garlic growers

hi i love garlic and since visting the garlic farm last summer on the isle of wight i decided to grow it myself this year,in the 2nd year of my allotment.

i have elephant garlic (from the garlic farm) which was £9 for 9 cloves,
and 15 solent garlic ..

its all growing well ,elephant garlic was planted end of 0ct 09,,,,solent in feb.

elephant garlic leaves on tips have gone a little bit yellow which i understand is lacking in nitrogen,so going to add some blood and bone meal soon...

any tips drop a note
