Buy yourself a window box..or build one and fill with good moisture retentive potting soil. Chives, parsley, thyme, basil , marjoram are all good herbs that don’t get too big. Keep herbs pinched back (pinch off top of each branch where flowers would be) to prevent flowering and to help keep bushy and promote more growth. Fertilize every couple weeks with a light water fertilizer…Miracle-Gro is the best. For your garden herbs you can plant the ones that get a bit bigger…lavender, rosemary, dill, oregano, sage, caraway, savory, lemon balm, lemon verbena and what ever else you want. Herbs are easy to grow and usually I let some of each type go to seed at the end of the growing season so they will re-produce for next year. Mulch the garden with good clean straw (by "clean" I mean no weed seed) or some other organic material that you might prefer. Throw your veggie scraps, coffee grounds, egg shells, and any other scraps (except meat) in your garden to keep soil fed…to keep away varmints from rooting through your scraps, you can bury your scraps close to your plants (watch the root systems though). Protect your herb garden in the winter by covering with more straw since it is north-ish facing. Some herbs are perennials and will come back…..if it doesn’t get too cold…check your planting zone and find varieties that will do good in that particular area).
Chilies need a lot of sun and a lot of heat to grow well. The hotter outside it is, the better they like it. Keep roots watered well. If you don’t think that your garden will be in a hot enough position…you can always buy some big pots, put some rocks in bottom for good drainage, fill with moisture retentive potting soil, plant your chilies in them and place on South side of your house in the sun. Fertilize lightly. They are easy to grow and pretty low maintence except for water. Hope some of this info helped….Good luck to the both of you!!
