How Many Plugs of Creeping Thyme Do I Need?

I'm sorry if you are not the man I should ask my question to, but I tried another before and I received no answer. Maybe you could be so kind as to redirect my question.

Sorry we missed your earlier question. We try to be diligent about answering questions. There were some brief times in late May and early June when our mail server was down and some messages were lost; perhaps yours was one of them.

Anyway, I wanted to buy some creeping thyme from you guys and I was wondering if you could tell me:
How many plug packs would I need to cover a 80 feet by 2.5 feet slope. Or would it be better to buy plants? if yes I many should I order?

You can plant creeping thyme at several different spacings. If you are in a hurry and want the thyme to fill in and form a solid mass quickly then you can plant 10 cm or 4 inches apart. If you are more patient and want to spend less money then you can plant as far apart as 20 cm or 8 inches. Here is what you will need to fill in 200 square feet (80 ft x 2.5 ft) depending on the planting density you choose:
10 cm centres: 9 plants per square foot x 200 square feet = 1800 plants
15 cm centres: 4 plants per square foot x 200 square feet = 800 plants
20 cm centres: 2.25 plants per sq. ft. x 200 square feet = 450 plants
There are 120 plugs per plug tray or 12 plugs per plug pack. This is a high demand time for creeping thyme and we have no plug trays available at them moment, but we are accepting orders for delivery in 6-8 weeks. We have about 60 plug packs left. If you want larger plants, we have about 100 pots available at the moment. So, at the moment we have enough plants to cover the area at 15 or 20 cm densities.
Please note that we are almost at the end of our plug pack shipping season: the last plug pack shipment date is June 27. You need to order by June 22 at the latest in order to get included in the shipments that day.
