There are oodles of greenhouse kits that are easy to install. The most important rule before building a greenhouse is to build one larger than you think you need. You will fill it up fast. Obviously, there are other considerations like site and light, heat and water. A greenhouse might seem extravagant, but if you consider freeing up the garage for the cars and what a garage costs, a greenhouse could be a bargain.
Gardeners appreciate any tool.
I've never known a rose grower or really anyone who would frown when given a new pair of pruning shears. Having another pair of Corona or Felco pruning shears for some is like having a Certificate of Deposit. This time of the year is a great time to curl up on the couch with a good gardening magazine. If you haven't checked out the newsstands or bookstores lately, you will be surprised at how many magazines there are. If you are worried that getting a subscription would cause your gift not to arrive in time here is an easy way to have success.
