Hopefully your heat-tolerant, drought resistant varieties won't clamor for water. While the plants are getting established on the rooftop though, they will probably need more water than for the remainder of their growing life. If it's raining, assume that's the watering done for you.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/5\/5c\/Build-a-Green-Roof-Step-10Bullet1-Version-2.jpg\/v4-460px-Build-a-Green-Roof-Step-10Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb\/5\/5c\/Build-a-Green-Roof-Step-10Bullet1-Version-2.jpg\/aid688104-v4-728px-Build-a-Green-Roof-Step-10Bullet1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} Check blockages quickly and mend them; any backup of water being unable to escape can result in roof landing inside your home.

One-sentence summary -- Water only if needed. Keep a regular check on drainage.


These are little balls filled with seeds. You leave them in bare areas, and the seeds will sprout, leaving plants growing in the area. Use plants native to your area so you don't encourage new species that will try to take over.  Mix 1⁄2 ounce (14 g) of native wildflower seeds with 3.5 ounces (99 g) of potting soil. Add in 1.5 ounces (43 g) of dry clay, such as red powdered pottery clay. Mix the ingredients together. Slowly add in water until you have a thick paste. Roll the paste into balls, and let it dry on a cookie sheet covered in wax paper. Leave the balls in areas where the ground is bare. The balls will break down and sprout plants when it rains. Have everyone bring in t-shirts or buy enough thrift store t-shirts for everyone. Cut the sleeves off the shirt, and then cut around the inside of the neck. The bits you have left at the top are the handles.  Turn the shirt inside-out. Mark a line across the bottom that's about 4 inches (10 cm) up from the bottom. Cut strips that are 1 inch (2.5 cm) wide by cutting up until you reach the line. Tie each set of 2 strips together, one each from the front and the back. Then go back and tie each set together by taking one strand from one set and one from the next set and knotting them together. Turn the bag inside-out again. Start with an empty toilet paper roll or paper towel roll. Poke a hole in both sides of the tube at the top, and run a string through them. Tie the string above the roll. Using a butter knife, coat the roll in peanut butter. Coat the tube in bird seed by rolling it in a plate filled with seed. Hang your bird feeder outside using the string. Start by making strips from plastic bags. Lay a bag out flat and cut the top off, including the handles. Cut the bag horizontally into strips. Tie the strips together. You'll need 12 long strips, and they should be a bit longer than you want your jump rope to be. Tape 6 strips together on one end.  Tape the 6 strips to the back of a chair, and braid them together. Tape the other end. Do the same with the other 6 strips. Tape the other end. Pull them off the chair. Tape the 2 sets together on one end, and then tape it back to the chair. Twist the 2 braids tightly together, and then tape them together at the other end. The tape forms the handles for the jump rope. Pull the taped end off the chair.

Place the 2 edges that you’re going to seam together in close proximity—roughly 1–2 in (2.5–5.1 cm) apart. This will give you enough space to apply the 2-part epoxy to the edges, but also make it easier to squeeze the pieces together quickly. This also gives you the opportunity to take one more look at how well the 2 pieces match up. Buy a kit with rubber suction cups and metal turnbuckles (which look like very long bolts) that are intended for clamping countertop seams. For each pair of suction cups, thread a turnbuckle through the openings in the top by turning it clockwise. You want the suction cups to be spaced about 4–6 in (10–15 cm) apart on the turnbuckle so you’ll have room to work between and beneath them.  2 pairs of suction cups and 2 turnbuckles should be sufficient for most countertop seams, but you can use 3 or more for longer seams. You can also buy or rent a tool known as a “seam puller” or “seam setter” that uses vacuum pumps to pull and hold the granite pieces together. If you choose one of these, follow the instructions for proper use. Think of it as placing 2 or 3 “bridges” over the seam, with each turnbuckle serving as the bridge span and the suction cups as the bridge piers. Try to space the suction cups an equal distance from the seam—roughly 2–3 in (5.1–7.6 cm) each.  Make sure the suction cups stick well to the granite. Try moistening the underside of each cup with a damp fingertip if needed. After you apply the 2-part epoxy to the seam, you’ll tighten the turnbuckles to pull the pieces of granite tightly together.

Lay the 2 pieces of granite side-by-side. Thread turnbuckles through 2-3 pairs of suction cups. Stick each pair of suction cups on either side of the granite seam.
