was too much for them.

This year, I’m going to err on the side of gangly, strong seedlings, so I think I need more 5-inch starter cups.
