<table border="0">

|

<td><p class="center larger"><i>You want to re-turf the garden</i></p>
|
|
<p class="center larger">Let us try and find out what it will cost!</p></td>
|
|
</tr>
|
|
</table>
|
|
<p>Your first step is to find the area. The <a href="garden-area.html">Garden Area Activity</a> shows you how.</p>
|
|
<table width="50%" border="1" align="center">

<td><p class="larger">Area of Garden m<sup>2</sup> (or ft<sup>2</sup>):</p></td>
|
|

|
</table>
|
|
<p>Now, you have two choices:</p>
|
|
<ul>
|
|
<li>buy <b>seed</b> (and enjoy watching the grass grow), or</li>
|
|
<li>buy <b>turf</b> (and get instant weed-free results)?</li>
|
|
</ul>
|
|
<p class="larger">Let us work out the cost of each.</p>
|
|
<p><i>Note: I include sample values, but you should use your own garden area, and also find out the cost of seed and turf where you live.</i></p>
|
|
<p> </p>
|
|
<img src="images/grass-seed.jpg" width="118" height="167" style="float:left; margin: 20px; " alt="grass seed" />
|
|
<h2>Seed<br></h2>
|
|
<p>How much grass seed should I order? <br></p>
|
|
<p>You've already calculated the area of your garden, so now you will have to find out how much seed will cover each square meter, or each square foot.</p>
|
|
<p>This might also depend on which kind of grass seed you want to use, so you will have to decide that first.<br></p>
|
|
<p>You could visit your local garden center or farm supply store and read the instructions on the seed packet, or ask the store keeper for advice. Write down your choice here:</p>
|
|
<table width="50%" border="1" align="center">
|
|
<tr>
|
|
<td><p class="larger">Type of Grass Seed:</p></td>
|
|
</tr>
|
|
<tr>
|
|
<td><p class="larger">How Much Seed per m<sup>2</sup> (or ft<sup>2</sup>):</p></td>
|
|
</tr>
|
|
</table>
|
|
<p>While you are at the store, collect some prices.</p>
|
|
<table width="50%" border="1" align="center">
|
|
<tr>
|
|
<td align="right"><p class="larger">Packet Size:</p></td>
|
|
<td width="70"> </td>
|
|
<td width="70"> </td>
|
|
<td width="70"> </td>
|
|

|
|
<tr>
|
|
<td align="right"><p class="larger">Cost:</p></td>
|
|
<td> </td>
|
|
<td> </td>
|
|
<td> </td>
|
|
</tr>
|
|
</table>
|
|
<p><br>
|
|
Now you've got all the information, what kind of calculation will you need to do? <br></p>
|
|
<div class="example">
|
|
<h3>Example:
|
|
The area of my garden is 41m<sup>2</sup><br></h3>
|
|
<p>I found out from the local garden center that I will need 55g of seed for each m<sup>2</sup>.</p>
|
|
<p>So the total amount of seed I will need is:</p>
|
|
<p class="center">41 × 55g = 2,255g</p>
|
|
<p>But the area calculation was only a rough estimate, so maybe I need to buy, say, 5% extra.<br></p>
|
|
<p class="center">That makes 2,255g × 105% = 2,368g</p>
|
|
<p>Or about <b>2.4 kg</b><br></p>
|
|
</div>
|
|
<div class="center80">
|
|
<p class="center larger">Tip: Always order a little more than you need!</p>
|
|
<p class="center">Just in case your estimate is wrong, or some gets wasted.</p>
|
|
</div>
|
|
<p>Suppose the garden center only sells seed in 500g or 1kg packets. How many packets do I need to buy, and which is the most economical?<br></p>
|
|
<p>I could buy:</p>
|
|
<ul>
|
|
<li>Five 500g packets</li>
|
|
<li>Three 500g packets and one 1kg packet</li>
|
|
<li>One 500g packet and two 1kg packets</li>
|
|
</ul>
|
|
<p>Which do you think is the cheapest way of doing it?<br></p>
|
|
<p>Maybe the third choice is the cheapest. It's usually more economical to buy larger quantities.</p>
|
|
<p>But watch out! Sometimes they might sell the smaller quantity at a special rate as a special promotion. Also check out the prices of different brands to get the best bargain.<br></p>
|
|
<h3>Too Much?</h3>
|
|
<p>But won't that be too much seed? <br></p>
|
|
<p>Yes, of course you will have some seed left over (unless you are very lucky), but you can keep some in case you need to reseed part of your lawn another time, or in case the birds ate some of the seed!</p>
|
|
<h3><br>
|
|
How much will it cost?<br></h3>
|
|
<p>Once you know how many packets of seed you need, and what sizes, you can calculate the cost of the seed. That's easy. <br></p>
|
|
<div class="example">
|
|
<h3>Example: A 500g packet of seed costs $20 and a 1kg packet costs $35.</h3>
|
|
<p><br></p>
|
|
<div class="tbl">
|
|
<div class="row"><span class="left">I need one 500g packet, so 1 × $20 =</span><span class="right">$20</span></div>
|
|
<div class="row"><span class="left">I need two 1kg packets, so 2 × $35 =</span><span class="right">$70</span></div>
|
|
<div class="row"><span class="left">The total cost is:</span><span class="right"><b>$90</b></span></div>
|
|
</div>
|
|
<p> </p>
|
|
</div>
|
|
<p>Your Turn:</p>
|
|
<table border="1" align="center" cellpadding="5">
|
|
<tr align="center">
|
|
<td class="larger">Packet Size</td>
|
|
<td class="larger">Quantity</td>
|
|
<td class="larger">Cost Per<br>
|
|
Packet</td>
|
|
<td class="larger">Total Cost</td>
|
|

|

|
|
</table>
|
|
<p>Note: you might have to do the calculations using square feet, and find out the costs of different sizes of packet in 1lb packets and 2lb packets. But the idea's the same.</p>

|
|
|
|
<img src="images/turf.jpg" width="200" height="141" style="float:left; margin: 20px;" alt="turf" /><h2>Turf</h2>
|
|
|
|
<p>Some people prefer to use turf instead of seed. It may be easier and quicker to lay, but will it cost more?</p>
|
|
<p>The calculation should be fairly simple. First of all, decide which kind of turf you need.<br></p>
|
|
<p>Then all you need to know is the cost of 1m<sup>2</sup> of turf (or 1ft<sup>2</sup> of turf). Again, you should be able to find out this information from your local garden center or farm supply store.</p>
|
|
<div class="example">
|
|
<p>Example: I found out from the local garden center that turf costs $4.20 per m<sup>2</sup></p>
|
|
<p>I have an area of 41m<sup>2</sup>, but this was only a rough estimate, and I may lose some when cutting it to shape, say 10% extra.</p>
|
|
<p class="center">That's 41m<sup>2</sup> × 110% = 45m<sup>2</sup></p>
|
|
<p>Then the cost of turfing my garden is 45 × $4.20 = <b>$189.00</b></p>
|
|
</div>
|
|
<p>For me it costs about twice as much as seeding, but this is just an example. Try it for your own garden.</p>
|
|
<table width="50%" border="1" align="center">
|
|
<tr align="center">
|
|
<td width="33%"><p class="larger">Turf
|

|
|
<p>Note: you might have to do the calculations using square feet, and find out the cost per 1ft<sup>2</sup> of turf.</p>

<p> </p>

<p>Now you know the cost of both choices, which do you chose?</p>
